and its advantages.
DESCRIPTION OF PREFERRED EMBODIMENTS
[0045] At least the following matters are made clear by the
description of the present specification and the accompanying
drawings.
[0046] A printing apparatus comprises: a scanner unit for reading
an image in an original; an instruction unit for receiving an
instruction from a user and instructing operation of reading the
image with the scanner unit; and a printer unit for printing the
image that has been read on a medium, wherein each reading
operation with the scanner unit is started by receiving an
instruction from the user with the instruction unit when the
reading operation is to be performed with the scanner unit for a
plurality of number of times and a plurality of the images that
have been read are to be printed in their respective predetermined
positions on the medium.
[0047] Such a printing apparatus makes it possible to perform N-up
printing of a new procedure that is different from conventional
N-up printing.
[0048] In the printing apparatus, it is preferable that the
printing apparatus does not comprise an automatic paper supply
device. In this way, it is possible to provide a printing apparatus
that is low in cost.
[0049] In the printing apparatus, it is preferable that before the
scanner unit finishes the plurality of number of times of the
reading operations, the printer unit starts printing, on the
medium, the image that has already been read. In this way, it is
possible to increase the speed in printing.
[0050] In the printing apparatus, it is preferable that the printer
unit: carries the medium intermittently and performs printing on
the medium between the intermittent carries; brings the
intermittent carrying into a standby state before printing of the
image that has already been read is finished; restarts the
intermittent carrying after the next reading operation is started;
and carries the medium maintaining a carry amount of the medium
constant before and after the standby state. In this way, since the
intermittent carrying can be performed at a constant carry amount,
the images printed on the medium become uniform and it is possible
to perform printing with high image quality.
[0051] In the printing apparatus, it is preferable that the printer
unit has a plurality of nozzles that move; and when the plurality
of nozzles move after the next reading operation is started, a
portion of the image that has been read before the standby state
and a portion of the image that has been read after the standby
state are printed on the medium by the plurality of nozzles. In
this way, it becomes possible to print, at the same time, a portion
of the image that has been read before the standby state and a
portion of the image that has been read after the standby state.
That is, it is possible to print the joining section between images
at the same time.
[0052] In the printing apparatus, it is preferable that when there
is an instruction to stop printing during the standby state, the
printer unit: finishes printing the image that has already been
read; and discharges the medium. In this way, it is possible to
print the image that has already been read.
[0053] In the printing apparatus, it is preferable that the printer
unit carries the medium intermittently and performs printing on the
medium between the intermittent carries; the printer unit performs
printing until printing of the image that has already been read is
finished; and if the next reading operation has not started when
printing of the image that has already been read is finished, the
printer unit brings the intermittent carrying into a standby state
until the next reading operation is started. In this way, it is
possible to prevent the images from deteriorating due to the
difference in the printing states (for example, the way in which
the ink dries) before and after standby.
[0054] In the printing apparatus, it is preferable that the
printing apparatus allows the number of the images that are to be
printed on the medium to be changed; and a number of the images
that are read before printing is started differs according to the
number of the images that are to be printed on the medium. In this
way, for example, the number of images that are read before
printing is started for 2-up printing (printing of two images on
one sheet of medium) and the number of images that are read before
printing is started for 4-up printing (printing of four images on
one sheet of medium) are different.
[0055] In the printing apparatus, it is preferable that the printer
unit has nozzles that move in a moving direction; and if a
plurality of the images are to be positioned in the medium along
the moving direction, the printer unit starts printing after the
scanner unit performs the reading operation for all of the images
that are arranged along the moving direction. In this way, printing
is started when image data necessary for the nozzles are ready when
the nozzles are moved.
[0056] In the printing apparatus, while the scanner unit is
performing the reading operation, the printer unit starts printing
the image in the original that is being read by that reading
operation. In this way, the print speed increases.
[0057] In the printing apparatus, it is preferable that the printer
unit is capable of printing, on the medium, the images according to
different print modes; and when the plurality of images that have
been read are to be printed in their respective predetermined
positions on the medium, the printer unit is capable of printing,
on the medium, each of the images according to a different print
mode. In this way, since the print mode can be changed for each
page in the medium, it is possible to enhance the flexibility in
expression of printing on the medium.
[0058] In the printing apparatus, it is preferable that the printer
unit is capable of printing, on the medium, the images according to
a monochrome print mode and a color print mode. In this way, since
changing between the monochrome print mode and the color print mode
becomes possible for each page in the medium, it is possible to
enhance the flexibility in expression of printing on the
medium.
[0059] In the printing apparatus, it is preferable that the
different print modes are quality modes that differ in print
resolution. In this way, since the resolution can be changed for
each page in the medium, it is possible to enhance the flexibility
in expression of printing on the medium.
[0060] In the printing apparatus, it is preferable that the
instruction unit has members for selecting the print modes, each
member being provided for each print mode; and the instruction unit
receives the instruction from the user through the members. For
example, a color copy button for selecting the color print mode and
a monochrome copy button for selecting the monochrome print mode
are provided, and starting of the reading operation of the scanner
section is instructed when these buttons are pressed. In this way,
since the member for selecting the print mode and the member for
instructing the reading operation to start can be shared, it is
possible to reduce the apparatus cost.
[0061] In the printing apparatus, it is preferable that the printer
unit is capable of printing, on the medium, the images according to
different print modes; and when the plurality of images that have
been read are to be printed in their respective predetermined
positions on the medium, the printer unit prints, on the medium,
each of the images according to the same print mode. In this way,
it is possible to simplify user operations and improve
usability.
[0062] In the printing apparatus, it is preferable that the
instruction unit selects the print mode for printing the images on
the medium when it receives an instruction from the user. In this
way, the user can instruct the reading operation and select the
print mode with the instruction unit.
[0063] In the printing apparatus, it is preferable that when the
plurality of images that have been read are to be printed in their
respective predetermined positions on the medium, other images are
printed on the medium according to the print mode that has been
initially selected. In this way, it is possible to simplify user
operations and improve usability.
[0064] In the printing apparatus, it is preferable that it further
comprises a notification device that provides notification of an
error, wherein the notification device provides notification of an
error if a print mode that is different from the initially selected
print mode is selected when the reading operation is performed for
a second time and thereafter. In this way, it is possible to call
the user's attention.
[0065] In the printing apparatus, it is preferable that it further
comprises a display device, wherein the display device displays
information about the initially selected print mode when the
reading operation is performed for a second time and thereafter. In
this way, it is possible to call the user's attention.
[0066] In the printing apparatus, it is preferable that the same
print mode as the initially selected print mode is selected
regardless of the print mode selected when the reading operation is
performed for a second time and thereafter. In this way, it is
possible to prevent errors from occurring.
[0067] In the printing apparatus, it is preferable that the
instruction unit has members for selecting the print modes, each
member being provided for each print mode; and the instruction unit
receives the instruction from the user through the members. For
example, a color copy button for selecting the color print mode and
a monochrome copy button for selecting the monochrome print mode
are provided, and starting of the reading operation of the scanner
section is instructed when these buttons are pressed. In this way,
since the member for selecting the print mode and the member for
instructing the reading operation to start can be shared, it is
possible to reduce the apparatus cost.
[0068] A printing method comprises: instructing a reading operation
when an instruction is received from a user; reading an image in an
original according to the instruction to perform the reading
operation; and printing the image that has been read on a medium,
wherein each reading operation is started by receiving an
instruction from the user when the reading operation is to be
performed for a plurality of number of times and a plurality of the
images that have been read are to be printed in their respective
predetermined positions on the medium.
[0069] Such a printing method makes it possible to perform N-up
printing of a new procedure that is different from conventional
N-up printing.
[0070] A printing apparatus comprises: a scanner unit for reading
an image in an original; and a printer unit for printing the image
that has been read on a medium, wherein when the reading operation
is to be performed with the scanner unit for a plurality of number
of times and a plurality of the images that have been read are to
be printed in their respective predetermined positions on the
medium, the printer unit starts printing, on the medium, the image
that has already been read before the scanner unit finishes the
plurality of number of times of the reading operations.
[0071] Such a printing apparatus makes it possible to increase the
speed in printing.
FIRST EMBODIMENT

data sent from the host computer 3 to be output by the printer
function.
Configuration of Control Panel Section 70
[0078] As shown in FIG. 5, the control panel section 70 is provided
with a liquid crystal display 72 at approximately the center
thereof and a notification lamp 74. The liquid crystal display 72
is capable of displaying thirty two characters, i.e., two lines by
sixteen columns, and is capable of displaying, for example, setting
items, setting states, or operation states using characters. The
notification lamp 74 that is located on the side of the liquid
crystal display 72 is a red LED and notifies the user of occurrence
of errors by lighting up when an error occurs.
[0079] On the left of the liquid crystal display 72 are provided a
power button 76, a scan-start button 78, a setting-display button
80, and a clear button 82. The power button 76 is the button for
turning the power of the present SPC multifunction apparatus 1 ON
and OFF. The scan-start button 78 is the button for causing the
scanner section 10 to start reading the original 5 in a state in
which the SPC multifunction apparatus 1 is connected to the host
computer 3. The setting-display button 80 is the button for making
the liquid crystal display 72 display the setting states for the
copying function that have been set by the user. The clear button
82 is the button for resetting the settings for the copying
function in order to change the setting items to their default
values.
[0080] On the right of the liquid crystal display 72 are provided a
color copy button 84, a monochrome copy button 86, a stop button
88, and number-of-copies-setting buttons 90.
[0081] The color copy button 84 is the button for starting color
copying, and the monochrome copy button 86 is the button for
starting monochrome copying. Therefore, these copy buttons 84, 86
serve both as to instructing the copy operation to start and as
selecting means (a selecting unit) for selecting whether the print
image to be output is in color or monochrome. Specifically, by
pressing either one of the copy buttons 84, 86, print mode
information that specifies by which of the print modes--either
color printing or monochrome printing--printing is performed is
generated, and an input signal including this information is sent
to a CPU 54. It should be noted that the print mode information is
used for the N-up printing process, which is the characteristic
matter of the present invention described later. The stop button 88
is the button for stopping the copying operation that has
started.
[0082] The number-of-copies-setting buttons 90 are made up of two
buttons 901, 902, each having a "+" or a "-" written on its
surface. By pressing the "+" button 901, the setting of the number
of sheets increases, and by pressing the "-" button 902, the
setting of the number of sheets decreases. Further, the
number-of-copies-setting buttons 90 are set so that the number
successively increases or decreases when one of them is
continuously pressed, that the increase or decrease speed becomes
faster as the amount of time pressed becomes longer.
[0083] On the front side of the liquid crystal display 72 are
provided menu buttons 92 for changing the setting items displayed
on the liquid crystal display 72. The menu buttons 92 are made up
of two buttons arranged on the right and left, each having a
rightward arrow or a leftward arrow written thereon. Every time
either the right or left one of the menu buttons 92 is pressed, the
displayed setting items sequentially change according to a
predetermined order, and after all the items have been displayed
once, the first setting item is displayed. The left and right
arrows are for changing the order in which the setting items are
displayed, and each button 92 allows the setting items to be
displayed in the order opposite to the displaying order for when
the other button is pressed. As with the number-of-copies-setting
buttons 90, these menu buttons 92 are also set so that the changing
speed becomes faster by continuously pressing them.
[0084] With these menu buttons 92, it is possible to set a quality
mode for each type of paper. The quality mode relates to the image
quality of the image printed on the paper; that is, by selecting
the quality mode, the print resolution for when printing is
performed by the printer section 30 is mainly determined.
[0085] FIG. 7 exemplifies the quality modes provided for the SPC
multifunction apparatus 1 of the present embodiment. For example,
as for plain paper, three types of quality modes--"economy",
"fast", and "fine"--can be selected, and as for super-fine paper,
two types of modes--"fast" and "fine"--can be selected. Further, as
for glossy paper, PM photo paper, and PM matte paper, which usually
require higher image quality than the plain paper etc., the quality
mode "fine" is provided for each. The user appropriately operates
the menu buttons 92 while looking at the liquid crystal display 72
to input the quality mode. Then, quality mode information generated
according to this input is sent to the CPU 54 along with the input
signal generated by operating the above-mentioned copy buttons.
Configuration of Scanner Section 10
[0086] The scanner section 10 includes the original bed glass 12 on
which the original 5 is placed, the original bed cover 14 for
pressing the surface to be read of the original 5, which is placed
on the original bed glass 12, toward the original bed glass 12, a
reading carriage 16 that is opposed to the original across the
original bed glass 12 and that scans along the original 5 while
maintaining a constant distance from the original 5, drive means 18
for making the reading carriage 16 scan, and a restriction guide 20
for making the reading carriage 16 scan in a stable state.
[0087] The reading carriage 16 includes an exposure lamp 22 serving
as a light source for illuminating the original 5 across the
original bed glass 12, a lens 24 for concentrating the light
reflected from the original 5, four mirrors 26 for guiding the
light reflected from the original 5 to the lens 24, a CCD sensor 28
for receiving the reflected light that has passed through the lens,
and guide receiving sections 29 that engage with the
above-mentioned restriction guide 20.
[0088] The CCD sensor 28 includes three linear sensors in which
photodiodes for converting light signals into electric signals are
arranged in rows, and these three linear sensors are arranged
parallel to each other. The CCD sensor 28 includes three, not-shown
filters for R (red), G (green), and B (blue); a filter for a
different color is provided for each linear sensor. Each linear
sensor detects the light component corresponding to the color of
the filter. For example, the linear sensor with the R filter
detects the intensity of the red light component. The three linear
sensors are arranged in a direction (referred to as the
main-scanning direction below) that is approximately orthogonal to
the moving direction of the reading carriage 16 (referred to as the
sub-scanning direction below).
[0089] The length of the CCD sensor 28 is sufficiently shorter than
the width of the original 5 (the length in the main-scanning
direction) that is readable. Therefore, the image made by the
reflected light from the original 5 is reduced in size by the lens
24 and then formed on the CCD sensor 28. That is, the lens 24
placed between the original 5 and the CCD sensor 28 is arranged
close to the CCD sensor 28. Further, the distance between the
original 5 and the lens 24 needs to be long, and a long optical
path length is required. Therefore, in order to secure the distance
between the original 5 and the lens 24 in the limited space of the
reading carriage 16 that scans, the light is reflected on the four
mirrors 26 to secure the long optical path length.
[0090] The reflected light from the original 5 is reflected by the
four mirrors 26, passes through the lens 24, and reaches the CCD
sensor 28; however, since the three linear sensors are arranged in
parallel, the positions on the original from which the reflected
light that forms an image on each linear sensor at the same time
was reflected are misaligned, in the sub-scanning direction, by an
amount equal to the width of each linear sensor. Therefore, a
scanner control unit 58 (FIG. 11) of the control circuit 50
performs interline correction processing for correcting this
misalignment. The interline correction processing is described
later.
[0091] The above-mentioned restriction guide 20 is provided in the
sub-scanning direction and is formed of a cylindrical material made
of stainless steel. The restriction guide 20 passes through the two
guide receiving sections 29 that are provided on the reading
carriage 16 and that are formed of thrust bearings. By widening the
distance, in the sub-scanning direction, between the two guide
receiving sections 29 provided on the reading carriage 16, it
becomes possible to cause the reading carriage 16 to scan
stably.
[0092] The drive means 18 includes an annular timing belt 181 fixed
to the reading carriage 16, a pulse motor 183 that has a pulley 182
engaging with the timing belt 181 and that is arranged on one end
in the sub-scanning direction, and an idler pulley 184 that is
arranged on the other end and that applies tension force to the
timing belt 181. The pulse motor 183 is driven by the scanner
control unit 58 (FIG. 11) of the control circuit 50; according to
the scan speed of the reading carriage 16 which is changed
according to the speed of the pulse motor 183, it becomes possible
to enlarge or reduce, in the sub-scanning direction, the image that
has been read.
[0093] The scanner section 10 causes the reading carriage 16 to
move along the original 5 while illuminating the original 5 with
the light of the exposure lamp 22 and forming an image on the CCD
sensor 28 with the reflected light. At this time, by reading-in,
according to a predetermined cycle, the amounts of light received
by the CCD sensor 28 as values in voltage, the image for the
distance for which the reading carriage 16 moved during one cycle
is taken in as data for one line of an image to be output. At this
time, three kinds of data--the R component, the G component, and
the B component--are taken in as data for one line.
Configuration of Printer Section 30
[0094] The printer section 30 adopts the inkjet method.
[0095] It uses four colors--cyan (C), magenta (M), yellow (Y), and
black (K)--as basic colors and forms color images by ejecting these
color inks onto a medium, such as print paper, to form dots. It
should be noted that, other than the above-mentioned four colors,
light cyan (pale cyan, LC), light magenta (pale magenta, LM), and
dark yellow (dim yellow, DY) may be used.
[0096] Further, the printer section 30 can perform single-color
printing for outputting monochrome images using only black (K)
color ink. Whether to output a color image or a monochrome image is
based on binary data obtained after binarization processing; the
binary data will be described later.
[0097] Next, with reference to FIG. 3, FIG. 7, and FIG. 8, the
printer section 30 is described. FIG. 7 is an explanatory diagram
showing the arrangement of the surroundings of the print head, and
FIG. 8 is an explanatory diagram for illustrating a drive section
of a print paper carry mechanism.
[0098] As shown in the figures, the printer section 30 has a
mechanism for ejecting ink and forming dots by driving a print head
38 mounted on a writing carriage 36, a mechanism for causing the
writing carriage 36 to move back and forth in a direction
orthogonal to the direction in which the paper 7 is carried by a
carriage motor 40, and a mechanism for carrying the paper 7
supplied from the paper supply tray 321 (see FIG. 1) by the paper
feed motor (referred to also as a PF motor below) 42.
[0099] The mechanism for ejecting ink and forming dots includes the
print head 38 that has a plurality of nozzles serving as ink
ejecting sections, and causes predetermined nozzles to eject ink
according to print command signals. The plurality of nozzles form
rows in the bottom surface 381 of the print head 38 in the carry
direction of the paper 7, and the plurality of rows are arranged in
the direction orthogonal to the carry direction of the paper 7.
Details on the print head 38 and the nozzle arrangement will be
described later. The print head 38 includes a 16-bit memory
associated with each of the nozzles; data is transferred from a
head control unit 68 (FIG. 11), which is described later, to each
nozzle in 16-bit units.
[0100] The mechanism for causing the writing carriage 36 to move
back and forth includes the carriage motor (referred to also as a
CR motor below) 40 for driving the writing carriage 36, a slide
shaft 44 that is provided in the direction orthogonal to the carry
direction of the paper 7 and that slidably holds the writing
carriage 36, a linear encoder 46 fixed to the writing carriage 36,
a linear encoder code plate 461 in which slits are formed at
predetermined intervals, a pulley 48 that is attached to a rotating
shaft of the carriage motor 40, and a timing belt 49 that is driven
by the pulley 48.
[0101] The print head 38 and a cartridge mounting section
integrally provided with the print head 38 are fixed to the writing
carriage 36, and ink cartridges containing inks of black (K), cyan
(C), magenta (M), yellow (Y), and so forth are mounted on the
cartridge mounting section.
[0102] The mechanism that carries the paper 7 supplied from the
paper supply tray 321 has a platen 35 that is arranged opposed to
the above-mentioned print head 38 and that serves as a guiding
member for guiding the paper 7 so that distance between the paper 7
and the print head 38 is appropriate, a carry roller 37 that is
provided upstream from the platen 35 in the carry direction of the
paper 7 and that carries the supplied paper 7 to the platen 35 so
that the paper comes into contact with the platen at a
predetermined angle, a paper discharge roller 39 that is provided
downstream from the platen 35 in the carry direction of the paper 7
and that is for carrying and discharging the paper 7 that has
disengaged from the carry roller 37, the PF motor 42 for driving
the carry roller 37 and the paper discharge roller 39, a rotary
encoder 47 for detecting the amount for which the paper 7 has been
carried, and a paper detection sensor 45 for detecting the presence
of the paper 7 and the front end and the rear end of the paper
7.
[0103] The carry roller 37 is provided underneath the carry path of
the paper 7, and a driven roller 371 for holding the paper 7 is
provided above and in opposition to the carry roller 37. The paper
discharge roller 39 is also provided underneath the carry path of
the paper 7, and a driven roller 391 for holding the paper 7 is
provided above and in opposition to the paper discharge roller 39.
However, the driven roller 391 arranged in opposition to the paper
discharge roller 39 is a roller that is made of a thin plate and
that has fine teeth on its periphery, and thus, the roller 391 is
structured so that ink is not scraped even when the roller comes
into contact with the surface of the printed paper 7.
[0104] Further, the position at which the carry roller 37 and the
paper 7 contact each other is arranged so that it is higher than
the position at which the platen 35 and the paper 7 contact each
other. That is, the paper 7 carried from the carry roller 37 comes
into contact with the platen 35 at a predetermined angle and is
further carried. In this way, the paper 7 is carried along a
later-described guide surface 351 of the platen 35 in such a manner
that it is pressed against the guide surface 351. Therefore, the
platen 35 maintains the paper 7 in a suitable position from the
nozzles, and thus it is possible to obtain a satisfactory
image.
[0105] Further, the carry roller 37 and the paper discharge roller
39 are linked through a gear train 31, and are made to rotate
through transmission of the rotation of the PF motor 42; the speed
at which both rollers 37, 39 carry the paper 7 is the same.
[0106] In opposition to the bottom surface 381 of the print head
38, that is, the surface with the nozzles, the platen 35 has the
guide surface 351 that guides the paper 7 through contact
therewith. This guide surface 351 is formed to be narrower than the
area of the bottom surface 381 of the print head 38 in which the
nozzles are provided, and therefore, some of the nozzles positioned
furthest upstream and furthest downstream in the carry direction of
the paper 7 are not placed in opposition to the platen 35. In this
way, the ink ejected outside the paper 7 is prevented from adhering
to the platen 35 when the front end and the rear end of the paper 7
are printed, and the back surface of paper 7 that is carried later
on is prevented from getting smeared. More specifically, the platen
35 is not arranged in the positions opposing the nozzles at the
upstream end and the downstream end, but rather, there is a space
in those positions. Those space portions are provided with ink
receivers at a position lower than the guide surface 351 of the
platen 35 to collect the unnecessary ink and keep the inside of the
printer from getting smeared.
[0107] The paper detection sensor 45 is arranged upstream from the
carry roller 37 in the carry direction, and has a lever 451 that
has an axis of swinging in a position higher than the carry path of
the paper 7, and a transmission type optical sensor 452 that is
provided above the lever and that has a light emitting section and
a light receiving section. The lever 451 is arranged so that it
hangs down into the carry path under its own weight, and includes
an actuating section 453 that is made to swing by the paper 7
supplied from the paper supply tray 321 and a light-blocking
section 454 that is located on the opposite side of the actuating
section 453 across the axis of swinging and that is arranged to
pass between the light emitting section and the light receiving
section. In the paper detection sensor 45, when the lever 451 is
pushed by the supplied paper 7 and the paper 7 reaches a
predetermined position, the light-blocking section 454 blocks the S
light that has been emitted from the light emitting section, and
thereby, it is detected that the paper 7 has reached the
predetermined position. Then, when the paper 7 is carried by the
carry roller 7 and the rear end of the paper 7 passes by, the lever
451 hangs down under its own weight, the light-blocking section 454
comes out from between the light emitting section and the light
receiving section so that the light from the light emitting section
is received by the light receiving section, and it is detected that
the rear end of the paper 7 reached the predetermined position. In
this way, it is detected that the paper 7 is present at least in
the carry path while the light-blocking section 454 is blocking the
light from the light emitting section.
Regarding the Configuration of the Nozzles
[0108] FIG. 9 is an explanatory diagram showing the arrangement of
nozzles in the bottom surface 381 of the print head 38. In the
bottom surface 381 of the print head 38 are formed a black ink
nozzle row 33(K), a cyan ink nozzle row 33(C), a magenta ink nozzle
row 33(M), and a yellow ink nozzle row 33(Y). Each nozzle row 33
has a plurality of nozzles (ten in the present embodiment) that are
the ejection openings for ejecting ink of each color.
[0109] The plurality of nozzles in each nozzle row 33 are aligned
in the paper carry direction at regular intervals (nozzle pitch:
k.multidot.D). Here, D is the minimum dot pitch in the paper carry
direction (that is, it is the distance between dots formed on the
paper 32 at the highest resolution), and for example, when the
resolution is 720 dpi, D is {fraction (1/720)} inch (approximately
35.3 .mu.m). Further, k is an integer of 1 or more.
[0110] Further, as for the nozzles in each nozzle row 33, nozzles
located further downstream have smaller numbers attached to them,
and each of the nozzles is referred to as the first nozzle N1
through the tenth nozzle N10. Each nozzle is provided with a piezo
element (not shown) as an actuation element for actuating each
nozzle to make it eject ink droplets.
[0111] It should be noted that, during printing, the paper 7 is
intermittently carried by the carry roller 37 and the paper
discharge roller 39 by a predetermined carry amount F, and during
this intermittent carrying, the writing carriage 36 is moved in the
scanning direction and ink droplets are ejected from each of the
nozzles.
Actuating the Print Head
[0112] Next, the actuation of the print head 38 is described below
with reference to FIG. 10. FIG. 10 is a block diagram showing the
configuration of a drive signal generating section provided in the
head control unit 68 (FIG. 11).
[0113] In FIG. 10, the drive signal generating section includes a
plurality of mask circuits 204, an original drive signal generating
section 206, and a drive signal correcting section 230. The mask
circuits 204 are provided corresponding to each of the plurality of
piezo elements for actuating each of the nozzles N1 through N10 of
the print head 38. Note that in FIG. 10, the number in parentheses
attached to the end of each signal name indicates the number of the
nozzle to which the signal is supplied. The original drive signal
generating section 206 generates original drive signals ODRV used
in common among the nozzles N1 through N10. The original drive
signal ODRV is a signal that includes two pulses--a first pulse W1
and a second pulse W2--during the main scan period for one pixel.
The drive signal correcting section 230 performs correction by
shifting, either forward or backward for the whole return pass, the
timing of the drive signal waveform that has been shaped by each
mask circuit 204. By correcting the timing of the drive signal
waveform, the misalignment between the positions at which the ink
droplets land during the forward pass and the return pass is
corrected; that is, the misalignment between the positions at which
the dots are formed during the forward pass and the return pass is
corrected.
[0114] As shown in FIG. 10, input serial print signals PRT(i) are
input to the mask circuits 204 along with the original drive signal
ODRV that is output from the original drive signal generating
section 206. The serial print signal PRT(i) is a serial signal made
of two bits per pixel, and each bit corresponds to the first pulse
W1 and the second pulse W2, respectively.
[0115] Each mask circuit 204 is a gate for masking the original
drive signal ODRV according to the level of the serial print signal
PRT(i). That is, if the serial print signal PRT(i) is at level 1,
the mask circuit 204 lets the corresponding pulse of the original
drive signal ODRV pass right through so that the pulse is supplied
to the piezo element as a drive signal DRV, whereas if the serial
print signal PRT(i) is at level 0, the mask circuit 204 cuts off
the corresponding pulse of the original drive signal ODRV.
Internal Structure of the Control Circuit 50
[0116] FIG. 10 is a block diagram showing an example of a control
circuit 50.
[0117] In the control circuit 50 of the SPC multifunction apparatus
1, the CPU 54 that manages the control over the entire SPC
multifunction apparatus 1, a ROM 55 that stores a program for
executing the control, the control ASIC 51 that manages the control
over the scanner function, the printer function, and the local
copier function, an SDRAM 56 in which data is directly readable and
writable from the CPU 54, and the control panel section 70 serving
as the input means are connected via a bus. The scanner unit 10,
the print head 38, the ASIC-SDRAM 69 in which data is directly
readable and writable from the control ASIC 51, and so forth, are
connected to the control ASIC 51.
[0118] The control ASIC 51 includes the scanner control unit 58, a
binarization processing unit 60, an interlace processing unit 62,
an image buffer unit 64, a CPU interface unit (referred to as a
CPUIF unit below) 66, the head control unit 68, the USB interface
(referred to as a USBIF below) 52 serving as input/output means for
the external host computer 3, and drivers for each of the motors,
lamps, and so forth, that the scanner section 10 and the printer
section 30 comprise. Further, a line buffer 691, an interlace
buffer 692, and an image buffer 693 are allocated to the
control-ASIC-SDRAM 69. In order to achieve increased data transfer
rate, so-called burst transmission, in which the data transfer unit
is 64 bit, is adopted between the control ASIC 51 and the
ASIC-SDRAM 69.
[0119] The scanner control unit 58 has the function of executing
control over the exposure lamp 22, the CCD sensor 28, the pulse
motor 183 serving as a reading carriage drive motor, and so forth,
of the scanner section 10, and the function of sending the data
read in via the CCD sensor 28 to the binarization processing unit
60 via the line buffer 691.
[0120] The binarization processing unit 60 has the function of
converting the multi-gradation RGB data, which has been sent, into
either binary data for each color in CMYK or binary data only for K
and sending the data to the interlace processing unit 62. Whether
the RGB data is to be converted into data of either the binary data
for each color in CMYK or the binary data only for K is determined
according to the above-mentioned print mode information that has
been entered through operation of the copy buttons of the control
panel section 70. That is, the RGB data is accompanied with the
print mode information entered through operation of the copy
buttons. If the print mode information is for the color printing
mode, the RGB data is converted into the binary data for CMYK, and
if it is for the monochrome printing mode, the RGB data is
converted into binary data for K.
[0121] The interlace processing unit 62 has the function of
generating overlap-printing-compliant data (referred to as
OL-compliant data below) by dividing the CMYK data for one raster
line into data for printing per each scan movement of the writing
carriage 36, when so-called overlapped printing is performed in
which one raster line (a line in the main-scanning direction in a
print image) is printed with several number of times of scan
movements of the writing carriage 36. The generated OL-compliant
data is stored in the interlace buffer 692 of the ASIC-SDRAM
69.
[0122] Further, the interlace processing unit 62 has the function
of reading out the data stored in the interlace buffer 692 onto an
SRAM 621 in the interlace processing unit 62 in units of
predetermined size, rearranging the data on the SRAM 621 so as to
associate the data with the nozzle arrangement, and sending the
data to the image buffer unit 64.
[0123] The image buffer unit 64 has the function of generating,
from the data sent from the interlace processing unit 62,
head-drive data for causing each nozzle to eject ink per each scan
movement of the writing carriage 36.
[0124] The CPUIF unit 66 has the function of enabling the CPU 54 to
access the control-ASIC-SDRAM 69 connected to the control ASIC 51.
In the present control circuit 50, the unit 66 is used when the
head control unit 68 is actuated according to the head-drive data
generated by the image buffer unit 64.
[0125] The head control unit 68 has the function of actuating the
print head 38 according to the head-drive data under control of the
CPU 54 to make the nozzles eject ink.
Data Flow in Control Circuit 50
[0126] <As for when Functioning as a Scanner>
[0127] A command signal instructing to read an image with the
scanner unit 10 and read-information data such as the read
resolution and the read area are sent from the host computer 3
connected to the USBIF 52 of the control ASIC 51 to the control
circuit 50. In the control circuit 50, the scanner control unit 58
is controlled by the CPU 54 according to the image-read command
signal and the read-information data, and reading of the original 5
with the scanner unit 10 is started.
[0128] At this time, in the scanner control unit 58, a lamp drive
unit, a CCD drive unit, a reading carriage scan drive unit, and so
forth, are actuated, and RGB data is read from the CCD sensor 28
according to a predetermined cycle. The RGB data having been read
in is temporarily stored in the line buffer 691 allocated to the
ASIC-SDRAM 69, subjected to interline correction processing for
each R, G, and B data, and sent to the host computer 3 via the
USBIF 52. Interline correction processing is a process for
Correcting the misalignment among the reading positions for the R,
G, and B linear sensors, which occurs due to the structure of the
scanner section 10.
[0129] Describing in detail, the CCD sensor 28 that the scanner
unit 10 has is a color sensor and has one line of linear sensor
each for the three colors, R (red), G (green), and B (blue). Since
these three linear sensors are arranged parallel to each other in
the scanning direction of the reading carriage 16, the reflected
light, which was illuminated on the same line in the original 5,
cannot be received at the same time. That is, when the reflected
light, which was illuminated on the same line in the original 5, is
received by each of the linear sensors, there will be a time lag.
Therefore, the process is for synchronizing the pieces of data that
are sent delayed by a delay time that occurs due to the arrangement
of the linear sensors.
[0130] <As for when functioning as a printer>
[0131] When the apparatus functions as a printer, the image data to
be printed is input through the USBIF 52 after being converted, in
a printer driver of the host computer 3 connected to the USBIF 52
of the control ASIC 51, into head-drive data that can be printed by
the printer section 30 of the SPC multifunction apparatus 1. The
head-drive data is data that provides signals for actuating the
print head 38; for example, when printing is performed according to
the interlace mode, the head-drive data is made by extracting
raster data that corresponds to the print resolution and the pitch
and number of nozzles of each nozzle row 33 in the writing carriage
36, and rearranging the raster data in the order to be printed per
each scan movement of the writing carriage 36. It should be noted
that, when printing is performed according to the interlace mode,
the nozzle pitch (the distance between the nozzles) is wider than
the distance between the dots formed on the paper.
[0132] The head-drive data is stored in an image buffer 57 that is
allocated to the SDRAM 56 which is directly readable from the CPU
54. The image buffer 57 has two memory areas each having a capacity
capable of storing head-drive data for printing with one scan
movement of the writing carriage 36. When data for one scan
movement is written into one image buffer 571, the data is
transferred to the head control unit 68. When the image data in one
image buffer 571 is transferred to the head control unit 68,
head-drive data to be used for printing during the next scan
movement is stored in the other image buffer 572. Then, when the
data for one scan movement is written into the other image buffer
572, the data is transferred to the head control unit 68, and image
data is written into the above-mentioned first image buffer 571. In
this way, printing is performed by writing and reading the
head-drive data alternately using two image buffers 571, 572 and
actuating the print head 38 with the head control unit 68.
[0133] <As for when Functioning as a Copier>
[0134] Next, the data flow for when the apparatus functions as a
copier is described. Here, only the data flow for the normal
copying operation is described, and the 2-up printing mode of the
present embodiment will be described later.
[0135] The data having been read in by the scanner unit 10 is taken
into the line buffer 691 via the scanner control unit 58. The RGB
data taken into the line buffer 691 is successively subjected to
the above-mentioned RGB interline correction processing, and the
RGB data corresponding to the same line are sent from the scanner
control unit 58 to the binarization processing unit 60.
[0136] The RGB data sent into the binarization processing unit 60
is subjected to halftone processing. Then, with reference to a
lookup table (LUT) 695 stored in the control-ASIC-SDRAM 69, the
data is converted into either the binary data for each color in
CMYK or the binary data for only K based on the print mode
information accompanying the RGB data, and then the data is sent
into the interlace processing unit 62.
[0137] As for the above-mentioned binary data sent into the
interlace processing unit 62, the whole data for each raster line
is divided into pieces of data to be printed per every scan
movement of the writing carriage 36 according to the designated
interlace mode. For example, when one raster line is formed with
two scan movements of the writing carriage 36, the whole data for
each raster line is divided into data for forming the odd-numbered
dots, counted from the end of the raster line, and data for forming
the even-numbered dots to generate the OL-compliant data. The
OL-compliant data is burst transmitted to the interlace buffer 692
in units of 64 bits and stored there.
[0138] Further, the interlace processing unit 62 reads out the data
stored in the interlace buffer 692 in units of predetermined size,
and burst transmits the data to the SRAM 621 in the interlace
processing unit 62.
[0139] At this time, the OL-compliant data is read out from the
interlace buffer 692 in correspondence with the nozzle arrangement
of the print head 38 according to the print resolution and the
nozzle pitch. For example, when the print resolution is 720 dpi and
the nozzle pitch is {fraction (1/180)} inch, three raster lines
will be printed between two raster lines that have been printed
with adjacent nozzles. Therefore, data for every four raster lines
is read out from the OL-compliant data as data corresponding to a
scan movement of the writing carriage 36.
[0140] The transferred data is rearranged on the SRAM 621 so that
it corresponds to the nozzle arrangement, and is sent to the image
buffer unit 64.
[0141] The image buffer unit 64 burst transmits, to the image
buffer 693, the image data that has been blocked into small pieces
according to the capacity of the SRAM 621, and stores the data in
proper orientation so that it becomes the head-drive data for
making each of the nozzles eject ink per every scan movement of the
writing carriage 36. Memory areas for storing head-drive data for
two scan movements of the writing carriage 36 are allocated to the
image buffers 693, 694. Every time head-drive data for one scan
movement is stored, the CPU 54 sends it out to the head control
unit 68, and head-drive data corresponding to the next scan
movement starts to be written into the memory area provided for
another scan movement. This process is the same as the process of
the image buffers described above in the description of the printer
function.
[0142] Under control of the CPU 54, the head-drive data for each
scan movement stored in the image buffers 693, 694 is read into the
CPU 54 via the CPUIF unit 66 and transferred to the head control
unit 68 by the CPU 54. The head control unit 68 actuates the print
head 38 according to the head-drive data to print the image.
N-Up Printing Mode of the Present Embodiment
[0143] Below, N-up printing is described, taking 2-up printing as
an example.
[0144] FIG. 12 is a diagram for illustrating the 2-up printing mode
(copying mode) of the present embodiment. In the figure, 5A is the
first original and has an image "A" on its surface. Further, 5B is
the second original and has an image "B" on its surface. 7 is the
single sheet of paper printed by the SPC multifunction apparatus 1.
On this paper 7, the image "A" and the image "B" are printed,
according to 2-up printing, respectively in each print area formed
by dividing the surface of the paper 7 into half. That is, the
image "A" read from the first original 5A is printed on the print
area for the first page which is on the left side of the paper 7,
and the image "B" read from the second original 5B is printed on
the print area for the second page which is on the right side. It
should be noted that the above-mentioned page refers to each print
area formed by dividing the surface of a sheet of paper into equal
parts; for example, as for the 2-up printing mode, the left print
area is referred to as the first page and the right area is
referred to as the second page. Further, as for 4-up printing mode,
a page means each print area formed by dividing the surface of the
paper 7 into four equal parts, and each area is called the first
through fourth page, respectively.
[0145] According to the present embodiment, the print mode for the
image "A" on the first page and that for the image "B" on the
second page, which is adjacent to the first page, can be set
independent of each other when the first sheet of paper 7 is being
printed. Therefore, it is possible to print one of either the image
"A" or the image "B" by monochrome printing and print the other one
by color printing. That is, the image in each page, which is
printed next to each other in a predetermined position of the
single sheet of paper 7, can be set for either the monochrome
printing or the color printing on a page-by-page basis, and
therefore, it is possible to enhance the flexibility in expression
of printing on the medium.
[0146] It should be noted that, in the present embodiment, as shown
in FIG. 12, a margin is provided between the end of the paper and
each image. Further, a margin is provided between each image.
[0147] <About the Processing Operation of 2-up Printing>
[0148] FIG. 13 is a flowchart for illustrating the procedure of the
processing operation of the 2-up printing of the present
embodiment. The figure shows the operation flow for the scanner
section 10, the control circuit 50 (or the control panel section
70), and the printer section 30 of the SPC multifunction apparatus
1.
[0149] Below, the 2-up printing mode of the present embodiment is
described using FIG. 12 and FIG. 13. It should be noted that a
program relating to the procedure of the processing operation of
the 2-up printing is stored in the ROM 55.
[0150] First, the user sets paper 7 in the paper supply tray of the
SPC multifunction apparatus 1 (S121). In the following description,
it is assumed that a plurality of single-sheet print paper in A4
size is set. It should be noted that the user may enter information
about the paper 7 by operating the various buttons on the control
panel section 70.
[0151] Next, the user operates the various buttons on the control
panel section 70 to select the "2-up printing" of the present
embodiment from a plurality of print modes (S111). That is, first,
the user successively changes the setting items that have been
displayed using the menu buttons 92 to go to the display screen
"copy mode", which is the setting item to be set. Next, the user
sets the setting value to "2-up printing" by pressing the two
buttons 901, 902. In this way, the 2-up printing mode is selected
as the print mode of the SPC multifunction apparatus 1. Further, in
the same way, the user operates the various buttons on the control
panel section 70 to set the size of the width t of the margin. In
this way, the SPC multifunction apparatus 1 obtains information
about the margin (margin information). If, however, the width t of
the margin is not set through the control panel section 70, a
default value that is set in advance is used as the preset value
for the margin width. In the present embodiment, the margin
information indicates that the width is t (mm).
[0152] Next, the user sets the first original 5A, as the first
sheet of original, on the scanner section 10 of the SPC
multifunction apparatus 1 (S101). The way in which the first
original 5A is set is described using FIG. 14A. First, the user
opens the original bed cover 14 and places the first original 5A on
the original bed glass 12. When the first original 5A is placed on
the original bed glass 12, the user faces the side on which the
image "A" is written downwards and places a corner of the first
original 5A against the origin mark at a corner of the original bed
glass 12. Then, the user closes the original bed cover 14 to make
the original bed cover 14 press the first original 5A on the
original bed glass 12 against the original bed glass 12. In this
way, the first original 5A is set on the scanner section 10.
[0153] Next, the user instructs the operation of reading the first
sheet of original 5A to start. Since the apparatus is already set
to perform the 2-up printing (S111), the reading operation starts
when the user presses the color copy button 84 or the monochrome
copy button 86 of the control panel section 70 (S112).
[0154] It should be noted that, as described above, the print mode
for printing on the paper 7 the image for the first page that has
been read from the first original 5A is determined by operating the
copy button. That is, if the monochrome copy button 86 is pressed,
the monochrome print mode information, which is entered through
this copy button operation, accompanies the later-described read
data (RGB data) that is read from the first original 5A, and
conversely, if the color copy button 84 is pressed, the color print
mode information, which is entered through this copy button
operation, accompanies the data. Here, in order to facilitate
understanding of the description, it is assumed that the monochrome
copy button 86 is pressed to carry out monochrome printing for the
first original 5A.
[0155] Next, the scanner section 10 of the SPC multifunction
apparatus starts operating to read the image "A" in the first
original 5A (S102). While the scanner section 10 is reading the
image "A" in the original 5A, read data (RGB data) is output from
the CCD sensor according to a predetermined cycle. It should be
noted that, in the present embodiment, the linear sensors of the
CCD sensor are aligned parallel to the lateral direction of the
image "A", and the reading carriage 16 performs its scan movement
parallel to the vertical direction of the image "A". (That is, in
the present embodiment, the image "A" in the first original 5A of
FIG. 12 is read by the scanner section 10 from the top toward the
bottom.) Therefore, the read data that is output from the scanner
section is data formed by successively outputting line data that is
in the lateral direction of the image "A".
[0156] Next, the control circuit 50 of the SPC multifunction
apparatus generates head-drive data based on the read data that is
successively sent from the scanner section 10 (S113a, S113b, S113c,
S114a). The head-drive data generated at this time is data for
printing the image "A" part of the print image "AB" in the paper 7
of FIG. 12. The head-drive data is generated according to the
above-mentioned monochrome print mode information accompanying the
read data of the image "A" in the first original 5A, and as a
result, the head-drive data is structured of data for causing only
the K (black) nozzles to actuate. Therefore, the image "A" part in
the paper 7 is printed in monochrome. It should be noted that the
process of generating the head-drive data according to the read
data will be described later. The generated head-drive data is
successively sent to the head control unit 68.
[0157] In the present embodiment, the print image "AB" is printed
on the paper 7 by scan-moving the writing carriage 36 parallel to
the short-side direction of the paper 7 and carrying the paper 7 in
the long-side direction of the paper 7. (That is, in the present
embodiment, the print image "AB" on the paper 7 of FIG. 12 is
printed from left to right.) Therefore, the head-drive data will be
data formed by successively outputting line data that is in the
vertical direction of the image "A". As a result, the printer
section 30 is able to start printing the image "A" even before the
head-drive data for the image "B" is generated. Therefore, in the
present embodiment, printing is started for the image "A" that has
already been read from the first original 5A before finishing
reading the image "B" in the second original.
[0158] The printer section 30 starts printing according to the
head-drive data that is successively sent to the head control unit
68 (S122). It should be noted that, when the process of generating
the head-drive data for the image "A" is finished (S114b), no
head-drive data will be sent to the head control unit 68.
Therefore, the printer section 30 stops its printing operation and
enters a print-standby state (a state in which various operations,
such as the operation of carrying the paper 7 and the printing
operation of ejecting ink, are in standby) (S123).
[0159] After the operation of reading the first original 5A is
finished, the liquid crystal display 72 of the SPC multifunction
apparatus 1 displays a message prompting the user to change
originals. Confirming this message, the user changes the first
original 5A that is set on the scanner section 10 to the second
original 5B. The way in which the originals are changed is
described using FIG. 14B. First, the user opens the original bed
cover 14 and takes out the first original 5A placed on the original
bed glass 12. Then, the user sets the second original 5B as a
second sheet of original. It should be noted that, since the
procedure of setting the second original 5B is the same as the
procedure of setting the first original 5A described above,
description thereof is omitted.
[0160] It should be noted that in the present embodiment, printing
of the image "A" of the print image "AB" is started before reading
of the image "B" in the second original 5B is started. Therefore,
in the present embodiment, a portion of the print image is already
discharged from the paper discharge section 34 when the originals
are being changed (refer to FIG. 14B).
[0161] After changing the originals, the user instructs the
operation of reading the second sheet of original 5B to start. The
operation of reading the second sheet of original 5B is also
started when the user presses the color copy button 84 or the
monochrome copy button 86 on the control panel section 70 (S115).
It should be noted that, as with the first original 5A described
above, the print mode for printing on the paper 7 the image for the
second page that has been read from the second original 5B is
determined by the copy button operation for the second original 5B.
That is, the print mode for the image on the second page, which is
the above-mentioned second original 5B, can be set independent of
the first original 5A. Here, in order to facilitate understanding
of the description, it is assumed that the color copy button 84 is
pressed for the second original 5B, and the color print mode
information accompanies the later-described read data (RGB data)
read from the second original 5B.
[0162] Next, the scanner section 10 of the SPC multifunction
apparatus 1 starts operating to read the image "B" in the second
original 5B (S105). While the scanner section 10 is reading the
image "B" in the original 5B, read data (RGB data) is output from
the CCD sensor according to a predetermined cycle.
[0163] Next, the control circuit 50 of the SPC multifunction
apparatus generates head-drive data based on the read data that is
successively sent from the scanner section 10 (S116a, S116b, S116c,
S117a). The head-drive data generated at this time is data for
printing the image "B" part in the paper 7 of FIG. 12. The
head-drive data is generated according to the above-mentioned color
print mode information accompanying the read data of the image "B"
in the second original 5B, and as a result, the head-drive data is
structured of data for causing the nozzles of the four colors CMYK
to actuate. Therefore, the image "B" part in the paper 7 is printed
in color. It should be noted that the process of generating the
head-drive data according to the read data will be described later.
The generated head-drive data is successively sent to the head
control unit 68.
[0164] The printer section 30 restarts printing according to the
head-drive data that is successively sent to the head control unit
68 (S124). That is, after the operation of reading the image "B" is
started, the printer section 30 restarts the carry operation of
intermittently carrying the paper 7, the printing operation of
ejecting ink from the nozzles that move in the scanning direction,
and so forth.
[0165] When printing is finished (S117b, S125), the paper 7 is
discharged from the paper discharge section 34. On the discharged
paper 7, there will be printed a print image "AB", as shown in the
paper 7 of FIG. 12. It should be noted that the image "A" part of
the print image "AB" is printed in monochrome, whereas the image
"B" part is printed in color.
[0166] After the operation of reading the second original is
finished, the liquid crystal display 72 of the SPC multifunction
apparatus displays a message prompting the user to take out the
second original. Confirming this message, the user takes out the
second original 5B that is set on the scanner section 10.
[0167] <About the Data Flow in Control Circuit 50 During 2-up
Printing>
[0168] FIG. 15 is a block diagram showing an example of the control
circuit 50 when 2-up printing is performed. In FIG. 11 described
above, two buffers--the image buffers 571, 572 (or the image
buffers 693, 694)--were depicted for alternately performing writing
and reading. In FIG. 15, however, in order to simplify the
description, the two buffers for alternately performing writing and
reading are not depicted.
[0169] Although the hardware configuration is the same as the
control circuit 50 in FIG. 11 described above, the allocation of
the memory area in the SDRAM 56, which is directly readable from
the CPU 54, is different. Further, in FIG. 11 described above, the
CPU 54 only accesses the image buffer 694. In FIG. 15, however, the
CPU 54 accesses the line buffer 691 and the interlace buffer 692
via the CPUIF unit 66. Further, the memory area allocation of the
interlace buffer 692 is divided into two, and therefore, the buffer
692 is logically made of two buffers.
[0170] Below, the data flow in the control circuit 50 when 2-up
printing is performed is described using FIG. 15. It should be
noted that a program for controlling the data flow in the control
circuit 50 when 2-up printing is performed is stored in the ROM 55.
In the description above, one raster line was formed by two scan
movements of the writing carriage 36. However, in order to simplify
the description, here, one raster line is formed by one scan
movement of the writing carriage 36. (That is, description is made
below in a state in which the dot data of the raster line is not
divided into the odd-numbered data and the even-numbered data.)
[0171] (1) First, the data flow in the control circuit 50 from when
the image "A" is read from the first sheet of original (first
original 5A) (S102) until printing is started (S122) is
described.
[0172] Receiving an input signal of the color copy button 84 or the
monochrome copy button 86 from the control panel section 70 after
the "2-up printing" is set, the CPU 54 sends control signals to the
scanner control unit 58. These control signals include the print
mode information based on the copy button operation; since the
monochrome copy button 86 is pressed in this example, the
monochrome print mode information is included. By the way, the
monochrome print mode information is effective until the next copy
button operation; that is, the later-described RGB data generated
by the scanner section 10 during this period is accompanied with
the monochrome print mode information.
[0173] The scanner control unit 58 controls the scanner section 10
according to the above-mentioned control signals from the CPU 54 to
start the operation of reading the image "A" from the first
original 5A.
[0174] It should be noted that, since the image "A" of the first
original 5A is printed on the paper 7 reduced in size, the scanner
control unit 58 reads the image "A" from the first original 5A so
that data is thinned out compared to when the image "A" is read at
scale 1/1. That is, the data in the lateral direction of the image
"A" is reduced in size by thinning out the data that is obtained
from the line sensors of the CCD sensor. This thinning-out process
is performed by the scanner control unit 58 thinning out the output
data from the line sensors. Further, the data in the vertical
direction of the image "A" is reduced in size by increasing the
scanning speed of the reading carriage. This process is performed
by the scanner control unit 58 controlling the scanning speed of
the reading carriage so that the speed becomes faster. By thinning
out the data of the image "A" in both lateral and vertical
directions in this way, the image "A" is read substantially reduced
in size.
[0175] The scanner control unit 58 controls the scanner section 10
to take the RGB data output from the CCD sensor at a predetermined
cycle into the line buffer 691. Then, the scanner control unit 58
subjects the RGB data, which has been temporarily taken into the
line buffer 691, to the RGB interline correction processing
(described above), and then sends the RGB data for the same line
into the binarization processing unit 60.
[0176] The binarization processing unit 60 subjects the RGB data,
which has been taken in, to halftone processing. Then, the
binarization processing unit 60 refers to the lookup table (LUT)
695 stored in the control-ASIC-SDRAM 69 to convert the
halftone-processed data into either the binary data for each color
in CMYK or the binary data only for K (black). It should be noted
that the conversion into the binary data is performed according to
the above-mentioned print mode information; for example, since the
above-mentioned RGB data accompanies the monochrome print mode
information in the present example, the data is converted into the
binary data only for K (black). The binarization unit 60 sends the
binary data only for K into the interlace processing unit 62.
[0177] The interlace processing unit 62 takes the binary data only
for K, which has been sent in from the binarization processing unit
60, into one interlace buffer (referred to as the first interlace
buffer 692A) of the interlace buffers that have been divided into
two. Then, the binary data taken into the first interlace buffer
692A is sent, via the CPU interface unit 66, into a layout buffer
573 in the SDRAM 56 that is directly readable from the CPU 54.
[0178] The layout buffer 573 is a buffer allocated to the SDRAM,
and is logically divided into two areas. The binary data that has
been sent from the first interlace buffer 692A is taken into one
layout buffer (the first layout buffer) 573A of the two areas. The
other layout buffer (the second layout buffer (also called the
intermediate buffer)) 573B stores layout image data that is
generated based on the binary data in the first layout buffer 573A,
as described later.
[0179] FIG. 16 is a conceptual diagram of the binary data sent into
the first layout buffer 573A. This binary data is stored in a
continuous memory area, but when it is wrapped around according to
the width of the image, it becomes the image information as shown
in the figure. (In this description, a single piece of image
information is obtained because it is assumed that one raster line
is formed by one scan movement of the writing carriage 36, in order
to simplify the description.)
[0180] The CPU 54 generates layout image data based on the binary
data taken into the first layout buffer 573A. However, only an area
capable of storing only several lines of line data for the lateral
width of paper is allocated to the second layout buffer 573B for
storing the generated layout image data. Therefore, the CPU 54
generates linear layout image data and sends the generated layout
image data into the second layout buffer 573B. The layout image
data for several lines having been sent into the second layout
buffer 573B are then successively sent into the second interlace
buffer 692B in the control-ASIC-SRAM 69.
[0181] In the present embodiment, the read data that is output from
the scanner section is data in which line data in the lateral
direction of the image "A" have been successively output.
Therefore, binary data in the lateral direction of the image "A"
are successively sent into the first layout buffer. On the other
hand, it is necessary that the head-drive data be data in which
line data in the vertical direction of the image "A" have been
successively output. Therefore, in the present embodiment, the
first layout buffer 573A once takes in the whole data of the image
"A", and when the CPU 54 generates the layout image data in the
second layout buffer, it performs a process of turning the data of
the image "A" and then successively generates the line data in the
vertical direction (data that has been turned) of the image "A". As
a result, the data successively sent from the second layout buffer
573B to the second interlace buffer 692B become line data in the
vertical direction of the image "A", and therefore, it becomes
possible to successively generate, based on these data, the
head-drive data in the vertical direction of the image "A".
[0182] FIG. 17A through FIG. 17G are conceptual diagrams of the
layout image data sent into the second layout buffer 573B. The
layout image data is stored in a continuous memory area, but when
it is wrapped around according to the width of the image and
rearranged, it becomes the layout image (a portion of the print
image) for several lines in the vertical direction as shown in the
figure.
[0183] The layout image data is generated as follows. First, the
CPU 54 generates null data for the margin to generate image data
corresponding to the margin from the upper end of the paper up to
the image (the margin on the left of the image "A") (FIG. 17A, FIG.
17B). After the null data amounting to the width of the margin has
been generated, the CPU 54 generates a layout image in which line
data (binary data) in the vertical direction of the image "A" taken
into the first layout buffer 573A are successively arranged (FIG.
17B). When the line data in the vertical direction of the image "A"
are being arranged, the CPU 54 inserts null data amounting to the
width of the margin from the side end of the paper up to the image.
In this way, margins in the lateral direction (margins on the top
and bottom of the image "A") are generated in the layout image. The
line data in the vertical direction of the image "A" are generated
only for the area in the lateral direction of the image "A" (FIG.
17B through FIG. 17F). After finishing generating the layout image
for the area of the image "A", the CPU 54 again generates null data
for the margin to generate image data for the margin between the
images (FIG. 17F, FIG. 17G). In this way, a margin in the vertical
direction (the margin on the right of the image "A") is generated
in the layout image. It should be noted that the layout image data
that are generated as above whenever necessary are successively
sent into the second interlace buffer 692B in the control-ASIC-SRAM
69. It should be noted that the layout image data that are sent
into the second interlace buffer 692B are the above-mentioned
binary data only for K.
[0184] The processes that are performed after the binary data (the
layout image data) have been sent from the second layout buffer
573B into the second interlace buffer 692B are almost the same as
the processes for when the apparatus functions as a copier as
described above. That is, the following processes are performed.
(However, to simplify the description, description on the process
of alternately performing writing and reading is omitted.)
[0185] The interlace processing unit 62 reads out the data stored
in the second interlace buffer 692B in units of predetermined size,
and burst transmits the data to the SRAM 621 in the interlace
processing unit 62.
[0186] At this time, the binary data is read out from the interlace
buffer 692 in correspondence with the nozzle arrangement of the
print head 38 according to the print resolution and the nozzle
pitch. For example, when the print resolution is 720 dpi and the
nozzle pitch is {fraction (1/180)} inch, three raster lines will be
printed between two raster lines that have been printed with
adjacent nozzles. Therefore, data for every four raster lines is
read out from the binary data as data corresponding to a scan
movement of the writing carriage 36.
[0187] The transferred data is rearranged on the SRAM 621 so that
it corresponds to the nozzle arrangement, and is sent to the image
buffer unit 64.
[0188] The image buffer unit 64 burst transmits, to the image
buffer 693, the image data that has been blocked into small pieces
according to the capacity of the SRAM 621, and stores the data in
proper orientation so that it becomes the head-drive data for
making each of the nozzles eject ink per every scan movement of the
writing carriage 36.
[0189] Under control of the CPU 54, the head-drive data for each
scan movement stored in the image buffers 693, 694 is read into the
CPU 54 via the CPUIF unit 66 and transferred to the head control
unit 68 by the CPU 54. The head control unit 68 actuates the print
head 38 according to the head-drive data to print the image. Here,
the head-drive data is formed from the binary data only for K;
therefore, only the K (black) nozzles are actuated in the print
head 38 and thereby black ink droplets are ejected only from the K
nozzles. In this way, in the present embodiment, it is possible to
arrange the image "A" in the paper 7 as shown in FIG. 12 and to
print the image "A" part in monochrome.
[0190] (2) Next, the data flow in the control circuit 50 from when
printing has started (S122) up to the print-standby state (S123) is
described.
[0191] FIG. 18 is an explanatory diagram showing how printing is
performed before the image "B" in the second sheet of original (the
second original) is read. As already explained, the head-drive data
for the image "A" (and the margin portions surrounding it) are
successively stored in the image buffer. When the head-drive data
for the first scan movement is stored, the stored head-drive data
is sent out to the head control unit 68 by the CPU 54. Then, when
the head moves in the scanning direction, ink droplets are ejected
from the nozzles in the head according to the head-drive data.
Therefore, the head-drive data necessary for pass 1 (the first scan
movement) through pass 8 in the figure can be sent out successively
to the head control unit 68 after the image "A" in the first sheet
of original (first original) has been read.
[0192] On the other hand, the head-drive data necessary for pass 9
(the ninth scan movement) requires head-drive data for the image
"B" in the second original. That is, if the image "B" in the second
original has not been read, the head-drive data (data corresponding
to a plurality of nozzles) necessary for pass 9 is not stored in
the image buffer 693 (that is, the head-drive data has not been
assembled); therefore, it is not possible to actuate the head for
pass 9. As a result, before the head-drive data for the image "B"
of the second original is generated, the printer section cannot
print the image that is in the position of pass 9.
[0193] Therefore, in the present embodiment, the scan movement of
the writing carriage 36 is stopped and the apparatus is in the
print-standby state at the point where printing has finished for
pass 8 (the eighth scan movement). That is, printing for the part
to be printed in pass 9 and there after is not finished. Therefore,
in the present embodiment, the apparatus enters the standby state
in the middle of printing a portion of the image "A" of the first
original (the right-side portion of the image "A") that is to be
printed on the paper.
[0194] It should be noted that in the present embodiment, if the
clear button 82 is pressed and there is an instruction to stop
printing during the standby state, the SPC multifunction apparatus
1 completes printing the image "A" of the first original,
discharges the paper 7, and then terminates printing. This is
because the image "A" will be in a half-finished state if the paper
7 is discharged as it is when the apparatus is in the standby
state.
[0195] (3) Finally, the data flow in the control circuit 50 from
when the second sheet of original (the second original) is set
until printing is completed is described.
[0196] After the operation of reading the first original 5A is
finished, the CPU 54 displays on the liquid crystal display 72 a
message indicating to change originals. After the originals have
been changed, the CPU 54 receives an input signal from the color
copy button 84 or the monochrome copy button 86, and sends control
signals to the scanner control unit 58. These control signals also
include the print mode information according to the copy button
operation. That is, in this example, since the color copy button 84
is pressed as described above, the color print mode information is
included. By the way, the color print mode information is effective
until the next copy button operation; that is, the later-described
RGB data generated by the scanner section 10 during this period is
accompanied with the color print mode information.
[0197] The scanner control unit 58 controls the scanner section 10
according to the above-mentioned control signals from the CPU 54 to
start the operation of reading the image "B" from the second
original 5B.
[0198] It should be noted that, if generation of the head-drive
data of the image "A" is still not finished when the input signal
of the color copy button 84 or the monochrome copy button 86 is
received, the CPU 54 first finishes generating the head-drive data
for the image "A" (or enters the standby state) and then sends the
control signals to the scanner control unit 58. This is because it
is necessary to reserve enough area in the memory (the SDRAM 56 or
SDRAM 69) necessary for generating the head-drive data for the
image "A". That is, by starting the operation of reading the second
original after generation of the head-drive data for the first
original has finished (or after the apparatus enters the standby
state), it is possible to make the memory small.
[0199] The scanner control unit 58 controls the scanner section 10
to take the RGB data, which are output from the CCD sensor at a
predetermined cycle, into the line buffer 691. Then, the scanner
control unit 58 subjects the RGB data, which has been temporarily
taken into the line buffer 691, to the RGB interline correction
processing (described above), and then sends the RGB data for the
same line into the binarization processing unit 60.
[0200] The binarization processing unit 60 subjects the RGB data,
which has been taken in, to halftone processing. Then, the
binarization processing unit 60 refers to the lookup table (LUT)
695 stored in the control-ASIC-SDRAM 69 to convert the
halftone-processed data into either the binary data for each color
in CMYK or the binary data only for K (black). It should be noted
that the conversion into the binary data is performed according to
the above-mentioned print mode information; for example, since the
above-mentioned RGB data accompanies the color print mode
information in the present example, the data is converted into the
binary data for each color in CMYK. The binarization unit 60 sends
the binary data for each color in CMYK into the interlace
processing unit 62.
[0201] The interlace processing unit 62 takes the binary data for
each color in CMYK, which has been sent in from the binarization
processing unit 60, into the first interlace buffer 692A. Then, the
binary data taken into the first interlace buffer 692A is sent, via
the CPU interface unit 66, into the first layout buffer 573A in the
SDRAM 56 that is directly readable from the CPU 54.
[0202] The CPU 54 generates linear layout image data based on the
binary data taken into the first layout buffer 573A. The CPU 54
sends the generated layout image data into the second layout buffer
573B. Then, the layout image data for several lines that have been
sent into the second layout buffer 573B are successively sent into
the second interlace buffer 692B in the control-ASIC-SRAM 69. It
should be noted that the layout image data sent into the second
interlace buffer 692B is the above-mentioned binary data for each
color in CMYK.
[0203] The interlace processing unit 62 reads out the data stored
in the second interlace buffer 692B in units of predetermined size,
and burst transmits the data to the SRAM 621 in the interlace
processing unit 62.
[0204] At this time, the binary data is read out from the interlace
buffer 692 in correspondence with the nozzle arrangement of the
print head 38 according to the print resolution and the nozzle
pitch. For example, when the print resolution is 720 dpi and the
nozzle pitch is {fraction (1/180)} inch, three raster lines will be
printed between two raster lines that have been printed with
adjacent nozzles. Therefore, data for every four raster lines is
read out from the binary data as data corresponding to a scan
movement of the writing carriage 36.
[0205] The transferred data is rearranged on the SRAM 621 so that
it corresponds to the nozzle arrangement, and is sent to the image
buffer unit 64.
[0206] The image buffer unit 64 burst transmits, to the image
buffer 693, the image data that has been blocked into small pieces
according to the capacity of the SRAM 621, and stores the data in
proper orientation so that it becomes the head-drive data for
making each of the nozzles eject ink per every scan movement of the
writing carriage 36.
[0207] Then, the head-drive data for the image "B" (and the margins
surrounding it) are successively stored in the image buffer. When
the head-drive data for one scan movement is stored, the stored
head-drive data is sent out to the head control unit 68 by the CPU
54. Then, when the head moves in the scanning direction, ink
droplets are ejected from the nozzles in the head according to the
head-drive data. Since the head-drive data is made from the binary
data for each color in CMYK, each of the CMYK nozzles of the print
head 38 is actuated, and therefore, ink droplets are ejected from
each of the CMYK nozzles. In this way, in the present embodiment,
it is possible to arrange the image "B" in the paper 7 as shown in
FIG. 12 and to print the image "B" part in color.
[0208] It should be noted that in the present embodiment, the
head-drive data for the image "A" for pass 9 (refer to FIG. 18)
(the head-drive data for the right-side portion of the image "A")
is not accumulated (is not assembled) until the head-drive data for
the image "B" is generated. Therefore, the data is not sent out to
the head control unit 68. Thus, the head-drive data for the image
"A" for pass 9 remains in the image buffer until the head-drive
data for the image "B" is generated (that is, until the operation
of reading the image "B" is started). After the operation of
reading the image "B" is started, the head-drive data for the
left-side portion of the image "B" is stored in the image buffer,
in which the head-drive data for the image "A" still remains. When
the head-drive data for the scan movement for pass 9 is accumulated
in the image buffer, the accumulated drive data is sent out by the
CPU 54 to the head control unit 68, and printing is restarted.
(That is, after the head-drive data for the image "B" has been
generated, the printer section 30 restarts the carry operation of
intermittently carrying the paper 7, the printing operation of
ejecting ink from the nozzles that move in the scanning direction,
and so forth.) Therefore, the head-drive data in pass 9 is
head-drive data generated based on the image "A" and the image "B".
Therefore, the right-side portion of the image "A" and the
left-side portion of the image "B" are both printed, at the same
time, in pass 9.
[0209] It should be noted that, considering the head-drive data for
pass 9 from the standpoint of print modes, this head-drive data is
structured of a portion that is made up of binary data only for K
and a portion that is made up of binary data for each color in
CMYK. That is, the portion of the head-drive data that corresponds
to the above-mentioned right-side portion of the image "A" is data
made up of the binary data only for K for actuating only the K
nozzles, whereas the portion of the head-drive data that
corresponds to the above-mentioned left-side portion of the image
"B" is data made up of the binary data for each color in CMYK for
actuating each of the CMYK nozzles. Therefore, during pass 9, ink
droplets are ejected only from the K nozzles for the right-side
portion of the image "A", whereas ink droplets are ejected from the
CMYK nozzles for the left-side portion of the image "B". Therefore,
it is possible to perform printing with different print modes even
during a scan pass that is used for both images "A" and "B".
[0210] In this way, in the present embodiment, it is possible to
perform printing such that the print image "AB" is arranged in the
paper 7 as shown in FIG. 12. Further, in this print image "AB", it
is possible to print the image "A" part in monochrome and print the
image "B" part in color.
[0211] It should be noted that attention should be paid to the fact
that the present SPC multifunction apparatus 1 does not have an
automatic document feeder (ADF). The present SPC multifunction
apparatus 1 improves, for example, the operability of the user in
cases where a plurality of images are read so that they are printed
together on a piece of print-recording medium while the user
manually changes originals, without using an ADF.
[0212] By the way, in the present embodiment, the SPC multifunction
apparatus 1 starts the 2-up printing after having finished reading
the entire first original because it is necessary to subject the
image data to a turning process when 2-up printing is performed.
However, if the images are to be arranged without subjecting the
image data to the turning process, the head-drive data for one pass
will be stored even before finishing reading the first original,
and therefore, the SPC multifunction apparatus will be able to
start printing the image of the first original while operating to
read the first original. In this way, since printing is started
earlier, the printing speed becomes faster. It should be noted
that, in the same way, printing of the image of the second original
may be started before finishing reading the second original.
Configuration of Computer System Etc.
[0213] Next, an embodiment of a computer system, a computer
program, and a storage medium having a computer program recorded
thereon is described with reference to the drawings.
[0214] FIG. 19 is an explanatory diagram showing the external
configuration of a computer system. The computer system 1000
includes: a computer unit 1102; a display device 1104; an SPC
multifunction apparatus 1106; an input device 1108; and a reading
device 1110. In the present embodiment, the computer unit 1102 is
housed in a mini-tower casing; however the structure is not limited
to this example. Although a CRT (cathode ray tube), a plasma
display, or a liquid crystal display device is generally used as
the display device 1104, any other kinds of devices can be used.
The SPC multifunction apparatus described above is used as the SPC
multifunction apparatus 1106. In the present embodiment, a keyboard
1108A and a mouse 1108B are used as the input device 1108; however,
any other kinds of devices can be used. In the present embodiment,
a flexible disk drive device 1110A and a CD-ROM drive device 1110B
are used as the reading device 1110; however, it is also possible
to use an MO (Magnet Optical) disk drive device, a DVD (digital
versatile disk) drive, or any other kinds of devices.
[0215] FIG. 20 is a block diagram showing the-configuration of the
computer system shown in FIG. 19. FIG. 20 shows that an internal
memory 1202, such as a RAM, provided inside the casing in which the
computer unit 1102 is housed, and an external memory, such as a
hard-disk drive unit 1204, are also provided.
[0216] The above-mentioned computer program for controlling the
operations of the printer may be downloaded to, for example, the
computer 1000 connected to the SPC multifunction apparatus 1106 via
a communications line such as the Internet. It is also possible,
for example, to record the program on a computer-readable storage
medium and distribute it in this form. It is possible to use
various kinds of storage media such as flexible disks FDs, CD-ROMs,
DVD-ROMs, magneto-optical disks MOs, hard disks, and memories, as
the storage medium. It should be noted that the information
recorded on such a storage medium can be read by various kinds of
teading devices 1110.
[0217] FIG. 21 is an explanatory diagram showing a user interface
of a printer driver displayed on the screen of the display device
1104 that is connected to the computer system. The printer driver
serves as a complement to the printer function of the SPC
multifunction apparatus. The user can carry out various settings of
the printer driver using the input device 1108.
[0218] The, user can select the print mode from this screen. For
example, the user can select the high-speed printing mode or the
fine printing mode as the print mode. Further, the user can select
the distance between dots (the resolution) for printing from this
screen. For example, the user can select, from this screen, 720 dpi
or 360 dpi as the print resolution.
[0219] FIG. 22 is an explanatory diagram of a format of print data
supplied to the SPC multifunction apparatus 1106 from the computer
unit 1102. The print data is generated from the image information
according to the settings of the printer driver. The print data
includes a print condition command group and command groups for
each pass. The print condition command group includes commands
indicating the print resolution, commands indicating the printing
direction (unidirectional/bidirectional), and so forth. Further,
the print command group for each pass includes a target carry
amount command CL and a pixel data command CP. The pixel data
command CP includes pixel data PD indicating the recording status
for each pixel of the dots recorded in that pass. It should be
noted that, although the various commands shown in the figure each
has a header and a data portion, they are depicted in a simplified
fashion. Further, these command groups are intermittently supplied
from the computer unit to the printer on a command-by-command
basis. The print data, however, is not limited to this format.
[0220] It should be noted that in the above description, an example
in which the SPC multifunction apparatus 1106 is connected to the
computer unit 1102, the display device 1104, the input device 1108,
and the reading device 1110 to configure the computer system was
described. However, the configuration is not limited to the above.
For example, the computer system may be configured comprising only
the computer unit 1102 and the SPC multifunction apparatus 1106,
and it does not have to comprise any one of the display device
1104, the input device 1108, or the reading device 1110. Further,
for example, it is also possible for the SPC multifunction
apparatus 1106 to have some of the functions or mechanisms of each
of the computer unit 1102, the display device 1104, the input
devices 1108, and the reading device 1110. For example, it is
possible to structure the SPC multifunction apparatus 1106 so that
it comprises an image processor for processing images, a display
section for performing various kinds of displaying, and a recording
media mounting section for detachably mounting a recording medium
on which image data captured with a digital camera or the like is
stored.
[0221] A computer system configured as above will be superior to
existing computer systems as a whole.
Modification of the First Embodiment
[0222] The above-mentioned embodiment mainly describes an SPC
multifunction apparatus and so forth, but it is needless to say
that the description includes disclosures of printing apparatuses,
printing methods, computer systems, and computer programs.
[0223] Further, an SPC multifunction apparatus etc. according to an
embodiment was described. The above-mentioned embodiment, however,
is for facilitating understanding of the present invention and is
not intended for the present invention to be interpreted limited to
this. The present invention may be modified and/or altered without
departing from the gist thereof, and it is needless to say that the
present invention includes its equivalents. Particularly, even the
embodiments described below are included in the present
invention.
[0224] <About the Number of Originals and Number of
Pages>
[0225] In the above-described embodiment, images for two pages were
read from two sheets of originals, the print mode for each image in
each page was set independent of each other, and the images were
printed on one sheet of paper. The number of originals and the
number of pages to be set on one sheet of paper, however, is not
limited to two. For example, the embodiment is also applicable to
4-up printing as in the explanatory diagram shown in FIG. 23A. That
is, in FIG. 23A, an image for one page is obtained from each of
four sheets of originals through a total of four times of reading
operations, and each of these images is printed in each page on
paper 7. As with 2-up printing described above, even in this 4-up
printing, the print mode for each image for each page that has been
read is set by carrying out the above-described copy button
operation every time the reading operation for each original is
performed.
[0226] 4-up printing, however, differs from the above-mentioned
2-up printing in terms that the timing for starting printing is
different and that the image-turning process is unnecessary. That
is, in 4-up printing, after reading image "A" in the first sheet of
original (first original), the binary data therefor is sent into
the first layout image buffer 573A on the CPU 54 side. Printing is
not started right after this, but instead, image "B" in the second
sheet of original (second original) is read. The binary data for
the image "B" is sent into the first layout image buffer 573A on
the CPU 54 side.
[0227] It should be noted that since the data amount is small
because each of the images is reduced in size compared to the
above-described embodiment, the first layout image buffer 573A is
able to store both data for the image "A" and the image "B". Then,
the CPU generates, in the second layout image buffer 573B, the
linear layout image data based on the data for the two images that
are in the first layout image buffer 573A. In the present
embodiment, it is not necessary to turn the image when the layout
image data is generated, compared to the above-described
embodiment. The data flow after this is approximately the same as
that for the above-described embodiment.
[0228] Further, in the present embodiment, the apparatus enters the
print-standby state before finishing printing the lower part of the
image "A" and the lower part of the image "B". The printing is then
restarted after the reading operations for image "C" in the third
sheet of original and image "D" in the fourth sheet of original are
finished.
[0229] FIG. 22B is a diagram for illustrating another 4-up
printing. In this figure, the order in which the images are
arranged is different compared to the case for the above-mentioned
4-up printing. In this case, printing cannot be started until the
image "C" in the third sheet of original is read. That is, in case
of 4-up printing, the 4-up printing in FIG. 22A, in which the
images that have been read are arranged parallel to the scanning
direction of the writing carriage, is advantageous because it is
possible to start printing earlier. In 4-up printing in FIG. 22B,
however, similar effects can be obtained in terms that it is
possible to start printing before reading the image "D" in the
fourth sheet of original. In this 4-up printing, however, it is
necessary to reserve, in the memory (SDRAM 56 or SDRAM 69), area
that can store data for three images.
[0230] As is clear from the 4-up printing, the number of sheets of
originals and the number of images printed on paper may be four.
Further, the number of sheets of originals and the number of images
printed on paper may be any number. For example, N images may be
read from N sheets of originals, and a print image in which N
images are arranged on paper may be printed (N-up printing). In
this case, it would advantageous if the images that have been read
are arranged on the paper parallel to the scanning direction of the
writing carriage 36, because it would possible to start printing
earlier.
[0231] <About the Print Mode>
[0232] The print mode according to the above-described embodiment
was defined as determining which of either monochrome or color the
image in each of the pages, which are printed arranged in one sheet
of paper, is to be printed in; however, the print mode is not
limited to this as far as it is a parameter for defining print
specifications of an image. For example, the above-mentioned
quality mode for defining the print resolution of the image may be
used as the print mode. That is, it is possible to configure the
apparatus so that the print resolution can be set to be different
for each page by entering, from the above-mentioned control panel
section 70, the quality mode of the image for the page
corresponding to each original every time the reading operation is
performed for each of the originals.
[0233] According to such a configuration, printing can be performed
by changing the above-mentioned print resolution of the image for
each page, and therefore, it is possible to improve the flexibility
in the expression of printing on paper.
[0234] <About the Medium>
[0235] The medium according to the above-described embodiment was a
sheet of paper; however, it is not limited to this as long as it is
a single medium in which the above-mentioned images for a plurality
of pages can be arranged and printed in predetermined positions.
For example, it may be a sheet of cloth, film, and so forth, and
further, it may be a medium of a three-dimensional shape such as a
can.
[0236] <About Image Data Corresponding to one Page>
[0237] The image data corresponding to one page according to the
above-described embodiment was read data for one sheet of original
that has been read by the scanner section 10; however, the image
data is not limited to this as long as it is data that enables
printing of a predetermined image with respect to each print area
formed by dividing the surface of a sheet of paper into equal
parts. For example, the concept of the image data includes text
data (document data that is made up only of character information)
that enables printing of a page of document.
[0238] <About the Method for Obtaining Image Data>
[0239] In the above-described embodiment, the RGB image data (read
data) was obtained by reading the original with the scanner section
10; however, the method for obtaining image data is not limited to
this. For example, a data reading section for reading image data
from a recording medium such as a memory card may be provided on
the above-mentioned SPC multifunction apparatus 1, and N-up
printing may be performed based on N pieces of image data that have
been read.
[0240] <About the Nozzles>
[0241] In the foregoing embodiments, ink was ejected using
piezoelectric elements; however, the method for ejecting liquid is
not limited to this. Other methods may also be employed, such as a
method for generating bubbles in the nozzles using heat.
[0242] <About the Standby Mode>
[0243] According to the above-described embodiment, the printing
operation entered a standby state before printing of the image "A"
is finished. The timing for the standby state, however, is not
limited to this.
[0244] FIG. 23 is a diagram for illustrating another print mode.
According to this figure, the relative movement distance of the
head from pass 6 through pass 9 is made small compared to the
relative movement distance between each pass for the prior passes.
In this way, it is possible to print the image "A" regardless of
whether the head-drive data for the image "B" is going to be
generated or not. If the reading operation for the image "B" has
not been started when printing of the image "A" is finished, the
carrying operation of the paper 7 (or the printing operation of
ejecting ink from the nozzles) is brought into a standby state
until the reading operation for the image "B" is started.
Accordingly, the timing for the standby state may be after printing
of the image "A" is finished.
[0245] According to this embodiment, since the operation does not
enter the standby state in the middle of printing the image "A", it
is possible to prevent the image from deteriorating due to
differences in the printing state (such as the difference in the
way the ink dries before and after standby).
[0246] On the other hand, if there is not much of a difference in
drying of ink, then the above-described embodiment allows the
entire image "A" to be printed evenly because the relative movement
distance of the head before and after entering the standby state is
constant (or the relative movement distance of the head before and
after printing the joining section between the image "A" and the
image "B" is constant).
[0247] <About the Margins>
[0248] In the above-described embodiment, margin portions were
provided between the image and the ends (the upper end or side
ends) of the paper. Further, in the above-described embodiment, a
margin portion was provided between the images. The margin
portions, however, do not have to be provided. It should be noted
that when no margin is provided between the image and the ends of
the paper, then it is preferable not to provide a margin between
the images.
[0249] Further, in the above-described embodiment, a margin was
simply provided between the images. However, a cut-off line may be
provided in the margin portion. This enables easier cutting when
the plurality of images printed on the paper are cut.
SECOND EMBODIMENT
[0250] Below, the second embodiment is described in detail with
reference to FIG. 25 through FIG. 33. As described below, in the
present embodiment, the print mode that is used for the first image
is used for all the other images when a plurality of images are
read and when they are laid out and printed on a piece of
print-recording medium.
[0251] FIG. 25 is a block diagram showing a configuration of
functions of the SPC multifunction apparatus 2001 according to the
present example. The SPC multifunction apparatus 2001 (the SPC
multifunction apparatus is also a type of printer) is configured to
include a control panel 2010, a scan mechanism 2030, a print
mechanism 2040, and a main control section 2050, as will be
described later. More specifically, the SPC multifunction apparatus
2001 at least comprises a scanner function for reading an image
from an original and turning the image into digital data, and a
printer function (a copier function) for printing the digital data
that has been read on print paper. Further, although this is
omitted from the figures, the SPC multifunction apparatus 2001
comprises, for example, the function of receiving image data from a
computer device, such as a digital camera and a personal computer,
and printing it. Further, other than this, the SPC multifunction
apparatus 2001 can read in image data from an attachable/detachable
memory device (not shown) and print this, or write the image data
read with the scanner function into the memory device; description
of these functions is omitted because they are not the main points
of the present invention.
[0252] Further, it should be noted that the present SPC
multifunction apparatus. 2001 does not have an automatic document
feeder (ADF). The present SPC multifunction apparatus 2001 improves
the user operability etc. in cases where the user manually changes
originals so that a plurality of images are read and they are
printed together on a piece of print-recording medium, without
using an ADF.
[0253] The control panel 2010 is provided on the surface of the SPC
multifunction apparatus 2001 in consideration of visibility and
operability, and provides a man-machine interface having an
information entering section 2010A and an information output
section 2010B. The information entering section 2010A includes, for
example, a plurality of information entering means such as a color
copy button 2011A, a monochrome copy button 2011B, and a menu
button 2012. The information output section 2010B includes, for
example, a display 2021 and a lamp 2022. It should be noted that
details on the control panel 2010 will be described later with FIG.
28.
[0254] The scan mechanism 2030 is provided, for example, in the
upper section of the SPC multifunction apparatus 2001. The scan
mechanism 2030 comprises a light source 2031, a light receiving
section 2032, and a scanning section 2033 for making the light
receiving section 2032 move in a predetermined direction. This scan
mechanism 2030, an original bed 2035, an original bed cover 2034,
and a scanner control section 2053, which are described later,
structure a scanner device. The light receiving section 2032 can be
made up, for example, of a plurality of line CCDs (Charge Coupled
Device), each having RGB color filters. The types of color filters,
however, is not limited to RGB. The light from the light source
2031 is reflected from the surface of an original and becomes
reflected light that includes the color of the object. The
reflected light reaches the light receiving section 2032, via a
lens, reflection mirrors, and so forth, and is converted by the
light receiving section 2032 into electric signals. The structure
of the optical system of the scanner device is not limited to the
above and various structures may be adopted. For example, it is
possible to use a reduced-size optical system made up of CCDs
shorter than the image-reading surface of the original bed 2035, a
lens, and a plurality of reflection mirrors, or it is possible to
use CCDs having substantially the same length as the image-reading
surface. Alternatively, it is possible to structure the system
using spectral elements such as a diffraction grating.
[0255] The print mechanism 2040 is provided, for example, in the
lower section of the SPC multifunction apparatus 2001. The print
mechanism 2040 comprises a print head 2041, a scanning section 2042
for making the print head 2041 move in a predetermined direction,
and a paper carrying section 2043 for carrying print paper. This
print mechanism 2040, a paper supply tray 2044, a paper discharge
tray 2045, and a printer control section 2057, which are described
later, structure a printer device. The print head 2041 is
structured comprising, for example, a multitude of nozzles for
ejecting ink droplets in each colors, for example, of cyan,
magenta, yellow, and black, and drive elements for making each of
the nozzles eject ink droplets. The scanning section (carriage)
2042 comprises a carriage motor etc., and makes the print head 2041
move back and forth in a main-scanning direction that is orthogonal
to the print-paper carrying direction (sub-scanning direction). The
paper carrying section 2043 comprises a paper end detecting sensor,
a paper feed motor, etc., and carries the print paper by
predetermined amounts. The print mechanism 2040 can be structured
to be, for example, a serial type print engine that enables
printing character by character, or a line type print engine that
enables printing line by line.
[0256] The main control section 2050 is configured as a
microcomputer system comprising, for example, a processing unit
(CPU etc.), memory devices (ROM, RAM, etc.), input/output circuits,
and so forth. Further, the main control section 2050 may comprise a
dedicated hardware circuit (ASIC (Application Specific Integrated
Circuit)) for executing certain processing. The main control
section 2050 comprises a print mode setting section 2051, a print
mode storage section 2052, the scanner control section 2053, a scan
data storage section 2054, an image processing section 2055, a
print image data storage section 2056, the printer control section
2057, a key input control section 2058, an error notification
section 2059, and an operation guiding section 2060, each of which
being described later. These functions are achieved by hardware
circuits or software, or through cooperation of hardware circuits
and software.
[0257] The print mode setting section 2051 is for applying, to
image reading and image printing, the print mode (copy mode) that
is first instructed through either the color copy button 2011A or
the monochrome copy button 2011B of the control panel 2010. The
initially instructed print mode is stored in the print mode storage
section 2052. The print mode storage section 2052 is formed, for
example, from a memory device such as a RAM.
[0258] The scanner control section 2053 is for making the scan
mechanism 2030 drive to read the image in the original placed on
the original bed 2035 when execution of printing is instructed
through either the color copy button 2011A or the monochrome copy
button 2011B during the later-described N-up printing. The scanner
control section 2053 stores the image data (scan data), which has
been read, in the scan data storage section 2054. The scan data
storage section 2054 is configured, for example, from a memory
device such as a RAM.
[0259] The image processing section 2055 reads in the scan data
stored in the scan data storage section 2054 to generate image data
for printing by performing predetermined image processing. The
print image data generated by the image processing section 2055 is
stored in the print image data storage section 2056. The print
image data storage section 2056 may be structured, for example,
from a memory device such as a RAM. The image processing section
2055 generates the print image data for driving the print head 2041
by performing, for example, color conversion processing from the
RGB color system to the CMYK color system, size-enlargement
processing, size-reduction processing, turning processing, various
kinds of correction processing, and halftone processing. The
printer control section 2057 obtains the print image data from the
print image data storage section 2056, transfers it to the print
head 2041, and makes the head perform predetermined printing.
Further, the printer control section 2057 also controls the
operation of the scanning section 2042 and the paper carrying
section 2043.
[0260] The key input control section 2058 is for setting, as valid,
only button operations corresponding to the print mode that has
been initially designated by the user when N-up printing is
performed, that is, the print mode that is set by the print mode
setting section 2051, and setting operations of other buttons as
invalid. For example, when the initially designated print mode is
the color mode, only operations of the color copy button 2011A are
regarded as valid in the operations for the second time and
thereafter, whereas operations of the monochrome copy button 2011B
are regarded as invalid. In the same way, when the button that is
initially operated by the user in N-up printing is the monochrome
copy button 2011B, only operations of the monochrome copy button
2011B are regarded as valid in the operations for the second time
and thereafter, whereas operations of the color copy button 2011A
are regarded as invalid. In the present example, the
validation/invalidation of key input operations is controlled
electrically or by software. However, this is not a limitation, and
a configuration in which the button operations are controlled
mechanically may also be adopted.
[0261] The error notification section 2059 is for issuing
predetermined warnings when a button corresponding to a print mode
other than the print mode that is set by the print mode setting
section 2051, that is, the print mode that has been initially
selected by the user in N-up printing (which can also be referred
to as the initially selected print mode) is operated. For example,
when the color copy button 2011A has been operated first and the
color mode has been set, the error notification section 2059
displays, an error message on the display 2021 if the user operates
the monochrome copy button 2011B. In the same way, when the
monochrome mode has been set, the error notification section 2059
displays an error message on the display 2021 if the user operates
the color copy button 2011A. Displaying of an error message on the
display 2021 is not a limitation, and an error may be notified to
the user, for example, by reading out a warning sentence with a
voice synthesizer, or by lighting up the lamp 2022.
[0262] The operation guiding section 2060 is for notifying the user
of the print mode that is set by the print mode setting section
2051 in the second operation and thereafter when N-up printing is
performed. For example, when receiving a scan-finished signal from
the scanner control section 2053, the operation guiding section
2060 displays, before the next operation is performed, the
initially set print mode on the display 2021 to call the user's
attention. For example, when the user's first execution instruction
is the color mode, the operation guiding section 2060 displays,
after reading of the image in the original according to this first
execution instruction is finished, a message on the display 2021 to
give some advice for the next execution instruction, and prompts
the user to operate the color copy button 2011A.
[0263] Next, an external configuration of the SPC multifunction
apparatus 2001 is described according to FIG. 26 and FIG. 27. FIG.
26 shows a state in which the original bed cover 2034 is closed.
The scan mechanism 2030 is provided in the upper section of the SPC
multifunction apparatus 2001, and the print mechanism 2040 is
provided in the lower section of the SPC multifunction apparatus
2001. Further, the control panel 2010 is provided on the front face
in the upper section of the SPC multifunction apparatus 2001.
Furthermore, the paper supply tray 2044 is provided on the rear
surface of the SPC multifunction apparatus 2001, and the paper
discharge tray 2045 is provided on the front face in the lower
section of the SPC multifunction apparatus 2001. The SPC
multifunction apparatus 2001 is configured in this way as a
multifunction apparatus that has the scan mechanism 2030 and the
print mechanism 2040 built into the same housing.
[0264] FIG. 27 shows a state in which the original bed cover 2034
is opened. When the original bed cover 2034 is opened, the original
bed 2035 appears in the upper section of the SPC multifunction
apparatus 2001. The original bed 2035 is formed, for example, in a
flat shape from transparent glass material, and below the original
bed 2035 are arranged the light source 2031, the light receiving
section 2032, and so forth. The user positions the original 2002 on
the original bed 2035 placing its face downwards, closes the
original bed cover 2034, and instructs the scanning to start. When
image reading is finished, the user opens the original bed cover
2034, takes out the original 2002 from the original bed 2035, and
places a new original 2002 on the original bed 2035. In the present
example, since the scan range is determined in beforehand, a new
image is read by changing originals 2002. However, this is not a
limitation, and it is also possible to read a plurality of images
from the same original 2002 if it is possible to variably set the
scan range.
[0265] FIG. 28 is an explanatory diagram showing the exterior of
the control panel 2010. In the central section of the control panel
2010 is provided, for example, the display 2021 made of a liquid
crystal display. The display 2021 has the ability to display, for
example, seven lines by sixteen columns (full size characters). On
one side of the display 2021 (towards the right in the figure),
there are arranged various buttons 2011A through 2011C relating to
execution instructions (relating to starting) and various buttons
2013A through 2013E relating to menu operations. On the other side
of the display 2021 (towards the left in the figure), there are
arranged various buttons 2014A through 2014E for selecting various
processing-manner modes that can be executed during stand-alone
operation, a paper supply/paper discharge button 2015, a power
button 2016, and the lamp 2022 for error notification.
[0266] Functions of each of the buttons etc. are described. The
color copy button 2011A is for instructing execution of color
copying. The monochrome copy button 2011B is for instructing
execution of monochrome copying. The color copy button 2011A and
the monochrome copy button 2011B achieve both the execution
instructing function for instructing the copying operation to
start, and the selection function for selecting the type of image
(color image or monochrome image) to be copied. The stop button
2011C is for terminating a process. The menu button 2013A is for
selecting the menu to be displayed on the display 2021. The enter
button 2013B is for confirming the contents of the selected
instructions. The cancel button 2013C is for canceling the contents
of the selected instructions. The cross key button 2013D is for the
operation of switching the display contents of the items in the
menu displayed on the display 2021.
[0267] The SPC multifunction apparatus 2001 of the present example
includes a plurality of processing manners such as local copying,
memory card printing, film printing, and scanning. The copy button
2014A is for selecting local copying. The memory card print button
2014B is for selecting the mode for reading out image data from a
memory card mounted to the SPC multifunction apparatus 2001 and
printing it. The film print button 2014C is for selecting the mode
for reading images from a film such as a 35 mm film or a slide film
and printing them. The scan mode button 2014D is the button for
selecting the mode for, for example, recording an image read from
an original into a memory card mounted on the SPC multifunction
apparatus 2001, sending such an image to a host computer, and so
forth. The various settings button 2014E is, for example, for
adjusting the contrast of the display 2021, cleaning the print head
2041 and checking the nozzles thereof, displaying details on the
remaining amount of ink, exchanging ink cartridges, and so
forth.
[0268] Further, the paper supply/paper discharge button 2015 is for
instructing paper supply operations and paper discharge operations.
The power button 2016 is for controlling power supply to the SPC
multifunction apparatus 2001. The lamp 2022 is for calling the
user's attention by lighting up in case an error occurs.
[0269] Next, operations of the present example are described with
reference to FIG. 29 through FIG. 33. First, a summary of N-up
printing is described according to FIG. 29 and FIG. 30. N-up
printing as used in this example is for laying out and printing N
pieces of images (N being a natural number of two or greater) on
one sheet of print paper. In the present example, two images (2-up
printing) or four images (4-up printing) are laid out and printed
on a single sheet of image. It should be noted that, according to
the relationship between the size of the images that are read and
the size of the print paper on which the plurality of images are
printed together, the images that have been read are subjected to
size-reduction processing and are arranged according to a
predetermined layout for printing on the print paper.
[0270] As shown in FIG. 29, when 2-up printing is performed, the
first original 2002A is first placed on the original bed 2035 and
an image is read therefrom. Next, after reading of the first image
is finished, the first original 2002A is removed from the original
bed 2035, a second original 2002B is placed on the original bed
2035, and reading of the second image is instructed.
[0271] FIG. 30 is a schematic diagram showing how two images that
have been read are laid out on one sheet of print paper and
printed. Each image is laid out on the print paper in, for example,
the same direction as the direction in which it is placed on the
original bed 2035. That is, a layout in which size-reduction
processing is possible while maintaining the ratio in the vertical
and horizontal directions is selected. However, this is not a
limitation, and it is possible to lay the two images out according
to various layouts. When the first image "A" has been read, the
image processing section 2055 immediately starts generating print
image data based on the first scan data. For example, when the
print image data for one scan movement is generated, the print
mechanism 2040 starts printing. In this way, printing is performed
before reading of all the images that make up the 2-up printing is
finished, but from the image that has been read. As shown by the
diagonally shaded section in FIG. 30, the second image "B" is in a
print-data-generation-wait (image-read-wait) state, and will not be
printed just by finishing printing the first image. 2-up printing
is once interrupted until the second image is read and the print
image data therefor is generated. Printing is restarted when the
second image has been read and the print image data has been
generated. It should be noted that, if both the first image and the
second image are read at once, 2-up printing is performed at once
without any interruption in printing.
[0272] 4-up printing in which four images are laid out on one piece
of print paper and printed is performed in the same way as 2-up
printing. As shown in FIG. 31, an example in which four images are
arranged in twos in the vertical and horizontal directions is
described. In this case, the first image is "A", the second image
is "B", the third image is "C", and the fourth image is "D". When
the first and second images are read and print image data for one
scan movement or a plurality of scan movements are generated,
printing of the first and second images is started. The third and
fourth images still have not been read, and therefore, they are in
a print-wait state.
[0273] FIG. 32 is a flowchart showing the N-up printing process.
When the user instructs N-up printing according to the print menu
2012 displayed on the display 2021, the processes shown in FIG. 32
are started. The description below is mainly about 2-up
printing.
[0274] First, the main control section 2050 obtains various setting
values for N-up printing instructed by the user (S2001). It is
possible to list, for example, a copy layout selection value (the
selection of the number of images to be laid out on one sheet of
print paper), the number of copies to be made, printing scale, type
of print paper (plain paper, glossy paper, etc.), paper size, and
copy quality, as the various setting values. The configuration may
be that initial values, which are set in advance, are forcefully
selected for some setting values among the above and those values
cannot be changed.
[0275] After setting the various setting values and placing the
first original on the original bed 2035, the user operates one of
either the color copy button 2011A or the monochrome copy button
2011B to instruct the N-up printing to start (S2002). When either
the color copy button 2011A or the monochrome copy button 2011B is
operated (S2002: YES), it is determined whether or not this is the
first time an image is read in the N-up printing (S2003). If it is
not the first image reading (S2003: NO), the later-described
mode-already-selected processing is performed.
[0276] If it is the first image reading (S2003: YES), then it is
determined which of either the color copy button 2011A or the
monochrome copy button 2011B has been operated (S2005). If
execution of the first image reading has been instructed through
the color copy button 2011A (S2005: YES), then the initially
selected color mode is stored in the print mode storage section
2052 (S2006). Then, the scanner control section 2053 reads the
image from the original placed on the original bed 2035 according
to the color mode (S2007). On the other hand, if the user has
instructed the N printing to start through the monochrome copy
button 2011B (S2005: NO), the monochrome mode is stored in the
print mode storage section 2052 as the initially selected print
mode (S2008), and the scanner control section 2053 reads the image
according to the monochrome mode (S2009). As described later, in
the present example, the initially selected print mode (the color
mode or the monochrome mode) is used for all of the images relating
to the N-up printing.
[0277] The images that have been read by the scan mechanism 2030
according to either the color mode or the monochrome mode are
stored in the scan data storage section 2054 (S2010). The image
processing section 2055 reads out from the scan data storage
section 2054 the images that have been read, and arranges these
images according to a predetermined copy layout to generate print
image data (S2011). The generated print image data is stored in the
print image data storage section 2056.
[0278] When print image data for one or a plurality of number of
times of scan operation(s) has been generated, the printer control
section 2057 drives the print mechanism 2040 to start printing
(S2012). As for 2-up printing, printing is started when the first
image has been read and print image data that allows the printing
to start has been generated. As for 4-up printing, printing is
started when the first and second images have been read and print
image data that allows the printing to start has been
generated.
[0279] The main control section 2050 allows the printing to start
(S2012), as well as counts the number of images that have been read
(S2013). Then, the main control section 2050 determines whether or
not the counted number of images that have been read has reached
the number of images that has been set in S2001 (S2014). If all of
the images relating to N-up printing have not been read (S2014),
then the process returns to S2003, and the image reading process
for the second time and thereafter is executed. That is, the user
removes the first original from the original bed 2035, sets the
second original, closes the cover 2034, and operates the start
button (color copy button or monochrome copy button) to execute the
processing for the second time and thereafter.
[0280] In the present example, S2003 and S2004 are provided for
using the initially selected print mode for all of the images
relating to N-up printing. As for the start operation for the
second time and there after (S2003: NO), the mode-already-selected
processing, which is shown in detail in FIG. 33, is started. In the
mode-already-selected processing, first, the print mode that is
stored in the print mode storage section 2052 is read out and
obtained (S2021).
[0281] Next, with the key input control section 2058, only the copy
button that corresponds to the already-selected print mode is made
valid (S2022). Further, by displaying a guidance message M1 on the
display 2021 with the operation guiding section 2060, the valid
copy button is indicated to the user (S2023). As for the guidance
message M1, it is possible to use a message such as "Please set the
second original on the original bed and press the color mode
button" (if the initially selected print mode is the color
mode).
[0282] The main control section 2050 monitors whether or not the
user operated the valid copy button (S2024), and if the valid copy
button is operated (S2024: YES), the mode-already-selected
processing is ended and the process proceeds to S2005 in FIG. 32.
On the other hand, if the user operates the invalid copy button
even though the guidance message M1 is shown on the display 2021
(S2024: NO), the error notification section 2059 displays an error
message M2 on the display 2021 (S2025) to call the user's
attention. As for the error message M2, it is possible to use a
message such as "Color copying has been selected. This monochrome
copy button is invalid. Please press the color copy button". The
error message M2 can be made up of a section notifying the print
mode that has already been selected, a section notifying the
invalid copy button that has been operated, and a section
indicating the valid copy button that should be operated. When the
user operates the valid copy button according to this error message
M2 (S2024: YES), the mode-already-selected processing ends.
[0283] According to the present embodiment configured in this way,
it is possible to simplify user operations and improve usability
because the initially selected print mode is used for all images
for the second time and thereafter when N-up printing is performed.
Particularly, the operability is improved because the initially
selected print mode is automatically applied to other images, even
in cases where the number of images to be laid out on a sheet of
print paper is large or in cases where a task is restarted after a
temporary interruption.
[0284] Further, since only the copy button corresponding to the
initially selected print mode is made valid and other copy buttons
are made invalid, it is possible to prevent user misoperation.
[0285] Furthermore, if the user operates an invalid copy button, it
is possible to call the user's attention since an error message M2
is displayed.
[0286] Further, convenience is improved because the print mode that
has been initially set is guided to the user by the guidance
message M1 when images are read for the second time and
thereafter.
[0287] Further, the user can get hold of the initially selected
print mode as well as perform N-up printing at once, based on the
print results according to prior printing because before reading
all of the images relating to the N-up printing, printing is
started from parts that are printable.
[0288] It should be noted that the above-mentioned embodiments are
examples given for explanation, and the scope of the present
invention is not to be limited only to those embodiments. Persons
skilled in the art will be able to work the present invention
according to various other embodiment without departing from the
gist thereof.
[0289] For example, the color copy button and the monochrome copy
button may be configured as light-up type buttons with built-in LED
lamps etc., and it is possible to call the user's attention by
lighting up or flashing only the valid copy button corresponding to
the initially selected print mode.
[0290] Further, for example, it is possible to provide a sensor for
detecting the opening and closing of the original bed cover 2034,
and when operations are performed for the second time and
thereafter, it is possible to instruct image reading and printing
according to the already-set print mode at the time when the
original bed cover 2034 is closed.
[0291] Furthermore, in the present example, cases in which two or
four images are laid out and printed on one sheet of print paper
were described; however, this is not a limitation, and it is
possible to lay three, or even five or more images out on a sheet
of print paper and print them.
[0292] Further, in S2001 of FIG. 32, a case in which the paper size
was also obtained as one of the various kinds of setting values was
described; however, it is possible to fix, to fixed values, all or
some of the various setting values, such as the paper size and
paper type, when N-up printing is performed.
[0293] Further, in the present embodiment, if the initially
designated print mode is the color mode, only operations of the
color copy button 11A were regarded as valid in the operations for
the second time and thereafter, and operations of the monochrome
copy button 11B were regarded as invalid. However, the method of
using, for other images, the print mode that has been used for the
first image is not limited to this. For example, it is possible to
perform controlling so that, in operations for the second time and
thereafter, only the same print mode as the print mode used for the
first image is used for the rest of the images, regardless of
whether the color copy button is operated or the monochrome button
86 is operated.
[0294] The printing apparatus (the SPC multifunction apparatus) of
the above-described embodiments is a printing apparatus capable of
laying out a plurality of images on one medium (also referred to as
a print-recording medium) and printing them, and includes print
mode selecting means for selecting a print mode of either a color
mode or a monochrome mode, image reading means for reading an image
from an original according to the selected print mode, image
obtaining means for obtaining a plurality of images by making the
image reading means perform its reading operation for a plurality
of number of times, image data generating means for laying out the
obtained plurality of images on one print-recording medium and
generating print image data according to the selected print mode,
printing means for printing the generated print image data on the
print-recording medium, and print mode setting means for applying
the print mode initially selected through the print mode selecting
means to all of the plurality of images that have been read by the
image reading means.
[0295] Print paper, for example, may be exemplified as the
print-recording medium, but the material therefor does not matter.
The printing apparatus of the present embodiment reads an image in
an original using the image reading means, lays out the plurality
of images obtained by a plurality of times of reading operations on
one print-recording medium, and prints them. The print mode setting
means applies the initially selected print mode for the series of
processes for laying out and printing the plurality of images on
one print-recording medium, that is, for all of the plurality of
images printed together on one print-recording medium. Therefore,
the user can make the image reading means read in the plurality of
images, while changing originals, according to the print mode that
he/she initially selected, and can obtain a printed object in which
the plurality of images have been laid out on one print-recording
medium. It should be noted that, for example, printed pamphlets,
photographs, and so forth, can be exemplified as the originals from
which images are read.
[0296] Further, particularly, the present embodiment is useful in
cases where original supplying means for automatically supplying
originals to the image reading means is not provided. That is, if
the printing apparatus of the present invention does not comprise
original supplying means for automatically supplying to the image
reading means the originals on which images, which are to be read
by the image reading means, are printed, the user has to change the
originals manually and instruct image reading operations for a
plurality of number of times in such a printing apparatus.
According to the printing apparatus of the present embodiment,
however, since the print mode initially selected by the user is
used for all of the images, the user does not have to set the print
mode every time he/she changes originals.
[0297] In the present embodiment, the print mode selecting means is
configured comprising two selecting means--the color mode selecting
means for executing printing in the color mode and the monochrome
mode selecting means for executing printing in the above-mentioned
monochrome mode--and includes mode selection controlling means for
allowing only the print mode set by the print mode setting means to
be selected when images are read for the second time and thereafter
with the image reading means.
[0298] If the user wishes to print in the color mode, he/she
instructs execution of printing through the color mode selecting
means. If the user wishes to print in the monochrome mode, he/she
instructs execution of printing through the monochrome mode
selecting means. According to the print-execution instruction
through either the color mode selecting means or the monochrome
mode selecting means, the images in the originals are read by the
image reading means, laid out on one print-recording medium, and
printed. In this case, the print mode setting means regards as
valid only the selection of the mode selecting means, among the
above-mentioned mode selecting means, corresponding to the print
mode initially selected by the user, and regards the selection of
the other mode selecting means as invalid. Therefore, even if the
user inadvertently operates the invalidated mode selecting means,
it is possible to ignore such execution instructions due to
misoperation.
[0299] The printing apparatus of the present embodiment comprises
error notification means that provides notification of an error if
a print mode different from the initially selected print mode is
selected through the print mode selecting means when the images are
read with the image reading means for the second time and
thereafter.
[0300] As regards the method for providing notification of an
error, there are methods, for example, of displaying predetermined
warning messages on the display screen or reading out a warning
message with a voice synthesizer. Further, it is also possible to
notify the user of an error, for example, by lighting up a warning
lamp or sounding a warning buzzer. Through this error notification,
it is possible to call the user's attention.
[0301] The printing apparatus of the present embodiment comprises
guiding means for providing guidance about the print mode that has
been initially selected through the print mode selecting means when
the image reading means reads images for the second time and
thereafter.
[0302] As regards the guiding method, it is possible to exemplify a
method, for example, of notifying to the user a predetermined
message indicating the initially selected print mode through the
display screen, the voice synthesizer, and so forth.
[0303] In the printing apparatus of the present embodiment, before
the image, reading means finishes its reading operation for a
plurality of number of times, the printing means starts printing
the image that has already been read.
[0304] That is, printing is started successively from the images
that have been read by the image reading means, instead of starting
printing after obtaining all of the plurality of images that are to
be gathered in one print-recording medium. More specifically, for
example, if the printing apparatus comprises serial-type or
line-type printing means that starts printing
character-by-character or line-by-line, the printing apparatus can
start printing when print image data that allows printing to be
started is obtained (for example, when print image data for one
line or one band has been generated), without waiting for the other
images to be read. In this way, it is possible to shorten the time
until printing is started and to obtain the printed object
promptly. Further, the user can confirm the initially selected
print mode based on the print results on the print-recording medium
that have been printed and output at a prior timing. Therefore,
according to the structure in which printing is started before
finishing the plurality of times of image reading operations, it is
possible to use the print-recording medium as means for confirming
the print mode.
[0305] A printing apparatus according to another aspect of the
present embodiment comprises selecting means for selecting
plural-image printing in which the obtained plurality of images are
reduced in size and laid out and printed on one print-recording
medium according to a predetermined layout, color-print execution
instructing means for causing printing to be executed according to
the color mode, monochrome-print execution instructing means that
is provided independent of the color-print execution instructing
means and that is for causing printing to be executed according to
the monochrome mode, image reading means for reading an image from
an original according to an execution instruction from either one
of the color-print execution instructing means or the
monochrome-print execution instructing means, print mode storing
means for storing the print mode that was applied to the reading
operation by the image reading means, image obtaining means for
obtaining a plurality of images by making the image reading means
perform its reading operation for a plurality of number of times in
case plural-image printing has been selected, image data generating
means for laying out the obtained plurality of images on one
print-recording medium and generating print image data according to
the stored print mode, printing means for printing the generated
print image data on the print-recording medium, and print mode
setting means for applying, to the reading operations for the
second time and thereafter, the print mode stored in the print mode
storing means when the image reading means executed its first
reading operation.
[0306] A printing method according to another aspect of the present
embodiment is a printing method for laying out a plurality of
images on one print-recording medium and printing them using a
printing apparatus that includes image reading means and printing
means, comprising a step of selecting one print mode of either a
color mode or a monochrome mode by using either one of color-print
execution instructing means or monochrome-print execution
instructing means that are provided separately, a step of reading
an image in an original with the image reading means according to
the selected print mode, a step of storing, in print mode storing
means, the print mode selected for the reading operation by the
image reading means for the first image, a step of obtaining a
plurality of images by performing a plurality of times of reading
operations applying the stored print mode to the reading operations
by the image reading means for the second time and thereafter, a
step of laying out the obtained plurality of images on one
print-recording medium and generating print image data according to
the stored print mode, and a step of printing the generated print
image data on the print-recording medium with the printing
means.
[0307] A computer program according to a further aspect of the
present embodiment is a computer program for causing a computer
that includes image reading means and printing means to execute a
method for laying out a plurality of images on one print-recording
medium and printing them, the program causing the computer to
execute the following: a step of selecting one print mode of either
a color mode or a monochrome mode, a step of reading an image in an
original with the image reading means according to the selected
print mode, a step of storing the print mode selected for the
reading operation by the image reading means for the first image, a
step of obtaining a plurality of images by performing a plurality
of times of reading operations applying the stored print mode to
the reading operations by the image reading means for the second
time and thereafter, a step of laying out the obtained plurality of
images on one print-recording medium and generating print image
data according to the stored print mode, and a step of printing the
generated print image data on the print-recording medium with the
printing means.
