DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0041] Referring to FIGS. 1 through 25, several preferred
embodiments of the present invention will be described. The present
invention is directed to stand-alone, computer peripheral scanners
which, in their conventional form, include a connection to and
requirement that they be operatively connected to a computer for
processing digital signals sent by either the charged couple device
("CCD") or a contact image sensor ("CIS") incorporated within the
scanner. The digital signals are then processed in the computer,
and stored in a conventional storage media, such as a removable
hard drive, 3.5 inch floppy disk, Zip-Drive.RTM. or the equivalent.
The present invention is directed to incorporation of removable, or
portable data storage media, i.e., memory, within the scanner
itself. The present invention, therefore, enables the user to scan
an image with, and store the digital data representation of the
image in, a portable memory in the scanner itself, and eliminates
the need for having a computer operatively connected thereto during
the scanning process. The scanned image may then be stored on the
portable memory, such as a 3.5 inch floppy disk, for example. The
disk then may be removed from the scanner upon completion of
scanning, and may be taken to a remote computer for further
processing.
[0042] Referring to FIG. 1, a first preferred embodiment of the
present invention is shown, including a conventional CCD-type
flatbed scanner 20, housing 22, glass platen 24 and hinged lid 26.
Also shown at 28 is a disk drive into which a conventional 3.5 inch
floppy diskette 30 may be inserted for storage of digital data
generated during the scanning process. Also shown on the scanner
housing is control panel 32, which will be described in greater
detail in conjunction with FIGS. 3 and 4.
[0043] Referring to FIG. 2, a second preferred embodiment of the
invention is shown adapted for use in a CIS-type scanner 34. The
scanner 34 includes a housing 36, glass platen 38, hinged cover 42,
and a CIS scanner positioned on a carriage 40. A CIS scanner of
this type is described in commonly owned U.S. Pat. No. 5,907,413,
incorporated by reference as if set forth fully herein. Housing 36
also incorporates a conventional disk drive, such as a disk drive
44 for a conventional 3.5 inch floppy disk 46.
[0044] Referring to FIG. 3, a third preferred embodiment is shown,
including a conventional transmissive/reflective type scanner 50, a
housing 52, reflective scanning platen 56 and a transparency holder
54. This type of transmissive/reflective scanner is of the type
disclosed in commonly owned U.S. Pat. No. 5,705,805, entitled
Transmissive/Reflective Optical Scanning Apparatus; commonly owned
U.S. Pat. No. 5,814,809 entitled Transmissive/Reflective Optical
Scanning Apparatus and in commonly owned U.S. Pat. No. 5,574,274.
Referring to FIG. 3, scanner 50 also incorporates a conventional
disk drive into which a removable conventional, preferably,
formatted, 3.5 inch floppy diskette 58 may be used for purposes of
the present invention. The housing 52 includes a control panel 60
which includes a liquid crystal display ("LCD") and a
multi-function control button 64.
[0045] Referring to FIG. 4, an alternate control panel 66 is shown
having LCD display 68 and a plurality of control buttons. Control
button 70 controls the mode of operation, either color, or black
and white, with the light emitting diode ("LED") 72, when energized
indicating the color mode of operation. The black and white mode of
operation is indicated when LED 74 energized. Control button 78
controls the resolution of the scanner, with a high, low and medium
resolutions preferred. LED's 80, 82 and 84 indicate whether the
selected resolution is high, low or medium, respectively. Control
button 86 is for controlling whether the LCD display is "on" or
"off", the "on" being indicated simply by having an image on the
display 68, and "off" being indicated by an absence of a display.
Control button 88 is the erase control button, in which case an
image stored in the disk drive may be erased. Control button 76
controls advance of the image displayed to the next image stored in
the media. Button 90 controls the data compression of raw data.
[0046] Alternatively, and as shown in FIG. 3, the alternate control
panel 60, control panel includes a multi-function control button 64
with "left", "right", "up", "down", and "enter" control functions,
as is conventional. With such a multi-function control button 64,
the various operational control choices are displayed as a series
of menus on the LCD 62, with a cursor or pointer being controlled
by operator movement of the multi-function button.
[0047] Referring to FIGS. 1 through 4 above, the present invention
scanner provides for either reflective or transmissive scanning,
and flatbed or handheld scanning, as is conventional and, at
various resolutions, as also is conventional. However, the present
invention also provides for transfer of the digital data
representative of each scanned image directly to a portable memory
positioned in the scanner itself. Alternatively, of course, an
alternate transfer path may be incorporated into the scanner
whereby digital data may be transferred directly to a computer, as
is found in conventional scanners of this type.
[0048] Preferably the portable memory incorporated into a scanner
of the present invention is a 3.5 inch floppy diskette, as is well
known. Also, the present invention may be used in conjunction with
other types of conventional data storage media, such as a flash
memory card (also known as a PCMCIA card); a 100 MB Zip-Drive; a
120 MB, 3.5-inch diskette using a 120 MB, 3.5-inch disk drive
available from O.R. Technology, Campbell, Calif., as its model
FD-3120A (drive has industry standard ATAPI IDE interface); and
also may be adapted to use a compact disk (CD) with write
capability. The conventional 3.5 inch floppy diskette holds
approximately 1.44 megabytes of data, which is equivalent to
approximately 30 to 40 images, after compression, for a standard
resolution, color VGA, 640.times.480 pixel image.
[0049] With respect to a standard or normal resolution for flatbed
scanners of the general type described herein, a 300 dots per inch
("dpi") resolution is typical. At this resolution, using a color
mode of operation, it is expected that a conventional 3.5 inch
floppy diskette would store approximately 10 to 12 images wherein
the object is of a standard letter size, i.e., 81/2.times.11
inches, with presently available data compression technology.
[0050] Also, as will be appreciated, incorporation of a portable
storage media such as a floppy diskette, etc., will require
adaptations to the scanner such as provision for a battery and AC
power supply to the memory device. With respect to the different
types of portable storage media, a 3.5 inch floppy disk is most
preferred, with a Zip-Drive, holding approximately 100 megabytes of
data, being also preferred.
[0051] Referring to FIG. 5, a flow chart of programming steps for
controlling the data collection, display and storage features of
the invention will be described. Each of the blocks in the block
diagram represent a programming step, or a series of programming
steps which are available as conventional software, and/or readily
generated using conventional programming techniques. Control
routine 92 begins by starting the function at step 94 at the
conventional on/off power button, not illustrated in FIG. 4. Once
the system is energized, the mode of operation is selected at step
96, being either a color or black and white mode of operation. As
shown in FIG. 4, control step 96 is selected with button 70, and
LED 72 indicating a color mode of operation and LED 74 indicating a
black and white mode of operation. Once the mode of operation is
selected, the degree of resolution is selected, at step 98.
Corresponding control button 78, with high 80, medium 82 and low 84
resolution LEDs also shown on the front of the control panel in
FIG. 4. With conventional scanners, the medium resolution is
typically 300 dpi, a high resolution is typically 600 dpi, with as
high as 1200 dpi. For scanner operation, a low resolution is
typically approximately 100 dpi.
[0052] Once the resolution has been selected, the scanning function
is begun, at step 100, during which the carriage is advanced across
the length dimension of the scanner to scan the object image and,
through a CCD or CIS camera the object image is converted into
digital data representative of the object image. Referring to FIG.
4, the scan or advance control button is shown at 76. Once the data
has been scanned, data may be compressed, in step 102, using a
conventional data compression routine, such as JPEG, or the
equivalent. It is within the scope of the present invention that a
single, predetermined data compression routine may be incorporated
into the computer software application program controlling the
operation of the scanner, or that several data compression options
may be available, with further control options made available at
the control panel (not shown) for selecting a particular data
compression technique. Once the data has been compressed, it is
then stored on the removable digital data storage medium, step 104
indicating being stored on disk. Alternatively, no data compression
is also an option, step 103. Data Compression is controlled by
button 90, as shown on FIG. 4. Once the data has been stored on the
disk, it may also be displayed on the LCD display, step 106,
corresponding to display 62 (FIG. 3) or display 68 shown at FIG. 4.
The stored data may be erased as described above in conjunction
with control button 88.
[0053] Referring to FIGS. 6-12, a fourth preferred embodiment 200
of the present invention is a conventional flat bed scanner that
incorporates a personal computer (PC) central processing unit (CPU)
underneath the scanner platen and adapted to control conventional
scanning, editing, input and output functions. The PC CPU is not
shown in FIGS. 6-12, but can be conveniently positioned within the
housing of the scanner, preferably underneath the platen of the
scanner. The scanner 200 includes a top cover 202 and a housing
204. The front of the scanner includes a control panel 206 which is
preferably flush with the level of the scanner which includes the
platen. The shape, style and overall external configuration of the
scanner may take many forms, one preferable form of which is
illustrated in FIGS. 6-12. FIG. 7 illustrates the scanner as seen
from a bottom, perspective view, showing the scanner bottom surface
208 and the front side of the housing 204 from a different
perspective than that shown in FIG. 6. Referring to FIG. 8, the
scanner 200 is shown with its cover 202 in a partially raised
position, exposing a recess 210 that is configured and adapted for
use as a handle to raise and lower the cover. The top surface of
the scanner housing includes a scanning bed 212 having a
conventional glass platen. The front of the scanner includes a
conventional 3.5'' floppy disk drive 214 and a conventional 100 MB
drive, commonly referred to as a "Zip.RTM." brand drive. Both of
these drives are operatively connected to the CPU in a conventional
fashion.
[0054] Referring to FIG. 9, this preferred embodiment also,
preferably includes a conventional share port 218, a conventional
printer point 220 and a conventional accessory port 222 for use,
optionally, for peripherals such as a document feeder. FIG. 10 is a
view of the opposite side 224 of the side illustrated in FIG.
9.
[0055] With reference to FIG. 12, the control panel 206 includes
controls and indicators for numerous functions used during
operation of the scanner. Start button 226 initiates the selected
operation, such as scan, or copy, both of which are conventional
functions in scanners, as is well known. Stop/clear button 228
controls and permits the current scanner function to be stopped
during operation. This function is used for printer set up
operations and to return any settings back to default values. Also,
pressing and holding the stop/clear button 228, preferably for 5
seconds, will reset a conventional file name counter. Mode button
230 functions to toggle between copying images to a connected
printer, which may be either black and white or color, and scanning
to a floppy or Zip.RTM. disk, which may be black and white, gray
scale or color. The desired operation is selected, preferably, by
pressing the mode button repeatedly to cycle through the various
options. Compression button 232 functions to choose the amount of
file compression desired for the scanned image. The options
included, preferably, are low, medium and high compression.
Conventional compression techniques are used in the present
invention. As is well known, lower compression results in a larger
file size but provides better image quality. In the preferred
embodiment, compression setting is not available for the copy
function or when scanning in a black and white mode. The control
panel also includes the +/-button 234, with the - function
illustrated at 236 and the + function illustrated at 238. These
buttons function to specify the number of pages to be printed, when
the scanner is in the copy mode of operation. When the scanner is
in scan mode, these buttons function to increase or decrease the
resolution level. Also, when the mode button 230 is pressed and
held for at least 5 seconds, preferably, and with the printer mode
selection selected, the +/-buttons 234, 236 and 238 function to
choose a printer mode number that corresponds to a printer model.
Various printer models are supported, as desired, with the present
invention.
[0056] Resolution control button 240 functions to choose the level
of detail desired for a particular image to be scanned. The
resolution is increased by using the + button 238 and decreased by
pressing the - button 236. The preferred resolution settings for
the scan function, in dots per inch, for the default settings for
low, medium and high resolution are as follows: [0057] In black and
white mode: 150, 300 and 600 [0058] In gray scale: 75, 150 and 300.
[0059] In color: 75, 150 and 300.
[0060] In the copy function the resolution settings, in dots per
inch, the default settings for low, medium and high resolution are
as follows: [0061] In black and white: 300, 450 and 600. [0062] In
color mode: 100, 150 and 300.
[0063] In this preferred embodiment of the present invention, the
settings shown on the LED display panel during the copy mode refer
not to the resolution setting itself but rather to the number of
copies to be printed. Also, during operation, copying photographs
or documents in medium or high resolution modes may require use of
a Zip.RTM. drive for temporary storage. In this case, if the
indicator light next to the Zip.RTM. icon flashes either an
IBM-compatible, formatted Zip.RTM. disk must be used or a lower
resolution must be selected.
[0064] Scan area selection button 242 functions to choose the
maximum size that can be scanned by the scanner. In the present
invention, the preferred sizes are A4, which is 8.5'' by 11.7'';
and letter, which 8.5'' by 11'' and "auto". Auto refers to
enablement of an automatic edge detection system, which is
conventional. In this mode, the scanner will complete an initial
pass to find the edges of the photo or document and then scan only
the detected area. When using this mode, it is preferable to keep
the lid closed.
[0065] The document function button 244 functions to automatically
set preferred defaults for quickly scanning a text document. In the
present invention, the preferred default settings are B/W for the
scan mode. Although in this mode color documents may be scanned,
the resulting output would be black and white. The default
resolution is 300 dpi, the scan area is letter size and no
compression is performed. After the document button is pressed to
select the default settings, individual settings may be altered as
desired, and then scanning may be started by pressing the start
button 226.
[0066] The "save to" button 246 functions to select whether the
scanned images and saved to a Zip.RTM. disk or to a floppy disk. In
the present invention, it is preferred that pressing and holding
the Asave to@ button for at least 5 seconds will cause the CPU to
attempt to format the floppy disk into an IBM-compatible formatted
disk. This function will erase all files on the disk unless it is
write protected. Various file formats may be used, but in the
present invention the PCX file format is preferred for files
scanned in black and white mode, and Jpeg file format is preferred
for files scanned in the color mode.
[0067] Also, preferably, saved files are assigned numeric file
names in sequence, starting from img01.pcx or img01.jpg, repeating
after img99. Preferably, the counter may be reset back to img01 by
pressing and holding the stop/clear button 228 for at least 5
seconds. In this case the LED display will show "F1" to indicate
that the counter has been reset to indicate file number "1".
[0068] Although the present invention could use an internal clock,
the preferred embodiment does not and all saved files are date
stamped as Jan. 1, 1999.
[0069] Various indicator lights and labels may also be used on the
control panel 206. For example, in the preferred embodiment,
indicator lights 248 and 250 indicate B/W and Color, respectively
in the copy mode. Indicator lights 252, 254 and 256 indicate B/W,
Gray and Color, respectively in the scan mode. Indicator lights
258, 260 and 262 indicate high compression, medium compression and
low compression, respectively.
[0070] Above the LED 263 display, indicator lights 264, 266 and 268
indicate an unformatted disk, a full disk and no disk,
respectively. Above, the resolution button 240, indicator lights
270, 272 and 274 indicate high resolution, medium resolution and
low resolution, respectively. Above the scan area control button
242, indicator lights 276, 278 and 280 indicate A4, letter and auto
sizes respectively. Above the Asave to@ control button 246 the
indicator lights 282 and 284 indicate selection of the Zip.RTM.
drive or diskette, respectively.
[0071] With reference to FIG. 11, the back 286 is illustrated with
a recessed power plug 288 shown.
[0072] This fourth preferred embodiment of the present invention is
a 36-bit, stand-alone scanning appliance with scan, copy,
image-saving, image-compression and disk-formatting capabilities
combined into a single scanner. This preferred embodiment is a
stand-alone scanner which means that there is no need to connect
the scanner to a computer. Rather, once power is supplied to the
scanner, it is ready to scan and copy, save and perform its other
functions. Because it is a stand alone scanning device, it comes
with its own file saving features built in. The Iomega brand
Zip.RTM. drive accommodates a standard 100-MB, IBM-compatible,
formatted Iomega Zip.RTM. disk and also includes a standard floppy
drive that accommodates conventional 3.5'' floppy disks. This
preferred embodiment includes 600.times.600 dpi optical resolution
and scans in color, gray scale and black and white modes. Also,
preferably, it is adapted for and may include conventional image
editing, document management, and OCR software for scanning photos
and documents, thus making the entire scanning process simple and
convenient.
[0073] Typical optional uses for the present invention would
include the scanner to scan images and then send the scanned images
to a printer. In this configuration, a standard printer cable from
the printer's parallel port is preferably connected to the present
invention's printer port 220. Then, the "mode" control button 252
is held for at least 5 seconds, and the +/-keys are operated to
choose the printer mode number corresponding to the printer model
that is connected. The start button is then pressed to save the
printer mode number into the computer's CPU memory and set up is
complete.
[0074] In an alternate mode of operation, the same printer may be
shared with a PC and the scanner of the present invention. In this
application two standard parallel printer cables are used, with one
cable connected from the printer to the printer port 220 and the
second printer cable connected from the PC's parallel port to the
"share port" 218. During operation in this mode, the scanner of the
present invention must be turned "on".
[0075] In yet another mode of operation, the scanner of the present
invention may be configured to work with Microtek brand, standard
10-page auto document feeder, such as model ADF-600L, for
simplified multi-page document scanning. In this mode of operation,
the upper lid 210 is removed by raising it up 90.degree. and
lifting it straight up. Then the metal posts of the ADF are
inserted into the holes on the right side of the scanning bed,
shown at 288 and 290 in FIG. 8. The ADF is then plugged into the
accessory port 222 in the scanner, and is ready for automatic
document feed mode.
[0076] The present invention also includes numerous conventional
warning indicators that are displayed on the LED display panel.
Detection processing and display of these indicators are
conventional, and may include messages such as "write-protected
disk", "no-disk", "disk full", "disk not formatted", "warm up" and
so forth, as is conventional.
[0077] Described below are several operations of the present
invention.
