Description
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority under 35 U.S.C. .sctn.119 to
Japanese patent application No. JPAP11-086099 filed on Mar. 29,
1999, the entire contents of which are hereby incorporated by
reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a portable electronic
terminal apparatus, and more particularly to a portable electronic
terminal apparatus which includes a flip panel and a plurality of
displays.
2. Discussion of the Background
Recently, the amount of information for electronic apparatuses to
exchange has greatly been increased through data communications
verification because of rapid proliferation of portable
communications equipment and an establishment of the corresponding
infrastructure. In such a circumstance, portability as well as data
communications capability has become more important, especially in
a portable electronic apparatus (e.g., a cellular mobile phone, a
personal assistant device, and the like).
In general, it is difficult to obtain both portability and
visibility at the same time in a portable electronic apparatus.
Such an apparatus needs to be lighter and smaller for increased
portability. For instance, the area reserved for the display of a
portable electronic apparatus can be reduced to increase
portability. Typically, a portable electronic apparatus has a
single display on which various kinds of information are
selectively shown as user instructions; such as a screen scroll
function, a function for switching over to another function, and so
forth. In such a portable electronic apparatus, the user is usually
required to perform complex manipulation of the display to finally
read incoming mail and/or information received from information
service providers.
As one example of the portable electronic apparatus, a mobile
cellar phone, as illustrated in FIG. 1, is provided to overcome the
above-mentioned problem. The mobile cellar phone of FIG. 1 includes
a main body 51, a display 51, an antenna 52, and a loudspeaker 53.
In this mobile cellar phone, a mechanical key pad is not used,
instead a touch-sensitive display is employed so as to fit in a
relatively small area. Since the touch-sensitive display does not
provide a tactile "click" response, the user is required to keep
watching the display to make sure the input is entered properly.
Therefore, the operability of the mobile cellar phone of FIG. 1 is
reduced.
SUMMARY OF THE INVENTION
The present invention provides a novel portable electronic terminal
apparatus which includes a main body, an information input
mechanism, a plurality of displays, a communications mechanism, and
a flip panel. The main body has a hollow section. The information
input mechanism enables input of information, including data and
instructions. A plurality of displays display the information input
through the input mechanism. The communications mechanism transmits
and receives the input information. The flip panel is movably
mounted on the main body and is configured to rotate to open and
close about a side edge portion of the flip panel. This flip panel
is retracted in the hollow section of the main body when closed. In
addition, one of the plurality of displays is mounted on the side
of the flip panel that is exposed when closed.
One of the plurality of the displays may be mounted on a surface of
the hollow section of the main body.
Another display may be mounted on another side of the flip
panel.
One of the displays operates when the flip panel is closed, and the
other display operates when the flip panel is opened.
Each of the displays may be a polymer-film liquid crystal
display.
The displays may selectively be used by a user instruction input
through the information input mechanism.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In describing preferred embodiments of the present invention
illustrated in the drawings, specific terminology is employed for
the sake of clarity. However, the present invention is not intended
to be limited to the specific terminology so selected and it is to
be understood that each specific element includes all technical
equivalents which operate in a similar manner.
Referring now to the drawings, wherein like reference numerals
designate identical or corresponding parts throughout the several
views, and more particularly to FIG. 2 thereof, there is
illustrated a portable electronic terminal apparatus 100 according
to an exemplary embodiment of the present invention. The portable
electronic terminal apparatus 100 includes a main body 1, an
antenna 2, a loudspeaker 3, a flip panel 4, a first display 5, a
data entry panel 6, a microphone 7, and a button 8.
In this exemplary embodiment, the main body 1 has a front surface
divided into upper, middle, and lower regions to which the
loudspeaker 3, the flip panel 4, and the data entry panel 6 are
provided, respectively. The antenna 2 is mounted inside the main
body 1 so as to protrude from the top surface of the main body 1.
The microphone 7 is mounted on a portion of the lower region closer
to the bottom surface of the main body 1, and the button 8 is
provided to a side surface of the main body 1 near the upper
region. The flip panel 4 has a left side edge portion which is
movably mounted in the left side edge of the middle region of the
main body 1 so that the flip panel 4 can rotate to open and close
about the left side edge portion. The first display 5 is mounted on
the front surface of the flip panel 4. The data entry panel 6
includes a ten-key pad, for example, and other instruction keys. In
addition, the portable electronic terminal apparatus 100 further
includes an open button 9 for opening the flip panel 4. The open
button 9 is mounted on a side surface of the main body 1 close to
the flip panel 4, as illustrated in FIG. 3.
When the open button 9 is pressed, the flip panel 4 is opened, as
illustrated in FIG. 4. As illustrated in FIG. 4, the portable
electronic terminal apparatus 100 further includes a second display
10, a third display 11, a hook 12, and a dent 13. A hollow section
14 is created when the flip panel 4 is opened. The second display
10 is mounted on a rear side of the flip panel 4. The second
display 10 may be integral with the first display 5. The third
display 11 is mounted on a portion of the main body 1 opposite to
the second display 10 with the flip panel 4 closed so as to appear
next to the second display 10 with the flip panel 4 opened. The
hook 12 is provided to a side edge of the rear surface of the flip
panel 4 so as to hook up to the main body 1 with the dent 13
mounted on the main body 1. The hollow 14 is to receive the flip
panel 4 when it is closed. For the open/close mechanism of the flip
panel 4, the portable electronic terminal apparatus 100 is further
provided with a hook receiver (not shown) and a spring (not shown).
The hook receiver is mounted on a portion of the main body 1 closer
to the dent 13 and is engaged with the hook 12 when the flip panel
4 is closed. The spring is mounted on a portion of the left side
edge of the flip panel 4 so as to provide a tension to the flip
panel 4 to open. The above-mentioned hook receiver is associated
with the movement of the open button 9 so that the flip panel 4 is
opened, as illustrated in FIG. 4, with the tension of the spring
when the open button is pressed and is closed, as illustrated in
FIG. 2, when the user closes the flip panel 4.
Each of the first and second displays 5 and 10 may be a thinner
display (i.e., a polymer-film liquid crystal display) so that the
flip panel 4 can be made thinner.
Referring to FIG. 5, an exemplary structure of a display when the
first and second a displays 5 and 10 are united in one piece is
explained. In FIG. 5, an exemplary structure of a display includes
a reflection plate 20, first polarizing plates 21 and 22, first
transparent electrodes 23 and 24, liquid crystal layers 25 and 26,
second transparent electrodes 27 and 28, phase plates 29 and 30,
second polarizing plates 31 and 32. That is, the first display 5
includes the first polarizing plate 21, the first transparent
electrode 23, the liquid crystal layer 25, the second transparent
electrode 27, the phase plate 29, and the second polarizing plate
31. Further, the second display 10 includes the first polarizing
plate 22, the first transparent electrode 24, the liquid crystal
layer 26, the second transparent electrode 28, the phase plate 30,
and the second polarizing plate 32. The first display 5 is mounted
on a front surface of and the second display 10 is mounted on a
rear surface of the reflection plate 20 so that a double-sided
display is configured with the flip panel 4.
When the flip panel 4 is closed, the first display 5 is supplied
with power but the second and third displays 10 and 11 are not
supplied with power. That is, the second and third displays 10 and
11 can only be supplied with power when the flip panel 4 is opened.
In addition, the user can set a condition in which the second and
third displays 10 and 11 are not supplied with power through the
data entry panel 6. Accordingly, the second and third displays 10
and 11 will not be supplied with power even when the flip panel 4
is accidentally opened. As a result, it becomes possible to avoid
an increase of a power consumption by an accidental opening of the
flip panel 4.
Referring to FIGS. 6 and 7, an exemplary way of using the portable
electronic terminal apparatus 100 will be explained. When the
portable electronic terminal apparatus 100 is not used, it stays in
an idle status, as illustrated in FIG. 6. In the idle status, the
flip panel 4 is closed and the first display 5 displays minimum
information on it. The minimum information may include strength of
the electric field (i.e., signal strength), the time of day, date,
incoming mails, and so forth.
To read incoming mails, the user opens the flip panel 4 so that the
second and third displays 10 and 11 show up, as illustrated in FIG.
7. In this case, the second display 10 shows a list of incoming
mails and the third display 11 shows the contents of a selected
incoming mail.
With the above-described structure, the portable electronic
terminal apparatus 100 can conveniently display multiple pages of
information. Moreover, it obviates the necessity for the user to
enter the complex instructions through the data entry panel 6 to
read incoming mails. Thus, the user can read incoming mails in much
the similar way to read a book by turning pages.
Next, a first modification made to the portable electronic terminal
apparatus 100 is explained with reference to FIGS. 8 and 9. In FIG.
8, a first modified portable electronic terminal apparatus 200 is
shown. The first modified portable electronic terminal apparatus
200 of FIG. 8 is similar to the portable electronic terminal
apparatus 100, except for a flip panel 204 and a knob 215.
The flip panel 204 of FIG. 8 is configured to have a top edge
portion which is mounted on the top edge of the middle region of
the main body 1. That is, the flip panel 204 can rotate about the
top edge portion to open and close while the flip panel 4 of FIG. 2
rotates about the left side edge portion. The knob 215 is engaged
with a bottom portion of the flip panel 204 when the flip panel 204
is closed and the flip panel 204 is retracted in the main body 1,
as illustrated in FIG. 8. To open the flip panel 204, the user
needs to push or slide the knob 215 to release its engagement with
the bottom portion of the flip panel 204. Consequently, the flip
panel 204 is opened towards the side of the loudspeaker 3, as
illustrated in FIG. 9. Because of this direction of opening, the
flip panel 204 is kept out of the way of the user's hand holding
the main body 1.
Next, a second modification made to the portable electronic
terminal apparatus 100 is explained with reference to FIGS. 10 and
11. In FIG. 10, a second modified portable electronic terminal
apparatus 300 is shown. The second modified portable electronic
terminal apparatus 300 of FIG. 10 is similar to the portable
electronic terminal apparatus 100 of FIG. 2, except for a fixed
display panel 316 and a flip panel 317. The fixed display panel 316
is fixed on the middle region of the main body 1. The flip panel
317 includes a secondary display 318, as illustrated in FIG. 11.
The flip panel 317 is configured to have a bottom edge portion
which is mounted on the bottom of the lower region of the main body
1. That is, the flip panel 317 can rotate about the bottom edge
portion to open and close while the flip panel 4 of FIG. 2 rotates
about the left side edge portion. With this configuration, the data
entry panel 6 can be protected by the flip panel 317 when it is
closed and both of the data entry panel 6 and the secondary display
318 will show up when the flip panel 317 is opened. Thus, the
display size can be extended without increasing the size of the
terminal apparatus.
Numerous additional modifications and variations of the present
invention are possible in the light of the above teachings. It is
therefore to be understood that within the scope of the appended
claims, the present invention may be practiced otherwise than as
specifically described herein.
