Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus using a flat display device such as a flat display, and more particularly to an information processing apparatus using a plurality of flat displays in a notebook manner.

[0002]

2. Description of the Related Art A liquid crystal element and a coordinate input device are integrated,
As a conventional example of a paper-like information processing apparatus, Japanese Patent Laid-Open No.
60-75980, JP-A-3-214309, UK patent publication
GB2193827A, disclosed in US Pat. No. 4,730,186. Further, as a conventional example in which the coordinates of the liquid crystal element and the coordinate input device are matched, there is one disclosed in JP-A-59-183428 (US Pat. No. 4,646,073).

Further, as a conventional example of an information processing apparatus using a plurality of displays, Japanese Patent Laid-Open Nos. 2-127714 and 4-15 are cited.
As disclosed in Japanese Patent Laid-Open No. 717 and Japanese Patent Laid-Open No. 4-15725, a touch screen is attached to each of the two screens, information is input and output on the two screens, and man-machine characteristics are improved. As shown in Japanese Patent Laid-Open No. 4-278658, there is one in which a plurality of liquid crystal display elements capable of double-sided display are overlaid and integrated so that pages can be turned over and the entire information can be grasped with the same feeling as a book. .

[0004]

The above-mentioned prior art considers the display of one screen or two screens and the integration of the input display of the coordinate input device, but it has a plurality of displays of three screens (including double-sided display) or more. Regarding the integration of the input display of the coordinate input device, there are problems in cost reduction and thinning, and also in usability such as page turning. That is, when the sensor of the coordinate input device and the sensor of the liquid crystal are provided integrally for each page and formed into a sheet, the sheet becomes thicker, which makes it difficult to turn the page thicker and the number of steps increases, and the cost increases. Was there.

Since the number of pages of the display screen was small, the display screen was displayed as a multi-window, and the display method was to simply refer to the display contents like a book or select a menu or icon. The only way to start the required application software was. That is, sufficient consideration has not been given to an effective usage method due to the presence of a display of a plurality of pages. For example, when sending and receiving mails and the schedule screen are displayed on the page only by opening a certain page, the operation to open a certain page is returned to the previously entered word processing edit screen. Was not done. On the contrary, when the operation of folding the cover is performed, it is not taken into consideration that the programs saved up to now and the power is automatically turned off are not taken into consideration. Man-machine property was bad such as performing procedures.

Further, although it has been shown in the conventional example that double-sided display is performed to display a large amount of information, a specific double-sided display structure and a color sheet structure have not been disclosed.

Further, in order to take in the already printed paper information, it has to be performed from an external scanner device through an interface. If a scanner is built in the information processing device itself, the device itself becomes large because of the mechanical structure, and there is a problem in portability.

Therefore, the present invention solves such a technical problem, and an object of the present invention is to provide a convenient notebook type information processing apparatus using a plurality of displays.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a sheet type flat display in a notebook type information processing apparatus in which a coordinate input device for detecting handwriting input and a plurality of flat displays are integrated. A plurality of pages can be opened and overlapped with each other, and one coordinate input device is provided in common for the plurality of flat displays, and the coordinate input device is provided on the display surface of the flat display of each opened page. On the other hand, coordinates can be input.

Preferably, the coordinate input device also serves as a cover for the plurality of flat displays, and the input surface of the coordinate input device is provided inside the cover.

It is also possible to provide cover opening / closing detecting means for detecting the opening / closing of the covers of the plurality of displays, and turn on / off the power supply of the apparatus according to the detection output of the cover opening / closing detecting means.

A page position detecting means for detecting which page is currently open is provided, a specific application program is associated with a specific page, and when the specific page is opened, it is automatically Alternatively, the application program can be configured to be activated.

In this case, when the page position detecting means detects that the specific page is closed, the execution of the specific application program is interrupted, and the execution state of the program is restarted for the next restart. And a program restoration processing means for restoring the program execution state saved by the program comparing means when it is detected by the page position detecting means that the specific page is opened. Is preferably provided.

Further, the cover is provided with means for generating display instruction information or display information, and means for wirelessly transmitting the display instruction information or display information to at least one of the plurality of plane displays. 1
A unit for wirelessly receiving and displaying the display instruction information or the display information and a built-in battery may be provided on the one flat display so as to be detachable from the cover.

[0015]

According to the present invention, the coordinate input device which is also used as the cover is configured to be shared by a plurality of displays, and the coordinates of the stylus pen of the coordinate input device can be detected through the display. You can enter coordinates even if you repeat the display. Electromagnetic and electrostatic coordinate input devices and the like are well known as those which penetrate a display and detect coordinates. Therefore, by also serving as the coordinate input device, it contributes to thinning and cost reduction of the information processing device. The use of a plastic liquid crystal for a flat display makes it particularly thin, so that you can turn pages like paper and improve operability.

For each page, it is possible to detect which page is open by detecting the coordinates unique to that page. This page position detection means and program save,
By associating it with the returning means, the program running on the page can be restored at the same time when it is opened, and the necessary work can be immediately started. This improves work efficiency.

Further, the opening / closing detection means for detecting the opening / closing of the cover and the power-on / off of the information processing apparatus and the program saving / restoring means are interlocked with each other, so that the power of the information processing apparatus is turned on at the same time when the cover is opened. A predetermined processing program is started, for example, an authentication system is started.

The display sheet enables two-sided display by sticking two flat displays together. However, in the case of liquid crystal, the deflection film alone causes interference with the display content of the liquid crystal on the opposite side. The sheet was inserted into one display sheet. As a result, by eliminating the interference caused by the mutual display, the simultaneous use of the color sheet (paper may be used) makes it possible to distinguish the processing programs by color and improve the intuitiveness.

Further, by mounting the two-dimensional surface sensor type scanner on the notebook type information processing device itself, since there is no mechanical mechanism, the paper information can be easily read at high speed, and it is small and portable. .

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a system configuration and external view of an embodiment of the present invention.

This embodiment will be described on the assumption that it is used in an office environment. That is, various servers SV1 and SV2 are connected to the network NET, and the notebook type information processing devices WKNT1 and WKNT2 of the present invention are positioned as their clients. The network NET is connected via the wireless networks NET1 and NET2 and the wireless terminals WT1 and WT2. Therefore, the operator can freely and effectively use the server resource anywhere in the office and has high portability. Of course, it may be used as a single device without using the network.

Now, the notebook type information processing apparatus WK of the present invention
The NT1 has a plurality of liquid crystal display sheets SHT1, SHT2, SHT3 (three sheets will be described, but there may be more), as shown in the appearance of FIG. LCD of display LCD1, LCD2, LC
D3 and position indicators S1, S2 for page position detection
There is S3.

On the other hand, the liquid crystal display sheet SHT1,
Other than SHT2 and SHT3, the main body of the processing device is mainly the coordinate input device TB (which uses an electromagnetic type in this practical example) that also serves as the cover cover, the stylus pen PEN, and the input devices SRL1 and SRL2 for screen operation (scroll instructions). ), PG
C (for page indication), and a position indicator P for detecting opening / closing of the cover cover.

The notebook type information processing device WKNT1 is WK
Like the NT2, it can be folded in two from the center and has a structure that is easy to carry. Further, since the liquid crystal display sheets SHT1, SHT2 and SHT3 use film-like liquid crystals, pages can be turned like a book. It should be noted that film-like liquid crystals have been easily made possible by recent technology (see, for example, Article 92 of the '92 .12 Nikkei Bytes, page 130).

Next, the operation outline and use outline of one embodiment of the present invention will be described below.

First, when the notebook type information processing device WKNT1 is opened, the opening / closing of the cover is detected using the position indicator P,
A given program (usually a password or ID
The authentication program for inputting the password in PEN) is activated.
After that, the previously processed program is restored on the opened page and the operation is displayed.

If another page turning operation is performed, the page position detecting means detects the coordinate positions of the page position detecting position indicators S1 to S3 to determine which page has been opened or closed. Then, the program save / restore processing is performed corresponding to the page. That is, for the closed page, the program execution is interrupted, the saving process for resuming is executed, and for the opened page, the interrupted program restoration process is executed. As a result, the user can directly enter the necessary work just by performing the operation of opening the page, and the man-machine characteristic can be greatly improved.

When the target page is opened and the pen PEN is operated as in WKNT1 of FIG. 1, the pen PEN signal is
Since the electromagnetic pen is used in this embodiment, the coordinates can be detected by the coordinate input device TB penetrating the liquid crystal display sheet SHT1 and embedded in the cover cover. Depending on the detection of the coordinates, it is possible to specify a menu, an icon, and further handwriting as in the conventional case. Even if there are a plurality of liquid crystal display sheets, the pen PEN signal can penetrate them, so that coordinate detection is possible.
As a result, it is possible to realize a notebook type information processing apparatus that solves the drawbacks of the conventional coordinate input device integrated for each display.

When communicating with the servers (SV1, SV2) connected to the network NET, information can be exchanged via the wireless terminal WT1 using the wireless network NET1. Similarly, it is also possible to perform communication between the notebook type information processing devices.

Next, the structure of one embodiment of the present invention will be described with reference to FIGS.

FIG. 2 is a sectional view of a notebook type information processing device WKNT1 according to an embodiment of the present invention. As described above, the cover cover is composed of the coordinate input device TB, and in particular, both the two-dimensional surface position sensor SC and the sensor of the coordinate input device TB are incorporated together in the upper part. The two-dimensional surface sensor SC is an integrated CCD sensor, light source, and lens. For example, the two-dimensional surface sensor SC faces the liquid crystal display sheet SHT.
The document is sandwiched between 3 and the document to be read. Two-dimensional surface sensor SC
Is at a technically possible level by combining recent liquid crystal technology, CCD technology, and memory technology.

A plurality of liquid crystal display sheets are bundled as shown in the figure, and are bound in advance like a notebook in the main body. As a binding method, a removable binder method, a closed hole method, and a non-removable adhesive fixing method can be considered. Considering the expandability, the removable method is desirable.

The connection between the main body and the liquid crystal display sheet is cordless in this embodiment, as will be described later with reference to FIG. As a cordless method, a method using a radio wave, a method using a light beam such as infrared rays, or an electromagnetic coil method is considered. Any method may be used.

FIG. 3 is a structural diagram of the liquid crystal display sheet SHT1. SHT2 and SHT3 have the same structure. Since the liquid crystal display sheet SHT1 performs double-sided display, it has two liquid crystal displays LCD11 and LCD12.
The opaque color sheet CLR1 is sandwiched between. Usually, the liquid crystal display is displayed by applying a potential to the liquid crystal with a transparent electrode and utilizing the phase difference from the polarizing plate. Therefore, if two liquid crystals are simply overlapped, the influence of the image on the opposite side comes out. Therefore, an opaque sheet CLR for separation
1 is placed between the liquid crystal display sheets.

Further, the liquid crystal display sheet SHT1 is equipped with a position indicator S1 for page position detection, batteries CELL11 and CELL12 for powering the sheet, and a display sheet controller SHTC1. Batteries CELL11 and CELL12 are photocells and 2
It is a combination of the following batteries, and requires enough battery capacity to display the display information. If a wire is used to connect the liquid crystal display sheet SHT1 to the main body, power can be supplied from the main body, so this battery is not necessary.
The display sheet control controller SHTC1 is mounted in the vicinity of the binding margin in terms of page turning easiness and reliability. As a matter of course, the controller SHTC1 is also mounted on a film-shaped sheet as realized by the mounting method of a clock or a calculator.

Next, a block configuration of specific functions of the notebook type information processing device WKNT1 will be described with reference to FIG.

The notebook type information processing device WKNT1 is roughly composed of a main body WKNT and a block of three liquid crystal display sheets SHT1, SHT2 and SHT3. Main body WKNT and 3 liquid crystal display sheets S
Information is exchanged between the HT1, SHT2, and SHT3 via the cordless network N-SHT as described above. Liquid crystal display sheet SHT
1, SHT2 and SHT3 are seat controllers SH
Since TC1 (SHTC2 and SHTC3 are not shown) is mounted, the display information exchange with the main body WKNT is performed by the interface circuits SHT-M I / F and SHT1-S.
This is performed by code data via the I / F.

The main body WKNT is a notebook type information processing device W.
Note controller WKNTC that controls the entire KNT1
And peripherals and sensors. The peripheral devices and sensors include a position indicator P for detecting cover opening / closing (this position does not correspond to FIG. 1 for convenience of illustration), a coordinate input device TB, a stylus pen PEN, a sensor for screen control (SRL1, SRL2, PGC), two-dimensional surface sensor S
There is C. Signals from these peripherals and sensors are sent to each interface (TB I / F, PAGE I / F, SC
It is taken into the note controller WKNTC via the I / F) and processed.

Here, it is assumed that the note controller WKNTC has the same processing capability and function as a recent pen computer. Therefore, the microprocessor MPU

The liquid crystal display sheet SHT1 includes the sheet controller SHTC1 and two liquid crystals L as described above.

1, S2, S3, and the block of the battery CELL1.

The sheet controller SHTC1 has a function for developing code data such as characters and figures into image information, and like the note controller WKNTC, the microprocessor MPUS1 and memory (ROM-S1, RAM).
-S1), interface with LCD LCD11 I /
F, LCD12 I / F, and interface SHT-S I / F with the main body WKNT.

Now, an outline of the operation and operation of the notebook type information processing apparatus of FIG. 4 will be described.

First, the position indicator P and the position indicators S1 and S
2 and S3 are composed of a coil and a capacitor element, and the coordinate can be detected by utilizing a physical phenomenon in which this element resonates at a specific frequency. That is, the coordinate input device TB sequentially supplies a specific frequency to the X and Y axis sensors of the TB, and detects the coordinate by utilizing the change in impedance due to the resonance with the capacitor element. The stylus pen coordinates can be detected in the same way. At this time, the resonance frequency of the stylus pen PEN and the resonance frequencies of the position indicators P, S1, S2, S3 described above need to be different in order to identify each other.

The coordinates are input via the interface TB I / F, and the corresponding processing is performed by the microprocessor M.
It is performed by PU-M. On the other hand, stylus pen PEN
The screen control sensor SR
L1, SRL2, PGC are interface PAGE
Input is made via the I / F, and screen scrolling and page switching control of the liquid crystal display are performed. A touch sensor or a volume may be used as the screen control sensors SRL1, SRL2, PGC. Screen scrolling and page switching (this page is a page within one screen) can be performed by software instructions on the display screen of each liquid crystal display, but as in this embodiment, it is common to each liquid crystal display. By providing it as hardware on the main body side, it is possible to operate by effectively using the vacant left hand. In particular, page switching can be performed with the feeling of turning pages of an actual book.

As a specific usage method, for example, when a touch sensor is used as the sensor, the page switching sensor P
The page position operation of the GC, ie, the left coordinate position from the center position, corresponds to the page feed operation, and the right coordinate position corresponds to the page return operation. The speed of page switching may be changed depending on the size of the coordinate value (larger when the position is farther from the center). Use a resistance type volume for the sensor,
The page switching speed can be made variable according to the magnitude of the value. Also, the page switching sensor P
It is also possible to use two GCs, one of which corresponds to a page feed operation and the other of which corresponds to a page return operation.

Sensors SRL1 and SR for screen scrolling
With respect to L2 as well, similarly to the case of using the touch sensor, both scrolls can be controlled by the magnitude of the coordinate value.

Since the interface can be achieved by making full use of both hands in this manner, man-machine performance can be improved.

A paper original is read by the two-dimensional surface sensor SC, and this data is displayed on the display sheets (SHTC1, STC).
It can be displayed on HTC2 and SHTC3). The operation is as follows. When a document is placed on the two-dimensional surface sensor SC and a scanner driving menu or icon is designated with the stylus pen, scanning is started and the images are sequentially displayed from the read image and displayed on the display sheet. Of course, unlike when using a one-dimensional sensor, reading is instantaneous. The read image is compressed and stored in the memory RAM-M, and if necessary, a server (SV1, S1 in FIG. 1 connected to the network NET.
SV2), for example, it is possible to print by sending to the print server, or to send the original to the partner facsimile using the facsimile server. As described above, since the notebook type information processing device is positioned as a personal information device, it is possible to share system resources and effectively use a database by using the system via a network.

Returning to FIG. 4, the notebook type information processing device WKN
How to display the information processed in T1 on the liquid crystal display sheet SHT1 will be described below.

To input information, first, the coordinate input device T
The handwritten memo data of B is TB I / F as coordinate data.
Sheet interface SHT-M
It is displayed as a set of coordinate points on the liquid crystal LCD 11 or LCD 12 of the liquid crystal display sheet SHT1 via the I / F and SHT-S I / F.

Character data and graphic information generated by the notebook type information processing device WKNT1 are transmitted to the liquid crystal display sheet SHT1 together with code data indicating the character and graphic information and position coordinate data to be displayed. Liquid crystal display sheet SH
At T1, the received code information and position information are interpreted and the character font data (stored in ROM-S1) and the graphic image are stored in the display memory (RAM-S1). This display memory is used as a liquid crystal display interface LCD11 I / F.
Alternatively, the liquid crystal LC is periodically supplied via the LCD 12 I / F.
D11, LCD 12 is displayed.

The image data taken in by the two-dimensional surface sensor SC is compressed (for example, a facsimile encoding method MR compression) and similarly transmitted to the liquid crystal display sheet SHT1. The liquid crystal display sheet SHT1 can be displayed by expanding the received image data and storing it in the display memory.

Further, various information from the host system is
Interface WT through wireless network NET1
It can be captured via the I / F, transmitted to the liquid crystal display sheet SHT1 in the same manner as described above, and displayed on the liquid crystal display sheet.

As described above, in the block configuration of the embodiment of the present invention, the controller WKN which mainly performs information processing.
Controller SHTC that mainly performs TC and display processing
It has a multiprocessor configuration of 1 to SHTC3.
As a result, the processing performance is improved, the interface is simplified, and the liquid crystal display sheet is independent and has the effect of flexibility. For example, as another embodiment of the present invention,
The LCD display sheet can be detached and clipped on the front of the office partition for display.
At this time, data communication from the notebook type information processing device main body,
You can change the display. However, the coordinate input device T
Since it is separated from B, it becomes impossible to directly instruct the screen.

Next, the method of detecting the page position of a plurality of liquid crystal display sheets and the method of matching the coordinates of the input display, which are features of this embodiment, will be described with reference to FIG.

In FIG. 5, the cover coordinate input device TB has one coordinate system, and has a flexible structure especially at the center coordinate xc, and can be folded in two. Of course, two physically different coordinate input devices may be used to logically form one coordinate input device. The position indicators S1 to S3 of each sheet are provided at the peculiar y coordinate position of the edge of each page. The position indicator P is provided on the back cover side of the cover. As described above, the four position indicators resonate at the same frequency. The coordinate input device TB can detect the coordinates at these four locations. Depending on the presence of this coordinate value and the positional relationship, whether the cover cover is open,
You can easily determine which page is open. With a specific page open, the coordinates of the position indicators S1 to S3 of the sheets SHT1 to SHT3 are respectively changed to S1 (x1, y).
1), S2 (x2, y2), S3 (x3, y3). The opened page can be recognized depending on whether each of these coordinates is on the left or right side of the x-axis center coordinate xc. Further, the x-axis inverted coordinate P ′ of the coordinate of the position indicator P is (x4, y4). Regarding the position indicator P, when the coordinates are detected at the facing position P ′ on the front cover side, it can be determined that the cover is closed.

Specifically, the determination is made by the method shown in FIG. Since the y-axis coordinate of each position indicator is physically fixed (almost the same), it can be determined by the x-axis coordinate position of each position indicator. Here, since there are three liquid crystal display sheets, the page numbers are P1 to P6 counting from the left.
In FIG. 6, whether or not the cover and each page are open can be known by determining whether Condition 1 or Condition 2 is satisfied. In the figure, a circle of a condition indicates that the condition is satisfied. The parentheses in Condition 2 indicate a position indicator without coordinate detection. In the example of FIG. 6, the condition (P open) that the cover cover is open is that condition 2 is satisfied regardless of condition 1, that is, the coordinates of the position indicator P are not detected. Further, the condition (P1 open) that page 1 is open is that (S1 (x1, y1)> xc) and (S2 (x2, y2)> xc) and (S3 (x3, y3)> xc). When there is no coordinate detection for S1, it can be seen that both page 1 and page 2 are open, that is, in the middle of page turning.

The same applies to other pages.

Next, a software configuration diagram of the embodiment of the present invention will be described with reference to FIG. In FIG. 7, the software is roughly divided into an operating system OS and application software AP. Here, the solid line shows the data flow and the dotted line shows the control flow.

First, the OS will be described. Position indicator S1
The signals from S3 to S3 are processed by page position detection processing (OS1
0), input display coordinate matching processing from the current coordinate position (OS
20) is performed. On the other hand, it is determined which page is open, and the recovery process of the program corresponding to the page is performed (OS30). Program recovery is applied software AP
Either of them will return.

Next, the cover open / close detection is performed by the cover open / close detection process (OS40). When the cover is opened (turned on), the authentication process is first performed (OS50) to confirm that the user is the user who was using the application. This authentication processing is performed by inputting a password or ID, or by inputting a signature in addition to or instead of this. If you are the person
If it is confirmed, the program goes to the previous program restoration process and the program being processed is restored (OS30). Of course, if it is found that the person is not the person himself, he will not go to the program restoration processing.

On the other hand, the cover cover was closed (off).
At this time, temporarily save the program currently being processed,
Prepare for the next cover cover opening operation (O
S60).

Coordinates input from the coordinate input device TB are subjected to coordinate input processing (OS70), coordinate conversion, and handwritten character recognition processing (OS80) and handwritten edited symbol recognition processing (OS90). . These recognition results are passed to the application software and a corresponding process is performed.
The output of the coordinate input device TB is also output to the window processing at the same time, and multi-window processing is performed (OS1
00).

Screen control sensors SRL1, SRL2, P
The signal processing of the GC is performed at the same time as the signal detection, and the corresponding processing is performed (OS110). That is, the sensors SRL1, S
When RL2 is detected, the screen scrolling process within the page is performed, and when the sensor PGC is detected, the page turning process is performed. Therefore, this process is closely related to the window process. The window processing (OS100)
Application software (OS) and sheet display processing (OS12
0) to control the man-machine interface.

Further, the output of the two-dimensional surface sensor SC is converted into a binary image by image input processing to create an image data file (OS130).

Next, although there are various kinds of application software, which are often used in office, mail processing (AP10), schedule processing (AP20), word processing (AP30), spreadsheet processing (AP40), database. There is a process (AP50). Other application software will be omitted. Each of these application software is a task and can be processed simultaneously. In the present invention, these tasks are processed corresponding to pages. As a result, when a page is opened, the task assigned to the page is activated and the saved state can be directly entered.

Besides assigning tasks to pages,
Plural pages may be assigned to one task (application software). In this case, since a plurality of screens can be used, more efficient work can be performed.

As described above, according to the embodiments of the present invention, the following effects can be obtained.

Since one coordinate input device also serves to input coordinates to a plurality of liquid crystal display sheets, the thickness of the liquid crystal display sheets can be made thin, and thus page turning can be performed easily like a notebook. Since the main body and the liquid crystal display sheet each have a controller, the performance is improved and the interface is simplified.

Further, since the open / close detection of the page position and the open / close detection of the cover cover are performed by the method using the coil and the capacitor, the power supply and the active element are unnecessary, and the system can be constructed at a low cost.

Further, since the structure is foldable, portability is improved.

Another embodiment of the present invention will be described below.

FIG. 8 is a block diagram of another embodiment of the present invention. In FIG. 8, a liquid crystal video signal is used as an interface between the main body and the liquid crystal display sheet. This method has the drawback that it has more interface signal lines and a higher transfer rate than the previous embodiment of the present invention, but the sheet controller (SHTC1) is not required.

FIG. 9 shows still another embodiment. In this embodiment, liquid crystal display sheets SHTa and SHTb are used.
The page position detecting method in the case of separating the individual pages and freely arranging them on the coordinate input device TB is described. In this case, in particular, since the seat can be freely arranged, the two position indicators Sa1, for detecting the rotation with the coordinate input device TB1.
Sa2 (Sb1, Sb2) is required. Rotation detection is S
a1 (x1, y1) and Sb1 (x2, y2) or Sb
It can be easily calculated from the coordinates of 1 (x3, y3) and Sb2 (x4, y4). Therefore, it is necessary to take this inclination into consideration when converting the input coordinates into the display coordinate system of the liquid crystal display sheet.

Further, as another application example of the case of FIG. 9, a case where the entire conference desk is used as a coordinate input device and a processing device and a liquid crystal display sheet is used as a material for conference participants will be described. That is, the same screen is displayed to the conference participants, and each of them can freely write notes or point on the liquid crystal display sheet if necessary. At this time, in order to identify who is inputting, the cursor shape and the color of the memo writing are changed. The resonance frequency of each stylus pen is set individually to accept multiple coordinate inputs. The stylus pen may be distributed to the conference participants in advance or distributed on the spot. Therefore, it is not necessary to distribute a copy or bring a file as in a conventional conference, and a paperless electronic conference can be realized.

In the free separation method, it is difficult to determine which page is being accessed when a plurality of pages overlap each other. Therefore, a predetermined promise is required. For example, consider a method that always determines the page with younger coordinate values as upper (or lower), a method that prioritizes pages that have been input until then, and a method that makes pages inaccessible when they overlap. To be

In the case of the example shown in FIG. 9, the liquid crystal display sheet is free to be cut off, so that it can be hung by sandwiching the paper like normal paper. At this time, when the display is left for a long time, it is necessary to increase the battery capacity or supply power from the outside.

The preferred embodiment of the present invention has been described above, but various modifications are possible. For example, as the page position detecting method of the above-described embodiment, as shown in FIG. 5, the position of the position indicators S1 to S3 is placed above the y-axis center line, but this is below the y-axis center line. You may leave it on one side. In particular, since the page turning operation is often performed on the front side of the sheet, it is convenient when the page is being displayed. This is because it is determined that the page is open as shown in FIG. 6 because the page coordinates are not detected when the page is being turned.

In the embodiment of the present invention, the method of detecting the page position uses a coil and a capacitor, but other methods include a method of detecting a specific magnetic mark and a method of using an optical sensor. . In either method, it suffices to know the page opening / closing and coordinate position.

Further, in the embodiment of the present invention, the liquid crystal display sheet is displayed on both sides as shown in FIG. 3, but it may be displayed on one side. In this case, the display information amount is reduced, but the display sheet is further thinned.

[0082]

According to the present invention, the coordinate input device is also used for a plurality of flat displays, which contributes to the thinning and cost reduction of the information processing device.

Further, it is possible to detect which page is open by detecting the coordinates unique to each page, and if this page position detecting means and program saving / restoring means are associated with each other, it is opened at the same time. The program running on that page can be restored, and the necessary work can be immediately started. This improves work efficiency.

Further, the power of the information processing apparatus is turned on at the same time when the cover is opened by linking the opening / closing detection means for detecting the opening / closing of the cover cover with the power on / off of the information processing apparatus and the program saving / restoring means. A predetermined processing program is activated. In this way, the operation is intuitive and man-machine performance is greatly improved.

The display sheet allows two-sided display by laminating two liquid crystal elements, and an opaque color sheet is inserted between them to form one display sheet, thereby eliminating the interference due to mutual display and simultaneously displaying colors. By using a sheet (or paper), it is possible to distinguish the processing programs by color and improve the intuition.

Further, by mounting the two-dimensional surface sensor type scanner on the notebook type information processing apparatus itself, since there is no mechanical mechanism, the paper information can be easily read at high speed, and it is small and portable. .
