The host computer 8 is connected to the output line 8101b of the output control circuit 101, and is connected to the data input/output control circuit 11.
4 and an input/output line 13114b, and the file device 9 is connected to an input/output line S8. The refile device 9 of the host computer 8 stores a data file of (n 1) pages as shown in FIG.

Next, the operation of this embodiment will be explained. When the device is powered on, the screen/convolution control circuit 100 connects the input/output lines 510 to
0c instructs the data input/output control circuit 114 to load the display data file. Upon receiving this instruction, the data input/output control circuit 114 requests the host computer 8 to transfer the display data aisle through the input/output 1s11b. The host computer 8 edits the display data file (FIG. 2) of n pages from the data file (FIG. 3) of the file device 9, and notifies the data input/output control circuit 114 through the input/output line 8114b when the transfer is possible. After that, the data of the display data file is transferred in order.

This data is stored in the memory 3 via the input/output line 8114a under the control of the data input/output control circuit 114. After transferring the last data of the display data file, the host computer 8 issues a completion notification to the data input/output control circuit 114. Data input/output control time! Upon receiving the notification, the screen/convolution control circuit 6114 notifies the screen/convolution control circuit 100 through the input/output line 5100°.

The screen/write control circuit 100 is now in the normal mode.

Next, the operation of inputting data to the host computer 8 will be explained. The operation flow in that case is shown in FIG.

In normal mode, turn Table of Contents key switch 4 on and off.
The encoder 102 outputs a code C (page number) corresponding to the table of contents key switch 4.

This is register 1 along with self-write switch OFF information.
Incorporated into 03. The screen/convolution control circuit 100 reads the contents of the register 103, and when the contents of the page register 108 are other than the table of contents page number, writes a new table of contents page number to the page register 108, and outputs the OR gate 1.
Turn on the output line si 00g to 07 and selector 105
The output line 5105b side gate is closed, and the output line 810
Open the gate on the 5a side.

Next, the screen/'9F' control circuit 100 connects the output line 8
100alC opens the gate of selector 111,
Further, the output line 5100b causes the selector 112 to open the gate on the output line 5112a side and the selector 113 to open the gate on the output line S5 side. As a result, register 1
The data of 03 is inputted to the memory 6 as the upper address, and the output of the address counter 104 is inputted as the lower address. The address counter 104 automatically counts up in synchronization with the screen scanning of the display device 1.

Thus, the codes of the table of contents page of the display data file are sequentially read from the memory 6 in synchronization with screen scanning and sent to the pattern generator 106. pattern generator 106
generates a pattern corresponding to the received code and sequentially sends it to the display device to display it on the screen.

FIG. 4(a) shows an example of the screen display at this time (the screen seen through the touch panel 2). Each item data on the table of contents page is displayed in a fixed order at each item display position indicated by the dashed line grid. That is, the item data at the top of the page is displayed at the leftmost item display position at the top of the screen, the quintic item data is displayed at the right item display position, and so on.

By specifying the item display position, you can specify specific item data on the table of contents page (same as the main text page). Moreover, the item data in the table of contents page is arranged in correspondence with the page number of the corresponding text page, and each item data of the table of contents data represents a title indicating the content of the corresponding text page. Therefore, K while displaying the table of contents page.

A desired text page can be easily specified by searching for the title of the desired text page and specifying the item display position where it is displayed.

With the table of contents page being displayed in this manner, when a portion of the touch panel 20 corresponding to the item display position trap where the title of the desired text page is displayed is touched, the encoder 110 sends a detection signal output from the touch panel 2 to Encode the Y coordinate code. This X, Y coordinate code is
The page number 9 corresponding to the item display position is encoded via the selector 105 to the encoder 102 and stored in the register 103.

The screen/1-inclusive control circuit 100 controls the contents of the register 103 (
After reading the page number) and confirming that it is different from the contents of the page register 108 (in this case, the page number of the table of contents page), the gate on the output line 8105a side of the selector 105 is turned off by turning off the output signal 8100g to the OR gate 107. Close the gate and bend the gate on the output line 5105 side.

The selected states of the selectors 111, 112, and 113 remain as they are, data 2 of the register 103 and the value of the address counter 104 are input to the memory 6 as addresses, and the code of the text page corresponding to the specified item display position is stored in the memory 5. is output from.

This is converted into a pattern by the pattern generator 106 and displayed on the display device 1.

For example, in Figure 4(a),! If you specify item A, ``Business Office Name,'' the display screen will change as shown in Figure 4.

When the display position of a desired data item in the text page is specified on the touch panel 2 while the text page is displayed, the xtyffi mark code of the item display position is displayed on the encoder 11.
Output from 0. In the text page display mf'dJic, the selector 105 is connected to the gate of the output line 51osbf (U, so the X, Y coordinate code is input to the encoder 109.
The coordinate code and the value of the page register 108 (page number being displayed) are coded together and input to the host computer 8 through an output line 5109.

The host computer 8 identifies the corresponding page in the data file using the page number information included in the input code, and uses the page number information included in the input code to identify the page in the data file.

The corresponding data item in the page is identified using the Y coordinate information, and its contents are imported from the file device 9. with this,
This means that one data item has been input.

All desired data items included in the text page being displayed are sequentially input by specifying them on the touch panel 2 in the same manner.

If you want to input from another text page, turn on the Table of Contents key switch 4 to call up the Table of Contents page, and press the touch panel 2
Specify and display the desired text page using , and similarly specify input data items using the touch panel 2 .

#, pp key switch 5, English symbol key switch 10,
When each of the kana key switches 11 is turned on, the program function, English symbol, and kana pages stored in the memory 31 are displayed in the same manner as the main text page, and the selector 105 The gate on the output line 5105a side is closed. That is, only when the table of contents page is displayed, the gate on the output line 5105a side of the selector 105 is opened, and 5tosblI! l
gate will be closed. When displaying a page other than the monthly page, the selection of the selector 105 is reversed.

When the self-write switch 6 is turned on, the multi-item input device according to the present invention is in a self-write mode and is busy so that the device itself can create or modify the display data file. The operation in this case will be explained next, and the operation steps are shown in FIG.

First, turn on the self-write switch 6 (this switch is locked in the on state until it is operated again). As a result, the output line S6 of the self-convolution switch 6 is turned on, so the output signal 8107 of the OR gate 107 is turned on.
The selector 105 closes the gate on the output line 5105b side,
Open the gate on the output line 5iosa side.

When you turn on the next busy table of contents key switch 4, encoder 1
A table of contents key code is output from 02, and it is taken into register 103 along with self-writing switch-on information. Screen/write control circuit 100 reads the contents of register 103 and writes page register 108 . When the content of is a page number other than the table of contents page, the table of contents page number is written to the page register 106. Next, the screen/write control circuit 10
0 causes the gate of the selector 111 to be opened by the output line Sj 00a, and the output line ! to the selectors 112 and 113 by the output line S 10' Ob. Open the gate on the 3112a side and the gate on the input/output line S3 side.

As a result, the contents of the register 103 (excluding self-write switch-on information) are input to the memory 3 as the upper address and the value of the address counter 104 as the lower address, and the data of the table of contents page is sequentially read out from the memory 6. This data is sent through the selector 113 to the pattern generator 106, where it is converted into a pattern and displayed on the display device 1.
will be displayed.

In this manner, with the table of contents page displayed, the user touches a desired item display position on the touch panel 2 to specify the text page on which data is to be input or modified. X of the touched item display position.

A Y coordinate code is output from the encoder 110, which is input to the encoder 102 via the selector 105,
It is encoded in the page number code of the corresponding text page. This page number is captured in register 105 along with self-writing switch-on information.

When the content of the page register 108 is a table of contents page, the screen/write control circuit 100 rewrites the page register 108 to the designated text page number.

The selection states of selectors 111 and 112i13 do not change. Therefore, the data of the designated text page of the 5 display data file is read out from the memory 3, inputted to the pattern generator 106 via the selector 113, and the pattern is displayed on the display device 1.

While the text page is displayed, touch the item display position on the touch panel that corresponds to the data item you wish to input or modify. The x, y coordinate code of the display item position is output from the encoder 110, which is input to the encoder 102 via the selector 105 and encoded. This code is loaded into register 103 along with self-writing switch-on information.

The screen/write control circuit 100 determines whether the content of the page register 108 is a code specified by the touch panel that includes table of contents key-on information, or if the content of the page register 10 is other than the table of contents page, it is only a code specified by the touch panel. If the conditions are met, the page number and item position information to be self-written are written to the page register 108. Then, all gates of selectors 111, 112, and 115 are closed.

Next, the screen/write control circuit 100 specifies the address corresponding to the data item of the text page on which self-writing is to be performed to the memory 3 via output lines 5100θ and 5100f, and the contents of the data item (existing data ) is read from memory 3. At the same time, due to the output line 51ooa,
Memory address corresponding to existing data area on screen?
i2, and the data read from the memory 6 is loaded into that address.

After writing this data, the screen/writing control circuit 10
0 causes the selector 112 to open the gate of the output line 5112bllQ through the output line 5100b.

The value of the address counter 104 is input to the memory 32, and the gate on the input/output line s32 side of the selector 113iC is opened. As a result, the contents of the memory 32 are sent to the pattern generator 106 through the selector 115, converted into a pattern, and displayed on the display device 1.

An example of the screen display at this time is shown in FIG. This is an input data area, which will be explained later.

Next, you will need to enter correction data for the existing data (the existing data may contain spaces), but it is difficult to determine whether the characters to be entered are kanji/hiragana, English symbols (including numbers), or katakana. , the operations are different.

If you want to input kanji or hiragana, turn on the table of contents key switch 4. A table of contents key code is output from the encoder 102 and latched into the register 103.

The screen/write control circuit 100 doubles the page number of the writing table of contents page in its internal latch, and outputs the address of the folding table of contents page 1si00e.

B100rkC is sent to the memory 31, and the display code of the table of contents page to be sent is sequentially outputted from the memory 31 to the output line S31. At the same time, the address of the data area for 1 convolution is specified in the memory 32 by the output line 5i00d, and the display code of the table of contents page for writing is stored in the data area for writing on the memory 52. At this time, selectors 111, 112
and 113 gates are closed.

When the transfer of the display code of the table of contents page for writing is completed, the screen/write control circuit 100 closes the gate on the output line 511zb side of the selector 112 and the gate on the input/output line 832 side of the selector 1130 via the output line 5100b. . As a result, the contents of the memory 32 are sequentially read out and sent to the pattern generator 106, and the pattern is displayed on the display @1.
will be displayed.

An example of the display screen at that time is shown in FIG. This writing table of contents page contains 50 syllables, consonants, voiced sounds, and half-voiced hiragana, and is used to specify the hiragana to be written or the sound of the kanji to be written.

Next, when you touch the item display position on the touch panel 2 where the desired hiragana is displayed, the X appears.

The Y coordinate code is sent from the encoder 110 to the encoder 102 via the selector 105, encoded, and taken into the register 103.

If the internal launch data is a writing table of contents page, the screen/write control circuit 100 re-holds the contents of the register 103 (the code corresponding to the hiragana specified by the touch panel) in an internal latch, and writes it to the specified flat plate. The display code of the kanji/kana page corresponding to the name is transferred from the memory 31 to the writing data area of the mesori 62. The addresses of the memories 31 and 52 at this time are output +tj8100d, 5100e, as in the case of the writing table of contents page.

[Conducted] through 5100f. During this transfer, the selector 111. Selector 112. All gates of selector 115 are closed.

When the data transfer is finished, the screen/write control circuit 100 outputs the output line 5 of the selector 112 through the output line 51oob.
112b side gate is opened, and the selector 1130 input/output line +332 side gate is opened. As a result, the address specified by the address counter 104 causes the memory 5
The contents of 2 are read out the first time and displayed on the table-water device 1.

For example, if you specify the hiragana ``a'' on the writing table of contents page, you will receive patterns of the hiragana ``a'' and various kanji with the ``a'' sound in several different sizes. A space is displayed in the write data area 202.

When a desired character is specified using the touch panel 2, the specified x and y coordinate code is encoded by the encoder 102 and then taken into the register 103.

The screen/write control circuit 100 reads the contents of the register 103 (at this time, since the contents of the internal latch are not the writing contents page, the latch is not rewritten), and reads the contents of the internal latch corresponding to the position specified on the touch panel. The address to be written is specified in the memory 31 by the output lines S100, 810Or, and at the same time, the address corresponding to the character writing position in the input data area is specified in the memory 321C. This results in
The display code of the specified character is transferred to the character writing position in the memory 62. At this time, selectors 111, 112.11
Close all gates in 5.

After that, the screen/write control circuit 100 selects the selector 112
The gate on the output line +3112b side of the selector 115 and the gate on the input/output line 832 side of the selector 1150 are opened, and the contents of the memory 32 are displayed on the display device. As a result, the character pattern specified on the touch panel is displayed at the writing position in the input data area 201.

In addition, in the input data area 201, characters are written in order from the left end to the right end in the upper row, and when the right end is reached, characters are written in order from the left end to the right in the lower row. 100 performs address control. Also, if you want to write a space, you just need to touch the space part of the display panel. If you want to input two or more hiragana or kanji characters with the same sound, or two or more spaces, you can specify the characters one by one using the touch panel 2.

When writing the necessary characters into the input data area 201 is finished, the input data area 201 of the touch panel 20 is touched. The X, Y coordinate code corresponding to the input data area is encoded by encoder 102 and stored in register 1.
Incorporated into 06.

The screen/write control circuit 100 includes selectors 111 and 112.
．． 113 are closed, and the address of the input data area 201 is designated to the memory 32 by the output line 51ooa. At the same time, the address is based on the page number and item position information of the text page to be folded held in the page register 108.

Memory 3 is designated as busy using output lines 5100e and 5100f, and the code of the written character is transferred from memory 52 to memory 6. This completes the creation or modification of the specified data item on the specified text page.

To return to the normal mode, turn on the self-write switch 6.

If you want to write katakana or alphanumeric characters (including numbers), press the kana key switch 11 as shown in Figure 7.
Or turn on the English symbol key switch 1o. Then, the contents of the kana page or the alphabet page are transferred from the memory 31 to the memory 32 by the screen/write control circuit 100 and displayed on the display device 1.

Then, a desired character is specified using the touch panel 2.

Then, as with kanji and hiragana, the screen/
As the write control circuit 1000 is busy with control, specified character codes are sequentially written into the input data area of the memory 52 and displayed on the display device IK. The subsequent operations are as described above.

FIG. 5(c) shows an example of the display after character input is completed.

As explained above, in the multi-item input device according to the present invention, a new display data file can be created or modified at will on the device itself.

In order to save the newly created display data file or the modified display data file, the send key provided in the key switch group 12 is turned on. Then, the code of the send key is encoder 10
9 is input to the screen/write control circuit 100. screen/
The write control circuit 100 activates the data input/output control circuit 114 to transmit through the input/output line 8100o. Then, the data input/output control circuit 114 controls the input/output line B11.
After notifying the host computer 8 of the start of transmission by 4bK, the codes of the display data file are sequentially read from the memory 3 and transferred to the host computer 8.

The host computer 8 once stores the code of the transmitted display data file in the file device 9, and then updates the data file.

Above, one embodiment of the present invention has been described in detail 1c.
The present invention is not limited thereto.

For example, in the self-writing mode, a dedicated input device for inputting character data may be provided. However, the configuration of the above embodiment is more advantageous in general for buttons that realize the device at a lower cost.

As the memory 3, a rewritable nonvolatile memory can be used. In this case, there is no need to load the display data file from the host computer 8 into the memory 6 during power-on.

It is also possible to place the memories 31, 32 above the memory 6.

Furthermore, if there are many UI types of writing data, display multiple characters at one item display position on the touch panel 2, specify the multiple characters displayed at one display item position by touching the touch panel 2, It is also possible to designate one character from the character group using the key switch group 12.

Also, display the cursor in the input data area 201,
The cursor may be moved arbitrarily using the cursor movement keys on the key switch group 12 and pressed to specify the position containing the first character.

Furthermore, instead of the touch panel, a switch or light bar may be used to specify the position on the screen.

However, touch panels are generally more advantageous in terms of cost than light panels, and are also much more advantageous in terms of operability than using switches.

Furthermore, if the contents of the data actually input can be displayed as they are, it goes without saying that the data file on the host computer side may be used as the display data file.

In addition, if there are many data items and it is difficult to combine them into one display data file, you can divide the display data file into blocks, prepare a table of contents page for each block, and select the necessary blocks. good. In that case, an index page may be prepared in which the content of each block is titled as the same as the table of contents page, and this index page may be treated in the same manner as the table of contents page to perform the selection.

Additionally, the functions of the screen/write control circuit 100 may be realized by software.

〔Effect of the invention〕

The present invention has been described in detail above, and the following effects can be obtained.

(11) The user of the multi-item input device can create or modify the display data file as desired.

(2) When creating or modifying the display data file,
Since characters are input by specifying the characters actually displayed, creation and modification of one display data file can be easily and error-free.

(3) Because text pages and data items are specified not by the display content itself, but by specifying the display position on the screen, even if the contents of one display data file are changed as described above, it will not be possible to use the conventional Zook format or There is no need to change or replace the information in the pregnancy book or key tops, such as with a multi-item input device with a set of keys, making maintenance and management extremely easy and easy, and creating and modifying display data files is also easy.

(4) Since the table of contents page can be displayed and the titles indicating the contents of many text pages can be viewed, the necessary text page can be easily and quickly selected, and the operability of data entry can be greatly improved.

(5) The number of data items can be increased without deteriorating operability.

(6) Since a touch panel is used as the position specifying means, the installation cost can be reduced compared to the case where a light ben is used, and the operability can be greatly improved compared to the case where a switch is used.
