Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a multi-item input device for inputting multi-item data.

[Background of the invention]

Multi-item input devices include those that use a large number of keys to which one or more specific data items are assigned, and those that use a so-called book format.

However, in the former method, data items are displayed on key tops with a limited area, making them difficult to see. Furthermore, since there is a limit to the number of data items that can be displayed on one key top, when the number of data items is large, the number of keys increases significantly, resulting in poor operability.

In the latter case, it is difficult to understand the contents of a page, and page selection is performed by operating a limited number of switches, so the operability is not very good when the number of pages (number of data items) in a book increases.

In addition, with any multi-item input device, when modifying, adding, or deleting data items, it is necessary to change the description on the key top, replace the book, etc., and maintenance and
Not easy to manage. Furthermore, it is practically impossible for the user to freely change, add, or delete data items.

2 is input, and the selector 105 selects the encoder 11.
0 output line S110 and output line S107 of OR gate 107 are input. encoder 10
2 is an output line S4 of the table of contents key switch 4, an output line S5 of the PF key switch 5, an output line S10 of the English key switch 10, an output line S11 of the Japanese key switch 11, and an output line S1 of the selector 105.
05a has been input. The output line S6 of the self-write switch 6 is connected to the register 103 and the OR gate 10.
7 is entered. The register 103 receives the output line S102 of the encoder 102 and has an output line S103b to the selector 111. The output line S104 of the address counter 14 is input to the selector 112.

The memory 3 receives output lines S111 and S112a of the selectors 111 and 112, an output line S3 to the memory 32 and the selector 113, an input/output line S32 to the memory 32, and the data input/output control circuit 11.

No. 2 output line S112b is inputted thereto, and the memory 3 and selector 113 are connected through an input/output line S32.

The encoder 109 is supplied with the output line S12 of the numeric keypad and other key switch group 12, the output line S105b of the selector 105, and the output line S108b of the page register 108, and is also connected to the output control circuit 10.
1 through an output line S109. The pattern generator 106 connects the display device 1 and the output line S106.
The selector 113 and its output line S113 are connected to each other.

The host computer 8 has an output control circuit 101
It is connected to the data input/output control circuit 114 via an input/output line S114b, and to the file device 9 via an input/output line S8. The file device 9 of the host computer 8 has a third
A data file of (n-1) pages as shown in the figure is stored.

Next, the operation of this embodiment will be explained. When the device is powered on, the screen/write control circuit 100 instructs the data input/output control circuit 114 to load a display data file via the input/output line S100c. Data input/output control circuit 11 that received this instruction
4 requests the host computer 8 to transfer the display data file through the input/output line S114b. The host computer 8 edits the n-page display data file (Fig. 2) from the data file (Fig. 3) of the file device 9, and when it becomes transferable, notifies the data input/output control circuit 114 through the input/output line S114b. After that, the data in the display data file is transferred in order. This data is stored in the memory 3 via the input/output line S114a 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 circuit 11
4, upon receiving the notification, sends an input/output line S to that effect.
The screen/write control circuit 100 is notified by 100c. 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 scanning flow in that case is shown in FIG.

When the table of contents key switch 4 is turned on in the normal mode, the code (page number) corresponding to the table of contents key switch 4 is output from the encoder 102.
This is taken into the register 103 together with the self-write switch OFF information. Screen/write control circuit 1
00 reads the contents of the register 103, and if 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, turns on the output line S100g to the OR gate 107, and selects the selector 105. Output line S
Close the gate on the 105b side and connect the output line S105a.
Open the side gate.

Next, the screen/write control circuit 100 opens the gate of the selector 111 through the output line S100a, and causes the selector 112 to open the gate on the output line S112a side and the output line to the selector 113 through the output line S100b. Open the gate on the S3 side. As a result, the data in the register 103 is input to the memory 3 as an upper address, and the output of the address counter 104 is input as a 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 out from the memory 3 in synchronization with screen scanning and sent to the pattern generator 106. The pattern generator 106 generates patterns corresponding to the received codes and sequentially sends them to the display device 1 to display them on the screen.

FIG. 4a shows an example of the screen display at this time (the screen viewed through the touch panel 2). Each item data of the table of contents page is displayed in a fixed order at each item display position indicated by a chain 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 next item data is displayed at the right item display position, and so on.

Therefore, by specifying the item display position, it is possible to specify specific item data within 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, while viewing 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 way, if you touch the part of the touch panel 2 that corresponds to the item display position where the title of the desired text page is displayed, the encoder 110 will move the touch panel 2.
The detection signal emitted from the sensor is encoded into an X, Y coordinate code. This X, Y coordinate code is the selector 10
5 to the encoder 102, where it is encoded into a page number corresponding to the item display position and taken into the register 103.

The screen/write control circuit 100 has a register 103
Read the contents (page number) and enter page register 1.
Contents of 08 (page number of table of contents page here)
If it is confirmed that this is different, the output signal S100g to the OR gate 107 is turned off to close the gate on the output line S105a side of the selector 105 and open the gate on the output line S105 side.
The selected states of the selectors 111, 112, and 113 remain as they are, and the data in the register 103 and the value in the address counter 104 are used as addresses in the memory 3.
, and the code of the text page corresponding to the designated item display position is output from the memory 3.
This is converted into a pattern by the pattern generator 106 and displayed on the display device 1.

For example, if the item "office name" in FIG. 4a is specified, the display screen changes as shown in FIG. 4b.

When the display position of a desired data item in the text page is specified using the touch panel 2 while the text page is displayed, the encoder 110 outputs the X, Y coordinate code of the item display position. During the display period of the main text page, the selector 105 opens the gate on the output line S105b side, so
The coordinate code is input to encoder 109. The encoder 109 encodes the X, Y coordinate code and the value of the page register 108 (page number being displayed) together, and inputs the encoded code to the host computer 8 through the output line S109.

The host computer 8 identifies the page in the corresponding data file using the page number information included in the input code, and
The corresponding data item in the page is identified using the Y coordinate information, and its contents are imported from the file device 9. One data item has now 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 Table of Contents key switch 4 to call up the Table of Contents page,
Specify and display the desired text page on the touch panel 2, and similarly enter the input data items on the touch panel 2.
Specify with.

Note that when each of the PF key switch 5, English symbol key switch 10, and Kana key switch 11 is turned on, the program functions, English symbols, and Kana characters stored in the memory 31 are Each page is displayed in the same way as the main text page, and the selector 105 is connected to the output line S105a.
The side gate is closed. That is, only when the table of contents page is displayed, the gate of the selector 105 on the output line S105a side is opened, and the gate on the output line S105b is opened.
The side gate is closed. When displaying a page other than the table of contents page, the selection of the selector 105 is reversed.

When the self-write switch mode designation key 6 is turned on, the multi-item input device according to the present invention enters the self-write mode, allowing the device itself to create or modify a display data file. The operation in this case will be described next, and the operation flow is 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-write switch 6 is turned on, so the output signal S107 of the OR gate 107 is turned on, the selector 105 closes the gate on the output line S105b side, and the output line S10
Open the gate on the 5a side.

Next, when the table of contents key switch 4 is turned on, a table of contents key code is output from the encoder 102, and is taken into the register 103 together with the self-writing switch-on information. Screen/write control circuit 10
0 reads the contents of register 103, and if the contents of page register 108 is a page number other than the table of contents page, the table of contents page number is stored in page register 1.
Write in 08. Next, the screen/write control circuit 100
causes the gate of the selector 111 to be opened by the output line S100a, and to open the gate of the selector 111 by the output line S100b.
The selectors 112 and 113 open the gate on the output line S112a side and the gate on the input/output line S3 side, respectively.

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

In this manner, with the table of contents page displayed, the user touches a desired item display position on the touch panel 2 to designate 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,
This is sent to the encoder 102 via the selector 105.
and is encoded into the page number code of the corresponding text page. This page number is loaded into register 103 along with the self-write switch 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, 112, and 113 do not change. Therefore, the data of the designated text page of the display data file is read from the memory 3 and input to the pattern generator 106 via the selector 113, and the pattern is output to the display device 1.
will be displayed.

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 encoded by the encoder 110.
This is input to the encoder 102 via the selector 105 and encoded. This code is loaded into register 103 along with self-write 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 including table of contents key-on information, but if the content of the page register 108 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 in the page register 108. Then, all gates of selectors 111, 112, and 113 are closed.

Next, the screen/write control circuit 100 sends the address corresponding to the data item of the body page on which self-writing is to be performed to the output lines S100e and S100f.
The contents of the data item (existing data) are read out from the memory 3. At the same time, the output line S100d specifies an address corresponding to the existing data area on the screen in the memory 32, and the data read from the memory 3 is written to that address.

After writing this data, the screen/write control circuit 100 causes the selector 112 to open the gate on the output line S112b side through the output line S100b, inputs the value of the address counter 104 to the memory 32, and causes the selector 112 to The gate on the input/output line S32 side is opened. Thereby, the contents of the memory 32 are sent to the pattern generator 106 through the selector 113, converted into a pattern, and displayed on the display device 1.

An example of the screen display at this time is shown in FIG. 5a. In this figure, reference numeral 200 is the already data area, and item data transferred from the memory 3 to the memory 32 is displayed here. Further, 201 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 depends on whether the characters to be entered are Kanji/Hiragana, English symbols (including numbers), or Katakana. Then,
Operation is 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 latches the page number of the table of contents page for writing in its internal latch,
Output line S100 for the address of the table of contents page for writing.
e and S100f to the memory 31, and the display code of the table of contents page for writing is sequentially outputted from the memory 31 to the output line S31. At the same time, the address of the write data area is specified in the memory 32 by the output line S100d, and the display code of the write table of contents page is stored in the write data area on the memory 32. At this time, the gates of selectors 111, 112 and 113 are closed.

When the transfer of the display code of the table of contents page for writing is completed, the screen/writing control circuit 100 outputs the output line S1.
00b causes the output line S112 of the selector 112 to
The gate on the b side and the gate on the input/output line S32 side of the selector 113 are opened. As a result, the contents of the memory 32 are sequentially read out and the pattern generator 1
06, and the pattern is displayed on the display device 1.

An example of the display screen at that time is shown in FIG. 5b. In this figure, a shaded area 202 is a writing data area, and in this case, the contents of the writing table of contents page are displayed here. This writing table of contents page contains 50 sounds, consonants, voiced sounds, semi-voiced sounds, and hiragana, and is used to specify the sounds of hiragana or kanji to be written.

Next, when you touch the item display position on the touch panel 2 where the desired hiragana is displayed, its X, Y coordinate code is sent from the encoder 110 to the encoder 102 via the selector 105.
It is encoded and taken into the register 103.

The screen/write control circuit 100 controls the register 10 if the data in the internal latch is a table of contents page for writing.
The contents of 3 (the code corresponding to the hiragana specified on the touch panel) are held in the internal latch again, and the display code of the kanji/kana page corresponding to the specified hiragana is transferred from the memory 31 to the write data of the memory 32. Transfer to area. At this time, the addresses of the memories 31 and 32 are specified by the output lines S100d and S100, as in the case of the writing table of contents page.
e, S100f. During this transfer, all gates of selector 111, selector 112, and selector 113 are closed.

When the data transfer is finished, the screen/write control circuit 100 outputs data to the selector 1 through the output line S100b.
12 to open the gate on the output line S112b side, and also open the gate on the input/output line S32 side of the selector 113. Thereby, the contents of the memory 32 are sequentially read out by address designation by the address counter 104 and displayed on the display device 1.

For example, if you specify the hiragana ``a'' on the table of contents page for writing, there will be patterns of the hiragana ``a'' and various kanji with the ``a'' sound in several sizes, as well as spaces of several sizes. It is displayed in the write data area 202.

When a desired character is specified using the touch panel 2, the specified X, Y coordinate code is displayed on the encoder 1.
After being encoded by 02, register 10
It will be incorporated into 3.

The screen/write control circuit 100 has a register 103
(At this time, the content of the internal latch is not a table of contents page for writing, so the latch is not rewritten), and the address corresponding to the position specified on the touch panel is sent to the output lines S100 and S10.
0f is specified in the memory 31, and at the same time, the address corresponding to the character writing position in the input data area is specified in the memory 32. As a result, the display code of the designated character is transferred to the character writing position in the memory 32. At this time, selectors 111, 11
2,113 all gates are closed.

Thereafter, the screen/write control circuit 100 opens the gate on the output line S112b side of the selector 112 and the gate on the input/output line S32 side of the selector 113, and displays the contents of the memory 32 at the display device position. As a result, the character pattern specified on the touch panel will be transferred to the input data area 20.
It will be displayed at writing position 1.

The screen/write control circuit is configured such that characters are written in the input data area 201 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 leave the display in the write data area 202 as is and specify the characters one by one using the touch panel 2.

When writing the necessary characters into the input data area 201 is completed, the input data area 201 of the touch panel 2 is touched. The X, Y coordinate code corresponding to the input data area is encoded by the encoder 102 and taken into the register 103.

The screen/write control circuit 100 includes a selector 11
All gates 1, 112, and 113 are closed, and the address of the input data area 201 is designated to the memory 32 by the output line S100d. At the same time, an address based on the page number and item position information of the text page to be written held in the page register 108 is sent to the memory 3 via output lines S100e and S100f.
and store the code of the written character in memory 32.
from there to memory 3. This completes the creation or modification of the specified data item on the specified text page.

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

If you wish to write katakana or alphanumeric characters (including numbers), turn on the kana key switch 11 or the alphanumeric key switch 10, as shown in FIG. Then, the screen/write control circuit 10
0, the contents of the kana page or the alphabet page are transferred from the memory 31 to the memory 32 and displayed on the display device 1.

Then, use the touch panel 2 to specify the desired character. Then, as in the case of kanji and hiragana, the specified character codes are sequentially written into the input data area of the memory 32 and displayed on the display device 1 under the control of the screen/write control circuit 100. The subsequent operations are as described above.

An example of the display when character input is completed is shown in FIG. 5c.

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

In order to save the newly created display data file or the modified display data file in this way, the transmit key provided in the key switch group 12 is turned on. Then, the code of the transmission key is input from the encoder 109 to the screen/write control circuit 100. The screen/write control circuit 100 activates the data input/output control circuit 114 to transmit through the input/output line S100c. Then, the data input/output control circuit 114 notifies the host computer 8 of the start of transmission through the input/output line S114b, and then sequentially reads out the codes of the display data file from the memory 3 and transfers them 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.

Although the present invention has been described in detail with respect to one embodiment, the present invention is not limited thereto.

For example, in the self-write mode, a dedicated input device for inputting character data may be provided. However, the configuration of the above embodiment is generally more advantageous in realizing the device at low 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 3 every time the power is turned on.

It is also possible to place the memories 31 and 32 above the memory 3.

Furthermore, if there are many types of data to be written, multiple characters can be displayed at one item display position on the touch panel 2, and the multiple characters displayed at one display item position can be specified by touching the touch panel 2. , one character in the character group is set to key switch group 1
It is also possible to have a configuration specified by 2.

Alternatively, a cursor may be displayed in the input data area 201, and the cursor may be moved arbitrarily using the cursor movement keys on the key switch group 12 to specify the character writing position.

Furthermore, instead of the touch panel, a switch or a light pen may be used to specify the position on the screen. However, a touch panel is generally more advantageous in cost than a light pen, and is also much more advantageous in terms of operability than using a switch.

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 it is as the display data file.

Furthermore, if there are many data items and it is difficult to combine them into one display data file, the display data file may be divided into blocks, a table of contents page may be prepared for each block, and the necessary block may be selected. In that case, an index page may be prepared in which the contents of each block are titled as in the table of contents page, and this index page may be treated in the same manner as the table of contents page to select blocks.

Additionally, the screen/write control circuit 100
The functions 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.

(1) A user of a multi-item input device can arbitrarily create or modify a display data file.

(2) When creating or modifying a display data file, characters are entered by specifying the characters actually displayed, so creating or modifying a display data file can be done easily and without error.

(3) Because text pages and data items are specified by specifying the display position on the screen rather than the display content itself, even if the contents of the display data file are changed as described above, the conventional book Unlike formula- or key-type multi-item input devices, there is no need to change or replace entries in books or key tops, making maintenance and management extremely easy, and also making it easy to create and modify display data files.

(4) Since the table of contents page can be displayed and the titles indicating the contents of a large number of body pages can be listed, the necessary body page can be easily and quickly selected, and data input operability 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 device can be made cheaper than when a light pen is used, and the operability can be greatly improved compared to when a switch is used.
