〔Example〕

 Hereinafter, the present invention will be described with reference to the drawings.

1 to 7 are views showing an embodiment of a multi-item input device according to the present invention. FIG. 1 is an overall configuration diagram of an information processing system to which the present device is applied. In FIG. 1, 1 is a multi-item input device. The multi-item input device 1 is a device in which an operator inputs character string data of a large number of items prepared in advance with one touch, and outputs it as a data signal to the host device 2. The host device 2 is the center of the information processing system, includes a processor such as a CPU, and executes various arithmetic processes based on input data from the multi-item input device 1, and the result is displayed by the display device 3 (for example, CRT),
Alternatively, it may be printed out by the output device 4 such as a printer. Further, a storage device 5 is connected to the host device 2, and the storage device 5 stores a large amount of data necessary for arithmetic processing.

The multi-item input device 1 includes a transparent input panel (corresponding to an input section) 6 and a plasma display (PD) as shown in FIG.
P) is integrated with the display device 7, and although not shown in FIG.
It is provided with a control unit 8 having a U and the like and a storage unit 9. The input panel 6 detects the data input for each item by pressing the item displayed on the display screen of the display device 7 with one touch, and outputs a signal to the input control circuit 30 described later. As shown in FIG. 3, transparent electrodes are deposited on each of the transparent sheet and the glass in strips, and X electrodes 11 and Y electrodes 12 are arranged so that the electrodes face each other at right angles. The data input is detected from the specified position.

The display device 7 uses a PDP with 640 (horizontal) x 480 (vertical) dots in order to handle the situation that the page switching speed is high, the viewing angle is wide, and clear item display can be obtained. The content of is displayed for each item on the PDP which is a display screen. As shown in FIG. 4, the display screen of the display device 7 is divided into 8 × 10 (m = 8, n = 10) frames, and one grid (frame) 13 has eight 16-dot Chinese characters ( l =
An area where 8) can be expressed is set as an item frame, and one item is stored in the storage unit 9 as 16-byte (2 × l = 16) Kanji code data. However, the expression of one item may require more than 8 characters. In such a case, the size of the item frame should be set to the size of the basic item frame (8 kanji characters) in order to obtain the freedom of item expression. It is a system that can be freely defined as an integral multiple area. Specifically, 1
The data for one item is composed of character code data necessary for item expression, 1-byte data indicating the vertical and horizontal sizes of the item frame, and 1-byte data indicating the display position of the item.

Next, the hardware circuit block of the multi-item input device 1 is shown in FIG. 5, and the multi-item input device 1 includes a main body 14 in which the input panel 6 and the display device 7 are integrated, and the input panel 6. The control unit 8 selects an item from the storage unit 9 according to the detection result and outputs it to the external host device 2, and the storage unit 9 stores data for each item. The storage unit 9 stores, as display data, a firmware ROM 21 that stores a processing program for the CPU 26, which will be described later, a character ROM 22 that stores font data (dot data) for Kanji data, and item data that is an input target. Display data RAM23 (eg 128K bytes SRAM) and CPU26
Is composed of a work RAM 24 for storing various kinds of calculation data necessary for executing calculation processing and a replaceable memory card 25 storing the same data as the display data RAM 23. The memory card 25 is used as a so-called auxiliary memory and, for example, 128 Kbytes are used so that the item display can be easily changed and added together with the display data RAM 23.

The control unit 8 includes a CPU 26, a PDP controller 27, a VRAM (video
RAM) 28, PDP interface circuit 29, input control circuit 30, sub CPU 31, and serial interface circuit 32. The CPU 26 operates based on the program stored in the firmware ROM 21, and the PDP controller 2
7 sequentially transfers the contents of VRAM 28 to the display device 7 via the PDP interface circuit 29, and the display device 7 displays the item screen. At this time, the CPU 26 extracts the Kanji code from the display data RAM 23, converts it into the corresponding font data (dot data) of the character ROM 22 and outputs it to VR.
Rewrite the contents of AM28. The input control circuit 30 takes in the signal from the input panel 6, the sub CPU 31 scans the address of the input panel 6 through the input control circuit 30, and when the operator presses down the item, the address coordinate data (address) is sent to the CPU 26. (Corresponding to the data). In response to this, the CPU 26 adds display information to the coordinate data from the sub CPU 31, and sends it to the external host device 2 via the serial interface circuit 32 as multi-item input data.

In the above configuration, first, the operation of the CPU 26 causes the PDP controller 27 to sequentially transfer the contents of the VRAM 28 to the display device 7 via the PDP interface circuit 29, and the item screen is displayed. When the operator presses a desired item while looking at the display screen of the display device 7, the input control circuit 30 notifies the CPU 26 of the coordinate data of the input panel 6, whereby the CPU 26 changes the coordinate data from the sub CPU 31 to the desired item. Corresponding input information is added and sent as one of the multi-item input data to the host device 2 via the serial interface circuit 32. In this case, the item data is stored in the display data RAM 23, but the display format is set as follows. First, as shown in FIG. 4, the display area is divided into 8 × 10 grids as a basic unit, and the sizes of items are the following four types.

i) Frame 1 (1 grid, basic frame) Up to 4 full-width characters x 2 lines, half-width characters 9 characters x 2
Up to the line.

ii) Box 2 (horizontal double of box 1) Full-width characters up to 9 characters x 2 lines, Half-width characters up to 19 characters x 2
Up to the line.

iii) Box 3 (vertical double of box 1) Full-width characters are up to 4 characters x 4 lines, Half-width characters are up to 9 characters x 4
Up to the line.

iv) Frame 4 (horizontal and vertical multiplication of frame 1) Full-width characters up to 9 characters x 4 lines, half-width characters up to 19 characters x 4
Up to the line.

A display-only area (area without an item frame) is treated as a rectangular area as a basic unit and managed as an integral multiple of the basic grid. The number of displayed characters is limited by the number of basic grids, and one basic grid has 5 double-byte characters.
Character x 2 lines, half-width characters up to 10 characters x 2 lines can be displayed. Of the display data formats, the page data internal format is shown as in FIG. 6, and FD in the figure represents the end of data. In addition, the data format in one item is shown as in Fig. 7. In the figure, the item coordinate data shows the position by item No. When the item frame is double horizontal and vertical double, it is shown by the code in the upper left grid. Be done. The data attributes are as follows.

Frame 1 80 Frame 2 90 Frame 3 A0 Frame 4 B0 Character display only C0 + area information (1 byte) In the area information, the upper 4 bits are the number of grids in the Y direction,
The lower 4 bits are the number of grids in the X direction.

The character code is half-width character: JIS code (1 byte) full-width character: shift JIS code (2 bytes). When enlarging and displaying a full-width character, the following 1 byte is added before the 2-byte code.

Horizontal 01 Vertical double 02 Vertical horizontal 03 The character code storage order is as shown in the table below.

However, 1 to 18 are each one item in the figure, OF is a terminator and is stored at the end of item data.

Here, considering the effect on the conventional device, for example, if the display data is stored as bit image data corresponding to each dot of the PDP in the display device 7, the display screen can be freely changed, but as an item key. A huge memory (for example, 2.5 Mbytes) is required to store the required 64 pages of data.

Therefore, in the present embodiment, the item display of the item key is generally expressed by characters, so that the item display data of each page is stored as a character code and the display screen is 8 ×.
It is divided into 10 frames, and the area where 8 characters of 16-dot kanji can be expressed in one frame is defined as a basic item frame, and one item is stored as 16-byte Kanji code data.
In addition, the expression of one item may require more than eight characters, so that the size of the item frame can be freely defined as a rectangular area that is an integral multiple of the basic item frame (eight characters for Chinese characters).
FIG. 4 shows a specific example thereof. For example, the address of item A is (3,4) corresponding to the basic item frame, but the size of the area (X, Y) exceeds the basic item frame ( 3,2) and it is getting bigger. Items B and C are also designated by a large rectangle. This gives you the flexibility to limit the number of characters required to display items, and allows you to store 64 pages of data in 93K bytes of memory. Can be realized. Also, the size of the displayed items can be freely changed,
The number of items can be changed and expanded easily, and the page switching speed can be increased. Further, the display content is held as data, the content changes on the screen of the display device 7 made of PDP, and the writing of the display content may be stored in the display data RAM 23. Therefore, the man-hours for writing the data contents are reduced and it becomes easy.

Further, since the memory card 25 is used in the present embodiment, there is an advantage that item display can be changed and added very easily. Furthermore, since the display address data is stored in the item data, the order between the item data can be freely changed.

The display device 7 is not limited to the PDP and may be a liquid crystal display (LCD).

〔The invention's effect〕

According to the present invention, it is possible to easily write the data content and reduce the man-hour, and it is possible to easily change and expand the number of items and speed up page switching. Further, the required memory capacity is small, and the cost can be reduced and the size can be reduced.
