[Industrial application field]

The present invention relates to a character display processing device that is added to a display panel that receives character information output from a character display processor and displays the character.

In word processors and the like, documents are created by displaying standardized characters on a display panel based on character information output from a character display processor. The characters mentioned here include kana characters, katakana characters, kanji characters, alphabetic characters, numbers, etc. Additionally, devices that handle such characters are not limited to the word processors mentioned above, but also include personal computers and workstations.

The present invention describes a word processor, a personal computer, a workstation, etc., which are equipped with a display panel such as a liquid crystal display and input means for the display panel.

[Conventional technology]

In the above-mentioned word processor, etc., a processor for character display, a display panel that receives character information output from this processor and displays the character, and a character to be displayed on the display panel is specified via the processor. A so-called keyboard is an essential component.

The keyboard has not only keys for specifying characters, but also function keys for specifying various functions.

[Problem to be solved by the invention]

Although the above-mentioned word processors are equipped with at least a keyboard, there is a well-known problem that the keyboard is not easy to operate.

That is, when used by a person who is not accustomed to keyboard operations, since he or she is not familiar with the key arrangement, it takes time to input data, resulting in poor operability. In addition, since the display panel and keyboard are separated, when performing keystrokes, the line of sight first shifts to the hand, then to the display panel to view the human-powered character, which not only causes eye fatigue. , the operation time will be longer.

Furthermore, in current keyboards, one key has multiple meanings, so the meaning changes depending on the operation or application program. In particular, on keyboards compatible with Japanese, each key has three to five different meanings, making it difficult to confirm the meaning of the key.

On the other hand, handwriting input devices are known as devices that can improve the above-mentioned operability, but current handwriting input devices do not have a key interface, so when connecting to an existing device, it is necessary to create a new handwriting input device. It is not easy to use, as it requires additional interface cards and programs to be added to the application.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a character display processing device that can further improve operability.

[Means to solve the problem]

FIG. 1 is a block diagram showing the basic configuration of the present invention. In the figure, 20 is a character display processing device, which is added to the display panel 11 that receives character information CI output from a character display processor 10 and displays the character.

Reference numeral 21 denotes a touch panel, which is provided overlappingly on the display panel 11, allows characters on the display panel 11 to pass through, and electrically reads characters input by hand to be displayed on the display panel 11. Note that, for ease of understanding, the display panel 11 and the touch panel 21 are shown offset from each other in the figure.

22 is a touch panel input recognition unit that identifies handwritten characters read from the touch panel 21.

23 is a code conversion unit that converts the identified handwritten characters into a code CD that can be recognized by the processor 10.

A character corresponding to the handwritten character is thus output from the processor 10 to the display panel 11 as character information CI.

More preferably, a function display area 31 for displaying various functions (Fl, F2, F3, F4) is provided in a part of the display panel 11, and by touching the corresponding function display on the touch panel 21, the touch panel input can be identified. The function is identified in the section 22, converted into a corresponding code CD in the code conversion section 23, and inputted to the processor 10.

Furthermore, preferably, a character display area 41 is provided in a part of the display panel 11 to display the character identified by the touch panel input identification section 22, so that the character displayed in the character display area 41 is correctly identified. In order to confirm that the corresponding function 1 in the function display area 31 (for example, F4
) is touched on the touch panel 21, and the touch is received via the line 42 to drive the code conversion section 23.

[For production]

As described above, according to the present invention, the conventional keyboard is completely eliminated, improving operability. In place of this eliminated keyboard, a touch panel 21 is installed on the display panel 11.
are provided one on top of the other, and by touching this touch panel 21, it has a function equivalent to a conventional keyboard. For this purpose, a touch panel input identification section 22 and a code conversion section 23 are provided.

〔Example〕

FIG. 2 is a circuit diagram showing an embodiment of the present invention, especially the first embodiment.
The character display processing device 20 shown in the figure is shown in detail. In addition,
Portions corresponding to those in FIG. 1 are designated with the same reference numbers or symbols.

The touch panel 21 overlaid on the display panel 11 is a so-called digitizer, and is made of, for example, transparent electrodes arranged in a matrix in the X and Y directions.

The X-Y coordinate signal thus read from the dataizer (21) is applied to the touch panel input section 51, where CP[
I52 is converted into an decipherable digital signal.

CPII 52 cooperates with ROM 53 and RAM 54. RO! , 153 store a control program for the CPU 52, and a RAM 54 temporarily stores processing data. Particularly important programs in ROM53 are:
Signals from the touch panel input unit 51 (for example, handwritten characters “A”, “5”, etc. and function F1)
This is a program for decoding ~F4). Note that the functions F1 to F4 are, for example, "conversion", "copy",
There are "movement", "selection", etc.

The contents of characters and functions decoded by the decoding program in the RUM 53 are temporarily stored in the RAM 54. Among these, the characters are first displayed in the character display area 41 provided in a part of the display panel 11 via the display control section 56 and the composition section 57.

Here, the handwritten character intended by the operator and the CP
A match is made with the character deciphered (identified) by U 52. If these match, the operator displays the display panel 1.
1, touch the part on the touch panel 21 corresponding to function F4 ("selection") to proceed with the process further. That is, the keyboard interface 55 converts it into a code CD that can be processed by the processor 10. for example,
The kana character “he” is input by hand, and the “select” (
confirmation) is performed, the code “3E” corresponding to “to” is
"" is output from the keyboard interface 55 forming the code converter 23.

The display control unit 56 displays the above “he” identified by the CP (152) in the character display area 4I in the display panel 11. In this case, the output of the display control unit 56 is transmitted via the synthesis unit 57. The character information C from the processor 10 is provided to the display panel 11.
I and the output from the display control unit 56 are alternatively combined and provided to the display panel 11. This is, so to speak, a multiplex section.

Reference numeral 61 in FIG. 2 indicates an IC card interface, which is an option, and when special codes are handled, an IC card with a built-in dedicated conversion table is used instead.

This allows it to accommodate all types of characters.

FIG. 3 is a flowchart showing processing according to the present invention, and shows the above-mentioned operation in a flowchart.

Step a: The touch panel 21 waits for a touch input from the operator.

Step b: The operator touches the touch panel 21.

Step C: Is it a handwritten character input? (YES)
), whether functions F1 to F4 are performed manually (No
).

Step 62 If the handwritten character is handwritten, this is C
Identified by PU 52.

Step C: Code C corresponding to the handwritten character
D using the keyboard interface 55.

Step f: Output the code CD to the processor.

When it is determined in step g that a function has been specified in step C, the corresponding function is
52.

Step h: Convert the function into a corresponding code on the keyboard ink face 55.

FIG. 4 is a diagram showing an example of screen transitions on the display panel. This is the display panel 1 seen through the touch panel 21.
This is screen number 1.

State (a): The operator intends to display "round" in the underlined portion.

To do this, touch the touch panel 11 with your finger and write "maru". Note that the area where characters are handwritten is not specifically defined. This is because the degree of freedom increases.

State (b): “Maru” is displayed in the character display area 41. The area 41 is located at the lower right corner of the display panel 11 (
1 and 2), or may be formed while moving forward of documents created one after another like in a word processor. This figure shows an example of the latter.

State (C): Touch the part on the touch panel 21 corresponding to "conversion" in the function display area 31.

State (e): A “yen” converted by the processor 10 is displayed on the display panel 11. Furthermore, input “I.°” by hand.

State (f): The desired document is finally displayed.
