JPS5913778B2 - Character display method of Japanese text input device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character display system for a Japanese character input device, and more particularly to a display system for a kanji input device that encodes and inputs a combination of katakana characters.

Japanese human power devices include kanji teletype type and tablet type that stores all characters on the board and indicates their position with a pen, but both require a monitor display device to check the characters entered. It is.

However, using a CRT display device that can display all kanji, hiragana, katakana, symbols, etc. requires a high resolution CRT and a large capacity pattern memory.
Equipment becomes expensive. Therefore, conventionally, as shown in FIG. 1, kanji input from a keyboard 1 are encoded by an encoder 2 and recorded by a paper tape/punch device 3, and an encoder 4 is used to monitor the input kanji.
After decomposing into kana characters, refresh memory 5
, a method of displaying Figure 1 in katakana as shown in Figure 1 on the display unit 7 through the character generator 6
2-2369) has been proposed.

FIG. 1 shows the display when "Please use black ink" is input from the keyboard 1, and all kanji are broken down into kana characters. When displaying kanji,
Since 16 x 18 dots to 32 x 32 dots are required (V) and there are many types of kanji, it is necessary to have a high resolution CRT and large capacity pattern memory, which is expensive. When displaying kanji and symbols, 5 x 7
Since dots to 7×9 dots are sufficient and the number of types of characters is small, the above-mentioned device is unnecessary and the device is inexpensive.

However, with the display method shown in FIG. 1, it is impossible to distinguish between kanji and kana, hiragana and katakana, and the layout of sentences cannot be distinguished.

Therefore, the inventor of the present invention previously proposed a device (see Japanese Patent Application No. 165790/1983) that displays characters in reverse or in kana characters with marks added, depending on the type of character. By the way, in Japanese human-powered machines, instead of the visual typing method using a single key, there is a touch method that inputs all the characters used in one Japanese sentence, such as kanji, hiragana, and katakana, using a combination of two key strokes for katakana, English letters, and codes. In this method, once you memorize the combination code attached to each character, you can input at the same speed as an English typewriter (for example, see Japanese Patent Publication No. 50-35453).

However, if this code input method were to display input characters in katakana as in the past, it would be difficult to read unless a code was added to distinguish the codes. If you are inputting what you thought was the first character, but it is the second character, another character will be identified for that part, causing an input error.

In addition, it is difficult to determine at a glance what kind of characters have been input from the list of characters that constitute the key-input code. An object of the present invention is to eliminate such drawbacks by using an inexpensive CRT display device that can display only katakana, hiragana, }, and symbols.
In order to make it easier to find typographical code input errors, we have made it easy to distinguish between kanji, katakana, and hiragana.
An object of the present invention is to provide a character display method for a Japanese human-powered device that can reduce the burden on an operator and improve work efficiency.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing an input sentence and a display example according to the present invention.
, FIG. 3 is a correspondence diagram of characters and codes of the Japanese human power device used in the present invention. In the Japanese writing device of the present invention, kanji, katakana, hiragana,
All characters and codes, such as codes, are coded by two combinations of katakana characters displayed on the keys, and a part of the correspondence table is shown in FIG.

In other words, about 2,000 kanji, etc. are encoded by two combinations of katakana, English letters, and codes displayed on each of the 48 keys} V1 Normally, about 700 of them
If you memorize ~800 combination codes, you can input sentences quickly. In the present invention, for example, please use black ink as shown in FIG. 2a.

", the kanji code is displayed with a mark (for example, an umlaut "...") on the code, and the katakana, hiragana, and code codes are displayed with a mark on each character, as shown in Figure 2b. converted and displayed. In Figure 2b,
Other than kanji, it is easy to monitor because it is the same as the normal display, and kanji are displayed as they are, so you can identify input errors, and katakana is marked with a sign to confirm that it is a kanji. can be distinguished at a glance.
Furthermore, since the displayed characters are only katakana, hiragana, and codes, it can be realized using an inexpensive CRT display device.
Katakana can be sufficiently expressed with a pattern configuration of 5 x 7 dots, and Hiragana can be sufficiently expressed with a pattern configuration of 10 x 10 dots, and since there are far fewer types of characters than Kanji, the pattern memory does not require a large capacity. FIG. 4 is a plotter diagram of the character display system of the Japanese human-powered device according to the present invention.

The character display system of the present invention is composed of a Japanese character display device 11, a display device 18, a memory, and a microcomputer, and can be realized at an extremely low cost.

That is, the control section 12 of the microcomputer, the program memory (ROM-A) 13, the katakana code table memory (ROM-B) 14, and the hiragana code table memory (ROM-B) 14.
- code table memory (ROM-C) 15, marked katakana code table memory (ROM-D) 16
, a working data memory 17, and a display device 18. Of course, it is also possible to integrate the memories 13-17 into one memory. Here, display device 1
8 displays only katakana, hiragana, and symbols,
A 10x10 bit pattern character generator, a CRT display, and a code refresher.
Equipped with memory. The Japanese human power device 11 is an information processing device-2 that has a built-in code conversion unit and performs V1 kanji processing.
In order to input a character into 0, a signal (8 bits) C1 coded by a combination of two katakana strokes is converted into a code signal (16 bits) C2 assigned to a kanji character and then sent.

On the other hand, the code input signal (8 bits) C1 is sent as is to the control section 12 for display on the monitor. Figure 5 A, b
, c is the katakana code table in Figure 4.
FIG. 6 is an explanatory diagram of table contents of memory, hiragana code table memory, and marked katakana code table memory. FIG. 6 is a processing flow chart of FIG. 4.

By executing the program read from the program memory 3, the control unit 12 first determines whether or not there is a key input at stage 22. For example, if the user presses the "ku" key to input the kanji character "kuro" on the Japanese human resource device 11, an 8-bit code for "ku" is sent to the control unit 12. When the control unit 12 detects the key input of the code [ku], the first character of the code is determined at stage 23, and this code is stored in the data memory 17 at stage 25. Next, when the code "wo" is sent from the Japanese human power device 11, the second character of the code is determined at stage 23, and the first character stored in the data memo January 7th is determined at stage 24. Read and search for the input code [kuwo] in the katakana code table memory 14 along with the second character. When it is determined in stage 26 that "kuwo" is not in the katakana code table, stage 27 converts the input code "kuwo" into hiragana code table memory 1.
Search by 5. At stage 29, it is found that "kuwo" is not found in the hiragana code table either, and when it is determined that it is a kanji code, at stage 50, the marked katakana code table memory 16 is searched for "kuwo". As shown in FIG. 5c, the table in the memory 16 stores characters constituting a code and marked characters in correspondence, so ``kuwo'' is searched for individually and converted into a signed character.

At the stage 30, the marked characters are simultaneously sent to the display device 18 for display.

Return to stage 22 and wait for the next input code. next,
In order to input the katakana character "i" from the Japanese human power device 11, an 8-bit code for "tsu" is sent to the control section 12, and the control section 12 determines the first character of the code at stage 23. At stage 25, this "tsu" code is stored in the data memory 7.

Next, when the code “I” is sent, stage 23
The second sentence of the code is determined, and in stage 24, the input code [Tweet] is searched for in katakana, code, table, memo 1 river 4.

In the katakana code table memory 14, as shown in FIG. When a match is detected, the katakana code [i] corresponding to the code "tsutsui" is read out at stage 28, and the display device 1
8 and displayed.

In this way, after inputting and displaying ``Please use black ink'', the 8-bit code for ``Yu'' is input in the hiragana character ``I'', so the 8-bit code for ``Yu'' is
1 is sent to the control unit 12, the first character of the code is determined at stage 23 and stored, and then the 8-bit code of "I" that is sent subsequently is detected and the code is sent to stage 24. Search for the code for "Thai" in Katakana Code Table Memory 14.

When it is determined at stage 26 that there is no code for "Thai" in this table, the code for "Thai" is then searched for in the hiragana code table memory 15 at stage 27.

The hiragana code table memory 15 stores the code "Thai" and the hiragana "i" as shown in FIG. " are compared, and if a match is detected, the hiragana character "i" corresponding to this code is read out at stage 31 and displayed on display device 18.

FIG. 7 shows a marked katakana letter illustrating another embodiment of the invention.
FIG. 3 is a storage state diagram of a code table memory.

In the display system shown in FIG. 1 (see Japanese Patent Publication No. 52-23693), input kanji characters are broken down into katakana or hiragana characters according to kun or onyomi and displayed.

However, this makes it difficult to determine whether kanji or katakana are being input. Therefore, it is easier to distinguish the kanji characters by displaying them in katakana or hiragana with marks. In addition, in the code input method, ease of typing and memorization of the code are important, but since only one code is allowed, the kanji ``black'' used in the input sentence The code is not necessarily "black". Therefore, as shown in Figure 7, a table for converting kanji codes to kanji sounds or kun readings is stored in ROM, and by converting input kanji codes to readings, sentences whose meanings can be easily determined are created. .

Furthermore, a mark indicating that it is a kanji is added to the display. For example, when "black ink..." is input, "I/sweet ink..." is displayed. In Fig. 4, a microcomputer is used as the control unit 12, but it may of course be configured with wired logic, or the memory and CPU built into a minicomputer or large computer may be used. You can also. As explained above, according to the present invention, it is possible to monitor the input characters of a Japanese human-powered device using an inexpensive display device that has character patterns of only katakana, hiragana, and codes, and it is possible to monitor characters inputted to a Japanese human-powered device using character patterns other than kanji. In addition to displaying kanji, kanji are displayed with marked input codes, sounds, and kun readings, making it easy to detect mistakes in entered characters, reducing input errors, improving work efficiency, and reducing fatigue. is possible.
