JPS5913779B2 - 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-powered devices include kanji teletype devices and tablet devices that use a pen to indicate characters, but both require a monitor display device to confirm the input characters.

However, CR can display kanji, kana, symbols, etc. as they are.
If a T display device is used, a high resolution is required, making the device expensive. Therefore, as shown in Figure 1, a method (see Japanese Patent Publication No. 52-23693) has been proposed in which the input kanji is broken down into kana characters by an encoder according to kun-yomi or on-yomi, and then displayed. has been done.

That is, as shown in FIG. 1a, kanji input from the keyboard 1 are encoded by the encoder 2 and recorded by the paper tape/punch device 3, and at the same time, in order to monitor the input kanji, the encoder 4 converts the kanji into kana characters. After decomposing the data into the following parts, the image shown in FIG. 1 is displayed on the display section T through the refresh memory 5 and the character generator 6 in kana sentences as shown in FIG. In Figure 1, from keyboard 1,
This is the display when "Please use black ink." is input, and all kanji are broken down into kana characters. When displaying kanji, 16 x 18 dots to 32 x 32 dots are required, and since there are many types of kanji, it is necessary to have a high-resolution CRT and a large capacity pattern memory. , symbols, etc., 5×7 dots to 7×9 dots are sufficient, and since the number of types of characters is small, the device is inexpensive.

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

Therefore, the inventor of the present invention previously proposed a device (see Japanese Patent Application No. 165790/1983) that displays kana characters in reverse display or with marks added depending on the type of character. By the way, in the Japanese human-powered device, instead of the visual typing method using the German key, there are two keys for Katakana, English letters, and codes only.
A touch method is used to input Japanese characters such as kanji, hiragana, and katakana by typing combinations.With this method, once you have memorized the combination code attached to each character, you can input it at the same speed as an English typewriter. (For example, see Japanese Patent Publication No. 50-35453).

When using this type of code input method and displaying it on a monitor on a conventional display device, it has the disadvantage that it is very difficult to see unless a code is attached to distinguish between codes. If it is the second character while inputting, another character will be specified for that part, resulting in an input error.

The purpose of the present invention is to solve such problems by using a CRT display device that can display katakana, English characters, and codes, and by making it easy to detect errors in inputting two-stroke codes, thereby reducing the mental burden on operators. An object of the present invention is to provide a character display method for a Japanese human-powered device, which can reduce the amount of stress and improve work efficiency.

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

FIG. 2 is a block diagram of a character display device according to the present invention, and FIG. 3 is an operation flow chart of FIG. The Japanese human power device 11 specifies kanji, katakana, hiragana, and various codes by inputting a two-stroke code as described above, and the code signal (8
A line that sends bits) C, to the display device 15 of the present invention, and a code signal (16
A line that converts the data into C2 (bit) and sends it to the information processing device 20 that processes the kanji characters is connected.

In the present invention, a display device 15 for displaying katakana, alphanumeric characters, and codes, a microcomputer control section 12, a memory 13 for storing programs, and a memory 14 for storing work data are connected.

The display device 15 includes a code refresh memory, a character generator, and a CRT display unit for displaying katakana and the like in 5×7 bits to 7×9 bits.

For example, to input the kanji for "black", the operator must
When you press the "K" key, the 8-bit code "C"
1 is sent to the display device 15 under the control of the control section 12.

The control unit 12 executes the program read from the program memory 13, thereby achieving stage 22 in FIG.
The presence or absence of a key input is determined at stage 23, the key input of the code "ku" is detected, and the key input character "ku" is displayed at stage 23. Next, when the operator presses the "wo" key, the 8-bit code C of "wo" is sent to the display device 15 under the control of the control section 12. The control unit 12 determines whether the second character of the code has been sent at stage 24, and
When the key input of ``wo'' is detected, the key input character of ``wo'' and the delimiter are displayed in stage 25, and the process proceeds to stage 2.
Return to step 2 and wait for the next character to be input. Note that the delimiter is
An 8-bit code indicating this is stored in data memory 14 or program memory 13, and by executing the subroutine of stage 25, it is read out and sent to display device 15 for display. Fourth
} This is a correspondence diagram of the characters and codes of the Japanese human-powered device in FIG. 2, and FIG. 5 is an explanatory diagram showing input sentences and display examples from the Japanese human-powered device.

All characters and codes used in Japanese writing, such as kanji, hiragana, katakana, and codes, are encoded with the two katakana characters displayed on the key, and part of the correspondence table is shown in Figure 4. It is shown. Approximately 2,000 kanji, etc., are encoded by a combination of two katakana characters displayed on each of the 48 keys, of which approximately 700
If you memorize ~800 combination codes, you can quickly input ordinary sentences.

According to the code shown in FIG. 4, the Japanese language human power device 11 issues a message saying, ``Please use black ink,'' as shown in FIG. 5a, for example.

'', a display as shown in FIG. 5b is obtained on the CRT display screen of the display device 15. As shown in FIG. 5b, in the embodiment, a billot "." is not shown as a code to distinguish one chord from another, but the symbol can also be a comma "," or a hyphen "-". A semicolon “;” is also acceptable.

Furthermore, although FIG. 2 shows a case where a microcomputer is used as the control unit 12, it is also possible to configure it with wired logic, and it is also possible to use the internal memory or CPU of a minicomputer or large computer. Of course, it is also possible to do so.

As explained above, according to the present invention, a display device capable of displaying katakana is used without using an expensive kanji display device. Since it can be realized inexpensively and the operator remembers the code, input characters can be displayed as a code,
Moreover, by displaying delimiters between codes, errors in input characters can be easily detected, reducing operator fatigue and improving work efficiency.
