JPS5913776B2 - 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 the characters on the board and indicates the position with a pen.
In either case, a monitor display device is required to confirm the entered characters.

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 at the same time, in order to monitor the input kanji, an encoder 4 is used to encode kana characters. A method has been proposed (see Japanese Patent Publication No. 52-23693) in which the image is decomposed into 2 and then displayed in katakana as shown in FIG. 1 on the display unit 7 through the refresh memory 5 and character generator 6.

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, and there are many types of kanji, a high-resolution CRT and large-capacity pattern memory must be installed, which is expensive. , when displaying the sign, 5×7
Since dots to 7×9 dots are sufficient and the number of types of characters is small, the above device is not required 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, etc., and the layout of sentences cannot be determined.

Therefore, the inventor of the present invention first developed a method for displaying inverted display depending on the type of character. Or a device that displays kana characters with marks added (
(See the specification of Japanese Patent Application No. 165790/1983).
By the way, in the Japanese human-powered device, instead of the visual typing method using a single key, a touch method is used to input all characters such as kanji, hiragana, and katakana used in Japanese text using a combination of two strokes of katakana, English character, and code keys. is used, and in this system, once the combination code attached to each character is memorized, input can be made at the same speed as an English typewriter (see, for example, Japanese Patent Publication No. 50-35453).

However, a problem with this type of code input method is that when input characters are displayed in katakana as in the past, it is very difficult to read unless a code is attached to distinguish between codes. If you are inputting what you thought was the first character, but it is the second character, another character will be specified for that part, resulting in an input error.

The purpose of the present invention is to eliminate such drawbacks by using a CRT display device that can display katakana characters, English characters, and codes, thereby making it easier to detect errors in inputting two-stroke codes, thereby reducing the mental burden on operators. At the same time, it helps to clearly distinguish between kanji, hiragana, and katakana.
An object of the present invention is to provide a character display method for a Japanese human-powered device that can improve work efficiency.

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

FIG. 2 is a diagram showing a display example according to the present invention;
The figure 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, all characters and codes used in Japanese writing, such as kanji, hiragana, katakana, and codes, are encoded by two combinations of katakana characters displayed on the keys, and a corresponding table is provided. A part of it is shown in FIG.

In other words, approximately 2,000 kanji and other characters are coded by combinations of two katakana characters displayed on 48 keys, and if you memorize approximately 700 to 800 of these combination codes, you can quickly read ordinary sentences. can be entered. In a first embodiment of the display according to the present invention, as shown in FIG. 2a, "Please use black ink X.'o"
In response to the input, kanji are displayed using the code shown in FIG. 3, hiragana and katakana are displayed using only the second character of the code shown in FIG. 3, and a delimiter is displayed for each code or character.

As is clear from FIG. 3, in the combination code of hiragana and katakana, the second character always matches the corresponding character, and the first character is a shift character.

Therefore, when displaying hiragana and katakana, the second
It is easier to distinguish if only the letters are displayed. Figure 2b shows a display method showing the second embodiment. In this case, as in Figure 2a, kanji are displayed as codes, and hiragana and katakana are displayed only as the second character of the code. However, the delimiter is displayed each time the character type changes: kanji, hiragana, and yotakana.

FIG. 2c shows a display method showing a third embodiment, and in this case is a modification of FIG. 2a. In order to distinguish between hiragana and katakana in the display of FIG. Add an IO (umlaut) symbol to something.

FIG. 2 d shows a display method showing a fourth embodiment, and in this case is a modification of FIG. 2 b. In order to distinguish between hiragana and katakana in the display of FIG. Add a 00 (umlaut) sign.

FIG. 2e shows a display method showing a fifth embodiment, which is a modification of FIG. 2d, in which the delimiter between hiragana and katakana is removed.

That is, delimiters are displayed only between kanji and kana characters, and umlauts are used to distinguish between hiragana and katakana. FIG. 4 is a block diagram of a character display method according to the present invention.

The Japanese human power device 11 specifies kanji, hiragana, katakana, and various codes by specifying a code using a combination of two strokes of katakana as described above, and performs C2IIC conversion of the code signal (16 bits) of the kanji, etc. specified by the code. The code signal (8) of the character displayed on the key is sent to the information processing device 20 for kanji processing.
Bit) C is sent to the display device 17 under the control of the control section 12, thereby causing the input character to be displayed on the monitor.

The character display method according to the present invention includes a display device 17 that displays katakana, alphabetic characters, and codes, a control section 12 of a microcomputer, and a memory (ROM-ROM) that stores programs.
A) 13 and Katakana code table memory (R
OM-B) 14, hiragana code table memory (ROM-C) 15, and work data/memo] Kawa 6
is connected. The display device 17 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.

5 is a table explanatory diagram of the katakana code table memory and hiragana code table memory in FIG. 4, and FIG. 6 is a table explanatory diagram of the processing operation flow in FIG. 4.
It's a chat.

Note that FIG. 6 shows the display operation of the third embodiment shown in FIG. 2c.

By executing the program read from the program memory 13, the control unit 12 first determines whether or not there is a key input at the stage 22.

For example, if you press the ``ku'' key to input the kanji for ``kuro'' on the Japanese human power device 11, the 8-pits key for ``ku'' will appear.
The code is sent to the control unit 12. When the control unit 12
When a key input of the code is detected, the first character of the code is determined at stage 23, and this code is stored in the data memory 16 at stage 25. Next, when the code for "A" is sent from the Japanese human power device 11, the second character of the code is determined at stage 23, and the data memory 1 is stored at stage 24.
Read out the first character stored in 6 and input the input code ``Kuwo'' along with the second character into the katakana code table.
Search in memory 14. In stage 26, if it is determined that there is no "kura" in the katakana code table, in stage 27 the input code "kura" is converted into hiragana code.
Search in table memory 15. At stage 29, it is found that there is no "kura" in the hiragana code table, it is determined that it is a kanji code, and at stage 30, the input code "kura" is displayed as is, and then at stage 32
to display the delimiter. Then, the process returns to stage 22 and waits for the next input code. Note that an 8-bit code indicating the delimiter is stored in the data memory 16 or program memory 13, and by executing the subroutine of stage 32, this code is read out and displayed on the display device 17. will be sent to. Next, in order to input the katakana "i" from the Japanese human power device 11, "
When the 8-bit code for ``tsu'' is sent to the control section 12, the control section 12 determines the first character of the code at stage 23, and at stage 25 stores this 8-bit code for ``tsu'' in the data memo I river 6. Remember.

Next, when the code "I" is sent, stage 23
The second character of the code is determined at stage 24, and the input code "Tsui" is searched for in the katakana code table memory 14. As shown in FIG. 5a, the katakana code table memory 14VC stores the code "tsui" and the katakana code "i" corresponding to this code.
At stage 26, the input code and the table code are compared, and if a match is detected, at stage 28, the katakana code "i" corresponding to the code "tsui" is read out and sent to the display device 17 for display. . Furthermore, stage 3
After the delimiter is displayed at 2, the process returns to stage 22VC. After sequentially displaying the input characters in this way, in order to input the hiragana ``i'', the 8-bit code for ``Yu'' is sent from the Japanese human power device 11 to the control unit 12, and at stage 23 the code 1 After identifying the letters and memorizing them,
Subsequently, the sent 8-bit code for "I" is detected, and in stage 24 the code for "Thai" is searched in the katakana code table memory 14.

If it is determined that the code is not in this table, then in stage 27 the hiragana code table memory 15 is searched for the code for "Thai".

As shown in FIG. 5b, the hiragana code table memory 15 stores the code "Thai" and the marked katakana code "i1" corresponding to this code, and the input code "i1" is stored in the stage 29. Tie” and table code “
"Ties" are compared and if a match is found, stage 31
The marked katakana code corresponding to this code is read out and displayed.

Furthermore, after the delimiter is displayed at stage 32, the process returns to stage 22. FIG. 7 is a flowchart of the processing operation of FIG. 4, and shows the display operation of the fifth embodiment shown in FIG. 2e.

In this case, as shown in FIG. 2e, no delimiter is displayed between hiragana and katakana, so it is necessary to insert a subroutine to determine whether a delimiter is to be displayed.

That is, a stage 33 for temporarily storing the type of displayed character in the data memory 16 is provided next to stages 26 and 29 in FIG. 6, and the previously stored character type and the current character type are compared. A stage 34 is provided for determining whether or not to display a delimiter. At the same time as displaying kanji, hiragana, and katakana, the previously displayed character type is moved from the current area to the past area in the data memory 16, and the character type just displayed is stored in the current area. In stage 33, if the pattern in the past/present area of the data memory 16 is "Kanji/Kana" or "Kana/Kana", then "Kana/Kanji" is displayed without displaying the delimiter. If so, determine whether to display delimiters before and after the kanji. In addition to the period ".", a comma ",", a hyphen "-", a semicolon ";", etc. may be displayed as the delimiter.

Furthermore, although FIG. 4 shows the 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, input characters can be displayed in codes and katakana, and kanji, hiragana, and katakana can be distinguished, so errors in input characters can be easily discovered, and operator fatigue can be reduced. This can improve work efficiency.
