Description

[Detailed Description of the Invention] Technical Field The present invention relates to a Japanese language processing device, and more specifically, to converting kana characters in an input Japanese sentence from hiragana characters to katakana characters, or from hiragana characters to katakana characters as necessary. The present invention relates to a Japanese language processing device equipped with a hiragana-kana conversion function for converting kana characters into hiragana characters.

Background Art Japanese language processing devices are devices that have become rapidly popular in recent years as they enable quick and easy document creation and document management, and rationalization of office work.

Among Japanese language processing devices, for example, a kana-kanji conversion type converts a Japanese sentence inputted in kana characters from a keyboard into kana-kanji characters and displays the result on the screen. The editor can perform desired editing operations such as insertion, deletion, and correction while looking at the screen. The key date is the kana key and mode switching between hiragana and katakana (here, the mode is hiragana, katakana, kanji).

Refers to types such as alphabetic characters. ), and the operator can select hiragana input or katakana input by switching this kana mode specification key.

By the way, with conventional Japanese language processing devices, when inputting Japanese, the mode may be incorrectly selected for Hiragana or Katakana.
If you end up inputting in a mode different from the mode you were trying to input, even if you change the mode, it will only be effective for subsequent manual keystrokes, and the mode will not be changed for characters that have already been input. Therefore,
I had to either correct the Japanese input a bit or make corrections in later editing work.

On the other hand, corrections in editing work can only be processed character by character, so if there are multiple incorrectly entered characters in a row, you must individually move the cursor, operate the correction key, and input the character key to be corrected. This has to be done repeatedly, which is very inconvenient to operate and causes a decrease in work efficiency.

Purpose The present invention solves the drawbacks of the prior art, and allows you to read and write hiragana or katakana character strings that have already been input in one mode at a time while looking at the Japanese text displayed on the screen with simple key operations. An object of the present invention is to provide a Japanese language processing device with good operability and which can convert character strings into Katakana or Hiragana characters in the mode.

Configuration The configuration of the present invention will be described below based on one embodiment.

FIG. 1 is a block diagram showing an example of the configuration of a kana-kanji conversion type Japanese processing device according to the present invention.

In the same figure, the key? A Japanese language processing section 14- is connected to the card 10 via a key determination section 12. Key date 1
0 is character keys such as kana key, alphabet key, insert key,
It has various keys necessary for performing Japanese input operations, kana-kanji conversion, editing operations, etc., such as function keys such as a delete key and a correction key. When a key is pressed, code data corresponding to each key is output. It has become so. The Key Date 10 also has a katakana key, a shift key, a hiragana/katakana conversion key, and a cursor key. If you press the Kana key while the Katakana key is released, you can input hiragana characters, and if you press the Kana key while the Katakana key is pressed, you can input katakana characters manually. Japanese input is done in solid writing using kana characters. The hiragana/katakana conversion key is only used to instruct the mode conversion of kana characters that have already been input.
When pressed with the shift key released, it represents conversion from hiragana to katakana, and when the shift key is pressed, it represents conversion from katakana to hiragana. When the cursor key is operated, movement amount data is output to a Kahnle moving unit 16, which will be described later, and the cursor on the screen moves in the X or Y direction.

The key determination unit 12 has a function of determining whether input data from the keyboard 10 is a command related to a hiragana/katakana conversion key. The data is output as is to the word processing section 14. When a command related to the hiragana/katakana conversion key is input, a read signal is output to the cursor position storage section 18 connected to the output side.

The Japanese language processing unit 14 first converts the solid Japanese text sent from the keyboard 10 by the input operation of the operator into a memo IJ.
20 input row storage areas. When a punctuation mark or space is input, the Japanese processing unit 14 converts the solid Japanese sentence stored in the input line storage area into kana-kanji using a word dictionary and grammar rules, and stores it in the converted line storage area of the memory 20. A CRT control unit 22 and a CRT display 24 are connected to the output side of the memory 20, and the input sentence and converted sentence data stored in the memory 20 are converted into characters and characters.
The lines are changed every turn and displayed at predetermined input line display positions and conversion line display positions on the screen, respectively. C
The RT control unit 22 also displays a cursor on the screen based on cursor data sent from the cursor moving unit 16.

The Japanese language processing unit 14 also has an editing function for deleting, inserting, correcting, etc. the converted sentence. When the oirator operates the cursor keys on the keyboard 10 to specify a position in order to change the converted sentence displayed on the screen, the cursor moving part 16
The cursor data is manually inputted to the Japanese language processing section 14.

Also, when editing keys such as deletion, insertion, and correction keys (excluding hiragana/katakana conversion keys) and character keys necessary for changes are operated, the corresponding commands and character data are sent to the Japanese language processing section 14.

The Japanese language processing unit 14 reads out the converted sentences stored in the memory 20 based on the input editing commands, and performs deletion, insertion, correction, etc. to modify and change them.

The edited converted sentence is stored again in the converted line storage area of the memo I720 and displayed on the screen.

In addition, when the Japanese language processing device according to this configuration example is inputting Japanese using kana characters, if you want to correct the mode of the wrong hiragana character string or katakana character string that has already been input, By placing the cursor on the last character of the desired kana character string displayed on the input line of the screen and pressing the hiragana/katakana conversion key, you can go back and convert multiple characters at once.

Also, when editing, if you want to convert the mode of the hiragana character string or katakana character string displayed in the conversion property of the screen, you can use the first and last characters of the desired kana character string displayed in the conversion property of the screen. By placing the cursor on the cursor and pressing the hiragana/katakana conversion key, you can convert the kana character string in the section specified by the cursor at once.

That is, when the hiragana/katakana conversion key is pressed on the keyboard 10, the key determination unit 12 determines this and sends a read signal to the cursor position storage unit 18. Also, at this time,
If the shift key is pressed, the key determination unit 12
sends a shift signal indicating that the shift key is pressed to the hiragana/katakana conversion section 26 connected to the output side of the cursor position storage section 18.

The cursor position storage unit 18 has a function of storing a section of a kana character string to be converted into a mode.

When the first read signal is input, the cursor position memory section 1
8 reads the cursor data outputted by the cursor moving unit 16 at that time and stores it as first data. continue,
It is determined whether the cursor data is data related to the conversion line display area of the screen or data related to the input line display area, and if it is the former, it waits for the next read signal to be input from the key determination unit 12. Then, after moving the cursor by operating the cursor keys, when a second read signal is input by pressing the hiragana/katakana conversion key, the cursor position storage unit 18 again reads the second cursor data that the cursor movement unit 16 is outputting at that time. Remember. The first
．． The second cursor data represents the section of the kana character string for which mode conversion is desired in the conversion sentence.

Separately, when the cursor data input from the cursor moving unit 16 in response to the first read signal is data related to the input line display area of the screen, the cursor position storage unit 18 stores this data as the first cursor data. At the same time, a cursor backward signal is output to the cursor moving section 16.

The cursor moving unit 16 has a cursor data register, and when the user enters movement amount data in the X direction or the X direction from the keyboard 10 by operating the cursor keys, the cursor moving unit 16 adds or subtracts the data to the cursor data stored in the register to update the cursor data. . Further, when a cursor backward signal is input from the cursor position storage section 18, the cursor data stored in the register is sequentially decremented to move the cursor backward one character at a time. In this way, the vine data is retracted until a stop signal is input from the cursor position storage section 18. The cursor data stored in the cursor moving section 16 is sent to the CRT control section 2z to display a cursor on the screen, and is also sent to the cursor position storage section 18 during the mode conversion process for kana characters. Further, when decrementing is performed by inputting a cursor backward signal, cursor data is sent to a mode storage section 28 connected to the output side of the cursor moving section 16.

When the cursor data is input from the cursor moving unit 16, the mode storage unit 28 reads out character data at the address indicated by the cursor data from the memo 9200 human power running storage area and sets the character mode to hiragana (mode = 1) or 1.
(mode = 2). Then, set the mode of the character A related to the first cursor data specified by the operator before decrementing (the last character of the character string desired to be converted) to mode 'A (-1 or 2), and set each character during decrement to mode 'A (-1 or 2). Character modes related to cursor data are set in order: mode Bl + mode B2
*mode B3, stored as -(=1 or 2) and output to the mode determination unit 30 connected to the output side.

The mode determining unit 30 sequentially selects the mode storage unit 2 according to the decrement operation of the cursor data based on mode A.
modeBl sent from 8, modeB2+...
・Let's compare. The last character of the character string you want to convert will be a character in a different mode, mode A lol.
When the ode B4 is reached, a selection signal is output to the cursor position storage section 18. The cursor position storage unit 18, which has received this selection signal, inputs the cursor data that the cursor moving unit 16 is outputting at that time, increments it by ■, and stores it as second cursor data. However, even if you move the cursor back to the beginning of the input line, mode 'A %mo
When it is not deJ, the sentence start address is used as the second cursor data. As a result, if the last character position of the kana character string for which mode conversion of the input line is desired is specified, the first character position will be automatically selected.

A hiragana/katakana conversion section 26 is connected to the output side of the cursor position storage section 18. Cursor position storage unit 1
8 indicates the range after completing the selection of the section of the kana character string to be converted. The second cursor data is output to the hiragana/katakana converter 26. This hiragana/katakana converter 26 is connected to the memory 20, and the first . Kana character string data in the section represented by the second cursor data is read out, the mode is converted, and the data is stored in the memory 20 again.

However, the hiragana/katakana conversion section 26 is the key determination section 12.
When the /ft signal is input, the mode is converted from katakana to hiragana, and when the /ft signal is not input, the mode is converted from hiragana to katakana. The mode conversion process can be performed by adding and subtracting a certain number of codes, for example, by taking advantage of the fact that hiragana chords and katakana chords have a certain correspondence relationship.

The contents of the memory 20 whose kana character string mode has been corrected in this manner are immediately displayed on the screen of the CRT display 24. When the mode of the kana character string in the input line is corrected, the Japanese processing unit 1 is
Kana-kanji conversion is done in 4. Furthermore, when the mode of the kana character string in the conversion line is corrected, it is possible to subsequently perform message editing operations such as insertion and deletion.

Next, the overall operation of the above embodiment will be explained based on FIGS. 2 and 3. Figure 2 is a flowchart showing the operation when converting the mode of a kana character string in a converted sentence during editing, and Figure 3 is a flowchart showing the operation when converting the mode of a kana character string in an input sentence during input. .

First, the case of changing a hiragana character string in a converted sentence to a katakana character string will be described with reference to FIG. Without changing the mode, the operator operates the cursor keys while looking at the screen to move the cursor to the first character position of the hiragana character string for which mode conversion is desired in the conversion line. At this time, the cursor moving unit 16 outputs cursor data at the first character position to the cursor position storage unit 18. Next, with the shift key released, the hiragana/katakana conversion key is pressed to send the command to the key determination section 12.

This key determination unit 12 determines in advance whether or not there is human power to press the keys on the keyboard 10! 1) (50), when there is human power on the key, it is determined whether or not the hiragana/katakana conversion key is used 51), and when there is human power on other keys, the corresponding processing is performed in the Japanese processing unit 14 (52). If the hiragana/katakana conversion key is used, the key determination unit 12 outputs a read signal and causes the cursor position storage unit 18 to store the first cursor data output by the cursor movement unit 16 (53). Since the cursor data is data related to conversion, the cursor position storage unit 18 then determines whether the hiragana/katakana conversion key has been pressed twice.
), if no, return to the flow of whether key personnel are available (50)
. Here, when the operator places the cursor on the last character position of the hiragana character string that the operator desires to convert and presses the hiragana/katakana conversion key, the cursor moving unit 16 outputs the current value to the cursor position storage unit 18 in the same manner as described above. second cursor data is stored (53).

When the hiragana/katakana conversion key is pressed twice and the 19th M2 cursor data is stored in the cursor position R storage section 18, this data is sent to the hiragana/katakana conversion section 26. The hiragana/katakana converter 26 to which the shift signal is not input converts the hiragana character string data in the section indicated by the first and second cursor data in the conversion line storage area of the memory 20 into the corresponding katakana character string data. Do (55)
. The corrected converted sentence is displayed on the screen all at once. Next, the operator judges whether the mode conversion of all the Kana character strings in the conversion sentence has been completed. 56) When it has finished, the flow is ended, and if not, it returns to the beginning. Convert string mode. At this time, if you want to convert a katakana character string to a hiragana character string, you can press the shift key in advance.

In addition, by placing the cursor on the kana character in the conversion sentence and pressing the hiragana/katakana conversion key twice, you can convert the mode between the first cursor data and the second cursor data.

Next, with reference to FIG. 3, a case will be described in which a katakana character string that is erroneously input while inputting Japanese in the hiragana mode is corrected to a hiragana character string. 1st,
While looking at the screen, the operator operates the cursor keys to move the cursor to the last character position of the kana character string for which mode conversion is desired in the input sentence displayed in the input line display area. Next, hold down the shift key and type hiragana/
Press the katakana conversion key and send the specified command to key determination unit 1
Send to 2.

The key determination unit 12 determines in advance whether or not there is human power to press the keys on the keyboard 10 (13O), and if there is human power to key the keys, it further determines whether or not the keys are hiragana/katakana conversion keys 61). When the key is human power, the Japanese language processing section is made to perform the corresponding processing (62). Hiragana・
When it is based on a katakana conversion key, the key determination unit 1
2 outputs a shift signal to the hiragana/katakana conversion section 26 and a read signal to the cursor position storage section 18 to store the first cursor data output from the cursor movement section 16 (63). Since this cursor data is data related to the input line, the cursor position storage unit 18
sends a backward signal to the cursor moving unit 2o.

The cursor moving section 2o that has received the backward signal sends this cursor data to the mode storage section 22 before decrementing the cursor data.

The mode storage unit 22 identifies the mode of the kana character (here, the gatagana character) at the position indicated by the cursor data among the character data stored in the input line storage area of the memo I720.
It is stored as de A = 2 and sent to the mode determination section 24 (KC64).

On the other hand, the cursor position storage unit 18 receives information from the cursor movement unit 20 to determine whether the input cursor data is the beginning of the input line (65), and if it is the beginning of the sentence, the hiragana/katakana conversion unit converts the first cursor data to the second cursor data. 26. Hiragana inputting the shift signal
The katakana conversion unit 26 converts katakana characters in the memory 20 corresponding to the cursor data into hiragana characters (6
6).

Separately, when the cursor data input from the cursor moving unit 20 is not at the beginning of the input line, the cursor moving unit 20 moves the cursor back by one character (67) and sends the decremented cursor data to the mode storage unit 22. do.

The mode storage unit 22 identifies the mode of the kana character at the position indicated by the cursor data decremented by 1, and stores the mode.
While storing as B l= 1 or 2 (68)
, is sent to the mode determination section 24. The mode determination unit 24
Please judge whether mode A = mode B 169)
, when they are the same, that is, when mode B 1 = 2, the process returns to determining whether it is the beginning of a sentence (65). Then, as the cursor data is decremented, mode A and mode B are sequentially changed.
2 # mode B3 e- will be compared. The character at the position indicated by the cursor data is Hiragana and mode
When A'xi, mode B 1 is reached, a selection signal is output from the mode determination section 24 to the cursor position storage section 18.

When the selection signal is input, the cursor position storage unit 18 increments the cursor data sent from the cursor movement unit 20 by 1 and stores it as second cursor data representing the first character position of the Katakana character string desired to be converted. Do (70).

The first . Once the second cursor data is stored, this data is sent to the hiragana/katakana converter 26. The hiragana/katakana converter 26 to which the shift signal is input converts the kana character string data of the section indicated by the first and second cursor data in the input line storage area of the memory 20 into the corresponding hiragana character string data. Do (71).

Next, the operator judges whether all the mode conversions of the hard character strings in the input sentence in the part that has already been input have been completed (72). Convert other kana strings in the input sentence. The input sentence, all corrected to hiragana character strings, is displayed on the screen. Therefore, if the remaining uninput characters are input in hiragana, the Japanese processing unit 16 converts the input sentence into kana-kanji. If there is only one kana character in the input sentence, the first cursor data becomes the second cursor data and the mode is converted in the same way.

In the above embodiment, the case where a Japanese sentence inputted using the Kana key is converted to kana-kanji was explained as an example, but the present invention is not limited to this in any way, and the case where a Japanese sentence inputted using the Romaji key is converted to Kana-Kanji is explained as an example. This method can also be directly applied when converting Roman characters to Kanji.

According to the present invention, when inputting Japanese using kana characters, even if there are kana characters entered in the wrong mode, the mode can be corrected for multiple characters at once with a simple operation. This eliminates the need for re-input, allowing for faster input work. In addition, when editing on the screen after Kana-Kanji conversion, you can change the mode of the Hiragana character string or Katakana character string consisting of multiple consecutive characters that have already been input at once for the desired range, so the editing work can be done. This makes it possible to obtain a Japanese language processing device with extremely good operability as a whole.
