Description

Description: TECHNICAL FIELD The present invention relates to a Japanese language processing device, and more specifically, to kana characters in an input Japanese sentence from hiragana characters to katakana characters, or katakana characters. The present invention relates to a Japanese language processor having a Hiragana-Katakana conversion function for converting characters into Hiragana characters.

2. Description of the Related Art Japanese language processing devices have rapidly spread 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, in a kana-kanji conversion type, a Japanese sentence input with kana characters by a keyboard is converted into kana-kanji characters and displayed on the screen. Then, the operator can perform desired editing work such as insertion, deletion and correction while looking at the screen. The keyboard has a kana key and a kana mode designation key for performing mode switching between hiragana and katakana (where mode refers to a type such as hiragana, katakana, kanji, and English characters). The operator can switch the kana mode designating key to select the hiragana input or the katakana input.

By the way, in the conventional Japanese language processing device, when inputting Japanese, the mode of Hiragana and Katakana is wrong,
When an input is made in a mode different from the mode in which the input was attempted, even if the mode is switched from then on, it is effective only for the subsequent key input, and the mode changing process is not performed for the characters already input. Therefore.
I had to redo the Japanese input or correct it in the editing work to be performed later. On the other hand, since the correction in the editing work can be processed only on a character-by-character basis, if there are multiple erroneously input characters in a line, the cursor movement, the correction key operation, and the correction key input operation are repeated individually. It has to be performed, which is very inconvenient in operation and causes a reduction in work efficiency.

The object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to view a Japanese sentence displayed on the screen by a simple key operation, and at the same time, enter a Hiragana or Katakana character string that has already been input in a certain mode. It is an object of the present invention to provide a Japanese language processing device having good operability, which can be converted into a Katakana or Hiragana character string of the mode.

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

FIG. 1 is a block diagram showing a configuration example of a kana-kanji conversion type Japanese processing device according to the present invention. In the figure, a Japanese processing unit 14 is provided on the keyboard 10 via the key determination unit 12.
Are connected. The keyboard 10 has various keys necessary for performing Japanese input operations, kana-kanji conversion, editing operations, etc., such as character keys such as kana key and alphabetic key, function keys such as insert key, delete key, and correction key. When the key is pressed, the code data corresponding to each key is output. The keyboard 10 is also provided with katakana keys, shift keys, hiragana / katakana conversion keys, and cursor keys. If you press the Kana key with the Katakana key released, you can enter Hiragana characters, and if you press the Kana key with the Katakana key pressed, you can enter Katakana characters. Japanese input is done in plain text using kana characters. The Hiragana / Katakana conversion key is for instructing the mode conversion of the Kana characters that have already been entered.When the shift key is pressed down, it is converted from Hiragana to Katakana, and when the shift key is pressed, it is Katakana. Represents the conversion from Japanese to Hiragana. When you operate the cursor keys,
The moving amount data is output to the cursor moving unit 16 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 or not the input data from the keyboard 10 is a command related to the Hiragana / Katakana conversion key. When the character data or the command other than the command related to the Hiragana / Katakana conversion key is input, It is directly output to the word processing unit 14. When a command related to the Hiragana / Katakana conversion key is input, a read signal is output to the cursor position storage unit 18 connected to the output side.

The Japanese processing unit 14 first writes a solid Japanese sentence sent from the keyboard 10 by an operator's input operation to the memory 2
0 is stored in the input row storage area. Then, when a punctuation mark or a space is input, the Japanese processing unit 14 performs kana-to-kanji conversion on the Japanese sentence of the full text stored in the input line storage area using the word dictionary and grammatical rules and stores it in the converted line storage area of the memory 20. The CRT control unit 2 is provided on the output side of the memory 20.
2, CRT display 24 is connected, memory 2
The input sentence and converted sentence data accumulated in 0 are converted into character patterns and displayed at predetermined input line display positions and converted line display positions on the screen, respectively. The CRT control unit 22 also displays a cursor on the screen based on the cursor data sent from the cursor moving unit 16.

The Japanese processing unit 14 also has an editing function of deleting / inserting / correcting a converted sentence. When the operator operates the cursor keys of the keyboard 10 to specify the position in order to change the conversion sentence displayed on the screen, the cursor moving unit 16
From the cursor data is input to the Japanese language processing unit 14.
When an edit key such as a delete / insert / correct key (except for the hiragana / katakana conversion key) and a character key required for change are operated, the corresponding command and character data are sent to the Japanese language processing unit 14.

The Japanese processing unit 14 reads out the converted sentence stored in the memory 20 based on the input editing command, and deletes / inserts / corrects the converted sentence to correct / change the sentence. The edited converted sentence is stored again in the converted line storage area of the memory 20 and displayed on the screen.

Also, when the Japanese processing device according to this configuration example is performing Japanese input with Kana characters, and wants to correct the wrong Hiragana character string or Katakana character string mode that has already been input, If you move the cursor to the last character of the desired kana character string displayed on the input line of the screen and then press the Hiragana / Katakana conversion key, you can go back and perform mode conversion for multiple characters at once.
When you want to change the mode of the Hiragana character string or Katakana character string displayed on the conversion line of the screen during editing, if you want to convert the first and last characters of the desired Kana character string displayed on the conversion line of the screen. After you put the cursor on and press the Hiragana / Katakana conversion key respectively, you can convert the kana character string in the section specified by the cursor to the mode at once.

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. Further, at this time, if the shift key is pressed, the key determination unit 12 causes the hiragana / katakana conversion unit 26 connected to the output side of the cursor position storage unit 18 to indicate that the shift key is pressed. Is sent. The cursor position storage unit 18 has a function of storing a section of a kana character string whose mode is to be converted. When the first read signal is input, the cursor position storage unit 18 firstly moves the cursor moving unit 1 at that time.
The cursor data output by 6 is read and stored as the first data. Subsequently, it is determined whether the cursor data is data on the converted line display area of the screen or data on the input line display area. In the former case, the key determination unit 12 waits until the next read signal is input. After moving the cursor by operating the cursor keys, press the Hiragana / Katakana conversion key to 2
When the second read signal is input, the cursor position storage unit 18
Is again the second output by the cursor moving unit 16 at that time.
Read and store the cursor data of. The first and second cursor data stored in the cursor position storage unit 18 represents a section of a kana character string in the conversion sentence for which mode conversion is desired.

Separately, when the cursor data input from the cursor moving unit 16 in response to the first read signal is data that covers the input line display area of the screen, the cursor position storage unit 18 uses this data as the first cursor data. The memory is stored and a cursor retreat signal is output to the cursor moving unit 16.

The cursor moving unit 16 has a cursor data register, and when moving amount data in the x direction or the y direction is input from the keyboard 10 by operating the cursor keys, the cursor data is added to or subtracted from the cursor data stored in the register to update the cursor data. When a cursor backward signal is input from the cursor position storage unit 18, the cursor data stored in the register is sequentially decremented and the cursor is moved backward character by character. This backward movement of the cursor data is performed until a stop signal is input from the cursor position storage unit 18. The cursor data stored in the cursor moving unit 16 is sent to the CRT control unit 22 so that the cursor is displayed on the screen and is also sent to the cursor position storage unit 18 during the mode conversion process of kana characters. Further, when the cursor backward signal is input to perform decrement, the cursor data is sent to the mode storage unit 28 connected to the output side of the cursor moving unit 16.

When the cursor data is input from the cursor moving unit 16, the mode storage unit 28 reads the character data at the address indicated by the cursor data from the input line storage area of the memory 20, and whether the character mode is Hiragana (mode = 1) or not (mode = 2)
Identify. The mode of the character (the last character of the kana character string to be converted) A related to the first cursor data specified by the operator before decrementing
The mode A (= 1 or 2) is set, and the character mode related to each cursor data during decrement is modeB ₁ , modeB ₂ ,
It is stored as modeB ₃ , ... (= 1 or 2) and is output to the mode determination unit 30 connected to the output side.

The mode determination unit 30 sequentially compares modeB ₁ , modeB ₂ , ... That are transmitted from the mode storage unit 28 according to the decrement operation of the cursor data with reference to modeA. When a character of a mode different from the last character of the kana character string desired to be converted becomes modeA ≠ modeB _i , a selection signal is output to the cursor position storage unit 18. The cursor position storage unit 18, which has received this selection signal, inputs the cursor data output by the cursor moving unit 16 at that time, increments it by 1 and stores it as second cursor data. However, even if the cursor moves backward to the beginning of the input line, mode
When A ≠ modeB _i is not satisfied, the beginning address is used as the second cursor data. Thus, if the last character position of the kana character string for which mode conversion of the input line is desired is designated, the first character position is automatically selected.

A hiragana / katakana conversion unit 26 is connected to the output side of the cursor position storage unit 18. Cursor position storage unit 1
After finishing the operation of selecting the section of the kana character string to be converted, 8 outputs the first and second cursor data representing the range to the hiragana / katakana conversion unit 26. The hiragana / katakana conversion unit 26 is connected to the memory 20. The kana character string data in the section represented by the first and second cursor data is read from the memory 20, the mode is converted, and the mode is converted again. It is adapted to be stored in the memory 20.
However, the hiragana / katakana conversion unit 26 is the key determination unit 12
When a shift signal is being input from, the mode conversion is performed from katakana to hiragana, and when there is no shift signal input, the mode is converted from hiragana to katakana. The mode conversion process can be performed by a certain number of additions and subtractions by utilizing the fact that the hiragana code and the katakana code have a certain correspondence relationship.

The stored contents of the memory 20 in which the kana character string mode is 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 14 is executed as described above after the completion of inputting one sentence.
Big Kanji conversion is done. Further, when the mode of the kana character string in the conversion line is corrected, other editing work such as insertion / deletion can be performed subsequently.

Next, the overall operation of the above embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a flow chart showing the operation in the case of performing mode conversion of the kana character string in the conversion sentence at the time of editing, and FIG. 3 is a flow chart in the case of performing mode conversion of the kana character string in the input sentence at the time of input.

First, referring to FIG. 2, a case of converting a hiragana character string in a conversion sentence into a katakana character string will be described. First, the operator operates the cursor keys while looking at the screen to position the cursor on the first character position of the hiragana character string for which the mode conversion is desired, in the conversion line. At this time, the cursor moving unit 16 outputs the cursor data at the first character position to the cursor position storage unit 18. Then, the hiragana / katakana conversion key is pressed with the shift key released, and a command is sent to the key determination unit 12.

The key determination unit 12 determines in advance whether or not there is a key input from the keyboard 10 (50), and when there is a key input, determines whether or not the input is from a hiragana / katakana conversion key (51) and other keys. When inputting, Japanese processing unit 14
Then, the corresponding processing is performed (52). When the key is the Hiragana / Katakana conversion key, 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 the data related to the conversion line, the cursor position storage unit 18 next reads the hiragana /
It is determined whether the katakana conversion key has been pressed twice (54). If not, the flow returns to the flow of key input (50). Here, when the operator positions the cursor on the last character position of the hiragana character string desired to be converted and presses the hiragana / katakana conversion key, the cursor position storage unit 1 is operated in the same manner as described above.
The second cursor data output by the cursor moving unit 16 at that time is stored in the memory 8 (53).

When the hiragana / katakana conversion key is pressed twice to store the first and second cursor data in the cursor position storage section 18, this data is sent to the hiragana / katakana conversion section 26. The hiragana / katakana conversion unit 26 to which the shift signal is not input is the first in the conversion row storage area of the memory 20.
The hiragana character string data in the section indicated by the second cursor data is converted into the corresponding katakana character string data (5
5). On the screen, katakana character strings are displayed with the converted sentences corrected at once. Next, the operator judges whether or not the mode conversion of the kana character string in the conversion sentence has been completed (56). When the operation is completed, the flow is ended. Convert mode.
At this time, if it is desired to convert a katakana character string into a hiragana character string, the shift key may be pressed in advance.

If the cursor is moved to a certain kana character in the conversion sentence and the hiragana / katakana conversion key is pressed twice in succession, the first cursor data = the second cursor data, and the mode can be converted only for one character.

Next, referring to FIG. 3, a description will be given of a case where a Japanese character input in Hiragana mode is corrected to a Hiragana character string by mistake. First,
While looking at the screen, the operator operates the cursor keys to move the cursor to the last character position of the katakana character string for which mode conversion is desired among the input sentences displayed in the input line display area. Then press the shift key and press hiragana.
Press the Katakana conversion key and send a predetermined command to the key determination unit 1
Send to 2.

The key determination unit 12 determines in advance whether or not there is a key input from the keyboard 10 (60), and if there is a key input, further determines whether or not the input is from a hiragana / katakana conversion key (61), etc. When the key is pressed, the Japanese processing section performs the corresponding processing (62). When using the Hiragana / Katakana conversion key, the key determination unit 12 outputs a shift signal to the Hiragana / Katakana conversion unit 26, a read signal to the cursor position storage unit 18, and a cursor moving unit 16. The cursor data of 1 is stored (63). Since this cursor data is data relating to the input line, the cursor position storage section 18 sends a backward signal to the cursor moving section 20.

The cursor moving unit 20 that has input the backward signal sends the cursor data to the mode storage unit 22 before decrementing the cursor data. The mode storage unit 22 identifies the mode of the kana character (here, katakana character) at the position indicated by the cursor data in the character data stored in the input line storage area of the memory 20, and stores it as modeA = 2 (64 ) Send to the mode determination unit 24.

On the other hand, the cursor position storage unit 18 determines whether the cursor data input from the cursor moving unit 20 is the beginning of a sentence on the input line (65). If the cursor data is the beginning of the sentence, the first cursor data = the second cursor data and the Hiragana / Katakana conversion unit The data is sent to 26. The Hiragana / Katakana conversion unit 26 receiving the shift signal converts the Katakana character in the memory 20 corresponding to the cursor data into the Hiragana character (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 returns the cursor by one character (67) and sends the decremented cursor data to the mode storage unit 22. To 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 modeB ₁ =
It is stored as 1 or 2 (68) and is sent to the mode determination unit 24. The mode determination unit 24 uses modeA = mode
It is judged whether it is B ₁ (69), and when it is the same, that is, when mode B ₁ = 2, the process returns to the judgment of whether it is the beginning of a sentence (65). Then, with the decrement of the cursor data, modeA and modeB ₂ ,
The mode B ₃ , ... Are compared. When the character at the position indicated by the cursor data is in hiragana and modeA ≠ modeB _i , the mode determination unit 24 outputs a selection signal to the cursor position storage unit 18.

The cursor position storage unit 18 increments the cursor data sent from the cursor moving unit 20 by 1 when a selection signal is input, and stores it as second cursor data representing the first character position of the katakana character string desired to be converted. Yes (70).

When the first and second cursor data are stored in the cursor position storage unit 20, this data is sent to the Hiragana / Katakana conversion unit 26. The Hiragana / Katakana conversion unit 26 that inputs the shift signal converts the katakana character string data in the section indicated by the first and second cursor data in the input row storage area of the memory 20 into the corresponding Hiragana character string data. Yes (71).

Next, the operator judges whether or not all the mode conversions of the katakana character string in the input sentence in the already input portion have been completed (72). When the operation is completed, the flow is ended. Convert other katakana character strings. On the screen, the input sentence corrected to all Hiragana character strings is displayed. Therefore, if the remaining unentered characters are entered in Hiragana, the Japanese processing unit 16 functions to convert the input into Kana-Kanji. When only one character is included in the input sentence, the first cursor data = the second cursor data and the mode is similarly converted.

In the above embodiment, the case where the Japanese sentence input using the Kana key is converted into Kana-Kanji has been described as an example, but the present invention is not limited to this. It can be applied as it is when converting Roman characters to Kanji.

Effect According to the present invention, as described above, when performing Japanese input using kana characters, even if there is a kana character entered in the wrong mode, it is possible to correct the mode for a plurality of characters at once with a simple operation. Since it can be performed, it is possible to save time and labor for re-inputting and perform quick inputting work. Also, when performing editing work on the screen after Kana-Kanji conversion, the mode of the Hiragana character string or Katakana character string consisting of multiple consecutive characters that has already been input can be converted at once for the desired range. This makes it easy to obtain a Japanese language processing device with extremely good operability as a whole.
