Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus that performs document processing such as creation and editing of a document.

[Conventional technology]

In a conventional document processing apparatus, since a Japanese document is mainly created, a word is generally input in a hiragana mode. Therefore, in order to input katakana in the hiragana mode, a method of switching from the hiragana mode to the katakana mode and inputting a desired katakana word,
Alternatively, when Katakana is registered in a word storage device (dictionary), a method of inputting in Hiragana mode and then converting it to the corresponding Katakana has been used.

[Problems to be solved by the invention]

By the way, in the above-mentioned conventional document processing apparatus, when the Katakana language is input, the mode must be switched every time the Katakana mode is input. A lot of time had to be spent on document processing such as.

On the other hand, in the method of converting from hiragana to katakana, if a katakana word that is not registered in the word storage device is input, it is necessary to switch to the katakana mode every time the input is performed and to input a desired katakana word. Alternatively, a desired katakana word is registered in a storage device different from the word storage device in advance, and the word is input in the Hiragana mode in a hiragana mode, and the input word is input using a conversion unit that converts hiragana to katakana. Must be converted to Katakana. For this reason, every time a Katakana word is input, a mode switching operation or an operation of registering the Katakana language in advance has to be performed, and much time has to be spent for document processing. In particular, unregistered katakana is often used as a keyword of a document, and frequently appears in the same document.

The present invention has been made in view of the above circumstances, and has as its object to provide a document processing apparatus that can improve the processing efficiency of document processing.

[Means for solving the problem]

According to the present invention, there is provided a storage means for storing a character string input and confirmed in a second input mode different from a preset first input mode, and a character string stored in the storage means in the first input mode. When a character string corresponding to the input character string is input, a conversion unit for converting the input character string into a character string in the second input mode format is provided.

[Action]

In the present invention, the unregistered katakana words that have been entered and confirmed in the katakana mode as the second input mode are stored in the storage means. When inputting the katakana words stored in the storage means, the input character string is not changed to the katakana mode, but is input in the hiragana mode as the first input mode. Is converted to a katakana character string.

〔Example〕

Hereinafter, embodiments of the document processing apparatus according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram showing one embodiment of a document processing apparatus according to the present invention. In the figure, an input device 1 is provided with various character key groups such as a hiragana character, a katakana character, and an alphanumeric character, a function designation key for designating other functions, a hiragana mode, a katakana mode, an alphanumeric mode, and the like. Operation keys such as an input mode designating key for designating the corresponding input mode, and a kana-kanji conversion key for converting "Hiragana" to "Kanji" and "Hiragana" to "Katakana" are provided. It has a keyboard and is used to input a character string of a reading kana.

The mode control device 2 recognizes an input mode such as a hiragana mode, a katakana mode, or an alphanumeric mode, and sends an input character or command to a predetermined device according to the input mode.

The character conversion device 3 has a character string buffer, temporarily stores the hiragana characters from the mode control device 2 in the buffer, and sends a character string buffer to the dictionary search device 5 that searches the storage contents of the storage device 4. Is searched in the storage device 4 to determine whether the character string is stored in the storage device 4. According to the search result from the dictionary search device 5, conversion from "Hiragana" to "Kanji" or conversion from "Hiragana" to "Katakana" is performed. I do.

The storage device 4 includes a word dictionary 4A as a system dictionary having pre-registered word information for conversion from “Hiragana to Kanji” and word information for conversion from “Hiragana to Katakana”; A katakana registration storage device (a katakana registration dictionary) 4B for registering katakana words not registered in 4A.

The katakana registration device 6 has a character string buffer, and temporarily stores the katakana characters from the mode control device 2 in the buffer, and stores the character strings in the character string buffer in the dictionary search device 5. If the search result from the dictionary search device 5 is information indicating that the Katakana language is not registered, the search result corresponds to the katakana registration storage device (Katakana registration dictionary) 4B. Register the katakana character string.

The display device 7 includes a display, and displays an edited document, a character string of an input kana, and a character string read from the storage device 5.

Next, the document processing operation of the document processing apparatus will be described with reference to the flowcharts of FIGS.

As shown in FIG. 2, when a user presses an input mode designation key or a specific key of a keyboard provided on the input device 1 (step 100), the mode control device 2
Based on the signal corresponding to the pressed input mode designating key, it is determined which of the input modes of Kanata, Hiragana, and alphanumeric is the input mode (step
101).

Here, in the case of the alphanumeric mode, the mode control device 2 determines whether or not the signal corresponding to the pressed key is a character code (step 102). 7 (step 103), and waits for the next key input (step 104). If it is not a character code in step 102, the mode control device 2 determines whether another input mode designating key has been pressed (step 105). Then, the mode is switched to the corresponding input mode (step 106). Then, when the mode controller 2 terminates Step 106 or does not press any other input mode designation key in Step 105, it waits for the next key input.

In step 101, if the mode is the katakana mode, katakana mode processing is performed (step 200).
If the mode is the hiragana mode, hiragana mode processing is performed (step 300).

Next, the operation of the katakana mode processing will be described with reference to the flowchart of FIG.

Now, consider a case where a character string “word processor” is input in the katakana mode.

First, it is assumed that the input mode designation key indicating the katakana mode is depressed by the user, and "wa", "-", "pu", and "b" are sequentially input one by one in the katakana mode.

Thus, the mode control device 2 determines that the mode is the katakana mode based on the signal corresponding to the input mode designation key indicating the katakana mode, and determines whether or not the mode change key is pressed next, that is, the input other than the katakana mode. It is determined whether or not an input mode designating key indicating a mode (a hiragana mode or an alphanumeric mode) has been pressed (step 201), and the result of the determination and the input characters are sent to the katakana registration device 6.

The Katakana language registration device 6 stores the input mode control device 2
If the result from the step (a) indicates that the input mode designation key has not been pressed, the input character is stored in the character string buffer (step 202), and at the same time, the input character is transmitted to the display device 7 (step 203). ). The display device 7 sequentially displays “W”, “−”, “P”, and “B” in katakana.

Next, the katakana language registration device 6 determines whether the input result from the mode control device 2 is that the input mode designation key has been pressed, that is, the character string determination information indicating the determination of the character string. It recognizes that the character string in the column buffer has been determined, and sends the character string in the character string buffer to the dictionary search device 5 to determine whether or not the character string is registered in the storage device 4. Is checked (step 204).

If the notification result from the dictionary search device 5 that has searched the word dictionary 4A and the katakana registration storage device 4B is not registered, the katakana registration device 6 sets the character string (character string " Word processor) is registered in the katakana registration storage device 4B (step 205), the contents of the word character string buffer are cleared (step 206), and if the word string is registered, the processing in step 206 is performed. Will run.

Then, the katakana registration device 6 executes the above-described step 20.
When 3 has been completed, or when step 206 has been completed, the control is transferred to the mode control device 2. As a result, the mode control device 2 executes step 104 shown in FIG.

Next, the operation of the hiragana mode processing will be described with reference to the flowchart of FIG.

First, it is assumed that the user presses the input mode designation key indicating the hiragana mode, and the characters are sequentially input in hiragana mode in order of "wa", "-", "@", and "ro".

Accordingly, mode control device 2 determines that the mode is the hiragana mode based on the signal corresponding to the input mode designation key indicating the hiragana mode, and then determines whether the kanji conversion key is pressed (step 301). ), And sends the result of the determination and the input character to the character conversion device 3.

The character conversion device 3 stores the input character in the character string buffer when the input determination result from the mode control device 2 indicates that the kanji conversion key has not been pressed (step S1).
302) Then, it is checked whether or not the input character is determined as "Hiragana" (step 303). If the result of the check is not determined, the character in the character string buffer is displayed on the display device 7. It is sent (step 304). As a result, the display device 7 sequentially displays “Wa”, “−”, “ぷ”, and “R” in hiragana.

On the other hand, in step 303, when the input character string is determined to be "Hiragana" by pressing another input mode designation key or the like, the character conversion device 3 clears the contents of the character string buffer (step 303). 305).

Further, the character conversion device 3 determines that the kanji conversion key has been pressed when the input determination result from the mode control device 2 indicates that the kanji conversion key has been pressed.
The character string in the character string buffer is sent to the dictionary search device 5 to check whether or not the character string is registered in the storage device 4 (step 306).

If the notification result from the dictionary search device 5 that has searched the word dictionary 4A and the katakana registration storage device 4B is registered, the character conversion device 3 stores the character string in the character string buffer in the storage device. 4 is converted to a corresponding character string, that is, "Wapro" is converted to "word processor" (step 307). Thereafter, the contents of the character string buffer are cleared, and Then, the character string of Hiragana is erased and the character string after conversion is displayed (Step 308). As a result, the display device 9 displays the character string converted from “Wapro” to “Word processor”.

In step 306, if the notification result from the dictionary search device 5 is not registered in step 306, the kanji conversion key is pressed in step 301. It recognizes that it has been determined to be "Hiragana", and clears the contents of the character string buffer as described in step 305 above.

Then, the character conversion device 3 transfers the control to the mode control device 2 when the above-described step 304 is completed or when the above-described step 308 is completed. As a result, the mode control device 2 executes step 104 shown in FIG.

According to the above embodiment, after the katakana that has not been registered in the storage device, the character string is registered in the katakana registration storage device once by being entered and confirmed in the katakana mode, so that the registered character string is input from the next time. Can be converted to katakana by inputting in Hiragana mode in the same manner as a word registered in the dictionary in advance, and pressing a kanji conversion key.

Also, it is not necessary to register Katakana, which is a keyword that frequently appears in the same document, in the user dictionary, and it is possible to reduce the mode switching operation from Hiragana mode to Katakana mode and vice versa.
The load on the user can be reduced.

〔The invention's effect〕

As described above, according to the present invention, when an unregistered character string in the second input mode other than the preset first input mode is input and confirmed, the character string is stored in the storage means. With respect to the character string registered in the storage means, when a character string is input in the first input mode from the next time, a character in the second input mode corresponding to the input character string is stored. Since the conversion into columns is performed, the mode switching operation can be reduced, and there is an advantage that document processing such as creation and editing of a document can be performed quickly.
