Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character processing device that performs kana-kanji conversion processing on an input kana character string, and in particular, to a character processing device that can repeatedly perform various types of signal processing on the same input kana character string. This is what I did.

In a conventional character processing device of this type, an input kana character string is temporarily stored in a storage means and then subjected to a kana-kanji conversion process, but when the kana-kanji conversion process is completed, the input kana character string is deleted from the storage means.
I couldn't make it stay. Therefore, after first performing kana-kanji conversion processing on the input kana character string, it is possible to use a character processing mode other than kana-kanji conversion, for example, to output the input kana character string in the form of voice output, or to use it in various fields. Equipped with a separate dictionary,
If you specify a desired field and search a dictionary for that field, and then change the field specification and repeatedly search the dictionary, you will need to re-enter the same kana character string each time. There was a drawback.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks, to enable the same input character string to be repeatedly subjected to various types of signal processing, and to provide highly efficient character processing that eliminates the need to input the same character string again. The purpose of this invention is to provide a processing device.

In other words, even after performing kana-kanji conversion processing on an input kana character string, the character processing device of the present invention allows the input kana character string to remain in a storage means such as an IC memory, and transmits the input kana character string to other types of signals. When processing, for example, signal processing such as conversion to audio output or kana-kanji conversion with different field specifications, the same input remains in the storage means without inputting the same kana character string again. This is a kana character string that can be used repeatedly.

The present invention will be described in detail below with reference to the drawings.

First, an example of the overall configuration of the character processing device of the present invention is shown in FIG. In the illustrated configuration, 1 is a microprocessor that processes data for the entire device;
Reference numeral 2 denotes an address bus that transmits address signals specifying storage addresses of each input/output memory. 3 is a bidirectional data bus used to transfer various data between each component, and 4 is a control bus that controls writing, reading, interrupt reception, and data set timing for each memory device, etc. Used to transmit control signals such as

Further, 5 is a keyboard, which includes a group of character keys such as an alphanumeric key, a hiragana key, and a katakana key, a cursor key group for operating a cursor on a text display surface, and a monitor having a function of shifting the homophone display on the monitor line. It is equipped with a group of line shift keys and a selection key for selecting and extracting desired characters.

Next, a keyboard controller 6 encodes data input from the keyboard 5 and sends an interrupt signal to the control bus 4. A CRT controller 7 controls a CRT display device 8, a character generator 9, a refresh memory 10, a refresh memory controller 11, and the like. Thus, the CRT display device 8 can perform a display similar to that of a normal television receiver, and the character generator 9 can display those characters by inputting codes such as character codes and character pattern line addresses. The patterns in the corresponding rows of the pattern are sequentially output, and in the refresh memory 10,
The character code of the character to be displayed on the CRT display device 8 is stored, and the character code read out repeatedly according to the display instruction from the CRT controller 7 is output.
It controls the refresh cycle for CRT display and the writing and reading of data to and from the microprocessor 1 in response to instructions from the controller 7.

Next, 12 is a read-only memory, that is,
This is a so-called ROM that stores control procedures for the entire device as well as various processing means, and 13 is a controller for the ROM 12. Further, 14 is a random access memory, that is, a so-called RAM, which is used for temporary storage of various data.As shown in the figure, in addition to having a data register IDST and a work register WORK, it also stores, for example, input text. A sentence buffer memory SB for storing, a homophone table memory ST for storing multiple homophones generated during kana-kanji conversion, an input data register INDR for storing key signals input from the keyboard 5, and a cursor position. Cursor register CR, CRT that stores
It includes a display register DR that stores the beginning position of a sentence to be displayed on a display device, and a monitor register MR that stores the beginning position of a homophone string to be displayed on the display surface of the monitor line. Furthermore, 15 is RAM1
4, a floppy disk 16 stores a dictionary for character conversion; 17 a floppy disk drive device for driving the floppy disk 16; 18 a floppy disk drive controller; 19 a printer; 20 controls the printer 19. It is a printer controller that

The character processing device of the present invention, which is composed of the above-mentioned components, is operated by input data from the keyboard 5, and when data is input from the keyboard 5, an interrupt signal is sent to the microprocessor 1.
various character processing operations are performed according to control means stored in the ROM 12. The operation of the apparatus of the present invention will now be described with reference to the flowchart shown in FIG.

First, in step S-1, the keyboard 5
input data string from random access memory 1
4, and then in step S-2,
The microprocessor 1 determines whether the input data is an instruction to start kana-kanji conversion, and if the input data is not an instruction to start conversion, the process moves to step S-10 and performs various input processing, such as normal English characters, kana characters, etc. etc. and character codes. Note that this input processing is performed in the same manner as well-known input processing using a normal word processor or the like, so a detailed explanation thereof will be omitted.

On the other hand, if the input data is an instruction to start kana-kanji conversion, the process moves to step S-3, where the input data string is written to the data register IDST in the RAM 14, and similarly, the input data string is written into the data register IDST in step S-4. Work register WORK in RAM14
write to.

Next, in step S-5, kana-kanji conversion processing is performed using the input data string written in the work register WORK, and further, in step S-5,
-6, other data processing is performed, such as weighting the appearance rate of each homophone and displaying it on the display. Next, in step S-7, data instructing other data processing modes using the above-mentioned input data string, such as voice output conversion and field switching search in field-specific dictionaries, is input from the keyboard 5. If such an instruction is received, proceed to step S-9.
Write the input data string in data register IDST to work register WORK, then step S
-8, the input data string written to the work register WORK is used to perform other data processing according to the data processing mode specified above. Then, the process returns to step S-6, and the series of data processing described above is repeated until there are no instructions for data processing in other modes in step S-7. Therefore, when there is no longer any instruction for data processing in other modes in step S-7, the series of required data processing for the input data is completed.

It is assumed that the data register IDST and the work register WORK are configured with a plurality of words corresponding to the input data string.

However, in the above explanation, the input data string written to the data register IDST is rewritten to the new input data string when a new input data string is input next time. Separately, a register is provided to store and hold the input data string for a long period of time, and the input data string written in the long-term register can be read out by key input or other means as needed, for example, for kana-kanji conversion processing. It is also possible to perform desired data processing again.

As is clear from the above description, according to the present invention, by inputting an input character string only once, various functions such as kana-kanji conversion, voice output, and re-kana-kanji conversion by changing the dictionary to be searched can be performed. Since character processing can be performed repeatedly, it is possible to realize a character processing device that is more efficient than conventional ones.
