Abstract

PURPOSE:To input a character data string rapidly and to improve the efficiency of conversion processing by changing KANA (Japanese syllabary)/KANJI (Chinese character) conversion algorithm by inputting a prescribed command. CONSTITUTION:An ROM stores processing programs PG1-PG12 corresponding to the conversion commands of KANA/KANJI conversion algorithm. A KPARAM built in an RAM is a KANA/KANJI conversion algorithm specifying register indicating the kinds of the KANA/KANJI conversion algorithm and stores the parameters of the KANA/KANJI conversion algorithm converting commands. When a command is inputted from a keyboard KB, the processing program in the ROM is read out by the specification of the KPARAM. Since the KANA/KANJI algorithm can be optionally selected, the character data string can be inputted rapidly and the efficiency of the conversion processing can be improved.

Description

TECHNICAL FIELD The present invention relates to a character processing device, and more particularly to a character processing device suitable for processing Japanese sentences using a kana-kanji conversion method.

Prior Art Conventional character processing devices using the kana-kanji conversion method generally have only a single character processing algorithm, and the processing algorithm cannot be changed according to the operator's wishes.

In this type of character processing device, when performing the process of converting kana to kanji, a notation (Q
This process is performed by searching a dictionary developed within the department. Some of these dictionaries include fields such as general fields, engineering fields, and administrative fields. For example, if an operator wants to output the honorific word "machine" that belongs to the engineering field, When you input the kana character °°Kikaipa, the character processing device inputs all the r characters in the dictionary.
P, search for the word, and in addition to the desired "machine", "your association",
Homonyms such as "opportunity", "monster", and "instrument" may be output. Therefore, in a character processing device that performs kana-kanji conversion using such a character processing algorithm, there are problems in that the search takes time and the conversion efficiency is not improved.

In addition, by using the kanji part designation method, segmented division method, etc.
There are character processing devices that have multiple kana-kanji conversion processing algorithms, but in such character processing devices, the operator selects a desired algorithm from the multiple character processing algorithms displayed on the display screen when starting work. Since the method is adopted, once such selection is made,
Only selected processing algorithms could be used. Therefore, if you want to use multiple processing algorithms at the same time, you must return to the display screen at the start of work and reselect the desired algorithm. There was a problem that the speed of inputting columns was slow.

On the other hand, there are character processing devices that are equipped with a dedicated key to change the processing algorithm, but the provision of such a key makes the device itself expensive.
Furthermore, when a large number of processing algorithms are provided, the number of keys increases accordingly, which inevitably makes blind touching impossible, resulting in a problem that the operator's input speed decreases.

Purpose The purpose of the present invention is to eliminate the problems mentioned in -1-
By manually inputting commands on the W"J screen to change the character conversion processing algorithm without using specific keys, IN1 Sakunagi can input character data at high speed, and An object of the present invention is to provide a character processing device that has high conversion efficiency and is inexpensive.

Example Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of the character processing device of the present invention, in which the CPU is a microprocessor that performs calculations, logical judgments, etc. for character processing, and connects an address bus AB, a control bus CB, and a data bus DB. control each component connected to those buses.

Address bus AB transfers address signals indicating the components to be controlled by the microprocessor CPU. The control bus CB transfers control signals for each component controlled by the microprocessor CPU and supplies them to each component.

The data bus DB transfers data between each component device.

The ROM is a read-only fixed memory (read-only memory), and the processing program PCI according to the control procedure by the microprocessor CPU described in FIGS. 3 and 4 and the conversion commands of the kana-kanji conversion algorithm (see FIG. 2). , PG2゜PO2,..., PCl
Remember the 3rd place.

Further, the RAM is a writable random access memory in which, for example, one word is 16 bits, and is used for temporary storage of various data from each component.

KPARAM is a kana-kanji conversion algorithm designation register that indicates the type of kana-kanji conversion algorithm, is provided in the random access memory RAM, and stores parameters of a change command for the kana-kanji conversion algorithm.

KB is a keyboard, which includes various functions for instructing various functions to the character processing device of the present invention, such as alphabet keys, flat keys, katakana keys, etc., which contain character symbols, and kanji part start/end designation keys. Comes with a key.

The DISK is a disk memory that not only stores standard documents but also stores created documents, and the stored documents can be called up when necessary by an operator pointing the keyboard KB.

CR is a cursor register, and the content of the cursor register CR is read/written by the CPU. C
The RTC is a CRT controller, and in addition to displaying a cursor at the position on the display CRT corresponding to the address stored therein, it also controls the display pattern of the dot configuration on the display CRT, and also controls the cursor register CR and buffer memory. The contents stored in DBUF are displayed on the display.

The buffer memory DBtIF temporarily stores document information and the like input from the keyboard KB.

CG is a character generator, which generates character signals such as characters, symbols, and cursors to be displayed on the display CRT.

The character processing device of the present invention, which is composed of each of these components, operates in response to various input signals from the keyboard KB, and when a signal from the keyboard KB is supplied, an included signal is first sent to the microprocessor CPU, The microprocessor CPU reads out various control signals stored in the ROM, thereby performing control according to these control signals.

Next, we will show two examples of input using a command to change the kana-kanji conversion algorithm and output for that input.

(First example) Irikani (Kanjishidei) (Quickly Haya)

The crabs appear very quickly.

(2nd example) Human crab (bunsetsu city) (quickly) (quickly)
(Hail.) The crabs appear very quickly.

Here, the symbols "(" and °) °' are symbols that specify a command or a kana character data string that is converted into kana-kanji. If the character string enclosed in "(" and °) is in katakana, the It is done manually, and in the case of hiragana, the character string is converted to kana-kanji.

In the first example, (kanji city) is a command that instructs to process the following character data string according to the kana-kanji conversion using the kanji specification method, and similarly, in the second example, (bunset city) is a command that instructs to process the following character data string according to kana-kanji conversion using the kanji specification method. This command instructs to process a string of character data according to the Kana-Kanji conversion method. As shown in FIG. 2, many commands for changing the kana-kanji conversion algorithm can be set, including kana-kanji conversion using the kanji specification method and kana-kanji conversion using the bunsetsu specification method.

Here, the command (Tsuujoshori) is normal processing, the command (Jim), (Kikai), (Denki), (Jinmei), and (Chimei) are the names of 9 office machines, 9 electricians, and place names, respectively. This is a command that specifies that a dictionary for a field be searched. The command (doongo) is
This command controls the number of homonyms displayed by weighting the homonyms registered in the dictionary.

The command (horncho switch) is a command that instructs a dictionary search using the so-called longest match method, which deletes one character from the end of an input character string and checks whether the remaining part is an independent word.

The command (SOUATARI) is a command that specifies a search for all homophones registered in the dictionary. The command (Fukugougo) is a command that specifies how many combinations of compound words are allowed during the kana-kanji conversion process.

Corresponding to these various commands C, parameters Pi, 2
．． . . are allocated in advance, and these parameters are stored in the register KPARAM as described above.

In an initial state before the operator inputs a command to change the kana-kanji conversion algorithm, the character processing device of the present invention is initialized to perform kana-kanji conversion processing using, for example, a kanji designation method. Further, once a desired command is specified, the kana-kanji conversion process corresponding to the specified command is performed until another command is specified again.

FIG. 3 is a flowchart showing the processing procedure of the apparatus of the present invention when the above-mentioned command C is input by the operator. When the operator inputs command C in step St, the input command is analyzed in step S2, and step S11. S12.・・・
, branches to S22 and S25. For the command C shown in the second diagram, the corresponding steps Sll,
SI2. ..., S22 are executed, and the value of the parameter P shown in the second figure corresponding to these commands is set in the Kana 1 Fuji conversion algorithm specification register KPARAM.

When a command other than command C shown in the second figure is input, for example, a command indicating °゛line feed°゛, step S
25, and processing according to the type of command is performed.

FIG. 4 is a flowchart showing the processing procedure of the apparatus of the present invention when the operator inputs a character data string using the keyboard KB.

When the character data string is entered manually in step S31, the process proceeds to step S32, where it is determined whether or not the character data string is to be converted into kana-kanji. Here, if the negative determination 1 is, for example, katakana, alphabet input, etc., the process moves to step S33, and processing for katakana input, alphabet input mode, etc. is performed.

On the other hand, if the determination is affirmative, the process moves to step S34. Step S34 is a routine that checks the value of parameter P stored in the kana-kanji conversion algorithm register KPARAM, and according to the determined value of the parameter, step S41. S42. S
43. ..., the process branches to S52.

Step S41. S42. S43, -..., S52 Nioiteha, Tsurezore, command (kanji city l, (bun se city), (tsuujoshori), ..., (fukugougo) processing program P for kanajφ character conversion
CI, PG2. PG3.・, Read-only memory Rol for PGI2! Kana-Kanji conversion is performed according to each algorithm.

When the kana-kanji conversion process corresponding to the preset command is completed for the character data string input in this way, the process advances to step S55, and other processes such as displaying the converted characters on the CRT screen are performed. .

Effects As is clear from the above explanation, according to the present invention, a plurality of kana-kanji conversion processing algorithms are provided, and the kana-kanji conversion processing algorithm that is most suitable for the character data string to be input can be arbitrarily selected as appropriate without increasing the number of keys. This allows you to input strings of character data at high speed.
Furthermore, the efficiency of kana-kanji conversion processing for all input character data strings can be improved, and an inexpensive character processing device can be realized.

It should be noted that the algorithms and commands for the kana-kanji conversion process are not limited to the above 12 types, and of course, any desired number can be set in relation to the storage means.

Furthermore, although it was decided that the processing programs would be provided in the read-only memory ROM, these processing programs would be stored in the disk memory DIjK and transferred from the disk memory DISK to the random access memory RAM when initializing the device or as needed. It may be expanded to

Furthermore, it goes without saying that the shape of the command can be any format as long as the corresponding processing algorithm is determined by inputting a predetermined command.
