Abstract

PURPOSE:To attain the collective double-width processing for Japanese, English and numeric character strings respectively, by using a collective double-width means. CONSTITUTION:The position where the collective double-width should be instructed in a document stored in a document memory 2 is stored with an instruction given from a document storage instructing means 1. While a designating means 4 instructs a position in said document based on the output of a designated position storage designating means 3 which designates the designated position for double width. A character type collective double-width command means 6 receives the document from the memory 2 in response to a command given from a character type collective double- width command means 5 which delivers a command for collective double-width processing of the same character type. Then the means 6 continues the collective double-width processing until the character type instructed by the means 4 is changed into the character types set before and after said designated position. Then a designated position control means 7 counts the number of characters included in the partial document information processed with the double-width processing. Thus the storage contents of the instruction memory means are replaced in accordance with the number of counted characters.

FIG. 2 shows another embodiment of the character processing device of the present invention.

Here, 11 is a keyboard, and a batch double-width key that instructs to double-width all at once until the character type in the document indicated by the cursor changes to a different character type before and after.For old IK and its fine character processing. It has a key that instructs necessary processing. 12 is a CPU, for example in the form of a microprocessor, which performs control necessary for character processing according to processing procedures stored in ROM 13. This ROM 13 is, for example, the third
This is a read-only memory in which a processing procedure as shown in FIGS.

The mouth AM 14 is a writable random access memory and includes a document memory 15, a cursor register 1G, a display start register 17, and other memory areas 18 necessary for character processing. The document memory 15 stores character information based on input character codes, and also stores information f regarding the stored character information, such as a character flag NFL representing the character type, a leading flag SFL representing the beginning of the same character type, and a character flag SFL representing the beginning of the same character type. A character flag EFL indicating the end of is also stored. The cursor register 16 stores the cursor position.

The display head register 17 stores the character position of the first digit of the line to be displayed.

Reference numeral 19 denotes a display device that displays one line, and one line displays, for example, 20 digit characters and a cursor.

20 is an address signal and data input 8 necessary for controlling each part.
This is a pass line that transfers signals and control signals.

FIG. 3 is a flowchart showing an example of the processing procedure of the apparatus of this embodiment, which is stored in the nOM 13 and executed by the CPI 112.

In FIG. 3, when the device of this embodiment is turned on,
First, proceed to step S1. In this step S1, the state of waiting for the manual input of keys from the keyboard is maintained, and if any key is input, the process proceeds to step S2, the input key is determined, and the double width key BIIK is input all at once. In some cases, the process proceeds to step S3, and in other cases, the process proceeds to step 310.

In step S1O, when a key other than the collective double-width key is operated, characters corresponding to the operated key are processed, and then the process advances to step S1, which is in a key-manpower waiting state.

In step S2, when the batch double-width key old 1 is operated, the process proceeds to step S3, where it is determined whether or not there is a document to be edited. If there is, the process proceeds to step S4; if not, the key The process advances to step S1 in the state of waiting for human power.

In step S4, the type of character on the cursor is determined.

Discrimination of each character type is performed based on the code of each character type, and the character type is determined based on each code.

An example of the subroutine procedure for character type discrimination is shown in FIG. In FIG. 4, first, in step S4.1, a character flag MFL representing a character type, a leading flag SFL representing the beginning of the same character type, and a character flag EFL representing the end of the same character type are cleared to O. Then, step S4
．． In step 2, if it is determined that the code of the target character is a Japanese code (kanji code, hiragana code), the process proceeds from step 54.2 to step 54.3, where the character flag MFL is set to 1. set.

On the other hand, in step S4.2, if the code of the target character is an English character code (English upper case code, English lower case code), the process proceeds to Step 34.4, where the English character code is determined. , proceed to step 54.5 and set the character flag NFL to 2.

Similarly, in the case of a numeric code, the process proceeds from step 34.4 to step 34.6, and the character flag MFL is set to 3 in the next step 34.7.

If the code is for any other various characters, the process proceeds from step 54.6 to step 54.8, where the character flag NFL is set to 4.

Referring again to FIG. 3, when the character type on the cursor is determined as described above in the subroutine of step S4,
By the subroutine of next step S5! Determines the previous character type.

An example of the procedure of this subroutine is shown in FIG. 5. In FIG.
Steps S4.3, S4.5, S4.7, 54 in the figure
．． The character type on the cursor is determined based on the character flag MFL set in step S5.3, S5.5, S5.5, etc. If so, the process is immediately terminated and the process proceeds to step S6. On the other hand, if the character types are different, in steps S5, 6, S5.7, S5.8, etc.
After setting the head flag SFL to 1, the process advances to step S6.

For example, if the character type on the cursor is Japanese, the character flag MFL is set to l in step S4, and the fifth
The code read in step S5.1 in the figure is compared as a Japanese code in step 35.3 according to the determination in step 35.2. As a result, if it turns out that the read code is not in Japanese, step 5
In 5.6, the head flag SEL is set to 1, and the process advances to step S6. On the other hand, if the read code is a Kanji code, the process directly proceeds to step s6.

In step S6, the leading flag SFL is determined, and when the leading flag SFL is set to 1, the next character is determined to be the leading character of the same character type, and the process proceeds to step S7. On the other hand, when the head flag SFL is 0, it is determined that the same character type continues, and the process advances to step S5 to determine the previous character type.

When the beginning of the same character type is determined in step S6,
Proceeding to step S7, here single character double width processing is performed, and double width is applied to each character from the beginning of the character type.

Double-width processing of characters in this case can be performed using existing double-width processing.

When the one-character double-width process is completed in step S7,
Proceeding to step S8, a subroutine for determining the end of the same character type is processed.

An example of a subroutine for determining whether the same character type ends in step S8 is shown in FIG. Step 38 shown in FIG.
1-38.8, step 55.
1-S Use the same discrimination method as in 5.8 to determine the type of character. However, as a result of comparing the character marks in steps S8, 3 to 38.8, in the case of different character types, it is determined that the previous one is the end of the same character type, and in steps 38.6 to 38.8 Set end flag EFL to 1
After setting the value, the process advances to step S9. Step 58
．． 3 to 58.5, if the characters are of the same type, the process is directly terminated and the process proceeds to step S9.

In step S9, the end flag EFL is determined. If the end flag EFL is set to 1 in step S8, it is determined that the characters up to the previous character are of the same character type, and after completing the batch double-width processing of the same character type, step s
Go to 1. On the other hand, if the end flag EFL is 0, it is determined that the same character type continues, and the process advances to step S7 to continue double-width processing.

With the processing flow described above, it is possible to perform batch double-width processing for Japanese, English, and numeric character strings by simply pressing the batch double-width key once.

Note that, in the above, double-width processing is performed for three character types: Japanese, English, and numbers, but the present invention is not limited to this example;
It is also possible to perform batch double-width processing for German, Chinese, etc., and the number of character types is not limited to three, but it goes without saying that any desired type can be used.

[Effects of the Invention] As described above, according to the present invention, double-width batch processing can be performed for Japanese, English, and numeric character strings by a simple operation of pressing the batch double-width key. It is possible.
