Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a document processing device suitable for creating, displaying, and printing documents containing a mixture of full-width and half-width characters.Recently, Japanese document processing devices have made remarkable progress. New models are announced by each company every year. The characters handled by these document processing devices include half-width characters whose outer frame size in the arrangement direction of nine full-width characters is half the size of a full-width character, and double-width characters whose outer frame is twice the size of a full-width character. Consisted of. For this reason, when displaying or printing half-width characters in a document containing a mixture of full-width and half-width characters, various methods for specifying half-width characters have been devised.

The first method is Its (Japanese Industrial Standard) 62 shown in Figure 1.
This is the method shown in No. 25. In FIG. 1, 1 is a character code expressed in 2 bytes, and the full-width character 1 is a half-width designation code of the control character code. The character code following this half-width designation code 2 is treated as a half-width character. The second method has the data structure shown in FIG. In Figure 2, 3 and 4 are among the control character codes.
The half-width start code and half-width end code are shown in order. In this case, a string of character codes 1 existing in an area surrounded by half-width start code 3 and half-width end code 4 becomes a half-width character string. However, although the above method has the advantage that the same code can be used for full-width characters and half-width characters, it is necessary to add a control code to specify half-width characters. This means that each time you specify a half-width character, the document data becomes longer by the code that represents it. In particular, if all of the documents are half-width characters in the first method, the amount of data in the document will be doubled. Also, the first method, the second method
In any of the above methods, control codes 2, 3, and 4 must be checked during document editing processing (insertion, deletion, movement, copying, etc.), resulting in increased processing complexity and processing time.

As a result, a burden is placed on the entire processing system (hardware, software, etc.).

Purpose of the Invention In view of the above-mentioned problems, an object of the present invention is to reduce the burden on the entire processing system of a document processing device by mixing full-width characters and half-width characters in the same document without the presence of control character codes. do.

Structure of the Invention The present invention provides a display printing means for displaying and printing a document, and a 2-byte code that does not match either a graphic character code or a control character code that consists of 2-byte full-width characters, into a 1-byte code. Using a half-width character pair code assignment means for assigning to a half-width character pair composed of two half-width character inscription codes, and a 2-byte half-width character pair code and a 2-byte graphic character code assigned by the half-width character pair code assignment means. This is a document creation device that is equipped with a document creation means that performs document creation processing, and is capable of ensuring that the length of each character when displayed and printed matches the code length of the corresponding character when full-width and half-width characters are mixed in the document. This is what I did.

DESCRIPTION OF EMBODIMENTS FIG. 3 shows an embodiment of the present invention. Reference numeral 11 denotes a document processing device, which performs data processing necessary for document creation, such as inputting and editing character codes of documents. A display device 12 displays the document currently being input or edited. A printing device 13 prints the document currently being input or edited. 14
is a storage device that stores documents created by the document processing device 11.

FIG. 4a is an assignment diagram of character codes used in this embodiment. In the 11S6220 7-unit code system, character codes from 21 to 7E in hexadecimal are assigned, and control character codes and the like are assigned to other areas. Ji362
In No. 26, the graphic character codes used to describe normal Japanese language sentences in 2-byte format are assigned to hexadecimal numbers 2121 to 7E7E, and control character codes and the like are assigned to other areas. However, in this 2-byte code, the most significant bin (MSB) U of each byte is not defined. Therefore, the graphic character code and control character code consisting of 2 bytes are ORed with 8080 in hexadecimal,
By shifting the area, it can be separated from the character area of the 7-unit code system defined in Ji36220 on the code table. In FIG. 4a, 41 is a half-width code area in which characters defined by JiS6220 are half-width, and 42 is a JiS6220-defined half-width code area.
This is a graphic character code area in which the characters defined in S6226 are double-byte characters and are shifted on the code area.

Furthermore, in order to facilitate the handling of character data, all character codes handled by the document processing apparatus of the present invention are defined to consist of 2 bytes. Figure 4 shows a 2-byte graphic character code, and C handles a half-width character code as a 2-character pair.

The above explanation has shown the possibility of a mixture of codes for full-width characters and half-width characters. However, as shown in FIG. 4a, two areas in which 21A1 and 7EFE and AI 21 and FE7E are two diagonal points in hexadecimal notation are not defined.

Therefore, in the next embodiment, these two areas are expanded and defined. That is, there are 51 extended half-width character code areas and 52 extended graphic character code areas in FIG. 5a. In this case, the double-byte character code consisting of 2 bytes is shown in Figure 5b.
The pair of half-width character codes is shown in Figure 6C. That is, the lower byte MSE63 becomes a bit that can be used freely by the user, and can be defined as an attribute of a character code such as an underline. Further, MSB54 of the upper byte serves as a flag to distinguish between a full-width character code and a half-width character code. In the above description, the hexadecimal number 8080 is used as the logical sum for the full-width character code, but in reality, the logical sum may be taken as 8000.

Using the above code, document creation processing is always performed using 2 bytes as one character unit. If it is a half-width character, two characters can be edited at the same time (insertion, deletion).

moved, copied, etc.). The only exception is when only one half-width character is entered, but this can be handled by automatically adding a half-width space before or after a pair of half-width characters.

Effects of the Invention As described above, the present invention shifts full-width characters in the code system and treats half-width characters as pairs of two characters.
This allows full-width and half-width characters to coexist in a document without using special control codes, and has the following effects: 01, the length of each character when displayed and printed is Since the code length matches the code length, the editing process 1 displaying and printing of the document becomes easy.

2. Even if full-width characters and half-width characters coexist, there is no need for control characters to distinguish between the two, so the area for storing documents can be reduced.

3. Since half-width characters are handled as a pair of two characters, the character code length is a fixed length of 2 bytes. Therefore, an odd number of half-width characters will not exist in a document. Therefore, the character strings in the text are not shifted by half-width characters, and a beautiful character arrangement can be obtained when displayed or printed.
