Abstract

PURPOSE:To utilize graphic characters of codes for information conversion and graphic characters of a 'KANJI' (Chinese character) code system for information conversion unitedly by processing various codes by a 1st and a 2nd arithmetic means. CONSTITUTION:A CPU 1 accesses a dictionary memory 3 when rendering data is inputted on a keyboard 2 and outputs a specific pattern to a video RAM 4 to display or print it on a CRT 5 or printer 6. When input data inputted on the keyboard 2, etc., are stored as a document, a character data converter 7 converts them into code data of united code system and stores them if the character data are graphic character is code information conversion or graphic characters of the 'KANJI' code system for information conversion. When the stored document is displayed or printed, on the other hand, the code data are reconverted into the graphic characters of codes for information conversion or graphic characters of the 'KANJI' code system for information conversion.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a code system switching device suitable for information processing systems, data communication systems, and word processor sensors.

[Conventional technology]

When using a mixture of graphic characters of information exchange codes and graphic characters of Kanji code system for information exchange.

The code for information exchange is extended to a two-byte representation similar to the Kanji code system for information exchange, and the first byte is expressed as 00g (hexadecimal). 9F from 80+1 which is unused in the code for information exchange! 'IP File from I・EOH
Allocate the first byte of the Kanji code system for K information exchange, and
The second byte is allocated and used from 011 to FFFI.

[Problem that the invention seeks to solve]

However, the conventional technology has some disadvantages, such as increasing the amount of character data and complicating the code conversion method because the code for information exchange and the kanji code system for information exchange are mixed.

In view of these problems, the present invention proposes a code definition device that easily unifies the graphic characters of the information exchange code and the graphic characters of the Kanji code system for information exchange without increasing the amount of character data. The purpose is to

[Means for solving problems]

The present invention provides a first calculation means for performing a predetermined calculation by comparing a code value of a first type of code information with a predetermined value, and a second code information of another type different from the first type. and a second calculation means for performing a tth predetermined calculation on the code value such that the result of the calculation by the first calculation means and the code system are common.

[Effect]

The data exchange cover of the present invention has an information exchange code (for example,
JIS O6220) graphic characters whose code value is less than 80M (hexadecimal), for example, 20P.
Subtract + (hexadecimal number), and if it is 80H (hexadecimal number) or more, for example, KO! If it is less than (hexadecimal number), for example, 40H (16
For example, if it is a graphic character of (J Engineering 5C6226), add 808011 (hexadecimal) to the code value and create a new code. value.

〔Example〕

Therefore, the details of the present invention will be explained below based on the figures and examples.

First, FIG. 1 shows a schematic diagram of a code table.

FIG. 2 is a block diagram of a device showing a word processor that unifies the graphic characters of the information exchange code and the graphic characters of the information exchange Kanji code system of the present invention and uses the t code system. It is a central processing unit that controls the entire system based on the data input from the single-digit keyboard 2, and accesses the dictionary memory 3 in which kana-kanji conversions, symbols, etc. are stored by inputting read data from the keyboard. .

Display the predetermined kanji and symbol patterns on the video ram 4,
It is configured to be displayed and printed by a CRTS or a printer 6. Reference numeral 7 denotes a character data conversion device which unifies the graphical characters of the information exchange code and the graphical characters of the Kanji code system for information exchange, which is a characteristic part of the present invention, and utilizes a constant code system. When the next character data is input using a keyboard or the like and is stored in the document, if the character data is a graphic character of an information exchange code or a graphic character of a kanji code system for information exchange.

They are unified, converted into code data of the next code system, and saved. In addition, when displaying or printing a stored document, code data is reversely converted into graphic characters of an information exchange code or graphic characters of a Kanji code system for information exchange. This is a 7:I temporary storage device that temporarily stores the formatted data converted by the 9-digit character code conversion device.

Next, the operation of the character code conversion device configured as described above will be described in the third section.
This will be explained based on the flowchart shown in the figure.

The graphic character of the information exchange code is the graphic character h of the Kanji code system for information exchange; when input to the character code converter #8, if the data length is hζ1, it will be judged as the graphic character of the information exchange code. 1) If the data value is less than 80F+ (hexadecimal), then (2) subtract 20++ (hexadecimal) and 3
), 40 if 81 or more and less than EOyl ('hexadecimal)
F! (hexadecimal number) is subtracted (4). Also, if it is a graphic character of the Kanji code system for information exchange, it is 8080! (hexadecimal)
(5) The code value is determined as a unified code system. Then, when code data of the unified 9 code system is input, if the code value is greater than or equal to #5AON (hexadecimal number), it is judged as (6) 2-byte code data and 8080 m
(hexadecimal number) is subtracted to obtain (10) graphic characters of the Kanji code system for information exchange, and the code value is 60! If it is less than (hexadecimal number), add (7) 20m (hexadecimal number) (8), 6
AOI over 08! If it is less than (hexadecimal number), 40g (1
Hexadecimal numbers) are added to form (9) the graphic character of the information exchange code. Above are the two code systems, 06220. (! 6
Although H.226 has been explained in detail, the present application is not limited thereto.

〔Effect of the invention〕

As described above, according to the present invention, the first. By using the second calculation means to apply each force to various codes, it is possible to unify the graphic characters of the information exchange code and the graphic characters of the information exchange Kanji code system, and to convert the next character data into It has the effect of unifying the graphical characters of the information exchange code and the graphical characters of the Kanji code system for information exchange, and making it easy to convert to and reverse the code of this code system. .
