Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character generator capable of generating and processing a character pattern of an allomorph.

[Conventional technology]

Conventionally, in this type of device, a character code, for example,
Code conforming to JIS (Japan Standards Association) C6226 (JIS C6
226 is currently revised to JISX0208), and is configured so that a character pattern corresponding to an input character code string can be read out, displayed and printed.

Among them, the above-mentioned widely used character codes, that is, character codes conforming to the JIS C 6226-1983 edition, have undergone some changes with the times.

In other words, the JIS C 6226-1983 edition is a revised edition, and corresponds to a new version of the JIS C 6226-1978 edition, which is a step forward.

By the way, there are 6,353 kanji in the kanji code system based on the JIS C 6226-1983 edition, of which 2965 basic kanji characters are divided into a first-level kanji set and the remaining 3388 characters into a second-level kanji set. Each character is arranged in a code matrix composed of 1 to 94 sections and 1 to 94 points.

Kanji code systems based on the JIS C 6226-1983 edition (new JIS code version) currently used are based on the common kanji table promulgated on October 1, 1981 (the Cabinet Order and Notification) and the kanji table for personal names. This is equivalent to JIS C 6226-1978 version changed according to the font change accompanying the enforcement, and JIS C 6226-1978 version (old
75 characters such as 4 kanji, 39 special characters, 32 ruled lines, etc. are added to the JIS code version), and the character form used in the table of some characters is changed according to the font style such as common kanji. There is history.

In particular, as shown in FIG. 6, there are 270 characters including the first level and the second level as shown in FIG.

When the 270 characters are analyzed in more detail, for example, in the old JIS code version, the basket (first level) and the basket (second level) were changed to the basket (first level) in the new JIS code version. Level) and baskets (level 2), new and old ones that only change code from level 1 to level 2 (total 20 characters),
Kuzu (old JIS code version) → Kuzu (new JIS code version), etc. (depending on the type of use of Japanese citizens (personal names on family register, place names, etc.), frequency of use), There are a total of 250 glyph change characters.

Here, the glyph means a figure realized when a character is actually written or printed, and the glyph is a character concept underlying the expressed glyph and identifies each character. It refers to the way of combining stippling as an element. That is, the font is abstract and is specifically realized as a character. Also, from this definition, the character form includes the difference between the typefaces (for example, Mincho and Gothic), and the main problem in this case is the difference in the typeface in which the stippling is combined. As described above, the character shape and the font are used properly.

Thus, the revision from the old JIS code version to the new JIS code version is not completely compatible.

In response to such revisions, the following measures must be taken for the generation of characters in the document editing / creating device.

In other words, in the old and new, for characters whose code only changes from the first level to the second level,
It can be easily handled by changing the index for reading.However, in the new JIS code table, for characters whose glyphs have been changed, the fonts established in the old JIS code version are deleted from the new JIS code version. This causes a problem such as that.

By erasing this character font, for example, when creating an address book, etc., the character font that exists on the manuscript can not be generated by the above device, and the same characters that can be used for the names of people and place names using old characters (Historically of the same origin,
Can be interchanged in the same context and, depending on usage, must be replaced by a set of letters, only one of which is used), implying the honor of the person or the sentiment of the inhabitants of the area. There is a possibility that a situation such as injury may occur.

[Problems to be solved by the invention]

In order to avoid such a situation, the character set in the old JIS code version table can be changed by adding the changed JIS code version, or the old JIS code version character set can be separately arranged in the new JIS code version. Must be supported by having a character set that conforms to.

However, if the modified JIS code version of the character font of the old JIS code version array is added as an external character, characters cannot be generated on models whose external character codes do not match, and compatibility between different models will be lost. The problem of disappearance occurs, and having the old JIS code version character set and the new JIS code version character set separately requires redundant characters in the old JIS code version character set and the new JIS code version character set. Data (thousands of character pattern data common to the character set of the old JIS code version and the character set of the new JIS code version that have not been changed), which greatly increases the cost and, for example, the old JIS code version If an external storage device is provided for each character set and the new JIS code version and the user selects the operation, the external storage device set and the reading time Rent, also occurs problem that significantly inhibited the operability.

The present invention has been made in order to solve the above-described problem. When outputting in the second font mode, a character pattern common to the character pattern in the first font mode is changed to a character pattern commonly used. It is an object of the present invention to obtain a character generator capable of efficiently reading a character pattern according to a designated mode by reading a character pattern of a character that is read and allomorph.

[Means for solving the problem]

The document generating apparatus according to the present invention stores designation means (step (4) in FIG. 4) for designating a font mode, and stores an address corresponding to a character code when the first font mode is designated by the designation means. First reading means (step (8) in FIG. 4) for accessing a first table to read and reading a character pattern at an address corresponding to a character to be output;
When the second font mode is designated by the designation means,
A second table storing addresses corresponding to character codes or identification information indicating that the characters are not allomorphs (address means "0") is accessed and the identification information is stored corresponding to characters to be output. Determining means (step (12) in FIG. 4) for determining whether or not the identification information is not stored in correspondence with the character to be output; Second reading means (step (1) in FIG. 4) for reading a character pattern at an address corresponding to a character to be output stored in the table.
4)), when it is determined by the determination means that the identification information is stored in correspondence with the character to be output, the first table is accessed to determine the address corresponding to the character to be output. Third reading means (step (8) → (12) in FIG. 4) for reading the character pattern.

[Action]

In the present invention, when it is determined that the identification information is not stored corresponding to the character to be output, a character pattern of an address corresponding to the character to be output stored in the second table is read out, If it is determined that the identification information is stored in correspondence with the character to be output, the first table is accessed to read out the character pattern of the address corresponding to the character to be output, and to read out the designated character pattern. Character patterns can be read efficiently according to the mode.
