Character display device

As this is a public information case, the full text was not included.

5 is an explanatory diagram showing the relationship between the character display and the character code in the V RAM 3 in the embodiment.

6 and 7 each show an example of the relationship between data and display characters in the V RAM.

Claims (7)

A character display apparatus for displaying various characters, comprising: (a) a storage unit for storing a character code for designating each character and attribute data for displaying the attributes, and (b) a shape data corresponding to an alphanumeric character in advance; The first character generator, (c) a second character generator for storing the character data corresponding to the Chinese character in advance, and (d) a character code read out from the storage unit according to the scanning of the display surface independently A judging section for judging whether or not the indicating data is two or more characters; and (e) when displaying alphanumeric characters, the character code read out from the storage section based on the judgment result of the above-mentioned judging section. When the corresponding character data is read from the first character generator and the corresponding character is displayed by the attribute data accompanying the character, the received character is displayed. A character display device comprising reads the shape data corresponding to the read-out character codes from the storing unit on the basis of the character generator from the second control unit for displaying the Chinese character in the art attribute incidental to the character code the results. 2. The character code according to claim 1, wherein (a) a memory for storing at least a character code indicating a character at least one or two, and (b) a character code for extracting said character code from said memory in accordance with a scan of a display surface. A drawing unit, (c) a determining unit which determines whether the character code extracted by the character code extracting unit is a data that independently characterizes or indicates data by two or more characters, and (d) character data of the character; The character indicated by the character code by referring to the number necessary for designation of the character, the character generator stored in advance and the character code inserted by the character code extracting unit based on the determination result of the determination unit described above. An address generator which creates an address of the character generator in which the character data of the character is stored, and (f) based on the character data read out from the character generator in correspondence with the created address. The character display device having the dot creation unit that creates a serial data deutteu data for display, and displays the character on the basis of the serial dot data. 2. The character coder of claim 1, wherein the display controller reads out the character code read out by the display controller in synchronization with an access of the display controller that reads the character code from the memory in accordance with a scan of the display surface serving as the character code extractor. Character display apparatus according to claim 2. The memory according to claim 1, further comprising: (a) a memory for storing one or two or more characters and character data paired with each of the above-described character codes; and (b) the memory described above according to a scan of the display surface. A judging section for determining whether the character code read from the character is data indicating a character alone or data indicating a character with two or more characters, (c) a character generator for storing in advance the character data of the character, and (d) A shape data reading means for reading out the shape data of the corresponding character from the above-mentioned character generator with reference to the number of character codes necessary for designation of the character on the basis of the determination result of the determining portion; According to the judgment result, the attribute data paired with the second and subsequent character codes of the character code specifying two or more characters are recognized as the extended attribute data, and the extended attribute data and the first Here a character generator having a control attribute is to control the display character represented by the attribute data in the code and the pair 5. The character generator as claimed in claim 4, wherein the attribute control unit has means for switching the validity / invalidity of the recognition operation of the extended attribute data. The character generator according to any one of claims 2, 3, and 4, wherein the character code is a one-byte character code indicating a half-width display character or a two-byte character code indicating a full-width display character. The character generator according to claim 6, wherein an alphanumeric character is set as the half-width display character and a Chinese character is set as the full-width display character. ※ Note: The disclosure is based on the initial application.
