Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to a character pattern output device used in personal computer systems and the like.

[Technical background of the invention and its problems]

In a personal computer system or the like, when displaying letters, figures, or so-called characters, a configuration as shown in Figure 1 is generally used. That is, the CPU 1 stores in advance a large number of codes (character codes) corresponding to each character, gives the address data 2 to the character memory 3, and thereby transfers the character code 4 read from the character memory 3 to the character pattern memory 5. By specifying the address by specifying the address, output the character pattern 6 as desired, and write it as, for example, ・C'R', T
74 is displayed on Play7.

This configuration has a one-to-one correspondence between the character code in the character memory 3 and the character pattern in the cow Yarakupa and turn memory 5. Therefore, in order to increase the types of character patterns that can be output, it is possible to increase the number of character patterns that can be output. The capacity of not only Memo 1 and 5 but also character memory 3 has increased, and the overall memory capacity has increased rapidly.

Also, in response to input from CPU'1 through processing, a certain specified +Q+a? In some cases, it may be necessary to convert and output a character/pattern (for example, to output a kana as a single character). The method used was to write a kanji code in the area. However, this method cannot be assembled using kanji, so the program
Purpose of Tribute Invention], 1. , Ic, , (7) Invention 0 Purpose: 7 To be able to output a wide variety of character patterns with as little memory capacity as possible, and to only require simple character codes that are convenient for program processing, etc. An object of the present invention is to provide a character pattern output device that provides a character pattern.

[Summary of the invention]

The present invention provides a code converter for converting a character code output from a character memory into another code, and furthermore, a character code that is not converted and a character code that has been converted are respectively addressed and are different from each other.

The first step is to output different types of character patterns. It is characterized by having a second character pattern memory.

〔Effect of the invention〕

According to this invention, it is possible to output two or more different character patterns corresponding to the same character code in the character memory, that is, the character memory can be shared for each character pattern memory, so that the output is possible. Even if the number of character patterns sh increases, the overall memory capacity can be relatively small. Therefore, it is advantageous in terms of cost.

Further, by storing character codes in the form of codes (for example, ASCII codes) convenient for program processing in the character memory, and obtaining kanji codes and the like using a code converter, operation becomes simple.

[Embodiments of the invention]

FIG. 2 shows an embodiment of the present invention. CPU
The steps from 11 to 12 in which address data 12 is given to character memory 13 and character code 14 is read out from character memory 13 are the same as the conventional device.

The character code 14 output from the character memory no. 3 is selectively supplied to an eleventh character pattern memory 16 and a code converter 17 by a switch circuit 15. The code converter 17 inputs the character code 14 (f, etc. 0) via the switch circuit 15:
] - Convert to 1B and give it to the second character pattern memory 19 as address data. Zunawab,
The first character pattern memory 16 is directly addressed by the character code 14 and contains character patterns 20. For example, a kana pattern is output, and the second character pattern memory 19 stores a character code 147.
2. Addressed by the converted code 18, another character pattern 21, such as a Kanji pattern, is output. These character patterns 20.21 are switch 2
2 and supplied to an output device, such as the C'RT monitor 23 or a printer.

In this way, different character patterns 2 are created based on the character codes output from the same character memory 13.
0.21 can be output. Note that the switch circuit 15 and the switch 22 may be controlled by commands from the CPU 11, for example.

In the above explanation, the character patterns 20 and 21 are respectively referred to as a kana pattern and a kanji pattern, but these are just examples. Alternatively, the fonts may be different, such as 20 being an uppercase alphabet pattern, 21 being a lowercase pattern, or even 20 being a Mincho font and 2 being a Gothic font. In short, 20 character patterns
．． 21 may be in a relationship of different>1 class.

Furthermore, the conversion from the character pattern 20 to the Senyarakuta pattern 21 by code conversion of the code converter 17 does not necessarily have to be done character by character, but can be done by adding fingers to a certain area (section) and converting the area at once. For example, it may take the form of converting a kana pattern to a kanji pattern.

For example, it is also possible to add a code converter and a character pattern memory to output more types of character patterns for the same character hood.
