Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character output method that receives input character codes and control codes and outputs characters developed into image dot information.

[Conventional technology]

Conventionally, this type of kanji output device usually accepts only one type of kanji code, and the external device converts the code to match the kanji output device, or the output device converts the code to match the kanji code on the external device. Code conversion was done on the side. However, even in the latter case, JIS
C6226 (hereinafter referred to as JIS6226) code,
For example, convert rX"2121"J to JEF, KEIS:I-do, for example rX'AIAIJ.
There are things that can be simply converted, and things like converting JIS6226 code to shifted JIS code. Furthermore, many of the codes could be converted by executing certain procedures, such as Kanji codes in O5 (operating system) for microcomputers.

[Problem that the invention seeks to solve]

Conventional kanji output devices are configured as described above, so it is necessary to register another character in the kanji code part of the already registered character, or to basically convert it to JIS6226 code like the IBM kanji code. There were problems such as the inability to support code systems that cannot be automatically converted, and the inability to fully utilize the performance of a kanji output device capable of high-speed printing and high-speed display.

This invention was made to solve the above problems, and it develops font patterns according to each kanji code system stored in an external storage device, and also allows characters to output desired font patterns at high speed. The purpose is to obtain an output method.

[Means for solving problems]

The character output method according to the present invention reads each font pattern according to the code data of each Kanji system from an external storage means in which each font pattern is written in advance and writes it into a font memory.

[Effect]

Interprets the code data of each kanji system input from an external device, and writes the font pattern of the interpreted kanji system into the font memory.

〔Example〕

FIG. 1 is a block diagram illustrating a character output method according to an embodiment of the present invention. Reference numeral 1 denotes a receiving interface, which receives code data from an external device. Reference numeral 2 denotes an operation unit that commands control data, and 3 a microprocessor for processing input data, which interprets code data input through the interface 1 and control data commanded from the operation unit 2, and processes the data. 4 is a page memory that stores one page of character data for display, printing, etc. Reference numeral 5 denotes a microprocessor for output data, which reads font patterns from a font memory 6 and writes them into a frame memory 7. Reference numeral 8 denotes an external storage device in which font patterns of various kanji systems are stored in advance; Each font pattern is written into the font memory 6 in accordance with the command or the font designation from the operation unit 2.

Next, the operation will be explained.

The microprocessor 3 reads the necessary font pattern from the external storage device 8 in advance when the power is turned on or according to an instruction from the operation unit 2, and writes it into the font memory.The code data input from the external device is sent to the interface 1.
is input to the microprocessor 3 via. The microprocessor 3 interprets the input data, performs printing processing such as retrieving a print record, and writes the character code of the character to be printed in the form of an internal code to the page memory 5. The internal code is shown in FIG. In the case of 1-byte code data that consists of 3 bytes and outputs alphanumeric-kana characters, the first byte of the 3 bytes is set to ``x'00'', for example, and kanji characters are output. In the case of a 2-byte code, the first byte should be set to ``x'01'', for example.
'', that is, rX'oo'J for 1-byte code data that outputs alphanumeric characters and kana characters.

After rX'00"J, add an internal code corresponding to the 1-byte code data of the Kanji system input from the external device. If it is a 2-byte code that outputs Kanji characters, the first 1 byte is written as rX' After 01'J, an internal code corresponding to the 2-byte code data in the Kanji system input from the external device is added.

The microprocessor 3 is a microprocessor that receives and receives a page break code, or closes the page memory 4 when data for the number of lines on one page is input, and passes the code data to the microprocessor 5 for output. 5 takes out the code data from the page memory 4 3 bytes at a time, distinguishes between the above-mentioned 1-byte code and 2-byte code based on the first byte, and uses this distinction to frame the image dot information read from the frame memory 7. The microprocessor 5 reads out the font pattern (image dot information) stored in the font memory 6 and writes the image dot information in the frame memory 7 according to the address calculation. Configure by page.

When registering characters such as external characters and logos.

The microprocessor 3 determines the registration sequence of a certain character, converts the input code data into internal data through a legitimate process, and then operates the font memory 7 to register the character (image dot information). )
is performed on a predetermined area. In the external storage device 8 and font memory 6, in areas that are not registered, an undefined character pattern is written to indicate that, for example, a pattern that combines a triangle and the letter U. Therefore, character registration is performed using the code rX'oo00. "J~Code rX" FF
You can freely perform up to FF'J, processor 3.5
When print data is input from an external device or when an internal code is received, it is possible to omit the judgment as to whether or not the received character is registered.

Next, the character output method of the present invention will be explained with reference to FIG.

FIG. 3 is a diagram explaining the font patterns of each kanji system written in the font memory 6 shown in FIG.
21 is JIS6226 code system, 22 is shift JIS
Code system, 23 is JEF (KEIS) code system, 2
4 is the IBM Kanji code system.

As shown in this figure, for example, the external code for the character "A" is "x'302" in JIS6226 code system 21.
1', and rX' in Shift JIS code system 22.
889F'J, t-k in JEF code system 23
rX"BOAl'J, and in the IBM Kanji code system 24, it becomes rX'4867'. In this way, there are some differences in the external codes of characters used for each kanji system. Therefore, when a command to change the code system of characters including kanji characters from, for example, JIS6226 code system 21 to, for example, IBM Kanji code system 24 is issued through the operation unit 2 or initial settings, the processor 3 receives the command from the external storage device 8. Next, the microprocessor 5 reads the internal code "x'014867'J" written in the page memory 4, and reads the internal code rX'. 014867 Read the t67t7 pattern for ``J'' from the font memory 6 and store it in the frame memory 7.
Here, when a print command is issued, the character "A" is output.

In this way, the processors 3 and 5 write the font pattern read into the font memory 6 into the frame memory 7 without converting external codes into internal codes for each kanji system, allowing high-speed printing. Image dot information can be transferred to other output devices without reducing throughput.

〔Effect of the invention〕

As explained above, in this invention, each font pattern is read from an external storage means in which each font pattern is written in advance in accordance with the code data of each kanji system, and written into the font memory. This method has the advantage that the operation of converting external codes into internal codes for each system can be omitted, and the font patterns of each Kanji code system can be output at high speed.
