Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character processing system (for example, a Japanese language processing system), and in particular, a central processing unit provides a character code to a Japanese language processing device, and the Japanese language processing device receives the character code. The present invention relates to a Japanese language processing system that outputs characters by converting them into character patterns.

2. Description of the Related Art In recent years, various types of Japanese output have been studied in information processing systems in order to make the output of electronic computers easier to see and use.

Japanese has an extremely large number of kanji, including katakana, katakana, and the alphabet, and as a result, the storage capacity required to store kanji and other patterns is enormous, which is always a bottleneck in processing Japanese. In conventional character processing systems, for example, a character pattern memory is provided in a kanji line printer, character codes from a central processing unit are converted into character patterns using the character pattern memory, and character patterns are output. When a character code that does not exist in the character pattern memory is given to the device (i.e., when it is a non-standard character)
, the character pattern was stored in the character pattern memory from the character pattern file and processed.

In such a kanji line printer, the foreign character is valid only while printing one page, and even if the foreign character exists in the print data of the next page, the character pattern corresponding to the foreign character is transferred to the character pattern file again. It was necessary to store it in the character pattern memory. One of the objects of the present invention is to eliminate the above-mentioned waste and perform efficient character processing, and furthermore, to enable the above-mentioned non-standard character processing to be performed automatically without the user being aware of it. be.

The purpose of this is to obtain character patterns by referring to the character pattern memory to obtain character codes given by the central processing unit, so that character processing systems including Japanese language processing units that output characters can be used to create character patterns for basic characters. A basic character pattern memory that stores character patterns, a character set management memory that stores character patterns for character sets unique to each job other than the basic characters, and a character set management memory that stores character patterns for a large number of characters required for Japanese processing. It is equipped with a pattern file and a logging file, and when starting an arbitrary job, the character pattern stored in the basic character pattern memory and the character pattern unique to the job stored in the character set management memory are stored in the character pattern memo river. If the character pattern corresponding to the character code from the central processing unit does not exist in the character pattern memory, at that point the character pattern is output according to the character code from the character pattern file. This is achieved by storing the corresponding character pattern in the character pattern memory and continuing to output it, as well as storing the character code in the logging file in association with the job being executed.

The present invention will be described in detail below with reference to the drawings.
2 is a main memory; 3 is a character set memory that stores character sets (a memory that stores arbitrary character patterns added by the user);

), 4 is a channel processor that processes data input/output to the central processing unit 1, 5 is a Japanese language processing device that performs Japanese language processing, 6 is a memory unit including a character pattern memory,
6-1 is an output character code memory, 7 is a floppy disk that is a basic character pattern memory, 8 is a character output section,
Reference numeral 9 denotes a character pattern file (a file in which dot patterns of characters required by the user are registered) and a logging file (a file in which ID, time, missing character codes, job names, etc. are logged). Next, the operation will be explained.
The central processing unit 1 normally executes a group of instructions (program) stored in the main storage device 2.

When a data set to be output is prepared in the main storage device 2 or in an external storage device (not shown), the channel processor 4 is activated by specifying the area. This data set is a collection of character codes, and the Japanese language processing device 5 converts the character codes sent via the channel processor 4 into character patterns using the character pattern memory 6, and outputs the characters at the output unit 8. become. Conventionally, there are kanji output devices that create and output kanji patterns from given character codes.

In this case, the kanji pattern is created using the pattern stored in the memory, and for the kanji (character pattern not found in the kanji output device) pattern, a kanji identification code called a kanji shift code is set by the user. The external character pattern is transferred to a device (for example, a central processing unit) that controls the kanji output device according to the code. However, this custom character pattern is only effective for printing one page, and when one page is printed, the custom character pattern is reset, and the custom character pattern is transferred again to a new page. Processing efficiency was poor. The character processing device according to the present invention performs the following operations.

■ Turn on the power to the Japanese language processing device 5. When the power is turned on, character patterns (e.g., equivalent to JIS 1st level) stored in the floppy disk in the Japanese language processing device 5 are stored in the character pattern memory 6. The character pattern memory 6 consists of a basic character pattern memory 7 (JISI) and business-use character patterns, and this first level has 2965 characters.
It is said to cover more than 99% of characters used in daily life. (excluding person's name) ■ The character set memory 3 stores character patterns other than basic characters that will be used in the job in correspondence with the famous job.

Prior to job execution, the central processing unit 1 operates to store the character set corresponding to the job stored in the character set memory 3 into the character pattern memory 6 of the Japanese language processing device 5. The character set corresponding to the job is stored in this character set memory, including the kanji code and basic character pattern used in the job. (for example, JIS 1st level), select kanji codes that are not in JIS 1st level, and select the kanji code and its kanji pattern (obtained by referring to character pattern file 9). This is achieved by creating a set. (2) The Japanese language processing device 5 starts outputting in response to a command from the central processing unit 1.

The command specifies an address area in which character codes to be output are stored, and the Japanese language processing device 5 outputs a predetermined amount of character codes in the area to the character code memory 6-1.
The character code is converted into a character pattern by referring to the character pattern stored in the character pattern memory 6, and outputted, that is, printed. If there is any kanji code data received by the Japanese language processing device 5 that is not stored in the character pattern memory 6, an interrupt called a unit check is caused to the central processing device.

When this interrupt occurs, the central processing unit 1 receives sense information from the device that caused the interrupt as a normal operation. In this sense information, the central processing unit 1
It is shown that the CPU handled an undefined code, and the central processing unit 1 knows that there was an undefined code. (2) The central processing unit 1 extracts a character pattern from the character pattern file 9 using the undefined code as a key, and transfers it to the Japanese language processing unit 5.

Then, the Japanese language processing device 5 resumes printing. Note that this character pattern file 9 stores character patterns of approximately 13,000 characters. (2) During the processing in (2), the central processing unit 1 stores the undefined code in the logging file 10.

Thereafter, the above operations are repeated as necessary, and the Japanese language processing device prints. and logging file 1
The undefined code stored in 0 (associated with undefined job information) is additionally registered in the character set of the corresponding job by referring to the character pattern file 9 at a predetermined time. Processing is performed. This predetermined period may be every fixed period of time or every time each job is completed. In the above explanation, the character set memory 3, character pattern file 9, and logging file 10 are treated as different peripheral devices, but of course the effects of the present invention will not be affected even if they are configured as one large-capacity peripheral device. There is no difference.

Furthermore, although the above example shows the case where there is only one Japanese language processing device 5, the character set memory 3, character pattern file 9, and logging file ID may also be provided in common for multiple Japanese language processing devices. I don't buy it. The processing effect of the Japanese language processing device 5 also does not deteriorate significantly. Furthermore, in the above example, the character pattern file 9 and the floppy disk 7 are different peripheral devices, but the Japanese language processing device 5 stores, for example, character patterns for 13,000 characters including basic character patterns.
The download and log file 10 may be provided as a large capacity disk or the like.

In this case, it is necessary to store the basic character pattern and the job-specific character pattern into the character pattern memory 6, but since the external character processing can be performed within the Japanese language processing device, the load on the central processing unit 1 itself is reduced. becomes possible. As described above, according to the present invention, since the character set memory is used, efficient processing can be performed, and furthermore, since the character set memory is dynamically updated, the processing efficiency is further improved.
