CORRECTION OUTPUT SYSTEM FOR PATTERN ERROR OF 'KANJI' (CHINESE CHARACTER) GENERATOR

摘要

PURPOSE:To output a correct character pattern, by detecting an error in the character pattern in a character generator, generating or entering a corresponding correct character pattern, and storing the correct pattern in an RAM. CONSTITUTION:The titled system consists of a CPU 1, a printer controlling device 2, a printing driver mechanical part 3, and a microprocessor 4. A correction output routine controls an error check routine for a character generator (CG) pattern and the output of a correct CG pattern instead of an incorrect CG pattern. An RAM 8 includes a work area necessary for the control of a printer. Only the ''kanji'' (Chinese character) code of a CG pattern of which bit error has been detected out of the CG patterns in a CG ROM 7 is previously registered in a CG pattern controlling table 9a in the RAM 8 and simultaneously a correct CG pattern corresponding to the ''kanji'' code is stored in a CG pattern file 9b.
