ADDRESS SELECTION SYSTEM FOR CHINESE-CHARACTER FONT MEMORY

摘要

PURPOSE:To provide a fruitless area in a Chinese-character font memory by providing a calculating means for a starting address from JIS Chinese-character codes when a Chines-character font is stored continuously without waste, and a reading means of reading the Chinese-character font from the calculated starting address. CONSTITUTION:A chip counter 19 which receives address data calculated by a microprogram provided in an ROM6, and a starting address specifying counter 20 are provided. Further, an address record 12 is controlled by a microprocessor 2 to generate a preset signal presetting data, selecting the chip of a Chinese-character font memory 9, in a chip counter 19, a preset signal presetting data specifying the memory in the starting address specifying counter 20, and a count-up signal increasing the contents of a specifying counter 21 for an address in a character by +1 for each time.
