Abstract

PURPOSE: To generate an expanded character pattern by a character generator for a basic character pattern, by performing processing by storing an expansion-value code and expansion transition code in refresh memory RFM which is stored with characters to be displayed in the form of codes.
CONSTITUTION: In addition to character codes, RFM2 is stored with an expansion- value code expressing expansivity and an expansion transistion code. Decision circuit 7 decides upon which one of codes, a character, expansion value and expansion transistion, a information read out from RFM2 is, and under its output control, it is inputted to one of character generating circuit 4, expansion value temporary-memory circuit 8 and expnasion-value transition temporary-memory circuit 9. According to the notice of circuit 7, selector circuit 10 selects either of outputs of circuit 8 and of expansion circulating memory 11 and outputs it to memory 11 and expansion processing circuit 12. Circuit 12 knows the expansivity indicated by an input from circuit 9 and that from circuit 10 and which part of chatacter is displayed on the line, and indicates raster number information to circuit 4 by the content of a raster counter supplied from timing circuit 3, thereby displaying it on CRT6 at a fixed expansivity.
