Abstract

PURPOSE: To enable a display unit and printer to share a character generator by providing two memories stored with character codes assigning addresses of the character generator and then by using the character generator in a time-division mode.
CONSTITUTION: Microprocessor 1 and main memory 2 are connected to data bus 3 to constitute CPU and to bus 3, refresh memory 6 stored with character codes as many as one display screen and buffer memory 16 stored temporarily with character codes to be printed out on a form are coupled. Character codes outputted from memories 6 and 16 are made to correspond to addresses of character generator 8 so as to control display control part 7 and print control part 17, and character codes are given to addresses of generator 8. Then, the output of generator 8 is converted into a series signal by parallel-series converter 9 and branched to picture circuit 10 and print circuit 20, and generator 8 is used in a time-division mode to share generator 14 between display unit 10 and printer 14.
