a serial/parallel data converter that converts the three primary color signals into parallel data of a predetermined unit in synchronization with the horizontal and vertical synchronization signals; and accumulating the parallel data output from the serial/parallel data converter. Accordingly, screen 1 of the CRT
A memory capable of storing an amount of video information for one frame, and a memory synchronized with the horizontal and vertical synchronization signals to sequentially write parallel data output from the serial/parallel data converter into the memory in the predetermined units. an address counter that generates a write command signal that specifies an address to be stored in the memory; a read counter that generates a read command signal that reads out the parallel data stored in the memory in a predetermined unit; A parallel/serial data converter that converts read parallel data into serial pulse data, and □ synchronizes with the predetermined main scanning period and sub-scanning period of the print drive mechanism and corresponds to one bright spot to be printed. an oscillator that generates a timing clock pulse signal, and supplies the timing clock pulse signal output from the oscillator as a driving pulse to the read counter and the parallel/serial data converter,
