Abstract

PURPOSE:To enable excellent printing and to improve the quality of picture, by shortening the print pulse width in case of standard two-writing than that in one- writing. CONSTITUTION:A video signal is inputted to one of line memories 10a, 10b from one input terminal PIX. In this case, the video signal of line is shifted N times to a shift register 2 in M-bit unit by other line memory. The video signal in M-bit transferred to the register 2 is stored in a latch circuit 3 and the video signal in next M-bit is stored in the latch circuit 3. While the video signal in next M-bit is transferred to the register 2, M sets of heating resistors 1a selected at a Y shift register 7 are energized and the electricity sensing recording paper is color developed. In case of the standard mode with twice writing, the clock frequency is twice as much of the case of high quality mode of one writing and the video signal for one line's share stored in line memory 10a or 10b is read out twice for twice writing.
