Abstract

PURPOSE: To realize the output of high-accuracy timing signals by generating previously the plural number of pulse signals featuring the same frequency and different phases and then delivering selectively the pulse signal which turns first to the phase mode in the form of the timing signal after generating the input pulse.
CONSTITUTION: The laser beam is modulated based on the print information and by optical modulator 4 provided at the path of laser beam 3 from beam source 2, and the image is formed on recording medium 6 through reflection via rotary polyhedral mirror 9. Photo detector 12 is installed to drum 5 of medium 6 to detect the scanning timing of scanning beam 11, and thus beam 11 is detected through detector 12 to deliver pulse P1 in the form of the scanning timing information of beam 11. Pulse P1 is then applied to timing signal generator 13, and timing signal S1 is applied to character generation control circuit 14 driving modulator 4 from generator 13. At the same time, reset pulse P2 is generated through circuit 14 with every scanning of beam 11, and generator 13 is reset to generate the high-accuracy timing signal through circuit 13.
