Abstract

PURPOSE: To light a flash lamp in many times in a short time, and yet to extend the lives of capacitor units, by successively discharging a plurality of capacitors to one flash lamp in a flash fixing apparatus.
CONSTITUTION: When switch S3 is turned on by a charge start signal, AC power supply voltage is raised with transformer T2 via switch S3, full-wave rectified with full-wave rectifying circuit REC, and applied to capacitor units C2 and C3 via diodes D2 and D3, respectively. Trigger circuit TC provides a trigger signal to flash lamp L2 in response to a lighting signal with predetermined cycle. On the other hand, combinational circuit LC receives the lighting signal and alternately provides gate signals t1 and t2, turning on thyristors SCR1 and SCR2, respectively and alternately discharges the charges of capacitor units C2 and C3 to flash lamp L2, thereby permitting lamp L2 to light in many times in a short time.
