Abstract

PURPOSE: To achieve the simplification of the circuit portions controlling discharge energy and eliminate the need for maintenance during long-term use by prolonging the charging time of a capacitor which gives discharge energy to a flash discharge tube and setting the same at a value contrasting with a flash period.
CONSTITUTION: The output of a rectifier circuit consisting of diodes 6, 7 is applied to a capacitor 10 and the accumulated charges of the capacitor 10 are discharged to a flash discharge tube 11 through a reactor 9 common to a charging circuit and discharging circuit and a reactor 12 inserted to the discharging circuit when the flash discharge tube 11 is triggered. The DC input to a high frequency transformer 5 which constitutes a part of the charging circuit of the capacitor 10 is ON-OFF controlled by the switching transistors 3 and 4 which constitute a switching circuit and the detection circuit of recording paper feed is constituted by a counter 13 which counts auxiliary scanning period pulses, a flash width setter 14 and a concidence judgement circuit 15.
