タの発振が停止するようになした充電停止装置。A flash discharge device comprising a DC-DC converter including a transformer and a switch element, a main discharge capacitor that is charged by the converter and stores electrical and electrical energy, and a flash discharge tube that discharges the electrical energy and converts it into light energy. In the light emitter, when the charging voltage of the main discharge capacitor reaches a predetermined value, the constant voltage member is turned on in order to cancel the control signal of the switch element into a non-operating region using the conduction signal of the constant voltage member that becomes conductive. The switching element is connected to the control pole of the switching element, and the main discharge capacitor is charged to a predetermined charging voltage, so that the switching element is kept non-conductive, and the oscillation of the DC, -DC converter is stopped. This is a charging stop device.
