とを特徴とする写真撮影用ストアボ回路。[Scope of Claim for Utility Model Registration] A power supply circuit having a power supply battery and a DC-DC converter that boosts the battery voltage, a main capacitor charged by this power supply circuit, and a main capacitor whose voltage is boosted to a predetermined voltage. After
Stop the oscillation of the DC-DC converter of the above power supply circuit,
a control circuit that stops charging the main capacitor; a flash discharge tube that uses the main capacitor as a power source; and a semiconductor-controlled rectifier such as a trigger capacitor, trigger transformer, and thyristor. a trigger circuit that supplies a trigger voltage for light emission; and a control voltage supply circuit that supplies a control voltage from the power battery to turn on and off the semiconductor-controlled rectifier, the power supply circuit and the trigger circuit, Connected by a bypass circuit in which a resistor and a diode are connected in series, when the trigger circuit is driven, the residual energy of the trigger transformer and/or the trigger capacitor is absorbed after the semiconductor-controlled rectifier is turned off. A photography storebo circuit, characterized in that the bypass circuit causes the DC-DC converter, in addition to the power supply circuit, to transition from a stopped state to a re-oscillation state.
