Patent ID: 7915835

Claim:
An imaging apparatus including a strobe device having a charging circuit of a separately excited oscillation type, the imaging apparatus comprising: a main capacitor in which charge is accumulated to supply power to a strobe-light-flashing unit; a step-up transformer including at least primary and secondary coils; a switching element that performs a switching operation on the basis of a switching control signal to control a flowing or a non-flowing state of a current supplied to the primary coil of the step-up transformer; a rectifier diode that rectifies a flyback pulse generated in the secondary coil of the step-up transformer on the basis of the switching operation of the switching element to supply a charging voltage to the main capacitor; a power-supply-interrupting circuit that is provided between, the step-up transformer and the switching element, and a power supply and that selectively interrupts power supplied from the power supply; a full-charge detection unit that detects whether the main capacitor reaches a fully charged state; and a power-supply-control unit that controls the power-supply-interrupting circuit so as to set the power-supply-interrupting circuit to be in an interrupting state, in a case where the full-charge-detection unit does not detect the fully charged state within a predetermined time after the power-supply-control unit has set the power-supply-interrupting circuit to be in a conducting state and started the switching operation of the switching element.
