駆動装置。[Claim for Utility Model Registration] An excited electromagnet that is energized in a direction that cancels the magnetic force of a permanent magnet to operate a shutter mechanism component that constitutes a part of the shutter mechanism, and that generates a fusing force for a predetermined period of time. A demagnetizing electromagnet that attracts and holds a shutter mechanism constituent member different from the shutter mechanism constituent member and is demagnetized after a predetermined period of time; and a capacitor that accumulates charge for supplying current to the excitation electromagnet. The capacitor, the excitation type electromagnet, and the demagnetization type electromagnet are connected in series to form a series circuit, and the series circuit is connected to a DC power supply, and the excitation type electromagnet and the demagnetization type electromagnet are connected in series. An electronically controlled shutter drive device for a camera, characterized in that energization is controlled by a single energization switch element.
