Abstract
A release mechanism for initiating a camera operation by means of an electromagnetic device which includes a permanent magnet for retaining a release member in an inoperative position, and a solenoid for, upon energization thereof, counterbalancing the magnetic force of the permanent magnet to allow the release member to move to its operating position where it releases an operating member to actuate a camera mechanism, such as shutter mechanism or mirror driving mechanism. With the camera operation, the release member is returned to its inoperative position by an elastic member, and retained again by the permanent magnet for the next camera operation. The elastic member is maintained inoperative at least until the release member releases the restraint on the operating member.
