Abstract
A single lens reflex camera includes an electromagnetic release device in which a locking mechanism including an armature is moved to an inoperative position under a spring force to release the locking of a drive member when a solenoid generates a magnetic force to cancel the magnetic attractive force of a permanent magnet, which attractive force attracts the armature to a core, thereby maintaining the locking mechanism in an operative position. The drive member thus released actuates an exposure initiating mechanism of the camera to start exposure operations. In response to the completion of the closing of the shutter, a signal member moves to release a spring loaded resetting member from locking by another locking mechanism. The resetting member thus released resets the first locking mechanism to the operative position against the spring force as well as resets the drive member to a position in which the drive member is capable of being locked again by the first locking mechanism which has been reset to its operative position.
