Abstract
An electromagnetic release device for a single lens reflex camera in which the force urging a release lever into abutment with a locking lever is released upon completion of a photographing operation. A rotatably mounted release lever is coupled through a pin to a coupling lever and armature which is adapted to be attracted and held by an electromagnet assembly. A release spring is looped around the shaft upon which the release lever is mounted and has a forwardly-extending end which abuts a portion of a rotatably mounted charge lever when the charge lever is in its position at the completion of a winding operation. Upon application of an electrical pulse to the coil of the electromagnet assembly, the armature is released and the release lever kicks a locking lever. Upon completion of a photographing operation, the charge lever is restored and contact between the charge lever and release spring removed to thereby eliminate the force produced by the release spring which urges the armature away from the electromagnet assembly.
