ABSTRACT:
An electromagnetic release mechanism for a camera in which a release member is returned to an energized and locked position through a spring which is energized and deenergized in response to rotation of a cam which is rotated upon performing a film winding operation. A rotatable release locking member has a forked end in which is engaged a first end of a release member and a cut in which an end of a slidable release drive member is lockably engaged. A movable member is mounted on the other end of the release member at a position to be attracted by an electromagnet the force of which is reduced by a coil wound thereon when a current is passed through the coil upon the start of a release operation. A spring joins the release member to one end of an arm which is rotated at its center and which has its other end riding upon the cam surface. With this construction, it is unnecessary to provide a separate mechanism for forcibly returning the release member after a release operation has been accomplished.
