Abstract
PURPOSE:To prevent malfunction owing to physical shock without making an electromagnet larger by providing a stop member which retreats from a lever by the operation of a release button for operating the electromagnetic device. CONSTITUTION:A lever 1 which drives the shutter mechanism is provided with an abutting arm 13 projecting to the side of its central part. A reset pin 6 operating cooperatively with a film winding mechanism moves up to the position shown by an alternate long and two short dashes line by film winding operation and after an attraction piece 4 is attracted to a combination magnet 5, it retreats to the solid line position, and the shutter is ready to be released. In this state, the lever 1 is fixed by the magnetic force of a permanent magnet 5b, and the arm 13 is supported by a projecting part 19; therefore, even if shock is given, the easy separation of the iron core of the combination magnet 5 and the attracting piece 4 hence driving of the lever 1 do not occur.
