PURPOSE:To avoid a malfunction of the shutter, by locking the release to prevent the electric conduction to a magnet while a motor is rotating in order to wind and rewind and rewind a film. CONSTITUTION:With a push of a release lever 52, a magnet coupled lever 45 turns slightly clockwise via a spring 46 in case a magnet 33 has on conduction, and a catch 45c engages a hook part 52b of the lever 52. Thus the push of the lever 52 is prevented to give on operation to the shutter. The magnet 33 is constituted so as not to have the electric conduction while a motor is rotating to wind and rewind a film. Accordingly, the shutter never works although the lever 52 is pushed when the motor rotates to wind the film. |
