Abstract

PURPOSE:To lock a release member securely by providing a locking means of locking the release member when a moving member which starts moving on the completion of the running of a shutter starts moving. CONSTITUTION:When switch contact pieces S3 and S4 are connected mutually and switch pieces S0 and S1 are also connected mutually, a motor M turns to advance an exposed film and also to charge a shutter. Once photographic preparations end, the switch contact pieces S0 and S2 are connected mutually to stop power supply to the motor M, and a short circuit is formed across the motor M, which then stops turning suddenly. The switch contact pieces S3 and S4 are released when a release lever is pushed down.
