PURPOSE:To stabilize the operation of a motor winder by switching on-off a driving source for transferring power to a film winding system by providing a member which is started by a shutter driving member on the completion of the running of a shutter. CONSTITUTION:The circuit of a driving source is provided with a motor M, a power source E, and switch contacts S0-S2 and when the switch contacts S0 and S1 are connected mutually, the motor M turns to wind an exposed film and also to charge a shutter. Once preparations for photographic operation end, the switch contacts S0 and S2 come into contact with each other to stop power supply to the motor M, and a short circuit is formed across the motor M to stop the turning of the motor M suddently. |
