Abstract
Apparatus for stopping the motor of a motor drive mechanism in a camera is disclosed. The motor drive mechanism is of the type in which the motor is started driving by a film winding start signal and is stopped by a signal obtained at the moment of a film winding end signal being produced. Apparatus for stopping the motor according to the invention comprises a timer circuit and means for detecting an abnormality. The timer circuit normally outputs a first signal after the generation of the film winding start signal and before the generation of the film winding end signal, and also outputs a second signal after the generation of the film winding end signal. If the film winding end signal is being generating at the time of output of the first signal or if the film winding end signal has not yet been produced at the time of output of the second signal, said abnormality detecting means delivers to the motor drive mechanism a signal for stopping the motor.
