PURPOSE: To decelerate the rotating speed of a motor to a specific level and to fix a stop position by allowing a motor control circuit for a camera to use the output of a pulse generating means fitted to the motor for power-on control.
CONSTITUTION: When a reset signal A is inputted at the end of photography, a film winding motor 1 is powered on with the high output of an NOR gate 16 and a pulse B is generated. When a counter output Q7 goes up to a high level C at a specific position (right before one frame of a film is fed) close to a stop position, an AND gate 13 which receives it turns on and off according to the output of a one-shot multivibrator 12 which receives an output waveform. Consequently, the pulse interval of the NOR gate 16 is short. Namely, as the rotating speed of the motor 1 goes to higher and higher, the duty ratio of electricity feeding goes to smaller and smaller, and deceleration becomes large, so the NOR gate 16 is closed with an output Q8 at the stop position and then the motor is stopped at the specific position.
