Zusammenfassung:	A motor driving device for a camera is provided in which the motor is placed in an energizing circuit which includes a governor. A switch is provided in parallel with the governor and is adapted to be operated by a relay. When the switch is opened, the governor can effectively control the speed of the motor in order to prevent overrunning of the film during the winding operation. When the switch is closed, the governor is short-circuited and the motor can run to wind the film or control exposure.
