Abstract

PURPOSE:To reduce the rotations of a motor by limiting a voltage applied to the motor when a temperature is below a prescribed value, by using the detection signal of a temperature detecting means provided in a camera. CONSTITUTION:A camera 10 is connected to a motor driving device 11, which includes a torque detection part 6, a motor drive controlling circuit 12, a motor braking circuit 14, a voltage limiter circuit 13 having a temperature detection part, etc. The torque detection part 6 detects the winding torque of a film increasing and then closes an SW4. Further, the rotations of the shaft of a motor M1 are transmitted to the winding mechanism of the camera 10 by a coupler 3 through a gear train, etc. At low temperature, the limiter circuit 13 is put in operation to prevent a voltage higher than a certain voltage from being applied to the motor 1 which is rotating.
