A camera is provided with a power-driven film winding device in which a high-voltage circuit is completed upon depression of an operating button so as to supply high voltage to a motor to wind a film at high speed for phototaking; and upon releasing of the operating button, the high-voltage circuit is changed over to a low-voltage circuit so as to wind the film with the aid of low voltage after the phototaking and ensure that the motor stops at a predetermined position where subsequent film winding and shutter charging is completed.
