Abstract
A camera is disclosed which is capable of winding and rewinding a film and adjusting a focal distance by use of a single motor. In the camera, the forward rotation of the motor is used to wind the film, and when the film winding operation is completed after termination of photographing, on detecting the end of the film, a torque detect mechanism switches a planetary clutch mechanism to connect the motor with a film rewinding mechanism. Thus, it is possible to perform both the film winding and rewinding operations by use of the rotation of the motor in the same direction. Also, when, with the planetary clutch mechanism connected with the film winding mechanism, the motor is rotated reversely, then the power transmission system is switched over to a focal distance varying mechanism, whereby the focal distance can be adjusted.
