ABSTRACT:
A camera of a preliminary winding type in which a film in a patrone is previously taken out from the patrone to roll it round a spool and, each time one frame photographing is completed, the film is rewound into the patrone by one frame in photographing. The camera comprises a motor, a preliminary winding mechanism, a frame-by-frame rewinding mechanism, a focal length varying mechanism, first and second planetary clutch mechanisms, and an engagement mechanism for locking the first planetary clutch mechanism, and is capable of switching the power transmission to the preliminary winding, frame-by-frame rewinding and focal length varying mechanisms by changing the direction of rotation of the motor.
