Abstract
A film drive mechanism for a camera, in which a drive force of a motor is transmitted through a differential gear mechanism to a wind shaft and a rewind shaft and is also transmitted through a screw gear to a spool shaft or a fork shaft whereby, operations of winding and rewinding film are performed. The rewind shaft is placed in such a manner as to be inclined to the drive shaft of the differential gear mechanism. Also, a pair of engaging gears in the drive force transmission device are aligned so that their axes of rotation are oblique to one another. This film drive mechanism requires small space than conventional designs and is small in weight and is advantageous for the cost thereof.
