Abstract
Abstract A motorized camera having a gear train between an electric reversible motor and a film rewind fork with a mechanism for transferring the driving torque from an intermediate gear of the train to move a member having function other than film transportation as the gear is out of mesh with the next one, wherein a mechanism is provided between the last gear of the train and the rewind fork so that only when the last gear has rotated by a prescribed angular distance, the fork starts to engage the supply spool of the film cartridge to rewind the film.
