Film loading apparatus using planet gear

摘要

A film loading apparatus for enabling a smooth initial film feeding operation by preventing a planet gear from being sent flying to a rewinding gear. The rewinding gear is connected to a fork gear which engages a take-up shaft of a patrone, and the feeding gear is connected to a one-tooth sprocket having a pawl tooth which engages a perforation of a film at the time of initial film feeding. A sun gear and the planet gear are connected to the pinion of the motor for taking up a film, and the planet gear moves between the position at which the planet gear meshes with the feeding gear and the position at which the planet gear meshes with the rewinding gear. A stopper member is provided at the position at which the stopper member checks the movement of the planet gear when the planet gear is disengaged from the feeding gear and sent flying reward the rewinding gear at the time of initial film feeding and at which the stopper member engages the planet gear when the planet gear is reversely rotated and moved toward the rewinding gear. This structure prevents the planet gear from being sent flying and meshing with the planet gear at the time of initial film feeding.
