Claims

[Scope of utility model registration request]

During winding, the drive source is connected to the sprocket and spool using a clutch mechanism, and during rewinding, the clutch is disconnected and separated from the drive source.In the film feeding mechanism, the force for engaging the clutch is applied to the drive system during winding. A camera film feeding mechanism characterized by being sealed in a part that does not rotate during rewinding.
