Abstract

See full text

A film feeding apparatus in a camera comprises a feeding device for feeding film from a film cartridge, a take-up spool device for taking up the film fed by the feeding device, and a judgment device for judging on the basis of a variation in the movement speed of the film whether the film has been taken up by the take-up spool. The movement speed of the film is determined by the feeding device before the film extending from the film cartridge is taken up by the take-up spool device, and the movement speed of the film is determined by the take-up spool device after the film has been taken up by the take-up spool device. The movement speed of the film driven by the feeding device differs from the movement speed of the film driven by the take-up spool device.
