ABSTRACT:
A film feeding apparatus for a camera to feed a film from a cartridge is so structured that preparatory wind-up starts not immediately after a close signal indicating that a rear cover is closed is generated, but after a predetermined delay time elapses from generation of the close signal, i.e., after the rear cover is completely closed. The film feeding apparatus will not undesirably expose a film even if a rear cover detection switch is operated before a rear cover is completely closed.
