Abstract

An apparatus capable of using a film cartridge in a manner that a lead portion of a film contained in the cartridge is fed out therefrom by the film thrusting, wherein a controller judges that an initial loading is not executed normally when a perforation is not detected although a fed film amount on an initial loading reaches a first predetermined amount, and stops a detector from detecting a perforation until the fed film amount reaches a second predetermined amount which is less than the first. Thus, a detector does not wrongly detect a notch on a film's lead portion as a perforation, and a leading frame is fed normally with a reliable judgment on an initial loading.
