ABSTRACT:
A film feeding apparatus of a camera moves a film when the camera is switched to its nonoperative state or has not been operated for a predetermined time, in order that focusing is not affected by film deformation caused by a pair of flanges of the film cartridge when the film has been left for a long time. A film feeding motor feeds the film, and a perforation detector or a film encoder outputs a signal corresponding to the feeding amount of the film. When the camera is switched to its nonoperative state or has not been operated for the predetermined time, a CPU in response to the film feeding amount signal causes the film to be moved by a predetermined amount in a first direction. Further, when the camera is switched to its operative state or an operation command is inputted, the CPU causes the film to be moved in a second direction opposite to the first direction. Thus, when the film has not been exposed for a long time, a frame of the film to be next exposed is moved to a position which is not susceptible to film deformation.
