ABSTRACT:
A photographic camera includes a cassette chamber for containing a film cassette having a fork provided therein which is coupled to a spool in order to rotate the spool. After loading the film cassette in the cassette chamber, the fork is rotated by a motor in the winding direction for tightening a roll of the photographic film in order to prevent a film from jamming when advancing the film leader. The fork is then rotated in a normal or forward direction for advancing the film leader. In a preferred embodiment, a photosensor detects the photographic film fed from the film cassette and generates a detection signal. The fork is rotated in the normal direction before the reverse rotation. It is then determined whether the photographic film is advanced. If not, the fork is rotated in the reverse direction.
