ABSTRACT:
A film feeding apparatus includes a roller pair for pinching a film stored and wound within a film container or its leader, and a restricting passage for restricting a posture of a non-pinched portion of the film or its leader. The roller pair is disposed in such a manner that the film or its leader is entrained about one roller of the roller pair in an arcuate form toward an upstream side in a film feeding direction relative to a pinching position of the roller pair. With driving rotation of the roller pair pinching the film or its leader, the film is withdrawn from the film container held at a holding portion to be fed to a film processing section. The restricting passage is curved along an entraining passage of the roller for the film or its leader as the restricting passage is viewed in a direction of an axis of the roller.
