  • Patent number: 5682566
    Abstract: A contact position at which the photographic film sent out from a film cartridge first contacts a film guide means is determined in such a manner that the photographic film does not contact a film entrance of the film cartridge when a film winding diameter in the film cartridge is at its maximum, and that only the edges of the photographic film, which curls in a direction of its breadth, which is not an image area, contacts the film entrance when the film winding diameter is at its minimum. As a result, the image area on the film is not damaged if the film is transported back and forth many times, and dust which causes damage to the film can be reduced.

  • Patent number: 5646747
    Abstract: At the center of a guide plate, another guide plate is provided. A convex curved portion is formed on the guide plate, and a concave curved portion is formed on the guide plate facing the curved portion. The force for straightening a photographic film acts on the curled photographic film when it passes between the curved portions. As a result, the photographic film curled in the cross direction is straightened in a predetermined range. A line sensor reads out an image of a straightening position where photographic film curled in the cross direction has been straightened by the curved portions. As a result, even when the photographic film is fed in such a state that it curls in the cross direction, the straightening position keeps straightened by the function of the curved portions, so that a satisfactory image can be displayed on a monitor TV.
