摘要:
A photographic camera is provided with a magazine receiving chamber formed in the camera body and shaped to permit insertion of a film magazine having a film leader into the chamber only in one axial direction of the magazine, and inner and outer guide member for guiding the film leader in between the film aperture and a film pressure plate as the magazine is inserted into the chamber. The film pressure plate is resiliently mounted on the camera body to be movable toward and away from the film aperture. A pressure plate pushing member is mounted on the back lid of the camera body to push the pressure plate toward the film aperture when the back lid is closed. When the back lid is opened, the pressure plate returns to its rest position in which its inner surface is flush with the inner surface of the outer guide member and provides a planar guiding surface. Engaging pins of film feeding means are retracted inwardly from the outer surface of the inner guide member so as not to snag the longitudinal edge of the film leader when it is guided in between the pressure plate and the film aperture. When the film leader is pushed toward the film aperture by the pressure plate upon closure of the back lid, the engaging pins brought into engagement with the perforations of the film leader. The upper edge of the inner guide member is chamfered so that the film leader can be smoothly stretched therealong as the magazine is inserted into the chamber.
