PURPOSE:To eliminate the danger of pulling out a film by mistake at the time of handling by providing means of loading a film cartridge in a camera and advancing the film to the outside of a case after loading. CONSTITUTION:The film 2 is wound along a spool 3 and the front end thereof arrives downward by emerging from an aperture 4a in the state before loading in the camera 11. A light shielding wall 6 is energized downward by a coil spring 8 and is shifted rightward by a leaf spring 7. The film 2 wound along the spool 3 before the spool is rotated expands gradually toward the outside and is wound along the inner side of an inside ring 4 when the spool 3 is rotated counterclockwise by a camera side film drawing mechanism. Since the inner side 4 begins to rotate together with the film, a projecting part 4b lifts the light shielding wall 6 upward by overcoming the energizing force of the coil spring 8 and an outlet 5a is opened. The drawing out of the film by mistake at the time of handling is obviated in this way and the danger of the entrance of the light to the inside is eliminated by the light shielding wall in the film outlet. |
