Abstract

PURPOSE: To surely load photographic film without causing the fogging of the photographic film by production in a darkroom by using a film cartridge having a cover for shielding light. CONSTITUTION: In a darkroom, the cover for shielding light of the cartridge main body 2 of the film cartridge 1 is opened so as to open a film paying-out path, and the photographic film F housed in the cartridge main body 2 is paid out from the film paying-out path by the rotation of a winding spool 3 in a paying out direction. Then, the leading edge F1 of the film F is engaged with a take-up spool 9 and further the film cartridge 1 in which the leading edge F1 of the film F is engaged with the take-up spool 9 is loaded in the film integrated type camera. By rotating the take-up spool 9 in this loaded state, the film F is taken up.
