Method of manufacturing a lens-fitted photo film unit as well as the lens-fitted photo film unit and photographic film

摘要

PROBLEM TO BE SOLVED: To photograph according to the prescribed number of sheets in a previously decided photographing area in photographing sequentially from a frame on the trailing edge side of a film. SOLUTION: A pair of perforations 16 and 14 for controlling the feeding of the frames arranged at a short interval L1 from the leading edge 13b side of the film is arrayed at an interval L2 on the photographic film 13. Besides, the film 13 is provided with one perforation 14b according to the trailing edge of the final frame 15b. When the film 13 is used by a film unit with a lens photographing sequentially from the trailing edge 13a of the film 10, it is provided with one perforation 17 in the interval L1 toward the more trailing edge 13a side of the film than the perforation 14b so that the final frame 15b can be positioned by detecting that a pair of first perforations 16 and 14a is moved to a prescribed position being nearer to a cartridge side than a photographing optical axis. Then, a pair of perforations for controlling the feeding of the frame is constituted of the perforations 17 and 14b besides.
