Abstract:
PURPOSE: To execute the photographing action of prescribed sheets even when a shutter opening and closing action is inspected by loading a photographic film in a state where the film is drawn out by length being equal to or longer than one frame further after it is drawn out by length as much as the first frame is set at an exposure aperture.
CONSTITUTION: On the photographic film 26, two perforations are formed per one frame only at a film exposure part which can be utilized for photographing. The film is drawn out by the length being equal to or longer than one frame from draw-out that the first frame of the film 26 is set at the exposure aperture 33b, that means, by length just before a laboratory space 38c is set at the exposure aperture 33b. Then, a formed film roll 26a is loaded in a film roll chamber 27 and a cartridge 24 is loaded in a cartridge housing chamber 25. By fitting a back cover thereafter, the photographic film with a cartridge is light-tightly housed. Therefore, the inspection is executed by executing shutter charge by using a prescribed jig without winding up the film.
