Abstract
A lens-fitted photo film unit containing photo film having a pair of perforations per frame along through a limited length of frame recording portion available for photographing frames. The photo film is previously drawn from a cassette shell, its trailing end secured to a spool of the cassette shell, so as to be wound into the cassette shell one frame after each exposure. According to the invention, the photo film is drawn from the cassette shell as far as a frame of the frame recording portion that is the nearest to the trailing end, and is set in a position one frame or more farther than an exposure position of the film unit, when loading the photo film in the film unit. A slot is formed through the film unit, for permitting insertion of a tool to set a shutter device to its charged position, without the need for winding the photo film. Alternatively, the shutter device is designed to be charged by use of rotation of a film winding wheel, independently of the perforations.
