ABSTRACT:
A lens-fitted photographic film unit is constituted of a film containing unit, a photo-taking unit, and a front cover. The film containing unit is formed from plastic and has an exposure aperture, a film supplying chamber and a film take-up chamber. A shutter mechanism and a wind-up stopping mechanism have metallic parts and are assembled together into the photo-taking unit, so as to facilitate classification of plastic units and metal-containing units at the time of recycling. The photo-taking unit is removably secured to the front of the plastic film containing unit. In a preferred embodiment, a flash device is removably mounted on the film containing unit.
