Abstract
Abstract A main body (13) of a lens-fitted photographic film unit is provided with a film wind-up mechanism (9), a taking lens (5) and a shutter mechanism (12). The main body (13) with an unexposed film incorporated is covered by a front (15) cover and a rear (16) cover therebetween, which are attached to each other by arresting claws in holes formed thereon. The main body (13) is positioned by being held fixedly between the two covers in order to prevent the main body from being damaged when the two covers (15,16) are removed. In a preferred embodiment, the main body is provided with an electronic flash device (10), which is operated in synchronism with a shutter blade by use of an X contact. A pair of terminals of metal plates extend toward, and are in contact with, a printed-circuit board which is removably supported on the main body by cooperation of supporting members and a supporting plate, both of which are formed on an outside of a light-shielding tube of the main body.
