Abstract
A lens-fitted photographic film package with a flash unit and a viewfinder optical system, which is thin and contributes to effective and economical automatic recycling operations. The taking lens system of the film package is accommodated in a lens holder incorporated in a photo-taking unit having photo-taking mechanisms, and is held immovably in the lens holder by a lens cover removably fitted on the lens holder by snap-in engagement. The viewfinder optical system is also incorporated in the photo-taking unit. The photo-taking unit is removably attached to a main body of the film package, and the flash unit is removably attached to the main body with its printed circuit board disposed between the photo-taking unit and a front surface of a film supply chamber. A light emitting portion of the flash unit is secured to a lateral side of the printed circuit board, so as to be disposed above the film supply chamber. A metal blade constituting a flash charging switch is removably attached to the outside of the film supply chamber. A front cover is removably attached to the main body so as to cover the front and top of the main body, the photo-taking unit and the flash unit.
