Abstract

A lens-fitted photographic film package has a sprocket which is disposed below an exposure frame of the film package. Film advance mechanisms, including a film winding wheel and a film stop device for stopping advance of the film each time the film has been advanced by one frame, and a frame number count device, may be respectively disposed in the upper or lower portion of the film package so as to cooperate with the sprocket. In a film package with flash unit, all these mechanisms are disposed in the lower portion of the film package, and a printed circuit board as well as a light emitting portion of the flash unit are disposed in the upper portion. The printed circuit board is placed horizontally above the film roll chamber and the exposure chamber, while electric elements mounted thereon are disposed on both horizontal sides of a viewfinder of the film package which is disposed above the exposure chamber.
