Abstract
Abstract A lens-fitted photographic film package with a flash unit, wherein a main capacitor of the flash unit is disposed above a film roll chamber and lies parallel to the film transporting direction. A battery is disposed between the film roll chamber and a cassette chamber, below the taking lens, and also lies parallel to the film transporting direction. The battery is entirely masked when the film package has been assembled. A printed circuit board of the flash unit is substantially rectangular and has a cut-out at the upper right corner thereof in which is mounted a light projector of the flash unit.
