Abstract

A lens-fitted photographic film package has at least an unexposed rolled film, a taking lens, a film transportiong mechanism, an exposure mechanism and an electronic flash as a whole contained in a light-tight case. The light-tight case comprises a main case section formed with a chamber containing therein light-tightly the unexposed rolled film and a front cover section attached to the main case section, the front cover section being formed with at least one opening for partially receiving therein a member of at least one of the mechanisms mounted on the main case section projecting beyond a plane defined by surfaces of the main case section in contact with an inner surface of the front cover section when the front cover section is securely attached to the main case section. The electronic flash unit is short-circuited to maintain the condenser of the flash unit discharged until the rolled film has been loaded in the light-tight case, so as to prevent accidental flashing that would expose the film. The lens-fitted photographic film package is enclosed in an external container having a weakened openable portion capable of being broken away from the external container to expose the contained rolled film for removal after exposure.
