Abstract
A lens-fitted photographic film package comprises a light-tight film case having exposure structure, a rolled film in a film roll receiving chamber disposed on one side of an exposure frame in the light-tight case, and a removable film container having a film winding spool therein disposed on the other side of the exposure frame in the light-tight film case. A member is provided for causing the film to be advanced smoothly without getting scratched, for preventing the film roll from becoming loose, and for preventing the film from being gouged by a film exit slot of the film roll receiving chamber.
