ABSTRACT:
A recyclable, single use photographic film package and camera comprising a light/tight film casing having an exposure opening, a roll of unexposed film withdrawn from its canister and wound on a film winding reel disposed on one side of the exposure opening in the light-tight casing, the canister disposed on the other side of the exposure opening in the light-tight film casing, and an externally operable film winding thumbwheel for winding the film past the shutter and image area and into its canister as the film is exposed frame by frame. When all frames are exposed, the package is recycled after processing the exposed film by substituting a fresh roll of film and new packaging for resale. To prevent unauthorized reuse of the camera by refilling it with other than genuine film, a component of the film frame counter is intentionally damaged upon winding the last frame into the film canister which renders the exposure counter unusable until the component is replaced by an authorized recycler of the film package.
