ABSTRACT:
A method of loading film into a camera that employs a film cassette with a light lock door and has a back cover securely affixed to a main body includes loading the film cassette into a film cassette compartment via a film loading port with the light lock door closed, operating an advancing means to engage a light lock door driver affixed to the camera, rotating the advancing means to open the light lock door with the light lock door driver, preventing further rotation of the advancing means from operating the light lock door driver; continuing to rotate the advancing means to drive film out of the cassette across the film path and into a film receiving slot contained in a film spool and winding film from the cassette onto the spool. Additionally, a camera includes a mechanism for opening and closing a light lock door of a film safe cassette and the mechanism for opening and closing the light lock door. The method described above may also include loading film and/or operating the light lock door of the film safe cassette while at least a potion of the film path is exposed to light.
