Abstract
Abstract A compartment defining a cassette receiving chamber in a photographic camera is movable outwardly from the camera body to insert the type of 35 mm film cassette that contains a non-protruding film leader into the chamber. A loading opening to the chamber has a continuous enclosed perimeter commensurate in shape with an outline of the aforementioned film cassette. This feature prevents the type of film cassette that has a protruding film leader from being inserted into the chamber, by obstructing the protruding film leader.
