Abstract: A multipurpose film handling cassette of the type in which a photographic film strip is exposed, processed and projected without removal of the film from the cassette is provided with a two-piece "balanced force" arrangement for signaling to the apparatus with which it is to be used the unprocessed or processed condition of the film within the cassette. By "balanced force" it is meant that the indicating elements do not rely on any inherent deformation or internal resiliency to move the elements from an unprocessed mode to the processed mode. Further, no external force is required to act upon the terminals to hold them in a desired position.

Abstract: A photographic film cassette having a bowed spring yieldably biasing a pressure pad for supporting a film strip so that the latter is held in sliding engagement with a fluid processor nozzle. Spring support members formed on the cassette housing wall support opposing ends of the bowed spring so as to longitudinally position it, as well as engage other spring portions during spring deflection to prevent overstressing of the spring. The invention embodies a method of preventing overstressing of the deflected bowed spring while facilitating an increase in the spring force after a preselected deflection thereof.
