ABSTRACT:
An apparatus for displaying the status of a film cartridge in a camera, the cartridge having a film exposure status indicator for identifying whether the cassette is fully unexposed, partially exposed, or fully exposed. The apparatus includes a blocking member which cooperates with the status indicator of the cartridge to prevent the loading of a fully exposed film cartridge, and a multiple state switching element which cooperates with the blocking member to sense the state of a loaded cartridge. An LCD provides user feedback as to the state of the camera depending on the state of the switching element.
