ABSTRACT:
A family of different type cameras is intended for use with a film cassette which is capable of being operated to thrust a filmstrip out of the cassette housing, regardless of whether the filmstrip is unexposed or is partially exposed, and which has film exposure-status indicating means for providing visible indications that the filmstrip inside the cassette housing is unexposed or is partially exposed. One type camera intended to be used only with a film cassette containing an unexposed filmstrip includes single indication means for providing a visible indication similar only to the one the film cassette provides that the filmstrip inside the cassette housing is unexposed, to advise that the camera can be used only with a film cassette containing an unexposed filmstrip. Another type camera intended to be used with a film cassette containing an unexposed or partially exposed filmstrip includes respective indication means for providing visible indications similar to the ones the film cassette provides that the filmstrip inside the cassette housing is unexposed or is partially exposed, to advise that the camera can be used with a film cassette containing an unexposed or partially exposed filmstrip.
