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 one-piece indicating element for signaling to the apparatus with which it is to be used the unprocessed or processed condition of the film within the cassette. A contact element is mounted within the cassette for rotation about a fixed axis from a first position wherein it will operatively engage a signal generating terminal of the apparatus thereby indicating a given process condition of the film within the cassette, to a second position wherein it will not operatively engage the signal generating terminal of the other apparatus thereby indicating a different process condition of the film in the cassette.
