-0- CAMERA FOR USE WITH FILM CASSETTE HAVING FILM-EXPOSURE STATUS INDICATOR ABSTRACT OF THE DISCLOSURE A photographic camera is intended for use with a film cassette having a film-exposure status indicator movable from an unexposed position for providing a visible indication that a filmstrip within the cassette is generally unexposed, to a partly exposed position for providing a visible indication that the filmstrip is only partly exposed, and to an exposed position for providing a visible indication that exposure of the filmstrip is complete. The camera is capable of returning the filmstrip to the cassette prematurely when the filmstrip is only partly exposed and of advancing the filmstrip from the cassette subsequently to complete its exposure, and includes control means that operates drive means to move the status indicator from its unexposed position to its partly exposed position in the event the filmstrip returned to the cassette is partly exposed and to move the status indicator from either its unexposed or partly exposed position to its exposed position in the event the filmstrip returned to the cassette is substantially exposed.

Appareil photographique destiné à utilisation avec une cassette de pellicule comportant un indicateur d'état d'exposition pouvant passer d'une position de non exposition pour indiquer visiblement que la pellicule à l'intérieur de la cassette est essentiellement non exposée, à une position d'exposition partielle pour indiquer visiblement que la pellicule à l'intérieur de la cassette est partiellement exposée, à une troisième une position indiquant que la pellicule a été complètement exposée. L'appareil est capable de rembobiner la bande de film à l'intérieur de la cassette après exposition partielle et de la faire avancer par la suite pour une autre exposition. L'appareil comporte un dispositif pour commander le mécanisme d'entraînement de l'indicateur d'état de la position de non exposition à la position d'exposition partielle dans le cas où la bande de film rembobinée ne serait que partiellement exposée, et pour ramener l'indicateur d'état de la position de non exposition ou d'exposition partielle à la position d'exposition complète dans le cas où la bande de film rembobinée serait essentiellement exposée.
