The cassette contains processing means, operating in a predetermined sequence determined by means within the cassette, and energized by drive energy supplied externally to sprocket holes on the film and to the takeup and supply reels by the film drive and projection system. An electrical signal generator within the cassette supplies an external signal to select the mode of operation of the film drive and projection system in dependence upon the processed or unprocessed state of the film.
