  • Patent number: 3999848
    Abstract: A cartridge having a film handling portion and an audio tape cassette storing portion for use with an audio-visual system. The film storing portion includes a supply and take-up reel which are coupled by an intermediate gear so that the rotation of one reel is coupled to the other and means for transporting the film spooled about the reels past an aperture plate in either a continuous or intermittent motion mode. Provision is made in the cartridge for allowing the projection of light through the image portion of the film positioned at the aperture in the aperture plate and through an auxiliary frame in the film positioned at an auxilliary aperture to identify the number of the image portion being projected. A standard audio tape cassette containing the audio portion of the audio-visual presentation associated with the film may be stored in the tape cassette storing portion facing towards the opposite side of the cartridge from the aperture plate.
