ABSTRACT:
The audio-visual apparatus comprises a single cassette which contains both the magnetic tape with the audio section recorded thereon and the photographic film with the video section consisting of a series of mono or stereo frames. The payoff spool and the takeup spool of the magnetic tape are coaxial respectively to the payoff spool and to the takeup spool of the photographic film, and there is provided a device for stopping the motion of the photographic film with respect to the motion of the magnetic tape, so as to allow the reproduction of the audio section during the projection of a photographic frame. The audio-visual apparatus comprises also a reproducing device which serves for the reproduction of both the audio and video section and which consists of a drive mechanism for driving into motion the spools of the magnetic tape so as to cause same to be explored by a reproduce head, and the spools of the photographic film so as to cause same to pass along a path on which there is arranged a source of illumination for the projection of the single frames. In the reproducing device there is also provided control element cooperable for actuating the above mentioned stopping device for the photographic film.
