Abstract An audio-visual system including a cartridge and an audio-visual housing. The cartridge contains an endless tape on one reel and an endless filmstrip in a loop. Means are also provided on the cartridge to bring the continuous tape and continuous filmstrip into communication with openings to the exterior of the cartridge. The audio-visual housing is adapted to receive the cartridge and start means on the housing are provided responsive to reception of a portion of the cartridge within the housing to activate a tape drive motor, a lamp and a power source. Tape engaging and audio pick-up means are in the housing to engage the exposed portion of the tape when the cartridge is received in the housing and is responsive to the tape drive motor to drive the continuous tape. Audio means are in the housing in communication with the pick-up head means to transmit the sound tracks from the tape. Discriminator means are positioned in the housing in communication with the pick-up head to receive and respond to a signal received from the tape. Film transport means are also in the housing to engage the exposed portion of the filmstrip when the cartridge is received in the housing and is adapted to transport the film. Film advance means is positioned in the housing and is in communication with the discriminator means and the film transport means so that when a signal is received by the discriminator means it will respond by causing the film advance means to drive the film transport means and transport the film to thereby permit the tape and film to be advanced in a predetermined sequence. A projector lens is located in the housing and is aligned with the exposed portion of the film and the cartridge positioned in the housing. Condenser and director means are in the housing and the cartridge positioned in the housing and is in association with the lamp to condense and direct light from the lamp onto the rear of the film and to pass through the film and aligned lens and thereby project an image of the exposed frame of film. Finally, cooling means is positioned in the housing to assist in preventing excessive heating of the exposed filmstrip and the interior of the housing.
A cartridge adapted for connection to an audio-visual projector comprising: an outer casing containing therein an endless tape having a sound track and a signal track on a first reel and an endless filmstrip in a loop; means on said cartridge to bring said continuous tape and continuous filmstrip into communication with openings in the casing of said cartridge; said tape and said filmstrip in said cartridge being in side-byside relationship with a separating wall therebetween; a tape turning member extending inwardly from the side wall of the tape portion of the cartridge and engaging said tape to twist at approximately 90* and facilitate the feeding of and rewinding of the continuous roll of tape; a film turning member extending inwardly from the side wall of the film compartment of the cartridge and positioned so as to engage and turn said film approximately 90* as it is unwound from said reel so as to facilitate the continuous feeding of the filmstrip; and a recess in the separator wall between the filmstrip compartment and the tape compartment of said cartridge located adjacent to said film turning member to facilitate the freedom of movement of said film as it is turned 90* in its continuous movement.
