1. Field of the Invention
The present invention relates to a film projection system and more particularly to a film projection system wherein in response to the actuation of a selector system, a cartridge containing a film program is automatically transferred from a storage magazine to a film reproduction unit in which the film program is reproduced, the cartridge being returned to the storage magazine upon completion of the film program.
2. The Prior Art
There are many types of film projector systems in the prior art. In one such system, a storage reel containing a film program must be manually placed on the projector and the film manually positioned or threaded through the projector to permit reproduction of the program retained on the film. More recently, projector systems have been developed in which, after the storage reel is placed in the projector, an end of the film is inserted into an automatic threading device and the projector will be threaded automatically. In all of these prior art projection systems the storage reel containing the film has to be positioned on the projector by hand. In addition, the film must either be threaded through the projector by hand or one end of the film must be inserted by hand into an automatic threading device in the projector. In either case, the presence of an individual to assist in the operation of the projector is required which severely limits the use of the projection system, especially in the field of entertainment.
Sound systems have been developed such as the wellknown record player or "Jukebox" which permit individuals to select a sound recording from a collection of recordings, and the sound recording then played automatically. While such sound systems have enjoyed tremendous popularity, no such system has been developed applying similar principles to reproduce film programs in which the individual would not only hear the sound recording but would also see a visual presentation of the artist performing. Such a system would open vast areas to pre-programed film performances which have heretofore been out of reach because of the inability to select and play automatically, a pre-recorded film. Presently, individuals viewing film programs in association with sound recordings must rely on the person in control of or who operates the projection system to select or choose the film to be reproduced.
It is toward the elimination of these and other problems that the present invention is directed.
