Abstract: A film projection system includes a collection of cartridges each containing a film program. The cartridges are stored in a storage magazine. A selector system permits a particular film program, which may be identified by a code, to be chosen and displaces the storage magazine so that the cartridge containing the selected film program is positioned at a transfer point in which it is adjacent a transfer mechanism. A transfer mechanism is adapted to remove the cartridge from the storage magazine and position the cartridge in a film reproduction unit. Upon positioning of the cartridge within the film reproduction unit, the film will be displaced within the cartridge and will be reproduced by the unit. Upon completion of the film program, the transfer mechanism removes the cartridge from the film reproduction unit and returns the cartridge to the storage magazine.
