Cine projector with automatic cassette change - motor-driven means moving series of cine cassettes into projection position

摘要

The cassettes can by successively moved from a storage position to the projection position at which the cassette can be engaged and disengaged from the film web drive. The cassette changing means comprises a rotating plate (1) driven by an electric motor (2) with upstanding posts spaced around the periphery of the plate (1) for locating the cassettes, so that these are successively brought into the projection position as the plate is rotated. The cassette is electromagnetically ejected at the projection position operating in conjunction with spring means. The plate rotation stops at the precise position due to a positioning electromagnetic (EP) which abuts a stop (9) associated with a contact for cutting the motor circuit.
