Cassette rotary tray slide projector and slide cassette usable therewith

A slide projector and a slide cassette usable therewith for projecting slides. The slide projector includes a casing having a central hub located therein. Mechanisms for illuminating and projecting slides are located within the central hub. Also located in the central hub is a slide passage oriented generally vertically. A slide receiving tray in the casing is movable with respect to the central hub and includes a plurality of radially oriented compartments for receiving projected slides. The slide cassette containing slides to be projected has a slide storage tray rotatable with respect to a housing. The housing is releasably held in a predetermined position in the casing. The slide receiving tray is rotated by a motor so that the compartments of the slide storage tray and slide receiving tray are sequentially aligned with the inlet and outlet of the slide passage so that slides to be projected fall under the force of gravity out of the uppermost compartment, through the slide passage, and into a lowermost compartment.
