Abstract
An overhead projector for projecting images contained on media. The projector includes a housing having first and second image media storage cassettes and a platen which moves between those cassettes. A lifter is mounted between the cassettes for lifting the media from the first or second cassette onto the platen for projection. The lifter includes a lifting drive and a media gripping device. An image projector is movably mounted to the housing and positionable over the first or second cassette to project an image from media positioned on the platen to a view area. The projector includes a movable arm containing an illumination source, mirror and lens. Image media contained in a cassette can be sequenced from that cassette to the other by lifting onto the platen, from the cassette, projected and deposited in the other cassette either manually, remotely, automatically, or semiautomatically.
