Abstract: A projector which simplifies the handling of 2 by 2-in slides for news and spot commercials in TV broadcasting has been designed to operate with linear magazines containing 40 slides or with a circular magazine having 120 slide compartments. A vertically oriented dual-channel optical system is provided; the light from the upper and lower channels is alternately directed into a single projection lens by means of an optical multiplexing arrangement. An auxiliary path in the optical system produces a preview image of the next slide to be projected on a translucent screen at the projector. Flexibility of programing and reliability of operation were the key considerations in the design of the solid-state circuits which control the operation of the slide projector.
