Abstract

The projector gives an 18 x 13cm picture from a Super - 8 cassette, and is contained in a 34 x 32 x 16 cm box. It uses three mirrors to reflect the image coming from the lens round the box on its way to the viewing screen, the light path being folded so as to maximise the magnification obtainable in the comparatively small space. The light source is mains-operated lamp and condenser lens. A small mirror - which projects into the cassette and must swing aside when a new cassette is inserted - reflects the light through the film and on to the lens.
