Abstract

Overhead projector additionally equipped with a splitter mirror, antireflection-coated on one side, next to the projection head or mounted exchangeably therewith. When looking into the auditorium, the speaker simultaneously sees the mirrored text on the rear of the paper, which lies with the script downwards on the illuminated surface. Texts written on paper can be read, and transparencies can be projected in turn when they are fed, glued to one another, by means of a motorised text follow-up device.
