Abstract

The slide projection system has a projector (3) designed to form on a screen (4) a enlarged seal image of a slide. The system consists of a housing (1) having a horizontally sliding drawer (2) in which is fixed the projector (3). The housing (1) has a front vertical face (4), the drawer (2) being below this front face which is formed of a translucent plate which constitutes the systems screen. Inside the housing is an optical system (9, 10) which is designed to reflect the image transmitted by the projector (3) onto the screen (4) with clearness and correct centring when the drawer is in a predetermined extreme withdrawn position.
