Abstract

The invention relates to a mechanical contact screen generator. The subject of the invention is a mechanical contact screen generator characterised in that it comprises a support framework 1, on which is mounted a film framework 2 of conventional type, and in which are placed the film 27 to be exposed and an appropriate screen 28, a light gun 5 directed vertically in the direction of the film framework, and mounted so as move in translation horizontally above the said framework 2, means 6, 7; 12, 13 for supporting and guiding the gun 5, means 6 to 9 for moving the gun along the said support and guiding means, and control means for automatically varying the degree of luminosity of the lamp 15 of the gun 5 as a function of the displacement of the latter. Application to producing mechanical contact screens.
