Abstract

The equipment allows successive exposure of parallel zones on a photo-sensitive surface. The surface is situated on a double drawer (1) sliding in a sleeve (2) impervious to light. It can be brought opposite a window (6), which can be masked by a hinging shutter (5). Movement of the drawer enables several zones to be brought opposite the window in succession. The sheath can be formed by a prismatic profiled section.
