<p>In apparatus for a continuous contact exposure of photosensitive materials by progressive scanning by means of a slot source of light an original film (1) and a photosensitive sheet (2) are brought into direct contact with each other and then exposed to the radiation from a light source (4) disposed beyond a transparent flat supporting surface (3). The film (1) and sheet (2) are advanced by driving rollers 5, and the light radiation is covered by screening means (6) provided with at least one slot (7) suitable to form a slot of light transverse to the feed direction of the film (1) and sheet (2) and lying in a plane substantially perpendicular to the latter. <IMAGE></p> |
