<p>An apparatus for exposing and developing a sheet of light-sensitive material, said apparatus comprising an optical image-producing system consisting of an original plane (10), an objective plane (8), and an image plane (6), and a developing station (18, 20), whereby the sheet of light-sensitive material can be advanced after the exposure in the image plane (6) to the developing station (18, 20) so as to be developed. The apparatus comprises further an image-setter (22, 22') placed adjacent, preferably below the image plane of the optical image-producing system, and guiding means (24) for advancing the material exposed by the image-setter to the developing station (18, 20). The image-setter can be placed in the usually unutilized cavity below the optical system. In addition, the apparatus allows several possibilities of use. It turned out that the same developing station can be used. The image-setter can optionally be adapted to expose selected portions of the light-sensitive material, which can subsequently be exposed by means of the optical image-producing system. In this manner some portions of a sheet of light-sensitive material are exposed by means of the image-setter, whereas other portions of said material can be exposed by means of the optical image-producing system. As a result, the apparatus is more universal than previously known. <IMAGE></p> |
