ABSTRACT:
The copier has a transparent support upon which originals to be copied are laid with their image-bearing sides face down. The image-bearing sides are illuminated and reproductions are made of the illuminated images. An arrangement for use in the reproduction of printed forms, form letters, and the like, includes first and second holding devices located adjacent the transparent support. The first holding device holds two lower originals which serve as masks and are spaced apart to form an intermediate slit. The second holding device holds an upper original located above the lower originals with a portion of the upper original showing through the slit and being unblocked for illumination. At least one holding device is mounted movable relative to the other in the direction of the length of the transparent support. By effecting such relative movement, different lines or portions of an image on the upper original can be unblocked by the mask for illumination and reproduction.
