Abstract: A device to translationally pass a document having multiple sheets on a copier comprises an adapter element for placement on the portion of the copier housing the picture taking assembly, the adapter comprising a longitudinal plate and a transverse portion extending transversely from the longitudinal plate. The transverse portion has a longitudinal cross-section of substantially triangular outline for forming a planar surface with the portion of the copier housing the picture taking assembly. A longitudinal slide bar is positioned above and extends the length of the longitudinal plate and the transverse portion. A transparent plate bears the document to be carried and includes on one edge thereof means for slideably engaging the slide bar, whereby the bottom of the transparent plate can engage the lower drive apparatus of the copier and be driven thereby over the picture-taking assembly.

Abstract: Assembly for taking pictures in copiers comprising illuminating tubes, an optics and devices for driving in translational movement the original document in sheets for taking picture, line by line, wherein a light-proof housing disposed in the body of the copier comprises in the center, an assembly of optical fibres disposed along the length of the line, and on each side, an illuminating tubular assembly and a driving roller.
