An optical copying arrangement, particularly an electrostatic copying arrangement, has a carriage provided with a transparent supporting plate for an original and movable in a substantially horizontal direction, a drive for moving an image carrier onto which an image is to be copied from the original, and a scanning system arranged to scan the original supported on the supporting plate by successive strips and form a copy on the image carrier, wherein the supporting plate has a part which in initial position of the carriage is located prior to a first strip, considered in direction of carriage movement, and is bent downwardly relative to the main part of the supporting plate.

Optical copying arrangement

An electrostatic copying device comprises a transparent support plate onto which an original to be copied is placed. A slide carrying a recording cylinder provided on its peripheral surface with a photosensitive layer is movable beneath and parallel to the transparent support plate. At least one gear coaxially fixed to the recording cylinder meshes with a rack extending parallel to the path of movement of the slide to rotate the recording cylinder during movement of the slide. The slide carries also a raster objective stepwise scanning the original during movement of the slide to produce a latent image of the original on the photosensitive peripheral surface of the recording cylinder, which picture is transferred to an endless dielectric band forming an intermediate recording carrier and from the latter the picture is transferred to a photosensitive paper sheet fed onto the band along which also a plurality of usual treating stations are arranged for developing the image on the paper sheet.
