ABSTRACT:
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.
