ABSTRACT:
An optical copier has a transparent support on which an imaging area is bounded by a frame having at least one abutment edge for an original to be copied which is placed on the support. To guard against a possibly remaining gap between original and abutment edge being reproduced in the copy as a dark area, the underside of the support facing away from the original is provided with a transparent or semi-transparent strip extending along the abutment edge and projecting beyond the same into the imaging area by about 1-5 mm. A surface of the strip facing towards an optical imaging system is light-scattering.
