ABSTRACT:
An apparatus for stripwise viewing a document and for projecting an image thereof onto a moving imaging surface. The viewing apparatus includes at least one reflector having a reflecting surface and being arranged along an optical path. An illumination slit controls the projected illumination intensity. The slit is defined by at least one boundary configured in a desired profile. The reflecting surface of the reflector is delimited so that at least one boundary defined by the reflecting surface is configured in the desired slit profile, whereby the reflector and slit are arranged integrally together. A reproducing apparatus and a process for making the viewing apparatus also are claimed.
