ABSTRACT:
A copying apparatus with a document copying platen, including a substantially uniformly light reflective platen cover for holding documents against the platen, and including document drive wheels having light reflective constant width surfaces partially extendable through fixed apertures in the platen cover towards the platen. The fixed apertures in the platen cover are wider than the drive wheels to allow their limited transverse movement. Light reflective shields having an aperture the same width as the wheels are mounted in the platen cover so that each wheel extends through a light shield aperture with each light shield closely fitted to both sides of a wheel. Each light shield is movable transversely together with its wheel, but each light shield constantly overlies its fixed aperture in the platen cover irrespective of this transverse movement to constantly present a substantially uninterrupted light reflective surface over the platen together with the wheel.
