<p>An electrophotographic printing machine in which the platen thereof is a field lens. In the opaque reproduction mode, the original document is positioned on the platen in a light receiving relationship with the illumination system. The presence of the field lens does not interfere with the opaque copying mode of the printing machine. When a transparency is being reproduced, the light image of the transparency is projected through the platen. The field lens converges the diverging light rays of the transparency light image. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to be limiting as to the scope of the invention in any way.</p> |
