Abstract
An electrophotographic printing machine in which a transparency or an opaque original document is reproduced. In reproducing a transparency, a mirror is pivoted from a position remote from the light image path into the path of the transparency light image. When an opaque original document is being reproduced, the mirror is pivoted to the position remote from the light image path.
Claims13
An electrophotographic printing machine for reproducing a transparency or an opaque original document, including:
- a receiving member;
- a photoconductive member;
- means for charging at least a portion of said photoconductive member to a substantially uniform level;
- means for projecting a light image of the transparency;
- means for modulating the light image of the transparency;
- and
- means for directing the light image of the transparency through said receiving member and said modulating means onto the charged portion of said photoconductive member selectively dissipating the charge thereon to record an electrostatic latent image thereof, said directing means being movable from a first position remote from the path of the transparency light image wherein the electrophotographic printing machine reproduces the opaque original document to a second position in the path of the transparency light image wherein the electrophotographic printing machine reproduces the transparency.
