Abstract

This annotator is used in an electrophotographic printing machine capable of of magnifying or reducing a copy of an original document. A movable occluder bar masks a marginal region of the charged portion of the photoconductive belt to insure that the enlarged or reduced image of the original document does not expose this marginal region. The occluder bar moves as a function of the lens used to project the light image of the original document onto the charged portion of the photoconductive belt. This insures that the masked region corresponds to the enlargement or reduction of the the original document. Thereafter, a projector including light emitting diodes which are selectively energized, selectively discharges the charged region masked by the occluder bar to record the desired marking information on the copy.
