Abstract

1376814 Electro-photographic apparatus; optical systems XEROX CORP 18 Jan 1972 [21 Jan 1971] 2290/72 Headings G2A and G2H Enlarged xerographic copies are obtained from the frames of a microfilm 105 or other record medium by means of an enlarger which incorporates a beam-splitter 112 and viewing screen 113, so that the frame being enlarged can be monitored before travelling slit shutter 116 is actuated to expose a photo-conductive member 114. The beam-splitter 112 may incorporate interference filters, so that the projected image from lens 104 is split into images of different colours, or the visible part of the spectrum is reflected and ultraviolet or infrared is transmitted to expose the member 114. A charging corona discharge device 115 may be incorporated in the same moving assembly as the shutter 116, and filters may be inserted in the shutter to improve image contrast. After exposure, the member 114 passes to developing means 120, where the polarity of its latent image may be changed to yield a positive electro-photographic print.
