Abstract
A triple function image processing system incorporating, for operation in a first COPY mode, a light/lens imaging system for imaging originals at a viewing station or platen to produce latent electrostatic images thereof on a photoconductive surface. The electrostatic images are developed and transferred to a copy substrate material as in conventional xerographic systems. A flying spot light beam is provided in a second WRITE mode, the flying spot beam writing images on the photoconductive surface in response to image signals input thereto. In this mode of operation, the beam impinges on the photoconductive surface at a location upstream of the developing device. And, in a third READ mode, the beam is impinged on the photoconductive surface downstream of the developing device to scan images developed on the photoconductive surface. The scattered light is collected and converted to image signals representative of the image scanned. In an alternate embodiment, the flying spot beam impinges on the photoreceptor at a single location upstream of the developing device for both WRITE and READ modes. To preserve the developed image for scanning by the flying spot beam in the READ mode, the…
