Abstract (en)

[origin: EP0033594A2] A copying apparatus and image processing method. For a first COPY mode, a light/lens (15,16) is used to expose originals (13) at a viewing station or platen (12) and produce latent electrostatic images thereof on a photoconductive surface (19). The electrostatic images are developed and transferred to a copy substrate material (28) as in conventional xerographic systems. For a second WRITE mode, a flying spot beam (61) writes images on the photoconductive surface at a location upstream of the developer (22) in response to image signals input thereto. For a third READ mode, the beam is impinged on the photoconductive surface downstream of the developer and scans across images developed on the photoconductive surface. The reflected light is collected (100) and converted (108, 108 min ) to image signals representative of the image scanned. In another embodiment, the beam impinges on the photoreceptor at a single location upstream of the developer for both WRITE and READ modes.
