Abstract

A multiple function image processing system have both a lighthens 5, 6 for exposing document originals 7 on a platen 8 to a charged photoreceptor 9 and a flying spot image writing beam 10 for exposing the charged photoreceptor 9 in response to video image signals input to modulator 12. The images formed on photoreceptor 9 are developed by developer 13 and transferred at 14 to copy substrate material 15. The photoreceptor 9 is thereafter cleaned by brush 16 and charged by corotron 17 preparatory to re-exposure.

15. The photoreceptor 9 is thereafter cleaned by brush 16 and charged by corotron 17 preparatory to re-exposure.

A toner image reading beam 18, which is derived from laser 19 through beam splitter 20, is scanned across the photoreceptor surface downstream of developer 13 by rotating deflector 21. Light striking the photoreceptor and the developed image thereon is scattered and reflected, and the light is collected by collector
23. One or more photosensors in collector 23 transform the collected light into video image signals.

COPY REPRODUCTION APPARATUS

Where multiple copies of document original 7 are desired, original 7 is exposed, using light/lens 5, 6 and the latent electrostatic image created on photoreceptor 9 developed by developer 13. The developed image is scanned prior to transfer by image reading beam 18 and the...
