Scanning Fiber Optic Bundle Copier with Recirculating Document Feed

This article describes a xerographic copier with accurately scanning fiber- optic bundle which includes pivotable Recirculating Automatic Document Feed (RADF).

Drum 10 has a photoconductive surface and is imaged by elongated fiber- optic lens array 11. RADF 12 (in the position shown) accepts original documents from input tray 15 and impels them by means of rollers 16-19 past lens array 11 which is held in a parked position, thereby imaging drum 10. After passing the parked optic area, gate 20 is either positioned to return the documents as between rollers 21-18 and 22-16 to the original starting position for rescanning, or causes them to be deposited in output tray 23. The image on drum 10 is processed in a conventional manner as by developer 25, copy sheet handling apparatus 26, corona 27, and the like.

When large documents, books, or the like are to be copied, RADF 12 is raised (to the position shown in dashed lines) so that curved platen 30 is accessible to the user. Fiber-optic bundle 11 is then scanned through a segment of an arc to the position shown at 31, thereby imaging drum 10 with the document on platen 30.

Although dual illumination lamps can scan with fiber-optic assembly 11, if desired, heat reduction can be obtained by employing a fixed fluorescent lamp 35 with an incandescent lamp 36 that is movable with fiber-optic assembly 11 to position 31.
