Abstract
In a recirculating document handling apparatus for a copier, in which a set of document sheets are sequentially circulated from a stack thereof to the imaging station of the copier and back to the stack, and in which selectable inverting apparatus is provided for inverting or not inverting the document sheets as they are being so circulated and before they are returned to the stack, the latter comprises a large diameter inverting roller adjacent the downstream side of the imaging station, normally rotated in a first direction, and selectably rotated in the reverse direction, and a repositionable wedge-shaped first sheet guide provides in a first position, a document sheet first path from said imaging station around the outside of said inverting roller and towards the stack with the inverting roller driven in the first direction, and said first guide being repositionable to a second position, in coordination with said reverse rotation of said inverting roller in which a document sheet is guided in a second path around the inside of said inverting roller (between the inverting roller means and the imaging station) and then to the outside of the inverting roller, the reverse rotation of the inverting roller being sufficient to rotate the trail edge of a document sheet in this second path past a second guide means adapted to allow the trail edge of the document sheet to flip relative thereto so that upon re-reversal of the inverting roller the document sheet is fed toward the stack trail edge first.
