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 pat

Abstract: An arrangement is disclosed for combining the capability for bound document copying with a document handling apparatus in a reproduction machine. To this end, an arrangement is devised wherein the document handling apparatus is contained within a frame which contains a light-tight cover for bound documents having three-dimensional shape. The arrangement includes a pivoting connection between the document handling apparatus and the frame relative to the platen of the reproduction machine and between each other so as to permit access to the platen for manual document placement and bound document copying.

Abstract: A double latch arrangement is disclosed for use in a reproduction system having a document handling device for the circulation of individual document sheets onto a copying exposure platen and a separate bound document copying apparatus. The latching mechanism is devised which will secure together both the document handling device with the bound document copying apparatus so as to be movable as a unit relative to an exposure platen of the reproduction system, or to permit only the document handling device to be so moved.

Abstract: A cover arranged to hold an original document in the platen of an electrophotographic printing machine. The cover includes an outer member defining a chamber with an inner member being mounted therein. The outer member cooperates with the platen to form a light-tight seal while the inner member presses the original document thereagainst.
