Abstract

A controlled velocity transport 10 is disclosed in the figure that is capable of making single or multiple copies from documents or books. An individual document is copied by passing it into a registration aid that includes a normal force ball 12 and a slanted drive roller 13 which registers it against a side of the copier 20 while forwarding it toward a nip defined by two rollers 14 and 15. The rollers in conjunction with a second pair of rollers 16 and 17 move the document at a fixed rate past a stationary optical system 40 which includes platen 41, lamp 42 and lens 43. The optical system transmits incremental portions of the document to a charged photoreceptor for document imaging. If multiple copies are desired of the document, gate B is actuated to intercept the document and deflect it into a race track loop past drive roll 18 and onto platen 41 for imaging as many times are required. For a large document, multiple copies are made by actuating gate A as the document leaves drive rollers 16 and 17. The document will then be deflected into the race track loop and returned to the platen 41.

A controlled velocity transport 10 is disclosed in the figure that is capable of making single or multiple copies from documents or books. An individual document is copied by passing it into a registration aid that includes a normal force ball 12 and a slanted drive roller 13 which registers it against a side of the copier 20 while forwarding it toward a nip defined by two rollers 14 and 15.

In the book copying mode, controlled velocity transport 10 separates at the plane X by pivoting housing 11 to the rear as viewed in the figure on an articulating hinge (not shown) which allows the h...
