Recirculating Document Feed with Dual Entry Gate

The recirculating document feed associated with a copier or the like accepts a second original to be copied in a standby position until after a preceding original is recirculated to produce a preselected number of copies.

Copier 10 has a relatively fixed original document scanning station 12 which scans the document image as it passes over 12 in paper path portion 14. The image is transferred through station 12 to a photoconductor or the like in a conventional manner for fixed scan copiers. The first document to be copied is inserted at input chute 15 and encounters feed rollers 17 and closed gate 16. The user, by means not shown, instructs copier 10 as to the number of copies to be made. Copier 10 then opens gate 16 and allows the document to proceed until it encounters gate 18. Gate 16 closes lightly on the document in entry chute
15.

At the proper time, the second gate 18 opens, allowing the document to pass the imaging scanner area 12 in paper path 14. If multiple copies have been selected, output gate 20 is in the solid position, as shown, so as to divert the documents as they pass from the nip between rollers 21 and 22 into the upwardly directed path 24. Thus, the document returns by means of rollers 21-23 and 25-27 to gate 18. The timing controls (not shown) then release gate 18 and thus the document for the next copy, and the recirculation continues until the appropriate number of copies have been made. Gat...
