Abstract

A recirculating document handler apparatus 1 is disclosed in Figure 1 for repeatedly recirculating a set of documents for precollation copying. The documents are repeatedly individually fed seriatim from platform 5 and the bottom of the stack 7 for copying in a precise registration position on two axis of copier platen 3, in the direction of document movement-and laterally thereof, and returned to the top of the document stack supported in tray 60 as shown in Figure 2. Tray 60 has improvements therein for automatically edge registering documents in the tray that insures non-skewed feeding of documents during high performance operation of the document handler.

AUTOMATIC RESTACKING REGISTRATION IN A RECIRCULATING DOCUMENT HANDLER (Cont'd)

A recirculating document handler apparatus 1 is disclosed in Figure 1 for repeatedly recirculating a set of documents for precollation copying. The documents are repeatedly individually fed seriatim from platform 5 and the bottom of the stack 7 for copying in a precise registration position on two axis of copier platen 3, in the direction of document movement-and laterally thereof, and returned to the top of the document stack supported in tray 60 as shown in Figure
2. Tray 60 has improvements therein for automatically edge registering documents in the tray that insures non-skewed feeding of documents during high performance operation of the document handler.

The improvements among other things include straight ramps 63 and 65 attached to side wall or guide 62 and raised support surface 68, respectively. The ramps are slightly inclined to an appropriate degree. Also, corner and other restrictions from a portion of end wall 61 are removed to allow free flow of air in a non- concentric manner which favors the rear corner of the tray. With these features in the tray, documents are aligned along the side of side guide 62 by airflow froin air knife 12, i.e., no additional lateral registration means is necessary.

Airflow from the air knife 12 automatically moves the documents toward the registration c...
