Abstract

A "scuffer wheel" device for driving a document sheet into registration over a platen 2 in a copier document handler. There is a pivotable document overlying plate or ski 3 extending between the scuffer wheel 4 and the registration stop 5 to confine document buckling and prevent the document lead edge from jumping over the top of the stop 5. The scuffer wheel 4 is mounted to the plate 3, preferably through a slot 6 allowing partial independent lifting movement of the ski 3. Figure 1 illustrates the normal position and Figure 2 a lifted portion of the ski 3 with a wrinkled document 1. Figure 3 is a partial top view.

DOCUhqENT REGISTRATION WITH "SIQ' ASSISTED SCUFFER. WHEEL (Cont'd)

The normal and driving force of the scuffer wheel is partially self-limiting in that excessive buckling of the document lifts up the ski 3 and also thereby pushes up against the scuffer wheel 4. However, the limited slot 6 allows the ski 3 to lift slightly to accommodate a wrinkled document without lifting the scuffer wheel 4. It is an improvement on a ski-scuffer device (disclosed for a sorter bin) in U.S. Patent No. 4,087,087 issued May 2, 1978 to John H. Looney.
