A document handling system adapted for delivery of documents to an imaging station of an imaging input terminal. The system includes a driven friction belt for transporting the documents across a platen of the imaging station. The belt is urged into planar orientation with the platen by slider plates which are ski-like members that bear upon the belt. The slider plates are arranged to bear upon the margins of the imaging area to smooth documents on the belt and to urge such document onto the platen thus providing an improved imaging of documents delivered to the imaging station.

Why it's free to use
- Filed September 24, 1992 and granted December 9, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 24, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 24, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
