Abstract

A document handling apparatus includes a friction retard feeder for feeding documents from a stack. The friction retard feeder has a feed belt and a retard pad with a concaved portion as well as an inclined, but essentially straight stepped portion that shingles the documents in order to inhibit multifeeding, stubbing and reduce image abrasion of documents during feeding.
