Dual mode document feeder

摘要

A document feeder includes a feed tray which is pivotal about a horizontal axis between an elevated automatic position in which it can be locked and in which the uppermost document of a stack of documents thereon is engaged with an endless belt skimmer to be fed from the stack, and a lowered manual position away from the skimmer for manual feed of a single document. A reverse feed roller is movable with the feed tray and is operative in the automatic position to inhibit feed of documents other than the uppermost document of a stack.
