ABSTRACT:
A sheet feeder in which a picker member engaging an end sheet of a stack is actuated to drive the end sheet through a feed nip formed by a feed member and a cooperating member. The picker member is actuated in advance of the feed member to prevent other sheets from entering the nip. Preferably, the picker member is preactuated by coupling it directly to the drive source while coupling the feed member to the same drive source through an electrically actuated clutch.
