ABSTRACT:
A reciprocating sheet pusher for ejecting a topmost sheet of a stack of sheets outward seriatim from a sheet receiving bin having sheet ejecting support structure attached to a pusher arm which carries a roller ejecting element. A piece of stiff firm hair material affixed to the support structure clutches with controlled predetermined friction the axially supported rubber roller to resist movement on a forward sheet ejecting stroke of the reciprocating sheet pusher. If a predetermined resistance against a jammed sheet or an empty bin is encountered, the roller ejecting element rotates with limited controlled friction. The roller ejecting element rotates unrestrained when the sheet pusher moves in an opposite direction to that of ejecting a sheet.
