ABSTRACT:
An improved retard type sheet feeder with sheet separation for sequentially feeding individual sheets from a stack of the sheets, with particular utility for a bottom sheet (bottom of stack) separator/feeder which may be used in low cost document feeders for copiers. A low cost retard member mounting system prevents tilting or other undesired movement of the retard pad in the direction of sheet feeding, and allows only desired vertical movement [spring loading restricted] plus desired free lateral tilt for lateral pivotal self-leveling with respect to the opposing sheet feeding member. The retard pad sheet engagement surfaces and the opposing sheet feeding member engaging surface are shaped and positioned to optimize stack sheet separation and feeding while minimizing varying, uneven or localized high pressure points which could induce image smearing, vibration or other difficulties, cooperatively with and assisted by the mounting system.
