Abstract
A sheet feeder apparatus having a feed roller, a reverse roller, a movable sheet support platform for furnishing sheets from a stack to the feed roller, and a pivotable arm with pickup roller for engaging the stack of sheets on the support platform. The sheet support platform is spring driven and equipped with a brake mechanism operable responsive to movement of the pivotable arm which is caused by feeding of sheets from the stack, thereby to permit the spring to drive the sheet support mechanism into further feeding disposition. The nip between the feed roller and reverse roller of the apparatus may be selectively controlled to accommodate sheets of various thicknesses by means of a pivot shaft connected to the reverse roller, which shaft has a levered end engaging a manually operated adjustment cam and release lever mechanism.
