ABSTRACT:
A picking member (72) rotates to cause a sheet to be picked from a stack (42) of sheets. The picking member includes movable engaging portions supported on arcuate segments (128, 144). The engaging portions move radially outward to apply additional moving force to an end sheet bound in the stack responsive to movement of the picking member exceeding the movement of the end sheet.
