ABSTRACT:
Apparatus for successively presenting sheets for inspection by a keyboard operator or the like who must with a both hands otherwise occupied. A support inclined upwardly from a discharge end spaced above the work table holds a stack of sheets to be fed. A feed roller disposed across the discharge end in engagement with the upper side of the stack is energized to advance sheets successively therefrom, while a plurality of frictional retarding elements disposed across the discharge end in engagement with the lower side of the stack prevent the feeding of more than one sheet at a time. The retarding elements are urged against the stack with greater biasing force near the center of the discharge end than at the edges thereof to provide an automatic centering action.
