Abstract
Improvement to an apparatus for singulating respective documents fed thereto, the apparatus comprising first document feeding structure including first and second document feeding structure adjacent one another. The improvement is to the second document feeding structure and comprises a first section including an upstream end and a downstream end, the upstream end being pivotally mounted to a frame member, and including at least two outboard endless belts therearound and second structure for moving the outboard belts upstream relative to a path of travel in vertically spaced second belt runs; and a second section having at least two inboard endless belts therearound. The second section is pivotably mounted at one end to the first section. There is structure for coupling movement of the outboard belts of the first section to movement of the inboard belts of the second section for driving the inboard belts of the second section upstream relative to a path of travel in vertically spaced second section belt runs; and structure for resiliently urging the second section belt runs into interleaving relationship with the first belt runs, and for resiliently urging the downstream end of the…
