ABSTRACT:
A plunger moves from a retracted position to an extended position to engage a document which is on a receiving platform to push the document through an opening in the receiving platform and towards a stacking platform to stack the document on the stacking platform. The plunger moves from the extended position back to the retracted position to allow a biasing force which is acting on the stacking platform to press the document which has just been stacked on the stacking platform against the receiving platform. A supporting mechanism supports first and second plate members of the receiving platform for pivoting movement between a non-parallel position in which the plate members form a substantially wide V-shape to cup the document as the plunger pushes the document through the opening and onto the stacking platform, and a parallel position in which the plate members are substantially parallel to each other as the plunger moves back to the retracted position to allow the biasing force which is acting on the stacking platform to press the document which has just been stacked on the stacking platform against the receiving platform.
