Bill stacker

摘要

An improved bill stacker (40) is described that effectively rolls incoming bills (38) onto the stack. In one aspect of the invention, the bill stacker (40) includes a housing that encloses a stacking plate (46) that is arranged to support a stack of bills. A gripper (48) is typically provided to grab the leading edge of an incoming bill (38) and a stack roller (50) is arranged to travel longitudinally relative the stacking plate (46) to "roll" a newly received bill (38) onto a top end of the bill stack (44) (if present) or the stacking plate (46) when the first bill is being received. A variety of methods of stacking bills in a cash box (40) using the concept of rolling an incoming bill (38) onto the top of a stack (44) are also described.
