Abstract

A document stacker assembly including a plurality of document stackers each having a bin wherein documents are selectably stacked against a bin wall member. A belt moves documents along a document track and an idler wheel is pressed against the belt in each stacker assembly. A flicker wheel is driven to rotate by pressure thereagainst by the rotating idler wheel. A solenoid is operable selectably to move a document deflector pivoted about the flicker wheel axle to deflect a document along the track into the pinch between a central waisted portion of the flicker wheel and the idler wheel. The document is urged into the bin and the trailing edge of the document, having disengaged from the pinch between the idler wheel and a waisted portion of the flicker wheel is engaged by projections on the unwaisted top and bottom serrated portions of the flicker wheel, to urge the document further into the bin and to disengage the trailing edge at a predetermined location therein.
