A sheet stacking device, comprised of a sheet support bed having a plurality of side-by-side rollers that are freely rotatable about an associated roller axis. A drive assembly moves the sheet support bed in a predetermined direction along a closed path. The path has a horizontal upper run and a horizontal lower run, and is dimensioned such that a space exists between the first end and the second end of the sheet support bed as the sheet support bed moves along the path. A roller control assembly for selectively and sequentially controls rotation of select ones of the rollers at select intervals during a stacking operation, wherein the stacking device is operable to: receive a sheet to be stacked on the sheet support bed when the support bed is disposed along the upper run; convey the sheet along the upper run on the support bed to a &ldquo;stacking position&rdquo; on the upper run; and cause the roller control assembly to drop the sheet through the space between the first and the second end of the sheet support bed to a stacking location below the upper horizontal run.
