A sheet stacking device as defined in claim 5, wherein when said friction belt in said first operating condition engages select ones of said rollers and moves with select ones of said rollers at a speed equal to the speed of said sheet support bed in a direction that is the same as the direction of said sheet support bed along said path, and in said second operating condition engages said rollers and is stationary. 7. A sheet stacking device as defined in claim 6, wherein said friction belt engages said rollers at the longitudinal ends of said rollers. 8. A sheet stacking device, comprised of: a sheet support bed having a first end and a second end, said sheet support bed comprised of a plurality of side-by-side rollers, each of said rollers being freely rotatable about an associated roller axis; a drive assembly for moving said sheet support bed in a predetermined direction along a closed path, said path having a horizontal upper run and a horizontal lower run and being dimensioned such that a space exists between said first end and said second end of said sheet support bed as said sheet support bed moves along said path; and a roller control assembly operatively engaging said rollers for selectively and sequentially controlling rotation of select ones of said rollers at select intervals during a stacking operation, wherein said stacking device is operable to: receive a sheet to be stacked on said sheet support bed when said sheet support bed is disposed along said upper run; convey said sheet along said upper run on said sheet support bed to a stacking position on said upper run; and cause said roller control assembly to rotate rollers disposed along said upper run in a direction such that said sheet remains essentially in said stacking position as said sheet support bed continues to move along said path, said sheet dropping through said space between said first and said second end of said sheet support bed to a stacking location below said upper horizontal run. 9. A sheet stacking device as defined in claim 8, wherein said roller control assembly includes a frictional surface engageable with select ones of said rollers that move along said upper run, said frictional surface movable between a first position wherein said frictional surface is not in engagement with said rollers and a second position wherein said frictional surface is in engagement with said rollers. 10. A sheet stacking device as defined in claim 9, wherein said frictional surface is movable with said roller along said upper run. 11. A sheet stacking device as defined in claim 10, wherein said frictional surface is an endless flexible belt that is movable along a path having a portion that extends generally parallel to said upper run. 12. A sheet stacking device as defined in claim 11, further comprising a controllable drive motor for conveying said belt along said path. 13. A sheet stacking device as defined in claim 12, wherein said flexible belt is disposed along one end of said rollers. 14. A sheet stacking device as defined in claim 8, further comprising a controller for controlling the timing and operation of said drive assembly and said roller control assembly. 15. A sheet stacking device as defined in claim 14, further comprising a scanning device for detecting defects or imperfections on a sheet to be stacked, said scanning device providing data to said controller when a defective sheet is scanned. 16. A sheet stacking device as defined in claim 15, wherein said controller upon receiving data from said scanning device indicating a defective sheet modifies the operation of said roller control assembly to convey said sheet along said upper run on said support bed to be conveyed past said stacking position and off said device. 17. A sheet stacking device, comprised of: a sheet support bed having a first end and a second end, said sheet support bed comprised of a plurality of si
