Abstract
A suction conveyor conveys sheets which are stacked in a hopper of a sheet stacker. The suction conveyor includes a suction box and a suction belt that cycles along the surface of the suction box. Porous sections, having sets of suction holes or the like, are formed intermittently at a prescribed pitch on the suction belt. The leading section of the sheet is suctioned to these porous sections, and the sheets are conveyed by the motion of the belt. A scraper at a terminal end region of the conveyance path forcibly peels off the sheet from the porous sections of the suction belt. The sheets are dropped down with the trailing end dropping before the leading end and are stacked in the hopper.
