Abstract:
In a sheet stacking tray system for stacking different sizes of copy sheets to be fed upstream to a reproduction apparatus for the printing of said copy sheets, said stacking tray system having a stack supporting tray and plural upstanding stack edge guides for engaging at least two sides of a stack of copy sheets on said stack supporting tray, and wherein said plural stack edge guides are repositionable relative to said stack supporting tray for engaging at least two orthogonal edges of different sizes of a stack of copy sheets stacked on said stack supporting tray, and wherein a registration edge position is provided for registration of one side of said stack of copy sheets stacked on said stack supporting tray aligned with said upstream direction; wherein one said upstanding stack edge guide comprises;a track-mounted upstanding stack rear edge guide which is track-mounted for an elongated range of angular repositioning movement in both said upstream direction and in the direction of said registration edge position to engage a wide range of said different sizes of copy sheets stacked on said stack supporting tray;said elongated range of angular repositioning movement of said track-mounted upstanding stack rear edge guide engaging larger sheets stacked on said stack supporting tray further from said registration edge position and engaging smaller sheets stacked on said stack supporting tray closer to said registration edge position; andat least one other said upstanding stack edge guide comprising an upstanding stack side edge guide which is repositionable transversely to said registration edge position independently of any position of said upstanding stack rear edge guide,said upstanding stack side edge guide having a defined elongated repositioning movement range transversely to said registration edge which does not overlap with said elongated range of angular repositioning movement of said track-mounted upstanding stack rear edge guide.
