A sheet discharging device includes a shift trayon which a sheet Pis stacked, a discharging rollerthat discharges a sheet Ponto the shift tray, a blowing devicethat sends air to a lower surface of the sheet Pdischarged by the discharging roller, a blocking memberthat blocks air sent to the lower surface of the sheet Pfrom a blowing port-of the blowing device, and a control unit that controls the blocking amount of the blocking member. The blocking amount is determined based upon sheet information including sheet-type information, sheet-size information, and sheet-thickness information, for example.

Sheet discharging device, image forming system, and sheet discharging method

A sheet discharging device includes a shift trayon which a sheet P1 is stacked, a discharging rollerthat discharges a sheet P2 onto the shift tray, a blowing devicethat sends air to a lower surface of the sheet P2 discharged by the discharging roller, a blocking memberthat blocks air sent to the lower surface of the sheet P2 from a blowing port-of the blowing device, and a control unit that controls the blocking amount of the blocking member. The blocking amount is determined based upon sheet information including sheet-type information, sheet-size information, and sheet-thickness information, for example.

A sheet stacking apparatus including: a discharge unit configured to discharge a sheet through a discharge port; a stack unit configured to stack the discharged sheet thereon; and a plurality of blowing units configured to supply air to a discharge side of the discharge unit while the sheet is discharged, wherein the blowing units are disposed, below the discharge port, aligned with a direction perpendicular to a sheet discharge direction.

Sheet stacking apparatus, image forming system and sheet stacking method

A sheet stacking device includes: a stacking unit that stacks thereon a sheet discharged in a sheet discharging direction; a conveying unit that performs a moving-back operation of conveying the stacked sheet in a direction opposite to the sheet discharging direction; a pressing unit that performs a pressing operation of pressing the conveyed sheet; and a driving unit that drives the conveying unit and the pressing unit by a same driving source.
