Abstract:
A sheet stacking apparatus includes a discharging portion including a nip portion nipping and conveying a sheet, a stacking portion on which the sheet discharged by the discharging portion is stacked, an air blowing unit configured to blow air toward a lower face of the sheet being discharged by the discharging portion, and an air volume control portion configured to control the air blowing unit such that a volume of the air blown by the air blowing unit is switched from a first air volume to a second air volume which is smaller than the first air volume while the nip portion of the discharging portion is nipping and conveying the sheet to set the volume of the air to the second air volume in a case where a trailing end of the sheet discharged by the discharging portion passes through the nip portion.

Claim (Index 18):
A sheet stacking apparatus comprising:\n a discharging portion comprising a nip portion nipping and conveying a sheet, and configured to discharge the sheet; a stacking portion on which the sheet discharged by the discharging portion is stacked; an air blowing unit configured to blow air toward a lower face of the sheet being nipped by the nip portion; and a control portion configured to execute a first mode in a case where a length of the sheet to be discharged by the discharging portion in a sheet discharging direction is a first length and a second mode in a case where a length of the sheet to be discharged by the discharging portion in the sheet discharging direction is a second length longer than the first length, the first mode being a mode where the air blowing unit does not change a volume of the air to the sheet while the nip portion of the discharging portion is nipping and conveying the sheet, and the second mode being a mode where the air blowing unit changes the volume of the air from a first air volume to a second air volume which is smaller than the first air volume while the nip portion of the discharging portion is nipping and conveying the sheet.
