Abstract

A sheet discharging device has a sheet support, a sheet discharge part, a detector and means for controlling the transport condition at the time of sheet discharge. The detector detects the length or characteristic of a sheet before its discharge. Thus a transport condition of a sheet can be changed at the time of its discharge dependent on its length or characteristic and the sheet is discharged adjustably.
