A damping apparatus has a first damper mechanism positioned at a leading end of a sheet which is introduced into a sheet stacking region, for movement in the direction A away from the sheet stacking region to absorb shocks produced by the sheet when the sheet hits the first damper mechanism, and a second damper mechanism combined with the first damper mechanism, for movement in the direction A away from the sheet stacking region to absorb the shocks produced by the sheet S while the shocks produced by the sheet are being absorbed by the first damper mechanism and then after the first damper mechanism starts moving back in the direction B toward the sheet stacking region. Sheets can successively be introduced at a high speed into the sheet stacking region, and are effectively prevented from being folded or improperly positioned in the sheet stacking region.
