Summary:To allow an operator to easily take out a sheet bundle discharged onto a loading tray and subjected to the needle-less binding processing in a sheet processing apparatus.SOLUTION: A sheet processing apparatus for loading sheets subjected to post-processing on a processing tray 40 onto a loading tray 26 by discharging the sheets in the discharge direction includes: a needle-less binding device 57b; a neat alignment device which aligns the sheet bundle discharged onto the loading tray 26 with a prescribed position on the loading tray 26 by a pair of neat alignment plates 73 that can approach or separate with respect to each other in the width direction orthogonal to the discharge direction; and a neat control unit which controls the operation of the neat alignment device. When the sheet bundle subjected to the needle-less binding processing by the needle-less binding device 57b is discharged to the loading tray 26 from the processing tray 40, the neat control unit controls the sheet bundle to perform offset movement in the width direction on the loading tray 26 with the movement in the width direction of the pair of neat alignment plates 73 of the neat alignment device.SELECTED DRAWING: Figure 10 【課題】シート処理装置において、積載トレイ上に排出された針なし綴じ処理を施されたシート束を操作者が取り出しやすくする。【解決手段】シート処理装置は、処理トレイ40上で後処理を施されたシートを排出方向に排出して積載トレイ26上に積載するものであり、針なし綴じ装置57bと、排出方向と直交する幅方向に互いに対して接近離反可能な一対のニート整合板73により積載トレイ26上に排出されたシート束を積載トレイ26上の所定の位置に整合させるニート整合装置と、ニート整合装置の動作を制御するニート制御部とを備え、針なし綴じ装置57bにより針なし綴じ処理を施されたシート束が処理トレイ40から積載トレイ26に排出されたときに、ニート制御部がニート整合装置の一対のニート整合板73の幅方向の移動により積載トレイ26上でシート束を幅方向にオフセット移動させるようにする。【選択図】図10
