Summary:PROBLEM TO BE SOLVED: To prevent a sheet loaded on a process tray from being pushed out by a gripper.SOLUTION: A sheet processing device includes a process tray 29 in which a sheet is loaded, a gripper 105 which approaches the process tray to grip a sheet loaded on the process tray, to move the sheet along the direction for shipping from the process tray, and a control part which makes control to delay an approach moving speed Ve of the gripper to the process tray when the number of loaded sheets is a predetermined number or less based on the loading sheets information of the sheets loaded on the process tray. Since the approach moving speed of the gripper to the process tray becomes slower when the number of loaded sheets is a predetermined number or less, a sheet is never to be pushed out even if the gripper in opened state rubs against a portion of the sheet that deflects downward. 【課題】処理トレイに積載されたシートがグリッパによって押し出されないようにすること。【解決手段】シート処理装置は、シートが積載する処理トレイ29と、処理トレイに接近移動して、処理トレイに積載されているシートを把持し、該シートを処理トレイから搬出する方向へ移動させるグリッパ105と、処理トレイに積載されるシートの積載枚数情報に基づくシートの積載枚数が所定枚数以下のとき、処理トレイへのグリッパの接近移動速度Veを遅くする制御をする制御部と、を備えている。シートの積載枚数が所定枚数以下のとき、処理トレイへのグリッパの接近移動速度が遅くなるので、開口状態のグリッパがシートの下方に撓んだ部分を擦ることがあっても、シートを押し出すようなことがない。【選択図】図28
