Description

本発明は、シート束を綴じる綴じ装置であって、シートを搬送する搬送部と、前記搬送部により搬送されたシートを積載する積載部と、前記綴じ装置の奥行方向において前記積載部よりも手前側に配置され、操作者によってシート束が挿入される手差しセット部と、ステープル針を収納するカートリッジが着脱可能に設けられ、前記ステープル針を用いてシート束を綴じるステープラと、前記積載部に積載されたシートからなるシート束の前記奥行方向における奥側の角部を綴じるための第１綴じ位置と、前記奥行方向において前記第１綴じ位置よりも手前側で前記手差しセット部に挿入されたシート束を綴じるための第２綴じ位置と、前記奥行方向において前記第１綴じ位置よりも手前側で前記ステープラから前記カートリッジを取り外して新たなカートリッジを装着するためのカートリッジ交換位置に前記ステープラを移動させるステープラ移動機構とを備え、前記ステープラが前記カートリッジ交換位置にある状態において、前記ステープラに装着されている前記カートリッジは、前記ステープラから前記カートリッジを取り外す方向における下流端部が、前記ステープラから前記カートリッジを取り外す方向における上流端部よりも前記奥行方向において手前側に位置している、ことを特徴とする。 The present invention is a binding device for binding a bundle of sheets , comprising: a conveying section for conveying sheets ; a stacking section for stacking the sheets conveyed by the conveying section ; a manual setting unit disposed in front of the unit and into which a sheet bundle is inserted by an operator; and a stapler, which is detachably provided with a cartridge containing staples and which binds the sheet bundle using the staples. a first binding position for binding a rear corner portion in the depth direction of a sheet bundle composed of sheets stacked on the stacking portion ; a second binding position for binding the sheet bundle inserted into the unit; and a cartridge replacement position for removing the cartridge from the stapler and installing a new cartridge on the front side of the first binding position in the depth direction. and a stapler moving mechanism for moving the stapler in a state in which the stapler is at the cartridge replacement position, the cartridge attached to the stapler has a downstream end in a direction of removing the cartridge from the stapler, It is characterized in that it is located on the nearer side in the depth direction than the upstream end portion in the direction in which the cartridge is removed from the stapler .

Claims

A binding device for binding a sheet bundle,
a conveying unit that conveys the sheet;
a stacking unit for stacking the sheets conveyed by the conveying unit ;
