Description

本発明は、シートを束状に集積して綴じ処理するシート束処理装置の改良に関する。 The present invention relates to an improvement in the sheet bundle processing equipment to binding processing by integrating sheet over preparative in a bundle.

圧着綴じ処理の際には、押圧部の凹凸形状の加圧面をシートに強く押しつけるため、シートが押圧部の加圧面に食いついた状態となってしまう虞がある。 During crimping binding process is for pressing strongly pressing surface of irregular shape of the press pressure portion in sheet, Ru a danger of sheet becomes a state of bite the pressure surface of the pressing portion.

上記目的に鑑み、本発明のシート処理装置は、シートが載置されるシート載置部と、前記シート載置部に載置されたシートを変形させて、針無しで綴じる綴じ部材と、前記綴じ部材により綴じられたシートに回転力を付与することによって該シートと前記綴じ部材とを剥がす剥がし部材と、第一の位置と、前記第一の位置とは異なる第二の位置とにおいて、前記剥がし部材により前記綴じ部材により剥がされたシートに力を作用させて、該シートの姿勢を矯正する、姿勢矯正部材と、を備え、前記綴じ部材によって綴じられたシートが前記シート載置部から排出される際の排出方向と直交する方向に関して、前記綴じ部材によりシートが綴じられたときの該シートの中心は、前記直交する方向に関して、前記第一の位置と前記第二の位置との間に位置する。 In view of the above-described object, the sheet processing apparatus of the present invention includes a sheet placement unit on which a sheet is placed, a binding member that deforms the sheet placed on the sheet placement unit, and binds the needle without a needle, A peeling member that peels off the sheet and the binding member by applying a rotational force to the sheet bound by the binding member; a first position; and a second position different from the first position. peeled wherein the sheet is peeled by stapling member by applying a force of a member, to correct the posture of the sheet, and the posture correction member, wherein the sheet stapled by the stapling member from the sheet placement portion with respect to the direction perpendicular to the discharge direction when being discharged, the center of the sheet when the sheet is stapled by the stapling member, in the direction of the orthogonal, and said second position and said first position Located in.

綴じ部材にシートが食いついてしまった場合でも、綴じ部材からシートを引き剥がすことができる。 Even if the binding member sheet had bite, it is possible to peel the sheet from the binding member.

Claims
