Zusammenfassung:To provide a sheet binding device mounted with a needleless binding mechanism and a needle binding mechanism, which is configured so that when the needleless binding mechanism is arranged closer to a front side of the device than the needle binding mechanism, needles can be replenished into the needle binding mechanism, with a compact structure.SOLUTION: A needleless binding unit 27 is arranged closer to a front side of a device than a staple unit 17. When needles are replenished into the staple unit 17, the staple unit 17 is moved to a needle replenishing position. In so doing, the needleless binding unit 27 is retreated to a position which is closer to the front side of the device than the staple unit 17 in a sheet width direction and closer to the front side of the device than the needleless binding position of the needleless binding unit 27.SELECTED DRAWING: Figure 16 【課題】針無し綴じ機構及び針綴じ機構を搭載したシート綴じ装置において、針無し綴じ機構を針綴じ機構よりも装置フロント側に配置した場合に、コンパクトな構成で針綴じ機構への針補充を行うことができるシート綴じ装置を提供する。【解決手段】ステープルユニット17よりも装置フロント側に針無し綴じユニット27が配置されており、ステープルユニット17に対して針補充を行う場合はステープルユニット17を針補充位置に移動する。その際、針無し綴じユニット27はシート幅方向においてステープルユニット17よりも装置フロント側で且つ針無し綴じユニット27による針無し綴じ位置よりも装置フロント側に退避させる。【選択図】図16
