PROBLEM TO BE SOLVED: To provide a sheet ejecting technology when ejecting a processed sheet to an ejecting tray lower by one stage than a processing tray from the processing tray.SOLUTION: A sheet processing device includes a processing tray, a processing part, an ejecting tray, a support mechanism, an ejecting claw and a control part. The support mechanism can move between a support position for supporting an under surface of a projecting part of projecting to the ejecting tray side from above the processing tray of the sheet placed on a placing surface of the processing tray so as not to abut on the placing surface of the ejecting tray, and an unsupporting position for not supporting it. The ejecting claw pushes an upstream side end in the sheet moving direction of the sheet on the processing tray, and moves the sheet placed on the processing tray to the ejecting tray. The control part moves the sheet placed on the processing tray to the ejecting tray by the ejecting claw and sets the support mechanism to the unsupporting position from a state of supporting the under surface of the projecting part by the support mechanism existing in the support position, so as to drop the sheet on the ejecting tray. |
