Immediately after a clinch lever causes a clinch link to clinch the leg of a staple which penetrates sheets of paper to be stapled, a pressure by the clinch lever with respect to the clincher link is temporarily reduced by a pressure reducing unit. Therefore, a clincher moves down in a state where the clincher still receives the press-contacting force from a driver plate. Accordingly, the looseness occurs between the driver plate and the clincher link. A fixing plate becomes easy to draw out as much as the looseness. If the fixing plate is set to be drawn out at this timing, it can be simply drawn out to be moved to the initial position. |
