Abstract
A stapler includes an enclosing portion that encloses staples, a clinch portion that bends a staple, and a projecting portion that projects the staple from the enclosing portion, inserts the staple to a sheet bundle, and bends the staple in cooperation with the clinch portion to bind the sheet bundle. In addition, a guide portion guides the staple projected by the projecting portion toward the sheet bundle. The guide portion has guide surfaces for guiding the staple from an inlet adapted to receive the inserting ends of the staple to an outlet that is formed narrower than the inlet such that the staple is projected by the projecting portion toward the sheet bundle side, and the projecting portion projects the staple to the guide portion, moves the staple along the guide surfaces to deform the staple in a horseshoe shape, inserts the pair of inserting ends to the sheet bundle, and bends the staple in cooperation with the clinch portion to bind the sheet bundle.
