Claim:
A stapler for binding a binding object with staples having a pressing portion for pressing a binding object and a pair of inserting portions extending from opposite ends of the pressing portion and being inserted into the binding object, comprising: an enclosing portion that encloses a plurality of block staples so as to be overlaid, each of the block staples having a plurality of the staples which are connected so that they can be separated; a clinch portion that bends the inserting portions of a staple; a projecting portion which projects the staple from the block staples enclosed in the enclosing portion, allows the inserting portions to be inserted through the binding object, bends the inserting portions in cooperation with the clinch portion, and binds the binding object; a moving unit that moves a bottom block of staples among the block staples overlaid in the enclosing portion toward a projecting position where the staple is projected; a feeding unit that feeds staples moved by the moving unit to the projecting position where the staple is projected, wherein the feeding unit comprises a moving member provided between the moving unit and the projecting position and that can move toward and away from the projecting position, with the moving member having a tapered portion that can be pressed by the projecting portion to move between a first position and a second position where the tapered portion moves from the first position by an amount corresponding to a thickness of one staple, and an engaging member provided on the moving member, with the engaging member able to engage with and be removed from between the staples of the block staples in accordance with the movement of the tapered portion from the first position to the second position, and be engaged between the staples of the block staples in accordance with the movement of the tapered portion from the second position to the first position; and an elastic member that biases the moving member toward the projecting position.
