An impelling blade guide is inserted into a space provided for inserting a blade unit in order to create a simple structure for the removal of staples which have become jammed in the staple ejecting mouth during empty operation. A notched section is formed in proximity to the staple ejecting mouth of the frame. During normal operation, the impelling blade guide can be easily raised since an indentation formed on the notched section and a projection formed on the impelling blade guide are fixed. When a staple is jammed in the staple ejecting mouth, the impelling blade guide is pulled up and the projection separates from the indentation. Thus the rear surface side of the staple ejecting mouth is opened. In such a way, jammed staples can be easily removed from the staple ejecting mouth.
