Abstract
An inventive punching unit is provided with punches (2) whose blade (2a) is cut away in a shape of V at a shearing angle (a) whose apex (b) is set at a position offset from an axial center line (O-O) of the punch (2) by a predetermined distance (c). Because the lengths of left and right edges (P3 and P4) of the blade (2a) are different and these edges (P3 and P4) contact with a sheet at staggered timing, a peak value of punching force of the punch (2) may be lowered. Thus, the peak values of the punch are lowered and hence a driving force is lowered.
