<p>PURPOSE:To easily perform a jam processing in a comfortable posture by uniting a component member for punching excepting an extrusion means and fitting it drawably to the external part to a supporting frame body. CONSTITUTION:When a unit U is pulled out to the external part with its turning centering around a shaft 32, the upper part of the unit U is released. In this case, an extruding means 30 remains as it is left to a support frame body side. A punching edge 26 of the pulled out unit U side becomes in a free state. A jam processing can therefore be performed easily in a comfortable posture.</p> |
