    • A cylindrical punch member equipped at the leading end thereof with a hole-punching blade is movably supported on a base frame in a hole-punching direction. A drive means is equipped that applies thrusting force to the punch member; a cam follower member disposed between the base frame and punch member engages a cam means disposed at either the base frame or punch member. An oblique cam surface inclined at a predetermined angle with regard to a hole-punching direction is equipped in cam means to give rotational drive force around an axis of rotation to the punch member that is moved in the hole-punching direction by the drive means. This configuration causes each of a plurality of cylindrical punch members to rotate around their axes of rotation when moved in a hole-punching direction by drive means thereby punching a hole in a sheet with a reduced shear force; the centrifugal force of that punch member rotation causing paper cutting debris to be scattered evenly under the punch member.
    • 在其前端配备有冲孔刀片的圆柱形冲头构件以穿孔方向可移动地支撑在基架上。 驱动装置配备有向冲头构件施加推力; 设置在基架和冲头构件之间的凸轮从动构件与设置在基架或冲压构件上的凸轮装置接合。 相对于打孔方向以预定角度倾斜的倾斜凸轮表面装配有凸轮装置,以通过驱动装置向穿孔方向移动的冲头构件提供围绕旋转轴线的旋转驱动力。 这种构造使得当多个圆柱形冲头构件中的每一个在通过驱动装置沿打孔方向移动时绕其旋转轴线旋转,从而以减小的剪切力冲压在片材中的孔; 该冲头构件旋转的离心力使得切纸屑在打孔构件下均匀地分散。
