<p><P>PROBLEM TO BE SOLVED: To provide a rotary punching apparatus capable of punching a sheet at a desired position and applying continuity of a shape. <P>SOLUTION: The rotary punching apparatus is constituted of an upper rotary plate 231 including a punching member 210 having a punching edge 212 with a pattern of a specific shape formed and an upper fixture 220 for elastically supporting the punching member and having a guide hole 221 of the same shape as that of the pattern formed, an upper plate 230 equipped with the upper rotary plate rotatable, a lower rotary plate 251 including a lower fixture 240 having a punching hole 241 with the same shape as that of the pattern formed, and a lower plate 250 equipped with the lower rotary plate rotatable. The upper plate and the lower plate include at least one magnet 233 on their opposite positions, and the upper rotary plate and the lower rotary plate include at least one magnet 235 on their opposite positions, thereby allowing their constant positions to be aligned by magnetic force. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
