<P>PROBLEM TO BE SOLVED: To solve such a problem that a degree of freedom of design is restricted since large stress acts on a boundary between a member on a side supporting an anvil and a member on a side supporting a punching blade and a cutting blade by receiving an excessive operation force when the anvil perforates a paper sheet. <P>SOLUTION: In a binding machine 1, paper sheets P are disposed into a paper insertion clearance sk formed between the anvil 5, and a punching blade 42 and the cutting blade 43. The punching blade 42 and the cutting blade 43 are moved in an anvil 5 direction to penetrate the paper sheets P. By the cooperation of the punching blade 42, the cutting blade 43 and the anvil, a punched hole P1, a cut hole P2, and a raised piece P5 are formed to bind the paper sheets P. The anvil 5 has a reinforcement part 52 with a shape surrounding at least a back region sk1 of the clearance sk, and at least a part of the reinforcement part 52 is engaged with a member on a side supporting the punching blade 42 and the cutting blade 43. <P>COPYRIGHT: (C)2013,JPO&INPIT |
