  FIG. 13 is an explanatory diagram illustrating an effect example of the binding device according to the present embodiment. In the conventional binding device, the binding portion 40 that drives the punching blade 44 receives the force of the operation member 121 indicated by a one-dot chain line provided immediately above the punching blade 44. As a result, the force point P10 that receives the force of the operator and the action point P20 that exerts a force on the punching blade 44 from the operating member 121 substantially coincide. For this reason, the load applied to the operation member 121 when penetrating the sheet bundle 10 with the punching blade 44 and the load applied to the operation member 121 when the punching blade 44 comes out of the sheet bundle 10 together with the piece 2 are not reduced.

  On the other hand, in the binding device 1A, an action point P2 that exerts a force on the punching blade 44 from the handle portion 12 is provided between the force point P1 that receives the operator's force and the fulcrum P3, so that the force point P1 to the fulcrum P3. Is configured to be longer than the distance L2 from the action point P2 to the fulcrum P3.

  Accordingly, the operation load applied to the power point P1 of the handle portion 12 when the punching blade 44 penetrates the sheet bundle 10 and the force point P1 of the handle portion 12 applied to the punching blade 44 when the punching blade 44 is removed from the sheet bundle 10 together with the piece 2. The operation load is reduced compared to the case where the operation member 121 is directly above the punching blade 44. Moreover, the maximum height H of the handle part 12 can be made equal to the height of the conventional operation member 121, and the enlargement of the apparatus can be prevented.

  The operation load applied to the force point P1 of the handle portion 12 by the operation of the punching blade 44 penetrating the sheet bundle 10 is reduced, so that the punching blade 44 can be reliably penetrated through the sheet bundle 10. In addition, the operation load applied to the force point P1 of the handle portion 12 by the operation of the punching blade 44 withdrawing from the sheet bundle 10 together with the piece 2 is reduced, so that the piece 2 can be reliably inserted into the sheet bundle 10. Thereby, generation | occurrence | production of a binding defect can be suppressed.

  If the elastic member that biases the operation member in the returning direction is weak, the operation load can be reduced even in the conventional configuration, but the restoring force of the elastic member is weak in the operation of inserting the piece into the sheet bundle. In this case, the pieces cannot be surely inserted, and the possibility that a binding failure occurs increases. In the present embodiment, the operation load can be reduced without making the coil spring 45 that urges the handle portion 12 in the returning direction unnecessarily weak, and the operation of inserting the piece 2 into the sheet bundle 10 is reliable. The piece 2 can be inserted into
