Abstract

A binding machine includes a wire feeding unit configured to feed a wire, a curl guide configured to curl the wire fed by the wire feeding unit around an object to be bound, a binding unit including a twisting shaft provided to be rotatable around a predetermined axis, and a gripping part provided at one end side of the twisting shaft, wherein the gripping part is configured to grip the wire curled by the curl guide and the twisting shaft is configured to twist the gripped wire so as to bind the object, a binding machine main body having one end side at which the curl guide is arranged and configured to accommodate therein the wire feeding unit and the binding unit, and a setting unit provided at an opposite end side of the binding machine main body and configured to set a predetermined operation condition.

First claim

The invention claimed is:

1. A binding machine comprising:
a wire feeding unit configured to feed a wire;
a curl guide configured to curl the wire fed by the wire feeding unit around an object to be bound;
a binding unit including a twisting shaft which is rotatable around a predetermined axis, and a gripping part located at one end of the twisting shaft, wherein the gripping part is configured to grip the wire curled by the curl guide and the twisting shaft is configured to twist the gripped wire so as to bind the object;
a motor configured to operate the binding unit;
a binding machine main body having a front end side at which the object is bound, a rear end side at an opposite end to the front end side, and a top side which extends between the front end side and the rear end side, wherein a surface of the rear end side extends downwardly from the top side at a rear side of the binding machine main body, wherein the curl guide is located at the front end side, and wherein the binding unit and the motor are housed by the binding machine main body; and
a setting unit located on the surface of the rear end side of the binding machine main body and configured to set a predetermined operation condition of the motor,
wherein the rear end side of the binding machine main body includes a convex part provided along the setting unit and protruding in a rearward direction away from the front end side, and the convex part protrudes further in the rearward direction than the setting unit.

2. The binding machine according to claim 1 , further comprising:
a handle part extending downwardly from the binding machine main body at a lower portion of the binding machine main body.

3. The binding machine according to claim 1 ,
wherein the convex part is provided on at least one side of the setting unit.

4. The binding machine according to claim 1 , wherein the setting unit is surrounded by the convex part.

5. The binding machine according to claim 1 ,
wherein the rear end side of the binding machine main body is formed with a concave part, and
wherein the setting unit protrudes further rearward than the concave part.

6. The binding machine according to claim 1 ,
wherein the setting unit includes an indicator which indicates a setting value of the predetermined operation condition, and
wherein the indicator faces rearward.

7. The binding machine according to claim 1 , wherein the predetermined operation condition is a torsional torque of the wire.

8. A binding machine comprising:
a wire feeding unit configured to feed a wire;
a curl guide configured to curl the wire fed by the wire feeding unit around an object to be bound;
a binding unit including a twisting shaft which is rotatable around a predetermined axis, and a gripping part located at one end of the twisting shaft, wherein the gripping part is configured to grip the wire curled by the curl guide and the twisting shaft is configured to twist the gripped wire so as to bind the object;
a binding machine main body having a front end side at which the object is bound, a rear end side at an opposite end to the front end side, and a top side which extends between the front end side and the rear end side, wherein a surface of the rear end side extends downwardly from the top side at a rear side of the binding machine main body, wherein the curl guide is located at the front end side, and wherein the binding unit is housed by the binding machine main body; and
a power supply switch of the binding machine located on the surface of the rear end side of the binding machine main body,
wherein the rear end side of the binding machine main body includes a convex part provided along the power supply switch and protruding in a rearward direction away from the front end side, and the convex part protrudes further in the rearward direction than the power supply switch.

9. The binding machine according to claim 8 , further comprising:
a handle part extending downwardly from the binding machine main body at a lower portion of the binding machine main body.

10. The binding machine according to claim 8 ,
wherein the convex part is provided on at least one side of the power supply switch.

11. The binding machine according to claim 8 , wherein the power supply switch is surrounded by the convex part.

12. The binding machine according to claim 8 ,
wherein the rear end side of the binding machine main body is formed with a concave part, and
wherein the power supply switch protrudes further rearward than the concave part.

13. The binding machine according to claim 8 , wherein the rear end side of the binding machine main body includes an indicator which indicates a state of the power supply switch.

14. The binding machine according to claim 8 ,
wherein the power supply switch is manually operable in a forward direction, the forward direction being a direction extending from the rear end side to the curl guide.

15. The binding machine according to claim 1 ,
wherein the setting unit includes an electric indicator which indicates a state of the binding machine, and
wherein the electric indicator faces rearward.

16. The binding machine according to claim 1 ,
wherein the convex part extends in an upper-lower direction.

17. The binding machine according to claim 1 ,
wherein the convex part includes a plurality of portions which protrude different amounts in the rearward direction.
