## Abstract

A binding machine comprises a cutting portion which cuts the wire, a fixed blade in which a first wire passage through which the wire passes is formed; and a movable blade in which a second wire passage through which the wire passes is formed. The movable blade includes a blade portion provided on one side of the second wire passage and a passage forming member provided on the other side of the second wire passage, the second wire passage includes a guiding portion for guiding the wire after cutting in a movement when the movable blade moves from the movement finish position to the standby position, and the guiding portion is protrudes in a direction of the guide portion and blocks a portion between the movable blade and the guide portion in a non-wire-passing-through manner when the movable blade moves to the standby position.

## Claims

### Claim 1

A binding machine, comprising:
a wire feeding portion which feeds a wire;
a cutting portion which is provided on a downstream side of the wire feeding portion along a feeding direction of the wire fed by the wire feeding portion and cuts the wire; and
a guide portion which is provided on a downstream side of the cutting portion along a feeding direction of the wire and causes the wire to curl by regulating an advancing direction of the wire, wherein
the cutting portion includes:
a fixed blade in which a first wire passage through which the wire passes is formed;
a movable blade in which a second wire passage through which the wire passes is formed and which slides on an outer peripheral surface of the fixed blade and cuts the wire; and
a driving member which is connected to the movable blade and drives the movable blade,
the movable blade is capable of moving between a standby position where the first wire passage and the second wire passage communicate with each other and a movement finish position where the first wire passage and the second wire passage do not communicate with each other by sliding on the outer peripheral surface of the fixed blade, and
the guide portion includes a wire retracting portion at an end portion facing the movable blade, the wire retracting portion being constituted by a surface retracted in a direction where a distance from the movable blade increases.

### Claim 2 (depends on 1)

The binding machine according to claim 1, wherein
in the cutting portion, an opening which is equal to or larger than a diameter of the wire is formed between the movable blade and the driving member when the movable blade moves to the standby position.

### Claim 3 (depends on 1)

The binding machine according to claim 1, wherein
the cutting portion is configured such that a distance between the movable blade and the driving member is less than the diameter of the wire when the movable blade moves to the standby position.
