## 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;
a first abutment portion which is provided between the wire feeding portion and the cutting portion and on a first side of a feeding path of the wire and capable of abutting on the wire from the first side; and
a guide portion which is provided on a downstream side of the cutting portion and on a second side opposite to the first side with respect to the feeding path of the wire, includes a second abutment portion capable of abutting on the wire from the second side, and regulates an advancing direction of the wire and causes the wire to curl by making the second abutment portion abut on the wire in a state where the wire abuts on the first abutment portion, wherein
the cutting portion includes:
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 is formed and which slides on an outer peripheral surface of the fixed blade and cuts the wire, the second wire passage being configured by an opening through which the wire passes,
the movable blade configured to move 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,
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, the guiding portion including a recess configured such that a dimension, in the moving direction of the movable blade, of a downstream side end of the opening, in the feeding direction of the wire, is greater than a dimension of an upstream side end of the opening, in the feeding direction of the wire, the recess being configured to hold and contact the wire, and
the guiding portion is located on the second side and is configured to protrude 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.

### Claim 2 (depends on 1)

A binding machine according to claim 1, wherein
in the second wire passage, the dimension of the opening in the movement direction of the movable blade expands from the upstream side end to the downstream side end,
the downstream side end of the opening is configured to face the guide portion, and
the upstream side end of the opening is configured to face the fixed blade.

### Claim 3

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 the 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 configured to move 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, the movable blade having a protruding portion protruding in a direction of the guide portion,
the cutting portion suppresses a change in behavior of the wire between the protruding portion and the guide portion when the movable blade moves to the movement finish position,
the second wire passage further includes a recess adjacent to the protruding portion and that is configured to hold and contact the wire.
