Abstract

A cutter device including a transport unit for transporting a medium, a round blade configured to move, while rotating, in a width direction intersecting a transport direction in which the medium is transported, a fixed blade provided along the width direction, and a controller configured to control driving of the transport unit and a movement in the width direction of the round blade, in which the controller is configured, when the medium is cut by causing the round blade to move to a first direction of the width direction, to cause the round blade to move to a second direction being a direction opposite to the first direction while causing the round blade to rotate without causing the medium to move in the transport direction.

First claim

What is claimed is:

1. A cutter device comprising:
a transport unit for transporting a medium;
a round blade configured to move, while rotating, in a width direction intersecting a transport direction in which the medium is transported;
a fixed blade provided along the width direction; and
a controller configured to control driving of the transport unit and a movement in the width direction of the round blade, wherein
the controller is configured to cause the round blade to cut the medium by moving the round blade in a first direction of the width direction and subsequently, while causing the round blade to rotate, moving the round blade in a second direction of the width direction that is opposite of the first direction, wherein the medium to does not move in the transport direction before the round blade moves in the second direction, and
wherein when moving in the second direction, the round blade is configured while rotating to rub against a face of the medium where the medium was previously cut while the round blade moved in the first direction, the rubbing causing the medium to be lifted up such that an entirety of the round blade rubs against the face of the medium.

2. The cutter device according to claim 1 , comprising:
a rack provided along the width direction; and
a carriage including a pinion that engages with the rack and a gear that transmits a rotation of the pinion to the round blade and holding the round blade, wherein
the round blade is configured to rotate in accordance with a movement of the carriage in the width direction.

3. The cutter device according to claim 1 , wherein the round blade rotates in a first rotational direction while cutting the medium when the round blade moves in as the first direction.

4. The cutter device according to claim 3 , wherein a rotational speed at which the round blade rotates in the first rotational direction while cutting the medium is set greater than a speed at which the round blade moves in the first direction.

5. The cutter device according to claim 3 , wherein when the round blade moves in the second direction, the round blade rotates in a second rotational direction that is opposite of the first rotational direction.

6. The cutter device according to claim 1 , wherein the round blade has a surface coated with a coating for suppressing adhesion of an adhesive.

7. The cutter device according to claim 1 , wherein the round blade has a surface subjected to processing for suppressing adhesion of an adhesive.

8. A printing apparatus comprising:
a transport unit for transporting a medium;
a printing unit configured to perform printing on the medium;
a round blade configured to move, while rotating, in a width direction intersecting a transport direction in which the medium is transported;
a fixed blade provided along the width direction; and
a controller configured to control driving of the transport unit and the printing unit, and a movement in the width direction of the round blade, wherein
the controller is configured to cause the round blade to cut the medium by moving the round blade in a first direction of the width direction and subsequently, while causing the round blade to rotate, moving the round blade in a second direction of the width direction that is opposite of the first direction, wherein the medium does not move in the transport direction before the round blade moves in the second direction, and
wherein when moving in the second direction, the round blade is configured while rotating to rub against a face of the medium where the medium was previously cut while the round blade moved in the first direction, the rubbing causing the medium to be lifted up such that an entirety of the round blade rubs against the face of the medium.
