Abstract

A cutter device, comprising: a first blade including a first cutting edge extending in a first direction; a second blade including a second cutting edge extending in a second direction; and a guide portion provided at a position anterior to the second blade in the second direction, wherein the second blade moves in the second direction to cut a recording medium while leaving a part thereof uncut, and when the second blade is located posterior, in the second direction, to a position where the second blade cuts the recording medium, at least a part of the guide portion is located to protrude farther in the first direction than the first cutting edge, or located at a same position as the first cutting edge.

First claim

What is claimed is:

1. A cutter device, comprising:
a first blade including a first cutting edge extending in a first direction;
a second blade including a second cutting edge extending in a second direction; and
a guide portion provided at a position anterior to the second blade in the second direction, wherein
the second blade moves in the second direction to cut a recording medium while leaving a part thereof uncut,
when the second blade is located posterior, in the second direction, to a position where the second blade cuts the recording medium, at least a part of the guide portion is located to protrude farther in the first direction than the first cutting edge, or located at a same position as the first cutting edge, and
the first blade is provided in a first structure, the second blade is provided in a second structure that is different from the first structure, and a posture of the second structure is changeable with respect to the first structure.

2. The cutter device according to claim 1 , wherein the second blade and the guide portion are formed as an integral member.

3. The cutter device according to claim 2 , wherein the second blade and the guide portion form a hole through which the recording medium passes.

4. The cutter device according to claim 1 , wherein
the second blade and the guide portion are members separate from each other, and
during movement of the second blade in the second direction and during movement of the second blade in the first direction, the guide portion is coupled to the second blade and moves together with the second blade.

5. The cutter device according to claim 1 , wherein the first blade and the guide portion are provided in the first structure.

6. A printer, comprising:
a printing head configured to perform printing on the recording medium; and
the cutter device according to claim 1 .

7. The cutter device according to claim 1 , wherein the second blade and the guide portion are provided in the second structure.
