Abstract

A cutting device, having a supporting base, a cutter section, a protrusive part, is provided. The supporting base has a first area, in which a tape is placeable, and a second area on a surface thereof The surface is formed of a resin coating layer in the first area alone between the first area and the second area. The cutter section has a blade and is movable to approach and separate from the surface. The protrusive part protrudes from the cutter section in a direction, toward which an edge of the blade points. When the cutter section approaches the surface of the supporting base, with the protrusive part contacting the surface of the supporting base in the second area, the blade cuts the tape located between the surface of the supporting base in the first area and the blade partly in a direction of thickness of the tape.

First claim

What is claimed is:

1 . A cutting device, comprising:
a supporting base having a first area, in which a tape is placeable, and a second area different from the first area, on a surface thereof, the surface being formed of a coating layer made of a resin in the first area alone between the first area and the second area; a cutter section comprising a blade, the cutter section being movable to approach and separate from the surface of the supporting base; and a protrusive part protruding from the cutter section in a direction, toward which an edge of the blade points, the protrusive part being configured to contact the surface of the supporting base in the second area when the cutter section approaches the surface of the supporting base, wherein the cutter section is configured such that, when the cutter section approaches the surface of the supporting base, with the protrusive part contacting the surface of the supporting base in the second area, the blade cuts the tape located between the surface of the supporting base in the first area and the blade partly in a direction of thickness of the tape.

2 . The cutting device according to claim 1 , wherein the coating layer forms concavities and convexities on the surface.

3 . The cutting device according to claim 1 ,
wherein a thickness of the coating layer is smaller than a distance between the edge and a protrusive end of the protrusive part in the direction, toward which the edge of the blade points.

4 . The cutting device according to claim 1 ,
wherein the supporting base has a stainless plane, the stainless plane having the coating layer thereon in the first area and being exposed in the second area, and wherein the surface of the supporting base is formed of the stainless plane in the second area.

5 . A cutting device, comprising:
a supporting base having a first area, in which a tape is placeable, and a second area different from the first area, on a surface thereof, the surface being formed of a coating layer in the first area, a hardness of the surface of the supporting base in the second area being greater than a hardness of the surface of the supporting base in the first area; a cutter section comprising a blade, the cutter section being movable to approach and separate from the surface of the supporting base; and a protrusive part protruding from the cutter section in a direction, toward which an edge of the blade points, the protrusive part being configured to contact the surface of the supporting base in the second area when the cutter section approaches the surface of the supporting base, wherein the cutter section is configured such that, when the cutter section approaches the surface of the supporting base, with the protrusive part contacting the surface of the supporting base in the second area, the blade cuts the tape located between the surface of the supporting base in the first area and the blade partly in a direction of thickness of the tape.

6 . The cutting device according to claim 5 , wherein the coating layer forms concavities and convexities on the surface.

7 . The cutting device according to claim 5 ,
wherein a thickness of the coating layer is smaller than a distance between the edge and a protrusive end of the protrusive part in the direction, toward which the edge of the blade points.

8 . The cutting device according to claim 5 ,
wherein the supporting base has a stainless plane, the stainless plane having the coating layer thereon in the first area and being exposed in the second area, and wherein the surface of the supporting base is formed of the stainless plane in the second area.

9 . A printer, comprising:
a printing device configured to print an image on a tape; a conveyer configured to convey the tape with the image printed thereon; and a cutting device, comprising:
a supporting base having a first area, in which the tape conveyed by the conveyer is placeable, and a second area different from the first area, on a surface thereof, the surface being formed of a coating layer made of a resin in the first area alone between the first area and the second area;
a cutter section comprising a blade, the cutter section being movable to approach and separate from the surface of the supporting base; and
a protrusive part protruding from the cutter section in a direction, toward which an edge of the blade points, the protrusive part being configured to contact the surface of the supporting base in the second area when the cutter section approaches the surface of the supporting base,
wherein the cutter section is configured such that, when the cutter section approaches the surface of the supporting base, with the protrusive part contacting the surface of the supporting base in the second area, the blade cuts the tape conveyed by the conveyer to a position in the first area of the supporting base between the surface and the blade partly in a direction of thickness of the tape.

10 . A printer, comprising:
a printing device configured to print an image on a tape; a conveyer configured to convey the tape with the image printed thereon; and a cutting device, comprising:
a supporting base having a first area, in which the tape conveyed by the conveyer is placeable, and a second area different from the first area, on a surface thereof, the surface being formed of a coating layer in the first area, a hardness of the surface of the supporting base in the second area being greater than a hardness of the surface of the supporting base in the first area;
a cutter section comprising a blade, the cutter section being movable to approach and separate from the surface of the supporting base; and
a protrusive part protruding from the cutter section in a direction, toward which an edge of the blade points, the protrusive part being configured to contact the surface of the supporting base in the second area when the cutter section approaches the surface of the supporting base,
wherein the cutter section is configured such that, when the cutter section approaches the surface of the supporting base, with the protrusive part contacting the surface of the supporting base in the second area, the blade cuts the tape conveyed by the conveyer to a position in the first area of the supporting base between the surface and the blade partly in a direction of thickness of the tape.
