Abstract

A cutting device of a scissors type includes a fixed edge, a movable edge, and a support shaft configured to support the fixed edge and the movable edge to be capable of mutually rotating. A movable edge main body of the movable edge including a cut-off edge is cut into, centering on the support shaft, a fixed edge main body of the fixed edge including a cut-off edge. The cutting device includes a receiving member provided along at least an edge front side of the fixed edge main body and an edge front side of the movable edge main body and a pressing section configured to press at least one of the fixed edge main body and the movable edge main body to tilt in the opposite direction of the receiving member to be received by the receiving member.

First claim

What is claimed is:

1. A cutting device of a scissors type including a fixed edge, a movable edge, and a support shaft configured to support the fixed edge and the movable edge such that the movable edge is configured to rotate with respect to the fixed edge,
a movable edge main body of the movable edge including a cut-off edge being cut into, centering on the support shaft, a fixed edge main body of the fixed edge including a cut-off edge,
the cutting device comprising:
a receiving member provided along at least an edge front side of the fixed edge main body and an edge front side of the movable edge main body;
a pressing section configured to press at least one of the fixed edge main body and the movable edge main body to tilt in an opposite direction of the receiving member to be received by the receiving member; and
a contact point section interposed between an extended upper part present on extension of an edge tip of the movable edge across the support shaft and an extended overlapping part of the fixed edge overlapping the extended upper part in a shaft peripheral edge portion on an edge back side of the movable edge and configured to press the movable edge main body to tilt to a fixed edge side with the support shaft as a fulcrum.

2. The cutting device according to claim 1 , wherein the contact point section is provided in the fixed edge and formed in an arcuate shape centering on the support shaft.

3. The cutting device according to claim 2 , wherein the contact point section has an inclined surface inclining upward in a turning direction of the cutting-in movable edge.

4. A printing apparatus comprising:
a printing section configured to perform printing on a printing tape; and
the cutting device according to claim 3 configured to cut off a printed portion of the printing tape.

5. A printing apparatus comprising:
a printing section configured to perform printing on a printing tape; and
the cutting device according to claim 2 configured to cut off a printed portion of the printing tape.

6. A printing apparatus comprising:
a printing section configured to perform printing on a printing tape; and
the cutting device according to claim 1 configured to cut off a printed portion of the printing tape.

7. A printing apparatus comprising:
a printing section configured to perform printing on a printing tape; and
a cutting device configured to cut off a printed portion of the printing tape, the cutting device being of a scissors type including a fixed edge, a movable edge, and a support shaft configured to support the fixed edge and the movable edge such that the movable edge is configured to rotate with respect to the fixed edge, a movable edge main body of the movable edge including a cut-off edge being cut into, centering on the support shaft, a fixed edge main body of the fixed edge including a cut-off edge, the cutting device comprising:
a receiving member provided along at least an edge front side of the fixed edge main body and an edge front side of the movable edge main body;
a pressing section configured to press at least one of the fixed edge main body and the movable edge main body to tilt in an opposite direction of the receiving member to be received by the receiving member; and
a contact point section interposed between an extended upper part present on extension of an edge tip of the movable edge across the support shaft and an extended overlapping part of the fixed edge overlapping the extended upper part in a shaft peripheral edge portion on an edge back side of the movable edge and configured to press the movable edge main body to tilt to a fixed edge side with the support shaft as a fulcrum.
