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. ## Claims ### Claim 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, the movable edge including a movable edge main body including a cut-off edge and an actuation lever section ranging to the movable edge main body and bending and extending to the fixed edge side in a portion of the support shaft, wherein at least one of an edge part of the actuation lever section separated from the support shaft in an extending direction of the fixed edge and an overlapping part of the fixed edge overlapping the edge part is formed in a concave shape to form a gap between the edge part and the overlapping part, and the gap between the edge part and the overlapping part extends to an outer periphery of the fixed edge in a direction that is perpendicular to the extending direction of the fixed edge. ### Claim 2 (depends on 1) The cutting device according to claim 1, wherein in an edge back of the fixed edge, a splitting section is recessed along an edge tip of the fixed edge, the overlapping part is formed in the concave shape, and the overlapping part is configured by a recessed section ranging to the splitting section. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 2) The cutting device according to claim 2, comprising a contact point section interposed between an extended upper part present on extension of the 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 the fixed edge side with the support shaft as a fulcrum. ### Claim 5 (depends on 4) The cutting device according to claim 4, wherein the contact point section is provided in the fixed edge and formed in an arcuate shape centering on the support shaft. ### Claim 6 (depends on 5) The cutting device according to claim 5, wherein the contact point section has an inclined surface inclining upward in a turning direction of the cutting-in movable edge. tape. ### Claim 7 (depends on 6) A printing apparatus comprising: a printing section configured to perform printing on a printing tape; and the cutting device according to claim 6 configured to cut off a printed portion of the printing tape. ### Claim 8 (depends on 4) A printing apparatus comprising: a printing section configured to perform printing on a printing tape; and the cutting device according to claim 4 configured to cut off a printed portion of the printing tape. ### Claim 9 (depends on 5) A printing apparatus comprising: a printing section configured to perform printing on a printing tape; and the cutting device according to claim 5 configured to cut off a printed portion of the printing tape. ### Claim 10 (depends on 1) 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.
