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.

Dependent claims

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.
