Abstract
A cutting device includes a support base, a cutting blade, and a holding member. The cutting blade has first and second holes and a blade edge. The blade edge has a first convex portion and a second convex portion, provided at a position corresponding to the first and second holes, respectively. In a case where the cutting blade is arranged at a cutting position, a maximum value of a distance between the blade edge and the support base within a range between the first and second holes in a longitudinal direction of the cutting blade is smaller than a maximum value of a distance between the blade edge and the support base. The cutting blade is fixed to the holding member by a first hole coupling member, and the holding member holds the cutting blade so as to be movable to the cutting position and a spaced position.
Claims16
A cutting device comprising:
- a support base;
- a cutting blade configured to cut at least a part of a tape arranged between the cutting blade and the support base in a state where the cutting blade is arranged at a cutting position close to the support base, the cutting blade having:
- a first hole penetrating in a thickness direction of the cutting blade;
- a second hole arranged side by side with the first hole in a longitudinal direction of the cutting blade;
- and
- a blade edge extending in the longitudinal direction of the cutting blade, the blade edge having a first convex portion and a second convex portion, the first convex portion being provided at a position corresponding to the first hole in the longitudinal direction of the cutting blade and being convex in a first direction which is a direction from the first hole toward the blade edge, and the second convex portion being provided at a position corresponding to the second hole in the longitudinal direction of the cutting blade and being convex in the first direction, the first convex portion having a first arc shape including a first center and the second convex portion having a second arc shape including a second center spaced away from the first center, and
- a holding member to which the cutting blade is fixed by a first hole coupling member inserted in the first hole, the holding member holding the cutting blade so as to be movable to the cutting position and a spaced position at which the cutting blade is distant from the support base,
- wherein a first hole and the second hole are located within an intermediate range (R2) of the cutting blade in the longitudinal direction,
- wherein the blade edge includes a first portion that is outside of the intermediate range and spaced away from the support base by a first maximum distance in the state where the cutting blade is arranged at the cutting position, and
- wherein the blade edge includes a second portion that spans the intermediate range and is spaced away from the support base by a second maximum distance that is smaller than the first maximum distance in the state where the cutting blade is arranged at the cutting position.
