<p>PROBLEM TO BE SOLVED: To reduce positional deviation of a blade tip part due to replacement of a plate-like cutter.SOLUTION: A cutter cartridge includes a chuck shaft, a sleeve, connection means, a chuck, and conversion means. The connection means connects the sleeve to the chuck shaft so that the sleeve is movable in the axial direction of the chuck shaft. The chuck is configured by a combination of a first chuck member having a first contact part and a second chuck member having a second contact part. The first contact part is brought into contact with a plane part and a side edge part on one side of a cutter. The second contact part is brought into contact with a plane part and a side edge part on the other side of the cutter. The chuck holds the cutter between the first contact part and the second contact part while exposing the cutter from an end part on a side opposite to the chuck shaft, and makes the cutter face the outside of the sleeve from an end part on a side opposite to the chuck shaft of the sleeve. The conversion means converts movement in a direction where the sleeve and the chuck shaft approach each other into movement in the center direction of a shaft part to transmit the converted movement to the first chuck member and the second chuck member.</p> |
