portion having a tapered surface contacting with at least a part of the abutment. ### Claim 5 (depends on 3) The apparatus according to claim 3, wherein the receiving portion includes a plurality of elastic portions which is elastically deformable and has the tapered surfaces and a blocking portion formed on a part thereof except for the tapered surfaces and controlling a position of the casing in a pressing direction of the pressing unit against the cutter cartridge, and when the cutter cartridge is attached to the cartridge holder and the pressing unit is switched to the fixing position, the casing abuts against the blocking portion thereby to be prevented from movement in the pressing direction of the pressing unit and is fixed in a state where the abutment abuts against the tapered surfaces of the elastic portions to elastically deform the elastic portions. ### Claim 6 (depends on 4) The apparatus according to claim 4, wherein the receiving portion includes a plurality of elastic portions which is elastically deformable and has the tapered surfaces and a blocking portion formed on a part thereof except for the tapered surfaces and controlling a position of the casing in a pressing direction of the pressing unit against the cutter cartridge, and when the cutter cartridge is attached to the cartridge holder and the pressing unit is switched to the fixing position, the casing abuts against the blocking portion thereby to be prevented from movement in the pressing direction of the pressing unit and is fixed in a state where the abutment abuts against the tapered surfaces of the elastic portions to elastically deform the elastic portions. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein the casing includes a support provided in the casing to support a base of the cutter so that the base of the cutter is rotatable about the central axis and is immovable in a direction of the central axis, and a cap surrounding the blade, and wherein the abutment is formed over an entire circumference of the cap. ### Claim 8 (depends on 2) The apparatus according to claim 2, wherein the casing includes a support provided in the casing to support a
