Claims

[Claims for Utility Model Registration] (1) A supply roll that supplies a wound ink sheet and a take-up roll that winds up the ink sheet are rotatably supported by a support at a fixed interval, and An ink sheet cassette that can be attached and detached for use includes a first disc-shaped member, a second disc-shaped member, a first claw member, and a second claw member, and the first disc-shaped member is connected to the supply roll. The second disc-shaped member is fixed coaxially to the end of the take-up roll and has a plurality of first recesses on the outer periphery, and the second disc-shaped member is fixed to the end coaxially with the take-up roll and has a second recess on the outer periphery. , the first claw member is rotatably supported by the support body, one end side is biased to enter the first recess, and when the first claw member is mounted on the printer, the other end side is pushed and the one end side is pushed into the first recess. The second claw member is rotated so as to be removed from the first recess, the second claw member is rotatably supported by the support, and one end side is urged to enter the second recess, and when the second claw member is attached to the printer. The other end side is pushed so that the one end side is rotated so as to be removed from the second recess, and the first recess is connected to the first claw member when the supply roll rotates in the winding direction of the ink sheet. The first claw member has a shape that does not apply a force in a direction to remove the ink sheet from the recess, and applies a force to the first claw member in a direction to remove the ink sheet from the first recess when the supply roll rotates in the rewinding direction of the ink sheet; An ink sheet cassette characterized in that the second recess has a shape that does not apply a force to the second claw member in a direction to remove it from the second recess when the take-up roll rotates in the rewinding direction of the ink sheet. . (2) The ink sheet cassette according to claim 1, wherein the second recess is provided at only one location on the circumference of the second disc-shaped member. (3) The one end side of the second claw member is deformed within the second recess when a tension above a certain level is generated in the ink sheet, and the second claw member deforms in the second recess before the ink sheet is cut. The ink sheet cassette according to claim 1 or 2, wherein the ink sheet cassette is detachable from the second recess.
