In this half-cut device 18, the movable blade 18b and the stopper 60 are fixed to the movable arm 70, and the movable blade 18b and the stopper 60 are connected to the arm portion 73 of the movable arm 70 with respect to the movable arm 70 as described above. There is no sliding movement in the longitudinal direction.

  In this way, by forming the half-cut device 18, as shown in FIG. 9A, the upper portion of the shaft hole 78 of the movable arm 70 and the upper portion of the rotating shaft 71 are engaged with each other so that they are arranged in the initial state. As shown in FIG. 9B, the movable arm 70 is rotated about the rotation shaft 71 until the fulcrum portion 77 comes into contact with the plate-like support member 100 disposed on the housing 2, As shown in FIG. 9C, when the movable arm 70 is further rotated with the contact surface between the fulcrum portion 77 and the support member 100 as a fulcrum, the movable blade 18b is moved along the shaft hole 78 together with the movable arm 70. The printing tape 31 can be slid upward in the width direction.

  Specifically, as shown in FIG. 9B, the fulcrum portion 77 is formed so as to be in contact with the support member 100 on the housing 2 side immediately before the movable blade 18b is in contact with the printing tape 31, Further, since the fulcrum part 77 is formed in a semi-cylindrical shape, the fulcrum, which is a contact point between the fulcrum part 77 and the support member 100, slightly slides toward the rotary shaft 71 as the movable arm 70 rotates. The movable blade 18b slides and moves along the contact surface between the rotating shaft 71 and the shaft hole 78 (that is, upward parallel to the blade line) while rotating together with the movable arm 70.

  Thus, as described above, the movable blade 18b can be rotated and slid in the blade line extending direction to pull out the printing tape 31, so that the printing tape 31 can be easily obtained without requiring a large load. Can be partially cut. The fulcrum portion 77 can be formed on the support member 100 on the side of the housing 2 without being formed on the movable arm 70 to perform the same operation. Further, with respect to the rotating shaft 71 and the shaft hole 78, the rotating shaft 71 may be fixed to the movable arm 70, and the shaft hole 78 may be formed in the base 81 of the receiving base 18a. Furthermore, the movable blade 18b, the stopper 60, and the movable arm 70 may be integrally formed.

  The present invention is not limited to the above-described embodiments, and can be freely changed and improved without departing from the gist of the invention.
