It is movable in the A1 direction and in the arrow A2 direction along the movement of the thermal head 123 away from the platen roller 122.

Further, the second slider 131b is supported so as to be slidably movable along the moving direction of the first slider 131a, and is separated from the platen roller 122 in the arrow A1 direction along the movement of the thermal head 123 approaching the platen roller 122. It can move in the direction of arrow A2 along the movement of the thermal head 123.

The head slider 131 is pressed by 131c in a direction in which the distance between the first cam pressing portion 131a2 of the first slider 131a and the abutting protrusion 131b1 of the second slider 131b is widened, and the abutting collision of the second slider 131b. The portion 131b1 is pressed against the abutting portion 131a3 of the first slider 131a, and the positions of the first slider 131a and the second slider 131b are restricted.

The head slider 131 is a spring in which the head pressing portion 131a1 of the first slider 131a is arranged on the back surface side of the thermal head 123 facing the frame portion 123a and is composed of a tension coil spring (not shown) of the first slider 131a. The head pressing portion 131a1 and the thermal head 123 are connected.

As a result, when the first slider 131a moves in the direction of the arrow A1 that brings the thermal head 123 closer to the platen roller 122, the thermal head 123 is pushed in the direction of the platen roller 122 by the head pressing portion 131a1, and the thermal head 123 is pushed in the direction of the platen roller 122. It is pressed by the platen roller 122 by the rotational operation with the fulcrum as a fulcrum.

Further, when the first slider 131a moves in the direction of the arrow A2 that separates the thermal head 123 from the platen roller 122, the thermal head 123 is pulled in the direction away from the platen roller 122 by the head pressing portion 131a1 via the spring, and the thermal head 123 is pulled away from the platen roller 122. The head 123 retracts from the platen roller 122 by a rotational operation with the shaft 123b as a fulcrum.

The head moving cam 133 is an example of a transmission means, and is rotatably supported by a side plate (not shown) attached to the lower plate 124 via a shaft 133a, and is a first cam pressing portion of the first slider 131a.

The operation of pressing the thermal head 123 against the platen roller 122 and the operation of retracting the thermal head 123 from the platen roller 122 are performed.

In the head moving mechanism 130, when the second cam pressing portion 131b2 of the second slider 131b is pressed by the head moving cam 133, the head slider 131 moves in the arrow A1 direction in which the thermal head 123 approaches the platen roller 122. As shown in FIG. 4A, the thermal head 123 moves to the pressing position.

That is, in the head slider 131, when the second cam pressing portion 131b2 of the second slider 131b is pressed by the head moving cam 133, the first slider 131a is pressed by the cam surface 133c, and the second slider 131b and the second slider 131b are pressed. In conjunction with this, the first slider 131a moves in the direction of arrow A1.

As a result, the thermal head 123 is pushed in the direction of the platen roller 122 by the head pressing portion 131a1 of the first slider 131a, and the printing medium P such as a tube and the ink ribbon are sandwiched between the thermal head 123 and the platen roller 122.

Then, when the second cam pressing portion 131b2 of the second slider 131b is pressed while the printing medium P such as a tube is sandwiched between the thermal head 123 and the platen roller 122, the first slider 131a is pressed. On the other hand, the second slider 131b moves in the direction of the arrow A1 to compress the 131c, and the thermal head 123 sandwiching the print medium P with the platen roller 122 is pressed against the platen roller 122 by the force of the cam surface 131c.
