The meandering of the print-receiving tape 2 can be prevented. In addition, since the convex portion 50A having a predetermined height is formed in the circumferential direction substantially at the center portion of the outer circumferential surface of the guide member 50 in the axial direction, it is possible to prevent the ink ribbon 9 from meandering, and to prevent the ink ribbon 9 from meandering. Wrinkles can be prevented from occurring. Further, the guide member 43 is provided with the double-sided adhesive tape 1.
Since the guide roller 44 having an outer peripheral surface having releasability is rotatably loosely fitted to the second adhesive surface, the guide roller 44 in contact with the double-sided adhesive tape 12 is used for traveling of the double-sided adhesive tape 12. Rotate with it, double-sided adhesive tape 1
2 can be easily peeled off, and the double-sided adhesive tape can be smoothly fed. In addition, the guide rollers 44 are provided with the projections 4 at predetermined intervals in the axial direction of the outer peripheral surface.
Since 4A is formed in the circumferential direction, it is possible to improve the releasability from the double-sided pressure-sensitive adhesive tape 12, and also possible to more smoothly feed the double-sided pressure-sensitive adhesive tape 12.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention.
