A pressure-sensitive transfer medium 1 according to the first embodiment shown in FIG. 1 cleans a pressure-sensitive transfer tape 3 having a pressure-sensitive transfer layer 3a on a substrate 3b, and a transfer head 7 at the end of the pressure-sensitive transfer tape 3. The adhesive tape 4 and the end tape 5 are sequentially formed and wound around the delivery core 6. The pressure-sensitive transfer medium 1 is mounted on the transfer tool 8 shown in FIG. 2, and the pressure-sensitive transfer layer 3a is transferred using the transfer head 7 of the transfer tool 8 while pressing the pressure-sensitive transfer tape 3 against the transfer target and sliding it. Used by.

  The transfer tool 8 rotates the transfer head 7, a shaft portion that can rotatably support the delivery core 6 and the winding core 2, and the delivery core 6 and the winding core 2 in conjunction with each other, such as a gear or an O-ring. It consists of an interlocking unit. When the pressure-sensitive transfer tape 3 is pressed against the transfer medium using the transfer head 7 and slid, the delivery core 6 feeds the substrate 3b provided with the pressure-sensitive transfer layer 3a by its rotation, and the take-up core 2 Takes up the substrate 3b after the pressure-sensitive transfer layer 3a has been transferred to the transfer medium by its rotation.

  The pressure-sensitive transfer layer 3a is, for example, a concealing layer and a pressure-sensitive adhesive layer in the case of a correction tape, and a pressure-sensitive adhesive layer in the case of the pressure-sensitive transfer adhesive tape 3. The correction tape is formed by coating and drying a coating material containing a white pigment such as titanium oxide and a binder resin on the base material 3b, and providing a concealing layer with a thickness of 3 to 40 microns so as to be releasable. The pressure-sensitive adhesive is applied and dried, and a pressure-sensitive adhesive layer is provided with a thickness of 0.3 to 10 microns. The pressure-sensitive transfer pressure-sensitive adhesive tape 3 is produced by, for example, applying and drying an acrylic pressure-sensitive pressure-sensitive adhesive on the substrate 3b, and providing a pressure-sensitive pressure-sensitive adhesive layer with a thickness of 1 to 50 microns so as to be releasable. . As the base material 3b, a plastic film such as polyethylene terephthalate having a thickness of 3 to 60 microns, or a long base material such as paper is used, and the pressure-sensitive transfer layer 3a is easy to release, and further, the base material 3b It is preferable that the both surfaces of the base material are release-treated so that the pressure-sensitive transfer layer 3a sticks to the back surface and so-called blocking does not occur. Although the correction tape and the pressure-sensitive transfer adhesive tape have been described, the present invention can also be applied to a colored tape in which the concealing layer of the correction tape is replaced with a colored layer using, for example, a fluorescent pigment.

As shown in FIG. 3, the pressure sensitive transfer tape 3 and the delivery core 6 are directly or directly moved by moving the substrate after the use of the pressure sensitive transfer tape 3 and bringing the transfer head 7 into contact with the adhesive layer 4 a of the adhesive tape 4. Compared with a conventional pressure-sensitive transfer medium connected via the end tape 5, wrinkles adhering to the transfer head 7 can be more reliably removed. That is, the pressure-sensitive transfer layer 3a such as the concealing layer and the pressure-sensitive adhesive layer is a layer having a high cohesive force and the adhesive force of the adhesive layer 4a, so that a part of the wrinkles comes into contact with the adhesive layer 4a. It is possible to take the wrinkles adhering to the transfer head 7 into the adhesive layer 4a. As the adhesive tape 4, a known adhesive tape can be used, for example, a structure in which an adhesive layer 4a is provided on a base material such as plastic or paper such as polyethylene terephthalate having a thickness of 10 to 30 microns.

  The end tape 5 formed between the adhesive tape 4 and the delivery core 6 is made of a base material such as plastic or paper such as polyethylene terephthalate having a thickness of 10 to 30 microns, for example. Furthermore, it is preferable that the side opposite to the surface on which the adhesive layer 4a is provided is subjected to a release treatment. This is to prevent the adhesive layer 4a from sticking to the end tape during winding and the adhesive layer 4a from running to the transfer head.

(Second form)
The 2nd form shown in FIG. 4 is the form which changed the adhesive tape 4 of the 1st form into the embossed tape 9. FIG. In the pressure-sensitive transfer medium 1 in the first form, the functional part for cleaning the transfer head 7 is the adhesive layer 4a, whereas in the second form, the textured surface 9a of the embossed tape 9 is shown in FIG. Compared with the conventional pressure-sensitive transfer medium in which the pressure-sensitive transfer tape 3 and the delivery core 6 are connected directly or via the end tape 5, the area in contact with the wrinkles attached to the transfer head 7 increases. Even if a part of the wrinkle is only in contact with the uneven surface 9a, the wrinkle adhering to the transfer head 7 can be taken into the uneven surface 9a, or the wrinkle can be scraped off from the uneven surface 9a, thereby removing the wrinkle more reliably. Can do. As the embossed tape 9, a known material can be used as long as one surface of a plastic substrate having a thickness of 10 to 50 microns is made uneven.
