テープを損傷するのも防愚ことができる。As described above, according to the tape feed roller according to the present invention, a plurality of concave air vent grooves which are parallel to the tape feed direction and are continuous over the entire circumference of the roller surface are made parallel. In this case, the air flow which flows in the circumferential direction of the roller from the air vent groove parallel to the tape feeding direction is generated, so that not only the tape feeding direction can be regulated, but also the roller surface is traversed obliquely linearly across the roller surface. The air flows in the circumferential direction of the roller by providing a plurality of concave air bleed grooves intersecting with the air bleed grooves extending over the entire circumference in the circumferential direction and passing from one roller side surface to the other roller side surface at regular intervals. The air flow merges with the air vent groove obliquely crossing the roller surface, and the air flow that escapes from the air vent groove to the side of the roller is generated. Regardless of the surface position, the air embraced between the roller surface and the tape surface can smoothly escape outward from the roller surface, allowing the tape surface to come into close contact with the roller surface and allowing the tape to contact the roller surface for a long time. While being able to send well,
Damage to the tape can be silly.
