<p>PROBLEM TO BE SOLVED: To stably guide a tape even at a high tape speed. SOLUTION: A tape guide (38) is provided with a hub (42) having a surface, over which the tape passes, and a pair of flanges 40 parallel spaced apart from the hub (42) while extending out from the hub and a plurality of grooves (50) on the surface of the hub (42). Each of grooves (50) has the same width, the groove (50) is mutually separated just for a fixed distance measured from the center of one groove (50) to the center of the adjacent groove (50), and the distance between the adjacent grooves (50) is longer than the width of each of grooves (50) by 2.4-times to 3.7-times.</p> |
