<p>PURPOSE:To always stabilize the traveling position and traveling direction of a tape and, simultaneously, to prevent the gradation of characteristic even in the case of a use under a high temperature for a long time by preventing the tape from being brought directly into contact with a tape guide, and forming the tape guide side edge of a tape traveling surface and the reference surface and the slope of the tape guide successively or overlappingly. CONSTITUTION:Tape guides 6 and 6' are prevented from being brought into contact with a tape 5 except for the reference surface and slope. Namely, recessed parts 9a, 9a' and 9b, 9b' are formed at the outside of the traveling area of the tape at both edges of a tape traveling surface 2, projecting parts 6a, 6a' and 6b, 6b' of the tape guides 6 and 6' are arranged at the inside of them, respectively, and the reference surfaces and slopes are provided on the projecting parts 6a and 6a' and the projecting parts 6b and 6b', respectively. The tape guide side edge of the tape traveling surface 2 and the reference surfaces and the slopes of the tape guides 6 and 6' are successively or overlappingly formed. Thus, the traveling position and traveling direction of the tape can be always stabilized, and simultaneously, the degradation of the characteristic at the time of using under the high temperature for the long time can be prevented.</p> |
