IPC: G11B15/61
Filed: 1990-03-09
Abstract: PURPOSE:To prevent damage due to deformation of a tape and to decrease a traveling load on the tape and also to give regulating force to the tape at a requisite minimum by providing an adjusting mechanism capable of varying the inclination of a flange to a guide part independently of the guide part for guiding the tape with a circumferential surface of the flange of a tape guide to the flange. CONSTITUTION:A flange part (upper flange) 55 of the tape guide is adjustable in its inclination to a shaft 51 of the tape guide independently of the guide part (roller) 54 for guiding the tape with its circumferential surface. That is, the lower parts of plural adjusting screws 59 are brought into contact with the upper surface of the upper flange 55, and the upper flange 55 can be inclined in the desired direction by adjusting a screw-in amt. of each individual adjusting screw 59. By this method, deformation of the tape can be prevented without depending upon variations in a tape traveling course, etc., and since no excessive regulating force more than necessary is given at all, an end part of the tape can be prevented from flawing. Moreover, since the tape guide can be of a rotary type, the traveling load of the tape is reduced, and the reliability of the tape traveling can be improved.
