ABSTRACT:
In a tape transport portion of a tape recording and reproducing apparatus, the height of a tape is regulated without applying an excessive force to the tape. In a tape guide roller having a roller (9) which is brought in rotatable contact with a tape (2) and a flange (10) which regulates the height of the tape (2), the flange (10) has a tapered surface (15) opposing the inner surface of the tape (2) and a force for regulating the height of the tape (2) is generated by the cooperation of both a tape regulating end face (13) of the flange (10) and the tapered surface (15). Since the tape height regulating force is generated by two different parts, i.e., the tape regulating end face (13) of the flange (10) and the tapered surface (15), the tape (2) can be prevented from being buckled by a force applied thereto from a tape regulating end face of a flange. Thus, the tape guide roller does not damage the tape.
