Abstract

PURPOSE:To enable to keep an excellent pressing state in a tape running for a long time, by taking a pinch roller as a shape chamferred for the edges and making a contact length with a capstan equal to a tape width. CONSTITUTION:The shape of a pinch roller 3 which presses and clips a magnetic tape with a capstan 3 in constant speed rotation is taken as a shape chamfering the edge circumference of a rubber 5 covering a cylinder as shown in Figure. The width of a tape pressing part 9 at the side in contact with the tape is made coincident with the tape width. Thus, even with a tape run for a long time, since no drum shape deformation is caused, normal pressing of the tape can be kept.
