Pinch roller and pinch roller apparatus having a self-alignment function |
摘要 |
A pinch roller apparatus is disclosed which fully satisfies the requirements of tape running stability and durability of the bearing. A roller shaft is arranged inclined such that the tip end is close to the capstan. The angle of inclination ( alpha ) of the roller shaft with respect to the axis of the capstan is in the range of 0 DEG < alpha </=7 DEG . Also, when clearance in the radial direction between the roller shaft and the plain bearing is represented by "a" and the effective length in the axial direction of the plain bearing is represented by "b", then the relation 0.002</=a/b</=0.05 is satisfied.
