PURPOSE:To adjust minutely a feeding angle of a tape clipped with a capstan shaft and a pinch roller, by the constitution that the shaft mounting the pinch roller is tilted to a bracket and an optional tilt state is kept. CONSTITUTION:The inclination of a shaft 17 in (b) or (c) direction is adjusted by turning an adjusting bush 13 after mounting a pinch roller 18. In tilting the shaft 17 toward the (b), a tip of a screw driver is touched to a groove 13d of the adjusting bush 13 and it is turned counterclockwise. In turning by a prescribed angle alpha (about 90 deg.) counterclockwise, the upper end of the shaft 17 is moved by a distance Da to the right end of a long hole 11d and the shaft is tilted by a prescribed angle toward the (b). In tilting the shaft 17 toward (c), the adjusting bush 13 is turned clockwise. In turning clockwise by a prescribed angle beta (about 60 deg.), the upper end of the shaft 17 is moved by distance Db toward left in a long hole 11d and the shaft is tilted toward (c) by a fixed angle. |
