<p>PURPOSE:To prevent the variation in height and a tension state of a magnetic tape caused by disturbance in running or winding dispersion of a tape or the like. CONSTITUTION:This device is provided with a light receiving element 16 which detects the height of a magnetic tape 14 at the side of entering the magnetic tape of a cylinder 13, pressure sensitive sensors 6a, 6b, 6c which detect a tension state of the magnetic tape 14 on surface of a rotary guide roller 5 of a tape guide device 17 located at the side of entering the magnetic tape of the cylinder 13. Further, a inclination post 7 is two dimensionally free in inclination, and at below a post base 4, such shafts 11a, 11b are provided that they adjust an angle of inclination toward X direction for an inclination post 7 based on detected signals from the light receiving element 16, and also adjust an angle of inclination toward Y direction for an inclination post 7 based on detected signals from the pressure sensitive sensors 6a, 6b, 6c.</p> |
