置。 The optical disk master S carried on the turntable 2 is rotated by the spindle shaft 1, and the pressing member 42 is brought into contact with the outer peripheral end surface of the optical disk master S to move it along the horizontal axis XX. This is a device that aligns the rotation center of S with the rotation axis of the spindle shaft 1, and aligns the bed 5 with the horizontal axis X-X.
a movable base 10 that slides along the movable base 10;
vertical axis Y-Y through the coarse adjustment mechanism section 20 that moves by rotating the coarse adjustment feed screw rod 21, and the fine adjustment feed screw rod 31 screwed onto the movable base 10.
A fine adjustment mechanism section 30 is provided with a taper section 33 that moves in the direction, and is biased in the direction of contacting the surface of the taper section 33, and moves a distance corresponding to the amount of displacement of the taper section 33 along the horizontal axis XX. a pressing mechanism section 40 that slides along the shaft and has the pressing member 42 at its tip;
A rotary centering device for evaluating optical disk masters, including:
