PURPOSE:To provide a method which supports a ferrite core having a half circular arc-shaped peripheral edge on a rotary table and align the enter point of the half circular arc of the peripheral edge with the rotation axis of the rotary table in a non-contact manner, and its device. CONSTITUTION:A line sensor 6, which reads the coordinate values of a point Y that a peripheral edge 1a of a ferrite core intersects a Y-Z surface, is provided on a Z-axis, a rotary table 8 is rotated to read the coordinate values of a plurality of pieces of points on the half circular arc-shaped peripheral edge 1a and the read coordinate values are inputted in an arithmetic control device 9. The device 9 calculate the coordinate values of the center point O' of the half circular arc of the edge 1a on the basis of the coordinate values of the plurality of pieces of the points and at the same time, actuates an X-Y table via a table driving device 10 and moves the center point O' on the Z-axis. |
