Abstract

PURPOSE: To enable to detect the center position with simplified operational processing, by enabling to rotate the line sensor and the object to be measured relatively and processing the measured data for operation through scanning the object to be measured toward circumference.
CONSTITUTION: The line sensor 10 is located opposingly to measure the radius corresponding part of the circular object to be measured 1, it is enabled for rotation for an arbitary angle with the rotary driving unit 12, and it is scanned toward circumference. Further, the measured data is converted into digital signal at the binary circuit 14, and the count value corresponding to the radius size of the object to be measured opposing to each rotating angular position of the line sensor 10 is counted 15 and operational processing is made at the processor 16 to detect the center position. Thus, since the measured data for the part corresponding to radius direction from the line sensor possible for relative rotation is processed only with the count value, the operational processing is simplified and the processing speed can be increased.
