ABSTRACT:
The flaw detecting apparatus comprises a sensor head including a first sensor for detecting the center of the center hole and a second sensor for detecting a flaw. A driver moves the sensor head along a first line passing through the center hole and then along a second line passing through the center of the center hole and perpendicular to the first line, thereby placing the sensor head at a position facing the center hole, on the basis of the output of the first sensor. Subsequently, the driver rotates the sensor head to a predetermined position where a flaw is detected, on the basis of the output of the second sensor.
