PURPOSE:When flaws of a wide object to be examined is going to be examined by placing a plurality of flaw detectors, only the signals detected by the flaw detector whose detection section is assigned to the standard end part of the object to be examined is read out by shifting the number of bits corresponding to the length after subtracting the length of the object being examined within that section from the scanning length of the detection sections, whereby the easy detection is made possible. |
