摘要：
A screw surface flaw inspection method and an apparatus therefor, which projects light onto the surface of a screw, the light being scanned axially of the screw, and a detector which picks up the reflected light from the projected surface and sends an output signal to a signal processing circuit to thereby detect the flaw on a basis of time base variation of the intensity of reflected light. The method and apparatus enables the inspection of minute flaws rapidly and exactly.
