Claims

[Scope of utility model registration request]

This is a device that moves relatively over the outer surface of a square specimen to detect flaws on the inner outer surface of the specimen using the angle method using ultrasonic waves. a guide roller that rolls on each; a tank that stores a liquid that propagates the ultrasonic waves emitted from the probe; and a tank that is immersed in the liquid and that reflects the ultrasonic waves emitted from the probe. , a reflecting member that allows the light to enter the interior from one outer surface of the test material and guide it to the outer surface side of the test material adjacent to the outer surface; and a vibration means for vibrating a reflecting member to scan in a direction substantially perpendicular to the direction.
