際しては、超音波プローブを固定し被処理体の角材の方
を移動させるため、極めて作業性が悪い問題があった。[Conventional technology and its problems] Conventionally, defects existing inside a square timber such as a billet have been determined by applying an ultrasonic probe to only one side of the square timber, which is the object to be processed, and then detecting the inside of the square timber from the ultrasonic probe. The ultrasonic waves sent towards the target are reflected when they hit casting defects such as cracks,
This was done by receiving reflected waves. In this way, since this is a defect determination method called vertical flaw detection in which the ultrasonic probe is detected by contacting only one surface of the square timber, the measurement results such as the position and size of the defect may vary if the flaw detection surface of the ultrasonic probe is different. There was a problem with discrepancies. Furthermore, when detecting defects, the ultrasonic probe is fixed and the square timber of the object to be processed is moved, resulting in extremely poor workability.

At least one pair of arms that have contacting ultrasonic probes and can be bent freely, a signal processing and recording unit that transmits and receives signals to and from each of the ultrasonic probes, and a drive means for the manipulator are disposed at one end. This is a defect determination and recording device for square timber.
