Claims

[Scope of utility model registration request]

It has a flaw detection probe that is held by a probe holding member attached to a rotary drum that rotates around the passage of the inspected material having a circular cross section that is linearly fed and is disposed close to the periphery of the inspected material, and the rotating The drum has a probe forward and backward movement mechanism that is operated from the outside to move the probe holding member back and forth so that the flaw detection probe is adjusted to move toward or away from the center of rotation. A probe remote adjustment device for a rotary flaw detector, the sensor arm having a distance sensor that senses the distance to the flaw detection probe, a sensing position for sensing the distance to the flaw detection probe, and a retreat outside the rotating drum. a sensor stand including a movement mechanism for moving the distance sensor between the positions and an adjustment mechanism for moving and adjusting the sensor arm so that the distance sensor is moved in the direction of the movement adjustment of the flaw detection probe; an external drive mechanism capable of acting on and operating the probe forward/backward movement mechanism to adjust the movement of the flaw detection probe; and a coupling mechanism for changing the external drive mechanism from a non-operating state to an operating state. Applying a control signal to a tracking adjustment device and the adjustment mechanism of the sensor stand to move the distance sensor by a desired amount, and actuating the external drive mechanism of the tracking adjustment device based on the resulting change in the signal from the distance sensor. and a control means for causing the flaw detection probe to move by a desired amount in accordance with the movement of the distance sensor.
