Now, by operating the operating shaft C, the movable table 38 is set at a desired position in the front, rear, left, right, or diagonal direction, that is, the scanner 20 is set at the optimum position with respect to the object to be inspected. In this case, by operating the operating shaft B, the side plate 32 and the frame 2 can be moved around the shaft 34.
3 and 24 in the front-back direction, and the scanner 20 linked thereto can be set at a desired angle. Here, by driving the motor M, the pinion 2 rotates and the sector gear 1 meshing with the pinion 2 rotates.
can be rotated forward and backward over a predetermined angular range. That is, when the sector gear 1 meshing with the pinion 2 rotates in one direction as shown by the arrow, for example, counterclockwise, it eventually comes into contact with the protrusion 3 of the cam plate 5, and when both rotate in the engaged state, the stepped portion The actuator 9 of the micro switch 8 comes into sliding contact with the cam 7 forming the cam 7 to switch the electric circuit, and as a result, the motor M rotates in the opposite direction. As a result, the sector gear 1 rotates in the opposite direction, that is, clockwise, and
Eventually, it comes into contact with the other protrusion 4 of the cam plate 5, and when both rotate further in the engaged state, the actuator 9 of the micro switch 8 leaves the state of sliding contact with the cam 7 and returns to its original position. Switch the electric circuit again to return the motor M to its previous rotational state,
Rotate the sector gear 1 counterclockwise. and,
This repetitive operation is continued thereafter. Therefore, the rotation of this sector gear 1 is caused by the bevel gears 11, 12 and the drive shaft 1.
3. Bevel gears 14, 15, shaft 18 and bevel gear 1
The shaft 19 can be rotated through the shafts 6 and 17, and the scanner 20 provided on the shaft 19 can be rotated in forward and backward directions over a required angular range.

如く走査することができる。 However, if the operating shaft A is operated to set the rack 29 that meshes with the gear 30 at approximately the center position,
The cam plate 5 is located at approximately the center position with respect to the motor M,
The movable angle range of the scanner 20 can be set so that it rotates around the position [a] in FIG.
Next, when the operating shaft A is turned to the right to move the rack 29 to the right, the cam plate 5 is deflected as shown by the arrow around the shaft 10 by the amount of movement, and the sector gear 1 is also rotated relatively. Then, the drive shaft 13 is moved to the right, and the center of rotation of the scanner 20 is moved to the position [b] in FIG. By tilting it, it is possible to always scan toward the center of the object to be inspected [D] as shown in [C 1 ]. Conversely, when the operating shaft A is turned to the left, the cam plate 5 is similarly biased in the opposite direction by the amount of movement, and the drive shaft 13 is shifted to the left, and the center of rotation of the scanner 20 is rotated. Since it can be moved to the position [c] in Figure 4 and the center of the rotation angle of the scanner 20 is tilted, it can always scan toward the center of the object to be inspected [D] as shown in [C 2 ]. .

Since the forward and reverse directions are switched by the contact of the protrusions 3 and 4 by the swinging of the cam 7 and the sliding contact of the actuator 9 by the cam 7, by transmitting this rotation, the scanner 20
The desired scanning can be performed by rotating forward and backward over a certain angular range. Further, the position of the scanner 20 is moved in parallel as necessary, and even during the movement, the center of the rotation angle is always tilted toward the center of the object to be inspected according to the range of forward and reverse rotation controlled by the drive device. 1 Scanner 2
Since it is possible to thoroughly scan any position using 0, it is possible to achieve the same effect as scanning by a plurality of scanners.
