摘要： PURPOSE:To protect the eye-sight of workers and to perform the measurement smoothly, by providing a light shielding body, whose displacement can be restored, around the axis of projected laser light, and providing a means, which detects the displacement. CONSTITUTION:A light shielding body 41 is attached around an axis 33 of projected laser light in a displacement gage 3. Said light shielding body 41 is attached to a flexible plate 42 and formed so that the body can be displaced and restored in the directions of arrows. A limit switch 44 detects the displacement of the light shielding body 41. When the light shielding body 41 is displaced by the amount exceeding a specified value, the switch 44 is actuated. The protruded length l of the light shielding body 41 from the displacement gage 3 is smaller than the lower limit Lmin of the measuring range of the displacement gage 3. In this configuration, the worker's eyes are protected against the laser light by the light shielding body. Since the displacement gage never exeeds the lower limit Lmin, the measurement can be performed smoothly.

摘要： PURPOSE:To simply set the position of an angle change mechanism to a three- dimensional drive mechanism with high accuracy, by effectively putting the light spot irradiation function of a light spot detection sensor and the irradiation angle change function of an angle change mechanism to practical use. CONSTITUTION:To the surface of an object 30 to be irradiated, one reference line 31, of which the Y-coordinates are constant value, is drawn. Next, an angle change mechanism 4 and a three-dimensional mechanism are driven so as to form the image of the light spot P1 of a light spot detection sensor 3 to one point Pr on the reference line 31. Subseqeuntly, the angle change mechanism 4 is rotated around an S-axis by an arbitrary angle thetas and the position of the light spot P2 on the object 30 to be irradiated at said angle is confirmed. When no light spot P2 is rotated by a proper amount. By repeating these operations before the position of the light spot P2 comes onto the reference line 31, the position of the angle change mechanism 4 is set to the three-dimensional drive mechanism.

摘要： PURPOSE:To shorten the measuring time, by providing an operation control mechanism, which drives and controls the driving amount and the attaching angle of a three-dimensional driving mechanism of a displacement gage, and crossing the axis of the rotary center of an angle changing mechanism and the extended line of the optical axis of emitted light. CONSTITUTION:A displacement gage 40 is attached to a cross head 22 over a body to be measured 1, which is placed on a base table 20. The cross head 22 is slidden in an arm 23 of a three-dimensional driving mechanism and driven right and left by a motor 26. Therefore, the displacement gage 40 can be moved in the direction of the x axis. Driving in the direction of the (y) axis is performed by a longitudinal feed screw 28 and a gear box 30. The entire driving mechanism on a base table 32 is driven in the direction of the axis by a motor 31. Meanwhile, an angle changing mechanism 21 rotates an arm 34 around a rotating central shaft 33, which is in parallel with the (x) axis. An angle changing mechanism 21', which is attached to the lower end of the arm 34 turns the displacement gage 40 around a rotating central shaft 33', which is in parallel with the (z) axis.
