Title: Optical measuring device for shape of body
Inventor: TAKAGI YUUSUKE
IPC: G01B11/30
Filed: 1983-07-15
Abstract: 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.
