This laser displacement meter irradiates the surface of the object with a laser beam through a light emitting lens, captures some of the scattered light from the surface with a light receiving lens, and forms an image on the optical position detection element. More specifically, the upper laser displacement meter 10a is connected to the pallet 11. (Fig. 3) and the upper surface of the concrete product C (Fig. 4) is irradiated with a laser beam, and the lower laser displacement meter lOb installed corresponding to the upper laser displacement meter 10a is connected to the pallet. A laser beam is radiated onto the lower surface of the laser displacement meter 11, and each of the laser displacement meters 10a and 10b captures a portion of the scattered light with a light receiving lens and forms an image on an optical position detection element.

Therefore, in this embodiment, as the pallet 11 moves, the upper laser displacement meter 10a changes from irradiating the upper surface of the pallet with a laser beam (FIG. 3) to irradiating the upper surface of the concrete product C. Condition (Figure 4)
When the height of the measured surface changes, the beam spot position on the optical position detection element moves because the height of the surface to be measured changes. and,
Since the amount of movement corresponds to the height displacement, that is, the thickness of the concrete product, the optical position detection element converts the amount of movement into an electrical signal, which is processed by a microprocessor to determine the displacement (of the concrete product). thickness).
