ていた。[Problems to be Solved by the Invention] By the way, on a construction site, installation and removal of surveying equipment such as transit are repeated very frequently. Whenever a surveying instrument such as a transit is installed, it must be installed horizontally, and this leveling is visually checked with a bubble level built into the pedestal of the instrument, and the bubbles come to the center of the scale. As described above, three pedestal leveling screws are manually rotated to perform the adjustment. This leveling took a considerable amount of time, even for those skilled in measurement.

As shown in the drawing, first, when the present apparatus on which the transit 1 is mounted is installed at an arbitrary place, the elastic rod 4 attached to the transit pedestal 2
In addition, the weight 5 at the lower end of the elastic rod is pulled by the gravitational force of the earth, so that distortion occurs.
This strain is detected by three strain gauges 8 attached at equal intervals around the elastic bar 4. Then, the sensed distortion is transmitted to the three pedestal horizontal adjustment screw driving devices 6 by the electric wires 9, and each of the pedestal horizontal adjustment screw driving devices 6 is driven according to the degree of distortion, and each pedestal horizontal adjustment screw is driven. The screw 7 is rotated.
