Claims

[Claims for Utility Model Registration] A support plate 1 with a hole 1A in the center, four reference contacts 2A to 2D arranged at equal intervals on the upper part of the support plate 1, and reference contacts 2A to 2D. a contact plate 3 in contact with the contact plate 3; a contactor 4 attached to the first surface 3A of the contact plate 3; and a recess 3C provided in the second surface 3B of the contact plate 3.
The ball 5 that enters the body, the shaft 6 that is attached to the main body 9 and applies a force in the direction of pushing the ball 5, and the four displacement detectors 7A that are attached to the main body 9 and correspond to the positions of the reference contacts 2A to 2D, respectively.
7D, and a computing unit 8 that calculates displacement from the outputs of the displacement detectors 7A to 7D, the contactor 4 is made longer than the sum of the thicknesses of the support plate 1 and the reference contacts 2A to 2D, and the support plate The contactor 4 is taken out from the hole 1A of the contact plate 3, and the displacement detectors 7A to 7D are brought into contact with the second surface 3B of the contact plate 3. A detection device for three-dimensional position measurement, characterized in that it performs calculations using .
