チセンサ。[Scope of Claim for Utility Model Registration] An elevator in which a lead ring is screwed onto a lead screw shaft and an elevator table is fixed to the lead ring, and the elevator table is moved up and down by the rotation of the lead screw shaft, as described above. The first semicircular shape on the lead screw shaft.
At the same time, a semicircular second variable capacitance member is arranged separately from the first variable capacitance member, and a capacitance change due to rotation of the first variable capacitance member is utilized. An elevator pitch sensor that detects the position of an elevator table.
