Claims

[Scope of utility model registration request]

The upper part of a rotating shaft rotated by a rotation mechanism such as a motor is rotatably supported on the stage board side, and a feed screw is engraved on the outer periphery of the rotating shaft. By providing one or more housing cylinders each having a threaded portion formed on the periphery to engage with the threaded portion, or a plurality of small-diameter housing cylinders that are screwed together at the threaded portion and sequentially housed in a large-diameter housing cylinder, A rotating shaft is screwed into the upper storage cylinder, and a threaded part is formed on the inner circumference to be screwed into the feed screw of the outermost storage cylinder, and a holding cylinder that can accommodate the outermost storage cylinder is fixed to the lower base material side. death,
An upward movement linkage mechanism in which the rotating shaft and the housing tube rotate and move up the housing tube below each by one rotation of the rotating shaft, and the rotating shaft and the housing tube respectively move the housing tube below by rotating the rotating shaft in the opposite direction. A stage elevating device characterized by being provided with a downward movement linkage mechanism that rotates in reverse and moves downward.
