Claims

[Claims for Utility Model Registration] 1. A device that moves up and down along a support column while being held by guide rollers provided in pairs at the top and bottom.
a frame of the body; a frame driving means for moving the frame up and down by a gear self-propelled by an electric motor along a screw jack axis; a beam having both ends engaged with the pair of frames; A positioner comprising: a beam tilting means for tilting with respect to a frame; and a rotary table rotatably provided on the beam for fixing a workpiece. 2. Registration of a utility model in which each driving electric motor of one frame driving means has a rotation speed sensor, and has means for controlling the electric motor according to the detection results of the pair of rotation speed sensors. A positioner according to claim 1. 3. The tilting shaft of the beam tilting means is inserted into a recess provided at a position across the tilting shaft, and the length in the vertical direction is shorter than the length in the vertical direction of the recess and the radius of the tilting shaft. The positioner according to claim 1, wherein the positioner is held via a bearing metal having a concave surface with the same radius of curvature, and is movable only in a direction perpendicular to the axial direction of the tilting shaft. 4. The positioner according to claim 1, wherein the beam tilting means is provided only on one of the pair of frames.
