Claims

[Claims for Utility Model Registration] (1) A slider mounted on a base so as to be movable up and down along a column erected thereon, and a measuring means for reading the amount of relative displacement between the slider and the column. In the height gauge, the slider is provided with a drive shaft for raising and lowering the slider that engages with a rack carved in the support column, and a pulley and a handle are each rotatably attached to the drive shaft and are arranged at a constant interval. At the same time, a displacement body having disc-shaped gears on both end faces is attached to the drive shaft between the pulley and the handle so that it can be displaced in the axial direction and rotated synchronously, and this displacement body is displaced in the axial direction of the drive shaft. A switching means is provided for meshing one of the disc-shaped gears with the disc-shaped gear of the pulley or the handle, and the slider can be selected to move automatically or manually by a motor connected to the pulley or a knob of the handle. A height gauge configured as follows. (2) In paragraph 1 of the claims for utility model registration,
The switching means includes a switching knob having a movable element that is displaceable in the axial direction in a hollow portion formed in the center of the drive shaft, and a groove that passes through a groove formed along the axial direction in the drive shaft. and a height gauge comprising a pin that connects the movable element and the displacement body to each other, and a positioning means for selectively locking the switching knob in one of two positions in the drive shaft direction. . (3) In paragraph 2 of claims for utility model registration,
The height gauge is characterized in that the diameter of the pin is smaller than the groove width of the drive shaft. (4) Scope of claims for utility model registration, paragraph 2 or 3
2. The height gauge according to item 1, wherein the pin and the displacement body are connected with each other with the pin being freely inserted in the radial direction of the displacement body.
