Claims

[Claims for Utility Model Registration] A main body portion having a flat level surface, an A spirit level comprising a number of display lamps attached to the main body and arranged in grids in the X and Y directions at appropriate intervals to form a plurality of X rows and Y rows, the above-mentioned X direction reference The part and the Y direction reference part have a curved surface curved in an arc shape along the X and Y directions, respectively, with respect to the level surface of the main body part, and a long integral plate disposed on the curved surface along the curved direction. an electrode, disposed on the curved surface along the curve direction, with a distance from the plate electrode, and with reference to a central one located at the bottom of the curve and corresponding horizontally in the X and Y directions, respectively; a selection electrode which is divided into a plurality of parts, which can roll along the curve on the curved surface and on the plate electrode and the selection electrode, the outer surface is conductive, and one end is always connected to the plate electrode; and a rolling element whose other end is always in contact with at least one selection electrode, and one of the plate electrodes of the X-direction reference part and the Y-direction reference part is connected to a power source. Each of the X rows of the indicator lamps is connected to each selection electrode of the X-direction reference section, and each Y row of the indicator lamps is connected to one of the selection electrodes of the Y-direction reference section. A spirit level characterized by being connected to each selected electrode in a corresponding manner.
