各柱体１０との間に介在するボールベアリングである。FIG. 1 is a perspective view showing a horizontal plane maintaining device according to the present invention. In the same figure, what is indicated by the symbol l is a housing having a spherical space 2 inside, and has a flat surface as a reference surface.
It is configured to house the components of the shake detection WIM. A liquid 3 that fills approximately 2 volumes of the space 2 is stored in the housing 1. Reference numeral 4 denotes a floating plate having a laser light source 5 as a light source in its center, which is a circular plate having approximately the same cross-sectional shape as the center of the space 2, and is held on the surface of the liquid 3. There is. The laser light source 5 of the floating plate 4 is connected to an electric signal transmitter 7 by a cable 6, and is configured to emit light toward a point P on the spherical surface of the space 2. Reference numeral 8 denotes a light receiving sensor corresponding to the laser emitting source 5, which is provided along a curved surface on the spherical surface of the space 2, and has a deviation angle θ of the emitted light beam g1 emitted from the laser emitting source 5 (with respect to the emitted light beam g0). ) is configured to detect. Reference numeral 9 denotes an electromagnetic controller having a coil 11 for driving a pillar 10 for supporting the table, and is connected to the light receiving sensor 8 via a cable 12. Reference numeral 13 denotes a stand having a rectangular shape in plan view, which is provided at the center of the base 15 by a spring 14, and is movably held by the column 10. Moreover, l6 is a ball bearing interposed between this stand 13 and each of the columns 10.
なお、前記球形空間２の中心と前記浮板４の中心とは略
一致しているものとする。It is assumed that the center of the spherical space 2 and the center of the floating plate 4 substantially coincide with each other.

ある。In the horizontal plane maintaining device configured in this way, the light receiving sensor 8 detects the deviation angle of the emitted light beam, and the column supporting the table 10 is driven and controlled by the electromagnetic controller 9 according to the detected angle. can. At this time, the laser light source 5 emits light due to the electric signal propagated from the electric signal transmitter 7 via the cable 6, but this emitted light beam is directed vertically upward because the floating plate 4 on the surface of the liquid 3 is always horizontal. be.

Since the emitted light beam g is received at point P2, it is possible to detect the deviation angle θ of the emitted light beam when it is horizontal and when it is tilted. On the other hand, based on the information on the deviation angle θ, the electromagnetic controller 9 causes a current corresponding to the deviation angle θ to flow through each coil l1, and the pedestal 13 on the base plate 15 is held horizontally.
