Abstract
An electromagnetically suspended floating floor apparatus in which a floating floor on which machines are set up is suspended from an installation floor with electromagnetic actuators so that the floating floor is spatially separated from the installation floor whereby no vibration is transmitted to equipment on the floating floor. The floating floor apparatus comprises the floating floor suspended from the installation floor at a plurality of supporting points by electromagnetic actuators, a light emitting member, fixed to a beam or a pillar, which emits a horizontal light beam, and a photosensor fixed to the installation floor which outputs a position signal representing a position of incidence of the horizontal light beam to the electromagnetic actuators. On the basis of the position signal, the electromagnetic actuators control a vertical position of the floating floor.
