发明名称 Vibration isolating apparatus and vibration isolating table
摘要 <p>A vibration isolating apparatus and a vibration isolating table for reliably controlling vibration of an object of vibration isolation. A coil-mounting main body (18) is mounted on the vibration isolating table and a yoke-mounting main body (20) is mounted on a floor (14). A coil (24) of the coil-mounting main body (18) is disposed in a gap of a yoke (26) where magnetic flux passes through, in a state in which the coil does not contact the yoke. An acceleration sensor for detecting a vibration is mounted on the vibration isolating table and is connected to a controlling device. The controlling device receives an acceleration detecting signal from the acceleration sensor and controls an electric current applied to the coil (24) such that vibration acting on the vibration isolating table becomes zero. Since the coil (24) and the yoke (26) are disposed in a non-contact state, even though vibration shifted in any direction other than a direction in which the coil (24) moves is generated on the floor (14), the vibration is not transmitted to the vibration isolating table. &lt;MATH&gt;</p>
