Vibration isolating table device

Claim 1

A vibration isolating table device comprising a base plate having an upper and a lower surface, a table body having an upper and a lower surface and for supporting an object to be mounted on the upper surface thereof, a vibration isolating means provided on the upper surface of said base plate and for supporting the lower surface of said table body horizontally in a floating state, the improvement comprising: a magnetic attraction means for attracting said table body toward said base plate against a floating force of said vibration isolating means, said magnetic attraction means being provided with a magnetic plate and a magnet means respectively provided on one and the other of the upper surface of said base plate and the lower surface of said table body such that said magnetic plate and magnet means are in opposition to each other, said magnet means having a magnetic force substantially the same as the floating force of said vibration isolating means; and means for generating a swing motion in said table body in response to an external force directly applied to said table body, said swing motion generating means being provided with a swinging member with its one end attached on the lower surface of said table body at the center portion thereof and with its longitudinal axis extending perpendicularly to the surfaces of said table body, and a weight member attached on the other end of said swinging member.
