Abstract

PURPOSE:To prevent a vibro-isolating bed from large vibrating braking an equipment, when it is driven, in its own vibration and displacement by driving a brake by a start signal, received from a power driving mechanism in a side of the vibro-isolating bed, to be released after the predetermined time. CONSTITUTION:Previously transmitting a stage start signal from stage driving mechanisms 2', 2' in a sample stage 7, when the stage 7 is driven, a computer 6 applies a brake 4 in accordance with the start signal, preventing a vibro- isolating bed 1 from large vibrating and releasing the brake 4 after the end of driving. While even without the signal, detecting by a sensor 5 a vibration and acceleration of previously assigned value or more for the generation of large floor vibration, the brake 4 is shockingly applied only for the previously assigned time width thereafter slowly released. By the method thus obtained, removing a vibration applied to a supporting structure or the vibro-isolating bed or the like while expectedly controlling an equipment, providing a power driving mechanism, in its own generated vibration and displacement when the equipment is driven, the vibro-isolating bed is prevented from large vibrating.
