Abstract
An object carriage system is developed which can suppress any vibration even if an object to be carried contains a source of vibration. The object carriage system comprises a carriage for carrying an object, a resilient supporting means for resiliently supporting the carriage over the floor, a vibration suppressing means for suppressing the vibration of the carriage relative to the floor, acceleration detecting means for detecting an acceleration of the carriage and producing a corresponding acceleration signal, a mass movably supported by the carriage, and driving means for driving the mass in the direction in which the acceleration takes place in accordance with the acceleration signal.
