ABSTRACT:
An anti-vibration system includes a supporting member for supporting a driving mechanism, an acceleration sensor for detecting acceleration of the supporting member, a driving unit for driving the supporting member, a storing unit for memorizing offset data to be used for offsetting an output of the acceleration sensor, an offset unit for offsetting an output of the acceleration sensor in accordance with the offset data memorized in the storing unit, a control unit for producing a driving signal in relation to the driving unit, on the basis of an output of the offset unit, a renewing unit for renewing the offset data during a non-driving period of the driving mechanism, on the basis of an output of the acceleration sensor, a discrimination unit for discriminating whether the offset data should be renewed or not, during the non-driving period of the driving mechanism, on the basis of an output of the acceleration sensor, in which the renewing unit renews the offset data in response to an affirmative discrimination result of the discrimination unit, in which the discrimination unit performs discrimination again to the offset data renewed by the renewing unit to verify the offset data, and a notifying unit for notifying disorder provided that a negative discrimination result is not obtained after the discrimination is made a predetermined number of times by the discrimination unit.
