<p><P>PROBLEM TO BE SOLVED: To provide a display which is not restricted in place for installation thereof, and prevents tumbling by safely absorbing external vibrations. <P>SOLUTION: An angular velocity sensor 103 installed in a housing measures an angular velocity based upon vibrations applied to the housing, and a cancel processing decision unit determines the angular velocity and amplitude of the vibrations applied to the housing from the angular velocity measured by the angular velocity sensor 103. A vibration cancel control unit determines a movement amount for canceling the vibrations using force of reaction by movement of a weight on the basis of information on the angular velocity and amplitude determined by the cancel processing decision unit, and also moves the weight provided in the housing. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
