In this process, second yoke 1133 comes back on second magnet 1131 magnetic flux of second magnet 1131 effectively through second coil 1132, improve actuating force with this.
In addition, the actuating force of Y-axis drive unit and X-axis drive unit should be greater than the elastic resistance power of Y-axis elastic component 1140 and X-axis elastic component 1150.
At this moment, because above-mentioned objective table 1120,1130 only connects by above-mentioned elastic component 1150,1160,, therefore can reduce above-mentioned drive unit institute energy requirement so when mobile, frictional force works hardly.
Because the direction along revisal digital vedio recording machine vibration drives imageing sensor 1160, can compensate the image flutter phenomenon of imaging on imageing sensor 1160.
As long as the actuating force that is added on Y-axis drive unit and the X-axis drive unit is eliminated, Y-axis objective table 1120 and X-axis objective table 1130 will return to initial position by the elastic force of Y-axis elastic component 1140 and X-axis elastic component 1150.
