Abstract
A support unit () for supporting an OPM holder () so as to be vertical to the laser beam axis is disposed in the lower part of the OPM holder (). A rotary shaft () is inserted into the support unit () and rotary shaft support unit (), and the OPM holder () and DT base () are assembled together. Thus, a rotation support unit () is composed. The rotation support unit has a degree of freedom in the rotating direction of arrow (). On the other hand, in the lower part of an RM holder (), a support bar () is provided. At the DT base (), a rotating element () and a rotating element support unit () supporting the rotating element are composed so as to support the support bar. Thus, a slider structure () slidable in the optical axis direction is formed. The slider structure has a degree of freedom in the direction of arrow ().
