PURPOSE:To make a titled mechanism small-sized, and to simplify its assembly, by fixing a magnet to a lens supporting block which is supported so as to be freely displaceable in the two-dimensional direction, and orthogonally winding a coil winding to its opposed magnetic plate. CONSTITUTION:To both left and right sides of a supporting body 1, one end of tracking elastic plates 2a, 2b is made to adhere and fixed, the plate surfaces are opposed in parallel, and to the other end of these elastic plates 2a, 2b, an almost rectangular parallelepiped-like intermediate block 3 is made to adhere and fixed, and the intermediate block 3 is supported so as to be displaceable to the left and right. Also, to the upper surface and the lower surface of this intermediate block 3, one end of 2 tracking elastic plates 4a, 4b is made to adhere and fixed, and to the other end of these elastic plates 4a, 4b, a lens supporting block 5 is made to adhere and fixed, the lens supporting block 5 is supported so as to be displaceable in the upper and lower directions, too, and on the lens supporting block, a through-hole for passing in advance is formed, a lens tube body 6 into which an objective lens has been inserted is fixed onto the through-hole, a pair of focusing magnets 7, 7 are fixed to both sides of the through-hole, and a tracking magnet 8 is fixed to the right end of the block 5. |
