Abstract

PURPOSE:To raise response sensitivity by supporting an objective lens by one end parts of four rocking shafts, supporting the element of one side of a magnetic driving mechanism, consisting of two electromagnetic elements opposing to each other, by the four rocking shafts, supporting the element of other side by a supporting member, and equalizing weight balance at both sides positioned with a part, supported by the supporting member of the rocking shaft, between. CONSTITUTION:As for four rocking shafts 10,10', 11,11', the weight balance of two parts of a left and a right sides, positioned with the part, supported by a respective supporting wall 6, between, is equalized. Namely, the weight of hinge members 14,14', 15,15', a lens supporting body 19, the objective lens 21, a yoke 23, a magnet 24, etc., supported by four rocking shafts directly or indirectly, and their arranged positions are set so that the weight balance of two parts in the axial direction of the rocking shaft comes equal. Accordingly, whatever direction the rocking shaft comes in, loads acting in the direction of gravity of the left and the right sides, positioned with the part, supported wall 6, between, come always to be balanced.
