Abstract

PURPOSE:To make well balanced driving possible and to operate a cantilever stably by disposing two magnetic yokes symmetrically with the coupling part between the cantilever and an elastic supporting body as a center. CONSTITUTION:Cantilever driving coils 8a, 8b, 8c, 8d drive a cantilever 2 in its longitudinal direction or rotate and drive the same with the coupling part between said lever and an elastic supporting body 5 as a fulcrum according to the directions of the electric currents to be supplied to these coils 8a-8d by the mutual effect with a permanent magnet 3 magnetized in the central axial direction of the lever 2. These are equipped in both end parts of the 1st and 2nd magnetic yokes 9a, 9b of which both end parts are respectively disposed on both sides of the cantilever 2 in such a way as to face both poles of the magnet 3 disposed near the trailing end part of the cantilever 2.
