PURPOSE:To attain ease of focusing control and tracking control by processing an elastic metal thin plate in a waving form in an optical reproducing device using laser light and using the plural thin plates so as to eliminate spurious resonance. CONSTITUTION:An object 1 to be driven comprising an optical lens and a drive coil is supported to a frame 3 by eight support members 2-1-2-8. The support members 2-1-2-8 are formed by processing metallic thin plate in a waving form and obtained by punching or etching. Thus, the objective 1 to be driven is arranged with good balance at a prescribed position and moved freely in any direction from a stationary position. Further, since the degree of freedom is suppressed around the shaft, the tilt of the optical axis fixed to the object 1 to be driven is decreased. |
