摘要： PROBLEM TO BE SOLVED: To remove dust adhered to and accumulated on an objective lens in an optical disk reading device.
SOLUTION: The optical disk reading device includes a mover 41 which retains objective lenses 35a, 35b, a wire 42 which movably holds the mover 41, and a vibration means for vibrating the mover 41. By supplying an alternate current (or a pulse current) having a resonance point frequency equal to a natural frequency f
0 when the mover 41 is vibrated by a resilient restoration force of the wire 42 to electromagnetic coils 47a, 47b, 47c, the vibration means vibrates the mover 41 by allowing an external force (magnetic action force between the electromagnetic coils 47a, 47b, 47c and a magnet 46) to act upon the mover 41 with a natural vibration period T
0 when the mover 41 is vibrated by the resilient restoration force of the wire 42. Thus, by the resonance of the mover 41, the vibration of the mover 41 is amplified, and the vibration of the mover 41 sufficient to remove the dust adhered and accumulated on the objective lenses 35a, 35b is obtained.
