摘要:
An optical disc driving device for use in an optical disc apparatus is equipped with an objective lens, a lens holder for holding this lens, and upper and lower support springs for supporting the lens holder. Each support spring consists of a pair of conductive springs which are electrically separated from each other in a plane. Each pair of conductive springs includes straight spring sections extending straight to pass a central axis which is parallel to the optical axis of the lens holder and which passes the center of gravity of the same. End portions of these conductive springs are joined to the lens holder by means of rubber members.
