Patent ID: 7073185

Claim:
An objective lens driving device comprising: a lens bobbin provided with an objective lens; a magnet provided on said lens bobbin; a coil unit for causing movement of said lens bobbin along with said magnet in a direction parallel to an optical axis of the objective lens and in a plane perpendicular to the optical axis of the objective lens; a stationary unit provided with said coil unit; and an elastic supporting unit formed of a stainless material, provided between said stationary unit and said lens bobbin for supporting said lens bobbin for movement in a direction parallel to the optical axis of said objective lens and in a plane perpendicular to the optical axis of said objective lens and including, a plurality of linear supporting members each having one end thereof mounted to said lens bobbin and having an opposite end mounted to said stationary unit, wherein said elastic supporting unit is formed as a first elastic supporting part and a second elastic supporting part, each said first and second elastic supporting part being respectively constructed having two connecting pieces, each of said two connecting pieces interconnecting ends of two supporting members, of said plurality of linear supporting members so that said two supporting members extend parallel to each other, and wherein said first and second elastic supporting parts are arranged parallel to each other on respective sides of said objective lens, so that said objective lens lies between said first and second elastic supporting parts.
