Abstract:
An optical pickup device comprising:a laser light source for emitting a laser beam; an optical system for converging the laser beam onto a recording face of an optical recording medium, and for reproducing information recorded on the optical recording medium in accordance with a returning light beam reflected by the recording face, the optical system having a system optical axis; a device frame on which the laser light source is mounted, the device frame including: a supporting member for supporting the laser light source while allowing the laser light source rocking about a rocking center line which intersects the system optical axis orthogonally; and a restricting member for supporting the laser light source while restricting a motion of the laser light source other than the rocking motion, wherein the laser light source is configured to have a cylindrical casing and a circular stem coaxially attached to the cylindrical casing; wherein the device frame includes a recessed portion into which the laser light source is press-fitted; wherein the restricting member is provided as part of an inner face of the recessed portion for supplying only parts of an outer periphery of the stem situated on the rocking center line; and wherein the supporting member is provided as convex portions formed on a bottom portion of the restricting member for supporting only parts of an end face of the stem situated on the rocking center line.
