Patent ID: 7451465

Claim:
An optical pickup device including an optical head that, while being guided by a pair of guide rods supported on a chassis, moves so as to reciprocate across a recording surface of an optical disc in a direction of a radius thereof, wherein the guide rods receive, from an elastic member fitted to the chassis, a restoring force of the elastic member and are thereby loaded with a force that tends to move the guide rods away from the recording surface of the optical disc, and at a position close to each of at least three of a total of four ends of the guide rods, an adjustment screw is fitted to the chassis so as to, when rotated, move close to and away from the recording surface of the optical disc, so that a position in which the guide rods remain loaded with the force is determined as a result of an outer circumference of the guide rods at the at least three ends thereof making contact with a flat inner end face on a head portion of each of the adjustment screws.
