ABSTRACT:
An optical-pickup feeding device includes a chassis, a guide shaft supported on the chassis, a feeding motor on a main shaft of which a lead screw is formed, a connecting member fitted in the lead screw, a frame, mounted on the chassis, for supporting the feeding motor, and an optical pickup. The connecting member is fixed on one side of the optical pickup, and another side of the optical pickup is anchored on the guide shaft. The optical pickup is driven in a direction parallel to the guide shaft and the lead screw by the feeding motor via the connecting member. The device also includes a meshing feed member, fixed to the optical pickup or the connecting member, having a tooth in mesh engagement with a screw portion of the lead screw.
