<p>PROBLEM TO BE SOLVED: To provide an optical pickup transfer device capable of accurately adjusting the parallelism of a lead screw even if a lead screw holder is con tracted or twisted. SOLUTION: This transfer device is constituted of a base 10 on which a turntable 12 is mounted, a guide shaft 28 installed on the base 10, a lead screw 26 rotated around a horizontal shaft in which a thread 26a is formed and which is mounted onto the base 10 and is extended in parallel to the guide shaft 28, an optical pickup device 16 which is moved in the radial direction against a vertical shaft by the rotation of the lead screw 26, a driving motor 20 which is installed on the base 10, which is freely movably connected to the first end part of the lead screw 26 and which is for rotating the screw and a lead screw adjusting means which is mounted on the base 10, which holds the second end part of the lead screw 26, which is moved together with the base 10 and which is capable of adjusting the parallelism of the lead screw 26.</p> |
