Abstract:
1. An optical pickup transferring apparatus including a lead screw having an external thread, a slider coupled with a optical pickup to convert a rotation of the lead screw into rectilinear motion so as to rectilinearly shift the optical pickup in the direction of the radius of the optical disk, wherein the slider comprises: a base; a floating portion elastically coupled to the base and having on one side thereof at least one protuberance inserted into the external thread of the lead screw; and an elastic element; located on the top of the base and the floating portion, having a first elastic portion to push the floating portion toward the lead screw so that the protuberance is inserted into the external thread, and a second elastic portion, having an L shape, to push the floating portion toward the external thread to prevent the protuberance from escaping from the external thread, the L-shape comprising a first leg extending parallel to a direction of a pushing force of the second elastic portion on the floating portion and a second leg bent relative to the first leg and extending perpendicular to a direction of the pushing force of the second elastic portion on the floating portion.
