Abstract

An optical pickup transferring apparatus including a slider having a base, a floating portion elastically coupled to the base, the floating portion having on one side thereof at least one protuberance inserted into the external thread of a lead screw, and an elastic element located on the top of the base and the floating portion. The elastic element includes 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 to push the floating portion toward the screw groove to thereby prevent the protuberance from escaping from the external thread when the floating portion is transformed elastically.

Description

technical field [0001] The present invention relates to an optical pickup transfer device, and more particularly to an optical pickup transfer device for an optical disc drive, with an improved slider for supporting the optical pickup. Background technique [0002] Typically, an optical disc drive writes to / reads information from an optical disc, such as a compact disc (CD) and a digital versatile disc (DVD), and the drive includes an accessory chassis assembly that has a An optical pickup that receives reflected light to write or read information. [0003] figure 1 is a top view of the traditional accessory chassis assembly for an optical drive. figure 2 is in figure 1 A perspective view of the slider of a conventional accessory chassis assembly shown in . [0004] refer to figure 1 , the sub-chassis assembly 100 includes a sub-chassis 101, a turntable 110 for installing an optical disc 103 rotated by a spindle motor (not shown), an optical pickup 120 for writing / read...
