Problems solved by technology

[0005] In the prior art, guide shafts 6, 6' are used at both ends of the pickup 6 to support and move the pickup base 1 respectively; , which increases the overall accessory count for the optical drive and complicates the installation process
[0006] Especially in the prior art, due to the relatively large number of components of the optical disc drive, the incidence of defective phenomena due to installation tolerances increases, and in use, it is necessary to rely on external forces to change the setting state of the guide shafts 6, 6' , which degrades operational reliability

Abstract

The invention discloses a picker guidance structure, which comprises the following parts: picker chassis (30) with pickup window (32), optical picker (34), guidance flute (37c) and projection groove (41r), wherein the optical picker (34) is supported by mould structure to move; the mould structure is set on the pickup window (32); at least one end of mould structure integrates the picker chassis (30); the guidance flute (37c) and projection groove (41r) are set on the ends of mould structure and optical picker separately, which proceed moving guidance. The structure minimizes the element quantity of disk driver as well as the setting state, which improves the operational reliability.

Description

【Technical Field】 [0001] The present invention relates to an optical disc drive, and more specifically, it relates to an optical pickup guide structure for transporting an optical pickup that performs signal recording and reading operations on an optical disc. 【Background technique】 [0002] Fig. 1 is a plan view of the structure of a conventional optical disc drive. As shown in the figure, a spindle motor 2 for rotating a magnetic disk D is provided on a pickup base 1 provided on a main chassis (not shown), and a turntable 3 on which the magnetic disk D is placed is provided on the spindle motor 2. [0003] The optical pickup 5 responsible for signal recording or signal reading on the signal recording surface of the optical disc is supported on a pair of guide shafts 6, 6'arranged in parallel on the pickup base 1, and the optical pickup 5 can The guide shaft moves in the radial direction of the optical disc. A fixed guide rod 7 is provided on one side of the optical pickup 5, an...
