A carrying mechanism to optical pickup of a traverse of optical disc apparatus, comprises: four bar holders, connected to a traverse; two sliding bars, which each with its both ends is connectedly inserted into a receiving chamber of two opposite bar holders respectively; and an optical pickup head which both lateral ends are connectedly sleeved on one said sliding bar respectively and which is moveable back and froth on said sliding bar; wherein said bar holder is integrally formed and provided with a elastic support capably against said sliding bar. Therefore, the bar holder of the invention, with less working parts for the cost capably reduced, with the assembly more easily made and with the precision demanded to working parts not too high, may promote the level of the product used.

1. Field of the Invention
The present invention relates to an optical disc apparatus, and more particularly to a carrying mechanism to optical pickup of a traverse of optical disc apparatus.
2. Description of Related Art
The invention is description in detail with reference to the following drawings, wherein like numerals represent like elements:
FIG. 1 is an illustrated drawing to show the structure of a conventional traverse of optical disc apparatus.
FIG. 2 is a cross-sectional drawing of a adjustable bar holder of the conventional traverse of optical disc apparatus illustrated on FIG. 1.
Referring to FIG. 3, a traverse 30 of the invention is provided with four bar holders 40. An optical pickup head 32 is installed with which both lateral ends are connectedly sleeved on one sliding bar 33 respectively, and each said sliding bar 33 is installed with which both ends are connectedly sleeved on two opposite bar holders 40 respectively.
Referring to FIG. 4 and FIG. 5, each said bar holder 40 is integrally formed which top is provided with an elastic support 41. A receiving chamber 42 is formed under said elastic support 41 and a recess 43 passed through said receiving chamber 42 is formed at front end of said bar holder 40. Therefore, both ends of said sliding bar 33 are freely inserted through said recess 43 into said receiving chamber 42 of said bar holder 40 shown as FIG. 5.
Each said bar holder 40 are secured on said traverse 30 with a fixing screw 44. An adjustable screw 45 used to adjust the height of said sliding bar 33 is screwed through said traverse 30 into said receiving chamber 42 of said bar holder 40 and against said sliding bar 33 to keep an optical pickup 31 with proper parallelism and distance to a turning table 34 shown as FIG. 3.
