Problems solved by technology
Both structures have the problem of contact between the data surface of the disk and the roller or slider, which will inevitably cause contamination of the data surface; moreover, the existing suction movement cannot increase the door for the disk to enter and exit, and the next best thing is to The brush added at the entrance of the disk cannot prevent foreign matter from entering or directly judge whether there is a disk inside, which may cause misoperation of inserting the second disk; the structure of the above movements is very complicated, the parts require high precision, and the assembly process is also difficult. Relatively complicated, resulting in high final cost and cannot be widely used
In addition, the above movement does not have a manual ejection device, and the disc cannot be removed when the power is turned off.

Embodiment Construction
[0016] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings:
[0017] as attached Figure 1-29 As shown, the solution disclosed in this embodiment is mainly composed of the main support 1, the main support cover 2, the disk pressing mechanism 5, the disk rotation reading mechanism 3, the disk transmission mechanism 4, the power transmission mechanism 5 and the manual ejection mechanism. The organization consists of 6. Wherein, the disk transmission mechanism 4 is installed between the main bracket 1 and the main bracket cover 2 ; the disk rotation reading mechanism 3 and the power transmission mechanism 5 are installed on the main bracket 1 . The laser head 34 used in the disc rotation reading mechanism 3 is an existing product, and will not be described in detail if it is not used in this embodiment. ...

A mechanical core consists of master support, cover of master support, pressing mechanism of disc, disc rotary-fetching mechanism set on master support, disc transmission mechanism and power transmission mechanism driving disc transmission mechanism to move. It is featured as forming said disc transmission mechanism by movement-control sliding block connected with power transmission mechanism, left and right back arms erected symmetrically at left and right sides of disc pressing mechanism as well as left and right front arms actively connected with said left and right back arms through shaftpin.
Description
technical field [0001] The invention relates to a device for reading and writing information of a single disc, in particular to a disc transmission mechanism—a core which can effectively protect the disc, has a simple structure and can be installed at any angle. Background technique [0002] Due to the characteristics of high-density and all-digital recording, the disc has become the main data recording medium, and is widely used in CD, CD-ROM, VCD, DVD, LD and MD disc players, and has become increasingly popular in people in life. From the movement mode of the disk, the existing single-disk disk machine mainly includes the traditional horizontal movement and the suction movement that has appeared in recent years. The traditional horizontal movement transmits the disk through a tray, and the cost is low, but the disk can only be used in the horizontal position, and the improved one can only be used in the vertical direction. Existing inhalation-type cores are inhalation an...
