CD machine CD input/output mechanism

Abstract

The invention discloses an optical disc player advancing and retreating mechanism, which uses a conveying unit and a guiding unit to obliquely input the optical disc into the optical disc player, wherein the conveying unit includes a roller or two rollers, and the guiding unit includes two mutually symmetrical rollers. or asymmetrical cones. When the optical disc advances and retreats, the two ends of the optical disc straddle two guide units with different cone angles, or two guide units with the same cone angle but different lengths, or two cones with equal shapes but different lengths. On the guide unit attached with different roller speeds, the disc is guided to advance and retreat obliquely according to the different arc speeds at both ends of the guide unit roller, so as to avoid the problem caused by the forward advance and retreat mechanism of the traditional optical disc drive. Collision and noise also reduce the guide rail parts required by the straight forward and backward mechanism of the traditional optical disc drive to guide the optical disc to the fixed position of the optical disc in the optical disc drive.

Description

technical field [0001] The present invention relates to an optical disc drive advance and retreat device, in particular to an optical disc that advances and retreats in an oblique direction, and reduces the noise generated by the optical disc colliding with the guide rail that guides the positioning of the optical disc through the forward advance and retreat in the casing. The optical disc drive advances and unwinds the film device. Background technique [0002] With the advent of multimedia digital life, the use of notebook computers has become more and more common. For example, USB bus, IEEE 1394 bus, PCI bus, IDE ATA / ATAPI interface, as well as the wireless network card connected to it, U disk (ie flash disk) and CD player, etc., can be said to be necessary equipment. Especially now there are many types of optical storage media, such as compact discs (Compact Dick, CD), audio-visual discs (Video Compact Disk, VCD), and digital video discs (Digital Video Disk, DVD) are al...

Problems solved by technology

However, due to the limitation of the space of the optical disc drive, the optical disc 70 inserted in the center of the insertion port 90 cannot be quickly aligned with the center of the roller 91a in the direction of input into the optical disc drive, and directly reaches the optical disc fixing position 100 in the optical disc drive. It must be guided obliquely by the guide rails 80, 81 in the CD player before it can face the center of the roller 91a, and then be transported to the fixed position 100 by the roller 91.

Therefore, the optical disc 70 will collide with the guide rails 80, 81 during the advance and retreat process, which will not only cause collision noise and be easily damaged, but also easily crash the optical disc 70.

[0005] In order to improve the situation where the optical disc drive will collide after the optical disc is fed into the optical disc drive in the past, the inventor designed a design that can avoid the collision between the optical disc and the casing according to the characteristics of the internal components of the optical disc drive.
