Abstract

The invention relates to a CD (Compact Disc) driver, which comprises a frame, a tray, a movable member and a buffer portion, wherein the tray is slidably arranged on the frame and comprises a sliding slot; the movable member comprises a protruding portion, and the protruding portion is slidably located in the sliding slot; and the buffer portion is configured close to one end of the sliding slot. In the disc withdrawing process of the CD driver, the protruding portion is contacted with the buffer portion so as to enable the tray to slow down.

Description

technical field [0001] The present invention relates to an optical drive, and in particular to an optical drive with a buffer. Background technique [0002] In the final stroke of the ejection of the tray of the traditional optical drive, the ejection speed of the tray is usually slowed down, so as to prevent the tray from violently hitting the rack and easily causing the disc in the tray to fall out of the tray. Usually, an electronic switch (such as a limit switch) is configured in a traditional optical drive to realize this function. For example, when the ejection of the tray indirectly triggers the electronic switch, the motor driving the tray starts to brake to slow down the ejection of the tray to the end. However, the electronic switch will increase the cost of the optical drive and occupy a certain space in the optical drive. [0003] Therefore, there is an urgent need to propose a new solution that can slow down the ejection speed of the tray. Contents of the in...
