Description of the invention: [Technical field to which the invention pertains] The present invention relates to an optical disk drive, especially an electrostatic protector, to prevent damage to precision electronic components. [Prior Art] Since the optical disk drive contains relatively precise electronic components, Operation over avoiding & : The user must touch the CD player 'so the static jj on the body: 2 2 ' or the electronic parts that are stalking through the conductors in the CD player are extremely vulnerable. As shown in FIG. 1 and FIG. 2, the moon is a conventional optical disc showing the inner and the back, wherein the metal casing 11 has a hollow region, and the fixed sliding grooves of the plastic material are fixed on both sides. Each of the guide rails 112 for arranging a metal material slides, the end of the guide rail 112 is blocked by the block 113 on the casing u, and the other end supports the slide bar d of the tray 12 from both sides, and is recessed in a guide rail 112. The hook U4, in order to block the stopper 122 at the rear end of the tray 12, restricts the distance of the tray 12 from the outside of the casing 11, so that the plastic material tray 12 can slide into and out of the casing 11 and completely extend out of the casing 1 . The precision electronic components such as the main shaft motor 13 and the read head 14 of the rotating disc are disposed on the tray 12, and the lower portion is covered with a metal protective bottom plate 15. The front end of the tray 12 is adjacent to a panel 16 , and the panel 16 is provided with an exit button 7 . The end of the flexible printed circuit board 18 is connected to the main circuit board 19 and is attached to the inner surface of the casing 11 and the other end. Then, it is movable and connected to the rear end of the tray 12, and is electrically connected to the bottom plate 15, and one of the lines of the flexible cable μ is grounded to the casing 11. When the user presses the eject button 17 to eject the film, the static electricity carried by the gap between the panel 16 and the eject button 17 is transmitted to the metal protection substrate 15, or directly touches the disc player 10, and is directly transmitted to the metal protection substrate 1329865

The static cable 18' is then used to ground the static electricity to the casing 11. However, the flexible cable 18 has a small line, although it can eliminate a small amount of static electricity, but for a sudden large amount of static electricity, it cannot be quickly eliminated, and static electricity is accumulated to cause damage. In addition, the flexible cable 18 is mainly used for the transmission of signals and data. 1 A large amount of static electricity passes through the flexible cable 18, which easily interferes with the signals and data of the simultaneous transmission, and affects the reliability of the optical disk signal. Moreover, when the hook 114 recessed by the metal sheet-formed guide rail 112 is stuck against the stopper 122 of the plastic material, especially when subjected to a large impact, the stopper e is often damaged, and the tray and the slide rail are stuck. The tray cannot be moved in and out normally. Therefore, the conventional optical disc drive has problems in the electrostatic protection device and the brake of the tray, and there is still a problem to be solved.
