Abstract:
1. An electrostatic discharge protection device for an optical disk drive, comprising: a tray, wherein electric components are disposed on the tray, and the bottom of the tray is covered by a conductive traverse cover; two rails being made of conductive material and supporting the tray so as to allow the two sides of the tray to be slid thereon; at least an elastic stopper being made of conductive material and being electrically connected to the traverse cover and at least one of the rails; and a case made of conductive material that is grounded, wherein each two inner sides of the case has a guide respectively so as to allow the two rails to be slid thereon, the guides are made of plastic material, the rails are electrically connected to the elastic stopper slide thereon, and each guide comprises a conductive sponge disposed therein, one end of the conductive sponge contacting the case, and another end of the conductive sponge that protrudes from the guide contacting the rail.
