Abstract
An electrostatic discharge protection device for an optical disc drive is provided. A rail disposed on the casing of the disc drive has an opening. A guide bar is slidable disposed on the rail. A conductive elastic plate is fixed around the opening on the rail. The elastic plate has an elastic-pressing end leaning against the guide bar through the opening, and a protrusion electrically contacting the casing. A tray supported by the guide bar to move in and out of the casing has an underside covered by a protection bottom plate. A conductive strip-shaped elastic element is fixed on the tray by a fixing screw, which fastens the protection bottom plate on the tray. As such, the elastic element is in contact with the protection bottom plate; besides, the elastic element also leans against the guide bar, so as to dissipate electrostatic discharge by the guide bar.
