Abstract:
1. A springing device disposed in an optical disc drive, wherein the optical disc drive comprises at least a casing, a tray and a baffler, the casing having an aperture, the tray moveably disposed in the casing and selectively driven for carrying an optical disc into or out of the casing through the aperture, the baffler disposed in the casing for opening or closing the aperture, the springing device comprising: a moveable piece having a first end and a second end, the first end of the moveable piece pivotally connected to an inner wall of the casing and the pivotal connection thereof used as a supporting point for the moveable piece to swing, the second end pivotally connected to the baffler; and an elastic object having a third end, a fourth end and a bow portion passing round the supporting point, the third end of the elastic object connected to the moveable piece, and the fourth end of the elastic object fixed at the casing; wherein when the tray is disposed within the optical disc drive, the moveable piece and the baffler are biased by the elastic object so that the baffler closes the aperture; and when the tray is driven to move towards the aperture and touch the moveable piece, the second end of the moveable piece is swung to move the baffler, so that the baffler opens the aperture, and a restoring force is provided by the elastic object for causing the moveable piece to swing back and the baffler to close the aperture.
