  • Patent number: 10141019
    Abstract: An optical disc drive (ODD) including a housing, a tray, a panel, a first linkage, and a second linkage is provided. The tray is movably disposed at the housing to move into or move out of the housing. The panel is connected to the tray and located at a side of the housing. The first linkage is rotatably disposed on the panel and located between the housing and the panel. The second linkage is rotatably disposed on the panel and located between the first linkage and the panel. By rotating the first linkage with respect to the panel in a first rotating direction, the second linkage is pushed by the first linkage and rotates with respect to the panel in a second rotating direction opposite to the first rotating direction so as to actuate the tray to move out of the housing.
