An opening and closing device of a rotating cage type jukebox disc tray, comprising a disc tray (2), a mounting central spindle (3) and a jukebox manipulator (5). One end of the disc tray (2) is mounted on the mounting central spindle (3) and the other end of the disc tray (2) carries compact discs (11); a positioning structure is arranged on a mating surface between the disc tray (2) and the mounting central spindle (3); the mounting central spindle (3) is mounted on the excircle of a jukebox rotating cage (4) and is parallel to the rotating central spindle (1) of the jukebox rotating cage (4); the jukebox manipulator (5) is mounted on a manipulator driving device (12); the manipulator driving device (12) is moved in a direction parallel to the geometrical axis of the rotating central spindle (1); a compact disc drive (13) is arranged by the side of the manipulator driving device (12); the jukebox manipulator (5) is provided thereon with a driving plate mechanism (6); a driving lever (7) is mounted on the disc tray (2); when the jukebox rotating cage (4) rotates in a designated direction, the disc tray (2) can revolve around the rotating central spindle (1) of the jukebox rotating cage (4) and also rotate around the mounting central spindle (3); and with the help of an in-place blocking post (10) arranged by the side of the jukebox rotating cage (4), the positioning structure can rotate and position the disc tray (2) at a fixed stop angle. The box opening and closing speeds are increased and the positioning precision is improved. |
