Claims (1)

[Claims for Utility Model Registration] (1) A carriage holding an optical pickup means is guided and driven by a guide drive means along both recording surfaces of a disk placed on a turntable, and said optical pickup means A double-sided optical disc player that performs double-sided play on the disc by turning on the power or transmitting an electric signal through wiring means connected to the turntable, wherein the guide drive means are arranged on both sides of the disc gripping surface of the turntable. first and second guide mechanisms that grip the carriage so that the carriage can be engaged and disengaged at a predetermined engagement and disengagement position; a gripping member that can grasp the carriage in the predetermined engagement and disengagement position; a conveying mechanism that transports the first and second guide mechanisms from an engagement/disengagement position to the other engagement/disengagement position along a plane intersecting the guiding direction of the guide mechanism; and the first and second guide mechanisms. a driving means for moving the carriage at the top and driving the transport mechanism to transport the gripping member; The wiring means includes a first flexible part arranged to be flexible in a plane perpendicular to the rotational axis of the rotating member, and a first flexible part arranged to be flexible in a plane parallel to the rotational axis of the rotational member, and a first flexible part arranged to be flexible in a plane parallel to the rotational axis of the rotational member. a second flexible part connected to a pickup means, and a flexible base plate engaged with the rotating member. (2) A double-sided performance device according to claim 1, further comprising a winding and feeding means provided on the rotating member and winding and feeding the second flexible portion in accordance with movement of the carriage. optical disc player. (3) The winding and sending means includes a first arm member that is attached to the rotating member in a cantilevered manner and slidably holds the second flexible portion at its tip, and the first arm member. a second arm member that is attached to a distal end portion of the arm member so as to be swingable between a winding position and a sending position and having a free end portion slidably holding the second flexible portion, and the second arm member; 3. The double-sided playable optical disc player according to claim 2, further comprising a biasing means for biasing the disc toward the winding position.
