Claims

[Claims for Utility Model Registration] (1) A carriage carrying a pick-up means is guided and driven by a guide drive means along both recording surfaces of a disk placed on a turntable to perform both sides of the disk. In the double-sided disc player, the guide means includes first and second guide mechanisms disposed on both sides of the disc carrying surface of the turntable to support the carriage so that it can be engaged and disengaged at a predetermined engagement and disengagement position. , a gripping member capable of gripping the carriage in the predetermined engagement/disengagement position; a conveying mechanism for conveying along a plane intersecting the guiding direction; and a driving means for moving the carriage on the first and second guide mechanisms and driving the conveying mechanism to convey the gripping member. The conveying mechanism includes a rotating member that is rotatably provided in the plane and supports the gripping member, a sun gear that is provided coaxially with the rotational axis of the rotating member, and a sun gear that is provided on the carriage and supports the holding member. It has a planetary gear that can mesh with the gear, and a detachment regulating member is provided on the outer periphery of the sun gear to make sliding contact with the planetary gear and regulate detachment of the planetary gear from the sun gear. A double-sided disc player. (2) The withdrawal regulating member is provided around the central axis of the sun gear within a predetermined angular range, and at both ends of the withdrawal regulating member there is a direction in which the withdrawal regulating member approaches the sun gear from one end toward the other end. 2. A double-sided disc player according to claim 1, further comprising a tapered surface that guides said planetary gear at an angle.
