Claims

[Scope of utility model registration request]

A double-sided performance disc player that performs playing on both sides of the disc by guiding and driving a carriage carrying a pick-up means along both recording surfaces of a disc placed on a turntable by a guiding driving means, the guiding driving means The means includes first and second guide mechanisms disposed on both sides of the disk supporting surface of the turntable to support the carriage so that it can be engaged and disengaged at a predetermined engagement and disengagement position, and a means for displacing the carriage in the predetermined engagement and disengagement position. a gripping member capable of gripping the same, and transporting the gripping member from an engagement/disengagement position of one of the first and second guide mechanisms to an engagement/disengagement position of the other along a plane intersecting the guiding direction of the guide mechanism. and a driving means for moving the carriage on the first and second guide mechanisms and driving the transport mechanism to transport the gripping member, and the driving means moves in the guiding direction. A pair of rack members provided in parallel, a gear rotatably supported on the carriage and capable of meshing with each of the rack members, and a drive source provided on the carriage and applying torque to the gear. and at least a portion of the pair of rack members is movable from a rest position in a direction away from the transport mechanism in response to a force of a predetermined magnitude or more;
The conveying mechanism includes a rotary member that is rotatably provided within the plane and grips the gripping member, a sun gear that is provided coaxially with the rotation axis of the rotary member, and a sun gear that is provided on the carriage and that is attached to the sun gear. 2. A double-sided disc player comprising a planetary gear that can mesh with the sun gear, at least a portion of the sun gear being movable with a predetermined amount of force in the direction of movement of the gripping member.
