Claims

[Scope of utility model registration request]

A reproducing element drive mechanism that transports the reproducing element in the radial direction of the disc, a disc elevating mechanism that raises and lowers the disc with respect to the turntable, and a disc lifting mechanism that controls tracking of the reproducing element and moves the reproducing element at a predetermined speed during disc reproduction. a tracking error signal for moving the disc at a speed other than the predetermined speed, a high-speed feed signal for displacing the reproducing element at a higher speed than the predetermined speed other than when playing the disc, and a drive signal for moving the disc up and down. A control circuit supplies power to one drive motor, and selectively switches the reproduction element drive mechanism and the disk lifting mechanism to the drive motor in response to a signal supplied to the drive motor by the control circuit. A disc-shaped information recording medium reproducing device comprising a switching mechanism that connects the disc-shaped information recording medium.
