Abstract

A disc floating device, wherein the clamper part (50) can move in a direction perpendicular to the inserting direction of the disc (1), and can be lifted after abutting against the inserted disc (1). Taken out from the disc insertion path, the cross arm assembly (5) of the pick-up (10) rotatably arranges the turntable (4) at the reproduction standby position and the reproduction position.

Description

technical field [0001] The present invention relates to a disc floating device capable of recording and reproducing disc-shaped recording media such as CDs and DVDs (hereinafter simply referred to as discs). Background technique [0002] Figure 7 and Figure 8 is a side sectional view showing a conventional disk floating device. Figure 7 Indicates the state in the middle of inserting the disk 1 into a conventional disk floating device, Figure 8 Shows a state where the disk 1 is held on a conventional disk floating device. [0003] Such as Figure 7 As shown, in the conventional disk floating device, the disk 1 inserted into the device is guided into the device by the rotation of the roller 18 . On the roller 18, there is provided a coil spring 21, which is an urging device, which is in pressure contact with the lower surface of the inserted disc 1 . The disk 1 introduced into the device is arranged on the turntable 19 and held by the holder 16 so as to be rotatable. T...
