PURPOSE:To lift and lower a disk easily and exactly, by constituting so that a lift lever is made to rise or fall down, a lift plate is lifted or lowered, and a disk supporting body is lifted or lowered in the upper part of a platter. CONSTITUTION:A disk 4 is supported at a holding position of the upper part of a platter 2 by a disk supporting body 5 when a disk case is drawn out, and a driving wheel 8 is rotated in reverse by a prescribed angle. Therefore, any lift lever 11 falls down, and the disk supporting body 5 lowers together with a lift ring 7 and is placed at a music playing position. When a music play is ended and the disk 4 is withdrawn, as the driving wheel 8 is rotated forward, the lift lever 11 rises simultaneously, and the lift ring 7 rises, therefore, the disk supporting body 5 can push up the disk 4 to the holding position from the music playing position. In this way, the disk 4 can be lifted and lowered between the holding position and the music playing position by an extremely simple constitution, and a lifting or lowering attitude of the disk supporting body 5 is always horizontal, therefore, the disk 4 can be installed and withdrawn exactly. |
