ABSTRACT:
Disclosed is an elevating apparatus of a spindle assembly of a disc player for adjusting height of the spindle assembly to rotate a minidisc and a compact disc which are mounted on a minidisc tray and a compact disc tray, respectively. The spindle assembly having a turntable for rotating the disc mounted on the tray is secured thereto to reciprocate vertically in a first direction. The elevating apparatus is secured to a lower portion of the base plate to reciprocate in a horizontal direction of a second direction perpendicular to the first direction thereby to move vertically the spindle assembly. An actuation apparatus is provided thereon to move backwards and forwards the elevating apparatus. In the compact and minidisc player capable of selective reproduction operation, height difference between a minidisc mounting surface and a compact disc mounting surface can be compensated.
