ABSTRACT:
A disc player has a compact disc spindle assembly, mini-disc spindle assembly, and a pickup device on its base plate. A compact disc tray is connected with the base plate and a mini-disc tray is connected with the compact disc tray, respectively in a horizontally and vertically movable state. The disc player has a moving plate for driving the base plate and the compact disc tray. A mini-disc tray conveying device having a rack plate, a transfer gear, etc., is positioned between the compact disc tray and the mini-disc tray provided therein. Rack gears are formed on two opposite side walls of the mini-disc tray and the rack plate, and between the rack gears the transfer gear is interposed into which the fixed shaft projected upward from the lower surface of the compact disc tray is inserted. Thus, in loading a mini-disc cartridge or compact disc, the compact disc tray can be transferred horizontally together with the mini-disc tray provided therein. The transfer gear has a smaller first gear engaged with the rack gear on the side wall of rack plate, and a larger second gear engaged with the rack gear formed on the side wall of the mini-disc tray, whereby the mini-disc tray is transferred at a higher speed than a transfer speed of the compact disc tray in a loading or unloading operation.
