Abstract
A compact disc player is disclosed, in which in order to protect a disc from being dirtied and damaged upon unloading and loading, at least a pair of rollers for holding therebetween and transporting a disc inserted thereinto are each formed to be of such a taper-shape that the diameter of each roller is made small at the central portion thereof and is gradually increased therefrom to both side portions thereof, thus each roller being in contact only with the peripheral edge portion of the inserted disc.
