Abstract

A disc player for reading out and reproducing information signals recorded on an information disc, such as an optical disc, and displaying the read out and reproduced information signals on a display section, and a loading device for loading an information disc, such as an optical disc, or a disc table, in which both a disc proper and a disc cartridge comprised of a disc and a cartridge accommodating such disc may be loaded on the disc table. The disc player enables the information on the disc to be read out and reproduced and the readout and reproducing information to be displayed as a visual information, and is reduced in size so as to be portable. The loading device enables both the disc cartridge and the disc proper to be loaded on the disc player.
