Abstract: A disc is inserted into a disc reproducing apparatus by insertion of a casing housing the disc therein and is removed from the apparatus by insertion of an empty casing thereinto. The apparatus comprises a cartridge which has a stylus and a first mechanism for driving the cartridge. The first driving mechanism includes a clutch mechanism which transmits the driving force of a motor to the cartridge when the apparatus is in a reproducing condition, and which does not transmit the driving force to the cartridge to render the cartridge free to move when the apparatus is in a nonreproducing condition, and an engaging mechanism for holding the cartridge at a reproduction start position in the nonreproducing condition.
