Abstract
An auto loading disc player including a housing having a slot to receive a disc therein, a player mechanism disposed in the housing, and a disc carrier mechanism for conveying the disc close to a playing position. A pair of guides is disposed bilaterally of a carrier path for the disc for guiding the disc along the carrier path. A disc diameter discriminator mechanism engages with the periphery of the disc to discriminate between diameters of discs at the same time that the guide means guides the disc. The disc diameter discriminator mechanism includes a structure for driving the guides in such a manner that the distance between said guides corresponds to the outer diameter of the disc. The guides engage with the periphery of the disc during its conveyance to thus cause the disc to cooperate with the disc carrier mechanism for guiding the disc. The disc carrier mechanism releases the disc from engagement with the guides during the period of time when the disc is being played.
