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.
In an auto loading disc player of a type including a housing having a slot to receive a disc therein, player means disposed in said housing, and drivable disc carrier means for carrying said disc close to a predetermined playing position, the improvement comprising: means defining a carrier path, a pair of drivable guide means disposed bilaterally of said carrier path for said disc for guiding said disc along said carrier path, and a disc diameter discriminator mechanism for engaging with the periphery of said disc to automatically discriminate between diameters of discs while said disc is being moved by said carrier means towards said playing position and at the same time when said guide means guides said disc, said disc diameter discriminator mechanism comprising means for driving said guide means in such a manner that a distance between said guide means corresponds to the outer diameter of said disc, said guide means engaging with the periphery of said disc during its conveyance to thus cause said disc to cooperate with said disc carrier means for guiding said disc, said disc carrier means releasing said disc from engagement with said guide means during the period of time when said disc is played.

The auto loading disc player as described in claim 1, further comprising a support shaft extending in a direction substantially perpendicular to a recording surface of said disc, said pair of guide means being pivotally supported by said support shaft, and said disc carrier means being so driven as to change angular positions of said guide means to be pivoted to opposite directions.
