Patent ID: 6993776

Claim:
A disc centering device for a disc player, comprising: a pair of disc sensors capable of being pivoted, each disc sensor having a small-size disc stopper associated therewith; a small-size disc inserted through a disc insertion slot and brought into contact with said small-size disc stoppers with the periphery of said small-size disc pushing apart one end of the disc sensors, said small-size disc being thus clamped between a turntable and a damper of the disc player while being positioned; a large-size disc inserted, in place of said small-size disc, through the disc insertion slot, causing the small-size disc stoppers to retreat from a large-size disc transport path so that said large-size disc is brought into contact with large-size disc stoppers and clamped between the turntable and the clamper of the disc player while being positioned; and a disc guide member, said disc guide member being provided with a pair of guide portions, wherein: said small-size disc stoppers are provided on the other end of said disc sensors, and the insertion of said large-size disc causes the disc sensors to be pivoted to a much greater extent than with the insertion of said small-size disc, and slide over the respective guide portions, thereby causing retreat of both of said small-size disc stoppers from the large-size disc transport path.
