  • Disc rack with holders which rest in a different position when unloaded than when loaded
    Patent number: 5232275
    Abstract: A disc rack capable of supporting holder members for holding a disc in such a way that the holder members are turnable about a supporting rod (3) from a drawn-out position to a retracted position and vice versa, including a positioning member able to come into contact with a circumferential portion of a disc loaded in a holder member when the holder member, is put in the retracted position, to keep the holder member loaded with the disc at a rotation angle different from that of a holder member (1) not loaded with a disc. This disc rack makes it possible to easily confirm whether or not the holder member is loaded with a disc without providing an additional indicator.
