  • Patent number: 7650988
    Abstract: A case allows a disc to be inserted and removed smoothly without the case being opened, and also inhibits the accumulation of dust on the disc. The case has a movable holder and a fixed holder arranged inside, both of which individually define a circular arc. The movable holder is rotatable about its middle, and the rear of the fixed holder is fixed to the case so that the front portion of the fixed holder can flex. With the lever on the movable holder moved towards the bottom of the case so that the movable holder is rotated towards the front opening, a disc can be stored by inserting it through the front opening and causing the movable holder to rotate backwards and the front portion of the fixed holder to flex away.
