Claims

[Scope of Claim for Utility Model Registration] 1. A cassette case in which a recording/reproducing disk is rotatably housed, head operation holes formed at corresponding positions in the center of both sides of the cassette case, and a bent portion thereof. is a shutter member having a fitting portion fitted into an edge of the cassette case, the shutter member being movable in both directions along the edge, and further extending from the fitting portion to the cassette case at a central position of the shutter member. A disk cassette comprising: a shutter member having two shutter plates for covering the head operation hole on both sides of the disc cassette; and a spring for biasing the shutter member from both sides toward the central position. 2. A utility model registration claim, wherein the spring includes two springs provided on both sides of the shutter member, and each spring applies a spring force to the shutter member from both sides in mutually opposing directions. The disk cassette described in item 1. 3. The disk cassette according to claim 1 or 2, which is provided in the case and includes a stopper for preventing movement of the shutter member in the direction in which the spring force of the spring acts.
