に構成したことを特徴とするディスクカートリッジ。A cartridge housing in which a disc is housed, an opening provided in the cartridge housing, and a cartridge housing that is attached to the cartridge housing and arranged symmetrically to each other along a plane parallel to the disc to open and close the opening. a disk cartridge comprising: a pair of left and right shutters that are moved, and configured such that opposing edges of the pair of left and right shutters are brought into close contact with each other to close the opening; An extension piece is integrally provided on the opposite edge of one of the shutters, and this extension piece is recessed from the opposite edge of the one shutter to the inner surface of that one shutter by approximately the thickness of the external shutter. The edge on the other shutter side is formed into an inclined edge that is inclined with respect to the opposing edge, and the end of the inclined edge on the side closest to the other shutter is formed at a position away from the outer periphery of the disk. - integrally providing an inclined piece that is further inclined and protruded from the extension piece toward the inner surface of the one shutter;
When closing the opening with the pair of left and right shutters, the opposing edge of the other shutter is sequentially guided by the slanted piece and slanted edge of the one shutter to ride on the extension piece, thereby completely closing the opening. A disk cartridge characterized in that it is configured to allow.
