Claims

[Claim for Utility Model Registration] A disk-shaped recording medium is rotatably housed in a cartridge consisting of upper and lower halves, and a slider is interposed between the upper and lower halves and configured to be slidable along one edge of the cartridge. In a disk cartridge configured to open and close an opening formed in the upper and lower halves with a roughly U-shaped shutter attached to the slider, one end surface of the slider in the sliding direction is provided with an opening between the shutters. At least two of the U-shaped inner surfaces formed by the three right-angled inner surfaces are provided with an open notch, and the L-shaped one arm of the torsion spring provided in the cartridge is A disk cartridge, characterized in that the bent tip is brought into contact with the notch to urge the shutter to slide in the direction of closing the lid via the slider.
