Claims

[Claims for Utility Model Registration] (1) An opening for reading or writing a signal is formed in a cartridge storing a disk, and the cartridge is attached to the top, bottom and front side of the cartridge to open the opening. An engagement hole is provided in the shutter of the disk cartridge equipped with a shutter that opens and closes from a part of the front wall of the shutter to the bottom plate, and the engagement hole is provided opposite to the insertion direction of the disk cartridge. A shutter opening/closing mechanism for a disk cartridge, which is provided with a shutter opening/closing arm having a protrusion that engages with the hole and being rotated by being pressed by the disk cartridge, the mechanism braking the rotation of the shutter opening/closing arm. A shutter opening/closing mechanism for a disc cartridge characterized by being provided with a damper means. (2) The disc cartridge according to claim 1, wherein the damper means is a damper means in which the braking force is greater when the disc cartridge is ejected than when the disc cartridge is inserted. Shutter opening/closing mechanism.
