Summary:PURPOSE: To make a disk cartridge easy to be loaded and to hold a shutter in a closed state until a lid is closed. CONSTITUTION: A shutter opening/closing member 2 is integrated with a connection member 4 through a shaft penetrating a horizontal guide hole of a supporting plate 1, and is slidably supported by the supporting plate 1. A projection part 2a engaged with a hole for opening/closing the shutter of the disk cartridge 12 is provided on a tip of a leaf spring provided on the shutter opening/closing member 2. A lock release pawl 3 is slidably supported by the supporting plate 1 together with the connection member 5 similarly. A tensile coil spring 6 is hung between the connection members 4 and 5, and the connection members 4 and 5 are energized so as to come close the each other. A slide member 8 is slidably supported by the supporting plate 1 through a guide groove, and is connected with the cap 10a of a case main body 10 through a link 9. Thus, when the cap 10a is opened/closed, the slide member 8 is reciprocally moved along the guide groove, and drives the shutter opening/closing member 2 and the lock release pawl 3 successively.
