<p>A disk cartridge has a rotation wheel (4) rotatably received in a cartridge body and a lock member (72) for inhibiting rotation of the rotation wheel (4). The lock member (72) has a lock section (76) engaging with an engagement recess (85) of the rotation wheel (4) to lock it at a position at which shutter plates (5a, 5b) close a first opening (24), and also has first and second lock release sections (77, 78) for releasing the lock section (76) from its engagement with the engagement recess (85). The first lock release section (77) faces an insertion guide groove (25b) in the front face of the cartridge body (2), and the second lock release member (78) faces a guide groove (15b) formed in the side face on the side from which direction the cartridge body (2) is inserted. Pressing either the first lock release section (77) or the second lock release section (78) releases lock.</p> |
