<p>A disk cartridge with a case comprising upper and lower shell halves (6,7) for accommodating a disk therein and a writing protection mechanism. The writing protection mechanism comprises a movable plug (311) having a main body (312) and at least one leg (313) being flush with one sliding end surface of the main body (312). A guide part (318a,318b) has a flat wall (320a,32b) and an upright wall (320a,320b) for surrounding the plug. A projection (327) cooperates with the leg (313) of the plug. A raised portion (326) of the guide part is in contact with another sliding end surface without the leg (313) of the main body (312) when the plug is properly assembled in the guide part. If the plug is inserted incorrectly, the plug stands obliquely so that the operator can detect the insertion miss of the plug.</p> |
