Claims

[Scope of utility model registration request]

a carrier that removably receives a floppy disk cartridge in which a floppy disk media is rotatably housed and a shutter for opening and closing the read/write opening is slidably provided in an energized state; a lock lever which holds a slide plate for switching the carrier between loading and non-loading states in a non-loading position and releases the holding state upon insertion of a cartridge; In the cartridge attachment/detachment mechanism of a micro floppy disk drive that includes a shutter opening/closing lever that opens, the shutter opening/closing lever passes through an opening groove provided in the carrier for engaging with the shutter of the cartridge, and the shutter opening/closing lever passes through an opening groove provided in the carrier for engaging with the shutter of the cartridge. The shutter opening/closing lever engages with a concave groove of the cartridge, and both ends of the opening groove of the carrier are closed, and when the cartridge is incorrectly inserted, the shutter opening/closing lever engages with the opening of the carrier before the cartridge releases the locking lever. A cartridge attachment/detachment mechanism for a micro floppy disk drive characterized in that the cartridge comes into contact with the other end of the groove to prevent further insertion of the cartridge, thereby preventing incorrect insertion.
