Claims

[Scope of utility model registration request]

In a micro floppy disk air cleaning device for a floppy disk drive with a built-in air tube, a magnet with a soft cover is fixed to the top surface of a rotor that rotates a flexible magnetic disk. An air blowing hole is provided in the air pipe at a position where the chucking of the flexible magnetic disk having a hub and the rotational drive of the rotor are transmitted to the flexible magnetic disk, and the air blowing direction is the same as the direction in which the flexible magnetic disk rotates. An air cleaning device for a micro floppy disk, characterized in that the flexible magnetic disk is rotated and air is blown from a head window of the micro floppy disk into a gap between an upper shell and a lower shell.
