Claims

[Scope of utility model registration request]

A frame having a pair of guide grooves arranged in a predetermined direction, a drive shaft supported at a position approximately midway between the pair of guide grooves of the frame and integrally rotating a floppy disk in a predetermined direction; It has a cam body that is coaxially and separately rotatably supported and rotationally driven, a pair of guide members, and a head provided at a position substantially corresponding to one of the guide members, and the head is provided at a position substantially corresponding to one of the guide members, and The two guide members are arranged to be guided and fitted into the pair of guide grooves, and the other guide member is guided in contact with the nuclear force body, so that it slides and comes into contact with the rotating floppy disk. A floppy disk device comprising: a carriage that causes a magnetic head that comes into contact with it to travel gradually in a radial direction to perform recording or reproduction; and a spring means that causes the other guide member to come into contact with the cam body.
