Claims

[Scope of utility model registration request]

A head for recording and reproducing information on the floppy disk, in which a set arm that rotatably holds the center of the floppy disk is movable between a holding position and a non-holding position by rotating a clamp lever. is arranged so as to be able to move toward and away from the floppy disk, and when the floppy disk is inserted, it is moved to the back and held in the first locked state where it is locked to the main body of the device, and the set arm is moved toward the holding position. As a result of the movement, the first locking state is released and the floppy disk is locked to the set arm, and is held in a second locking state in which it does not contact the floppy disk, and as the set arm moves toward the non-holding position, the second locking state is released. An eject plate is disposed for releasing the stopped state and pushing out the floppy disk to the outside,
A floppy disk drive device comprising an eject spring that urges the eject plate in the extrusion direction and the locking direction simultaneously.
