Claims

[Scope of utility model registration request]

A first arm made of a non-magnetic material having three square grooves at equal pitches at the tip and a female thread near the other end; and three arms arranged so as to be fixed to the square grooves and generate a demagnetizing magnetic field. A first erase head made of a permanent magnet and a first height setting shaft provided with a male screw that engages with the female screw are rotatably held, and the first arm is horizontally held and slidable in the vertical direction. A first erase unit has the same structure as the first erase unit and a first holder attached thereto, and by deforming its arm, the position of the erase head is aligned with the first erase head. A plurality of erase unit groups installed in multiple stages at the same position and at predetermined intervals in the height direction, and each holder of the first erase unit and the erase unit group are fixed to the upper surface, and the control motor is connected to the drive source. A degaussing device comprising: a uniaxial table that moves in a straight line;
