IPC: G08B13/24
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a harmonic EAS marker having a re-approaching element which is shorter and thinner than a marker being used at present. SOLUTION: This is a harmonic electronic merchandise monitoring device, and the monitoring device including three wires 21 composed of magnetic materials arrayed in parallel is applied. The magnetic material has a magnetic hysteresis loop having large Barkhousen discontinuity, and a marker 20 is exposed to an outside magnetic field, and when the magnetic force of the same magnetic field is beyond a scheduled threshold value in a direction opposed to the instantaneous magnetic pole of the marker 20, the magnetic pole of the magnetic material is repeatedly converted. When those three wires 21 are exposed to the magnetic field, the both ends of the same wire are connected by a magnetic charge enlarging member 22 formed of a high penetrating member so that the repeated conversion of the magnetic pole can be simultaneously attained.  The harmonic marker obtained in this way can be substantially shorter than a conventionally used harmonic marker as a whole, and at the same time, a signal having amplitude equivalent to that of the conventional marker can be generated.
