A baggage management gate includes a first reading device and a second reading device, a detecting device, a determining unit, a first opening and closing device and a second opening and closing device. The baggage management gate manages baggage that is restricted to be carried in or out from a predetermined region. And in order away from the region in which the baggage is managed, the first reading device, the second opening and closing device, the detecting device for both the first person and the second person, the first opening and closing device, and the second reading device are arranged in an entrance direction from the passage to the management region in which the baggage is managed.
摘要:
A recording medium detecting system includes a magnetic field-generating unit that generates an alternating magnetic field in a predetermined particular region, a detecting unit provided close to the particular region, that detects a change in magnetic flux density not smaller than a predetermined magnetic-flux-density difference B2, and a recording medium, containing multiple magnetic wires made of a magnetic material and formed in a wire shape having a predetermined length, that causes a large Barkhausen effect when the alternating magnetic field is applied. A magnetic-flux-density difference B1 detected by the detecting unit at an installation position thereof when the recording medium is placed in the particular region is not smaller than the magnetic-flux-density difference B2.
摘要:
A sheet body including plural magnetic wires arranged and embedded along a longitudinal direction of the sheet body at a predetermined interval, wherein each of the magnetic wires is formed by two kinds of magnetic bodies with different coercive forces into a linear shape of a predetermined length, and the magnetic wire column with stronger coercive force is magnetized, thereby preventing the magnetic wire column with weaker coercive force from generating a response signal to an alternating magnetic field.

A magnetic wire includes a magnetic metal wire material having a surface coated with a layer of an insulating material. The magnetic wire has a magnetic coercive force of 30 A/m or less and has a Barkhausen effect.
摘要:
An information reading device for reading identification information from a medium to which at least one magnetic element for generating a signal upon receiving a magnetic field is provided, which includes a plurality of detecting parts that detect a signal generated from the magnetic element according to the magnetic field applied to the medium, and an information reading part that reads information formed by the magnetic element based on a combination of detecting parts which have detected the generated signal.
摘要:
A scanned medium including: a sheet substrate; and a line-shaped magnetic body formed inside the sheet substrate, wherein the magnetic properties of the magnetic body are detected inside a magnetic field formed by a scanning apparatus, and the magnetic body has at least a portion thereof formed so as to have the same directional component as that of the magnetic field, regardless of the direction in which the sheet substrate is positioned.
