    • A tag disclosed in this invention detects theft of bills, notes, or securities positioned therewith in a cash register, a safe, or the like. The capability of a tag-detecting sensor is not affected by a conductive or magnetic auxiliary member disposed between the sensor and the tag. The tag for detecting theft, which has one or more resonant circuit sections on an insulating base sheet, is positioned with an article in a specified place. An alarm is not activated when the tag is detected by the sensor, while it is activated when the tag is not detected by the sensor. At least one of the resonant circuit sections is disposed apart from the conductive or magnetic auxiliary member, with respect to the auxiliary member to be disposed between the sensor and the tag. The specified place refers to a case positioned in a cash register or a safe; the article includes bills, notes, or securities; and the auxiliary member is a metal retainer. A fold line is formed on the insulating base sheet, and the resonator circuit sections are arranged apart from the fold line on the sheet.

    • A theftproof tag which is effective regardless of the material of the article to which it is attached. There is neither a change in resonance of a resonance circuit nor a decrease in the Q value due to the material of the surface of a theft monitored article, thereby decreasing errors in the operation of a theft monitor. The theftproof tag has a resonance circuit resonating to an electric wave at a specified frequency transmitted from a transmitting antenna, and having a coil unit and a capacitor electrically connected to both ends of the coil unit. The coil unit has a magnetic core member made of a composite material composed of a powder or flakes of a soft magnetic metal, and a plastic, and a winding wound around the periphery of the magnetic core member and connected to the capacitor, a portion of the magnetic core member facing the attaching surface of the article.
    • 防盗标签,无论其附着的物品是否有效,都是有效的。 谐振电路的谐振不会发生变化,也不会由于被盗物体的表面的材料而导致的Q值的降低,从而减少了盗窃监视器的操作中的错误。 防盗标签具有谐振电路,其以从发送天线发送的特定频率的电波谐振,并且具有线圈单元和电连接到线圈单元的两端的电容器。 线圈单元具有由由软磁性金属的粉末或薄片构成的复合材料制成的磁芯构件和塑料,以及缠绕在磁芯构件周围并连接到电容器的绕组的一部分 磁芯构件面向制品的附接表面。

    • An anti-theft tag which when attached to an article containing a conductive surface properly transmits a signal to a control device to generate an alarm if the article has been taken without permission. The anti-theft tag includes a resonance circuit and a soft magnetic material disposed between an attaching face of the article and the resonance circuit. The soft magnetic material allows the anti-theft tag to provide a resonance frequency which is independent of the material the anti-theft tag is attached to. The soft magnetic material may be composed of, for example, any one of an amorphous alloy, PERMALLOY, electromagnetic soft iron, silicon steel sheet, sendust alloy, Fe--Al alloy, and soft magnetic ferrite. The soft magnetic material may also be a composite material of soft magnetic material flakes and a plastic.
    • 防盗标签当被附着到包含导电表面的物品上时,正确地将信号发送到控制装置,以在没有许可的情况下取出物品时产生警报。 防盗标签包括设置在物品的连接面和谐振电路之间的谐振电路和软磁性材料。 软磁材料允许防盗标签提供独立于防盗标签附着的材料的共振频率。 软磁性材料可以由例如非晶合金,PERMALLOY,电磁软铁,硅钢板,铁硅铝合金,Fe-Al合金和软磁铁氧体中的任一种构成。 软磁性材料也可以是软磁性薄片和塑料的复合材料。

    • A soft magnetic member (5) which is formed by a composite of an organic object such as a metal grain powder, a flake, a ferrite grain powder, a ferrite, an amorphous film or a layered member of the amorphous film with 10 mm or lower thickness so as to satisfy a predetermined relationship with an antenna area, a circumference length, and a magnetic transmission ratio and a conductive member (7) which has approximately 10×10−8 Ωm or lower, more preferably 0.005 Ω or lower initial resistance are provided between the an antenna coil which is formed at least one loop and a metal surface (6) of the conductive member such as a metal casing. The magnetic flux which invades into the conductive object is blocked by the soft magnetic member (5) and the conductive member (7) so as to restrict the influence thereof. By doing this, it is possible to provide a reader/writer antenna for an RFID system in which it is possible to restrict a variance of a resonating frequency and an increase in a loss even if it is disposed so as to contact the conductive object such as a metal casing.

    • An antenna coil includes an air-core coil wound helically in a plane and a plate magnetic core member inserted in the air-core coil to be approximately parallel with a plane of the air-core coil. The magnetic core member is formed by a soft magnetic metal, an amorphous or ferrite, or a composite member of a powder, flake and plastic, or rubber. The magnetic core member is formed by performing an injection molding operation or a compressing molding operation of the composite member. Alternatively, the magnetic core member is a magnetic coating formed by applying and drying the composite member. A non-magnetic conductive plate that has a conductivity is layered on a surface of the air-core coil through which the magnetic core member is inserted. The conductive plate is made of a copper, a copper alloy, an aluminum or an aluminum alloy having 0.01 to 2 mm thickness. The antenna coil is operated by relatively high frequency while it is rigid relatively.
