Description

  The present invention provides an IC chip and an antenna in order to receive information from the outside using electromagnetic waves or radio waves as a medium, and to transmit information to the outside, such as an information recording medium for RFID (Radio Frequency IDentification) applications. The non-contact communication part built-in type metal housing | casing which incorporated the non-contact communication part comprised.

The IC tag is provided with an inlet composed of a base material, an antenna provided on one surface thereof and connected to each other, and an IC chip. When receiving an electromagnetic wave or a radio wave from an information writing / reading device, the IC tag Due to this, an electromotive force is generated in the antenna, the IC chip in the IC tag is activated by this electromotive force, and information in the IC chip is converted into a signal, and this signal is transmitted from the antenna of the IC tag.
Such an IC tag is attached to a casing constituting a box, container, container, etc. used for storing or storing an important article, for example. It is being used for the purpose of accurately managing articles by recording information about articles on an IC chip.

 In order for the IC tag to operate, electromagnetic waves or radio waves transmitted from the information reading / writing device must be sufficiently taken into the antenna of the IC tag, and an electromotive force greater than the operation electromotive force of the IC chip must be induced. However, when the IC tag is attached to the surface (outer surface) of the metal casing, in information communication using electromagnetic waves as a medium, the magnetic flux is parallel to the surface of the casing on the surface of the metal casing. There is a problem that the magnetic flux across the antenna of the IC tag is reduced, the induced electromotive force is lowered, the operating electromotive force of the IC chip is lowered, and the IC chip is not operated. In addition, when the IC tag is attached to the surface (outer surface) of a metal housing, in information communication using radio waves as a medium, the resonant frequency of the antenna shifts, so the induced electromotive force generated in the IC tag antenna decreases, There was a problem that the IC chip would not operate because it was below the operating electromotive force of the IC chip.

 Therefore, it has been studied to attach an IC tag to the surface of a metal housing through a magnetic material. In this case, it is very difficult to adjust the directivity of the antenna of the IC tag. Has a problem that it cannot receive radio waves from the information writing / reading device. For this reason, it may be necessary to change the orientation of the housing to which the IC tag is attached or the information writing / reading device so as to be able to communicate, improving work efficiency and storing in the housing. In some cases, it is difficult to accurately manage the goods. Therefore, for the purpose of managing goods, the IC tag attached to the surface of a metal housing should have a wide antenna directivity (weak directivity) to enable communication from all directions. Is desired.

 As an IC tag with a wide antenna directivity, for example, by using a plurality of individual tags composed of an antenna and a communication module, by arranging these individual tags in different directions on one surface of the substrate, A multi tag that can communicate in all directions is disclosed (for example, see Patent Document 1).

Japanese Patent Laying-Open No. 2005-094474

  However, since the multi tag disclosed in Patent Document 1 requires a plurality of individual tags and requires a space for providing the individual tags, the manufacturing cost is increased and the directivity of the multi tag is increased. In order to make it wide, there is a problem that it is difficult to adjust the arrangement of the antennas of each individual tag.

 Further, when the IC tag is attached to the surface (outer surface) of the housing, the IC chip may be damaged or destroyed by an external force, and information written on the IC chip may be damaged. Furthermore, there is a possibility that information relating to an article written in the IC chip and stored in the housing may be falsified or the IC tag may be forged.

Therefore, in order to prevent such a problem from occurring, it is necessary to dispose the IC tag in the housing so that the IC tag is not exposed to the outside.
However, when the IC tag is placed in a metal casing, radio waves do not enter the casing due to the effect of electrostatic shielding. Therefore, radio waves transmitted from the information reading / writing device are applied to the IC tag antenna. There is a problem that information cannot be communicated with the outside of the housing via radio waves.

  The present invention has been made in view of the above circumstances, and prevents a non-contact communication unit including an IC chip and an antenna from being damaged or destroyed by an external force.
