Description

 The present invention enables reception of information from the outside and transmission of information to the outside in a non-contact state using radio waves or electromagnetic waves as an information recording medium for RFID (Radio Frequency IDentification) applications. The present invention relates to a non-contact type data receiving / transmitting body, and more particularly, to a non-contact type data receiving / transmitting body which can be directly attached to metal, receive information from the outside in a non-contact state, and transmit information to the outside Is.

An IC label, which is an example of a non-contact type data receiving / transmitting body, includes an inlet composed of a base material, an antenna provided on one side of the substrate, and an IC chip connected to each other. When a radio wave or electromagnetic wave is received from the device, an electromotive force is generated in the antenna due to a resonance action, and the IC chip in the IC label is activated by this electromotive force, and the information in the IC chip is converted into a signal. Transmitted from the antenna.
A signal transmitted from the IC label is received by the antenna of the information writing / reading device, sent to the data processing device via the controller, and data processing such as identification is performed.

 In order for these IC labels to operate, radio waves or electromagnetic waves transmitted from the information writing / reading device must be sufficiently taken into the antenna of the IC label, and an electromotive force higher than that of the IC chip must be induced. Don't be. However, when the IC label is attached to the surface of the metal article, the magnetic flux is parallel to the surface of the metal article on the surface of the metal article. For this reason, the magnetic flux across the antenna of the IC label is reduced and the induced electromotive force is lowered. Therefore, there is a problem that the induced electromotive force is lower than the operating electromotive force of the IC chip and the IC chip is not operated.

Therefore, a metal-compatible RFID tag is disclosed that includes a metal sheet portion and an RFID tag portion provided on the metal sheet portion, and the metal sheet portion includes a metal reflector and a spacer (for example, Patent Documents). 1).
By adopting such a configuration, the attachment position of the metal-compatible RFID tag can be separated from the metal article by a certain distance or more, so the influence of the metal-compatible RFID tag from the metal article can be reduced. The corresponding RFID tag can transmit and receive information.

International Publication No. 2006/114421 Pamphlet

When the above-described metal-compatible RFID tag is used by being attached to the surface of a metal article, a non-conductive adhesive material is provided on the back surface of the metal sheet portion. Then, the metal-compatible RFID tag is attached to the metal article through the adhesive material.
However, such a metal-compatible RFID tag is assumed because the distance between the antenna and the metal article, including the thickness of the adhesive material, is adjusted so that the resonance frequency of the antenna becomes a predetermined frequency. When an adhesive material having a thickness different from the thickness is used, there is a problem that the distance between the antenna and the metal article changes, the resonance frequency of the antenna shifts, and the communication characteristics change.

 The case where the thickness of the adhesive material is not the predetermined thickness is, for example, (1) When a different adhesive material is used for each user of the metal-compatible RFID tag, (2) Initially, the predetermined adhesive material is used. However, when other adhesive materials are used due to re-sticking, etc., (3) the adhesive material contains volatile components, and the volatile components volatilize over time, resulting in the thickness of the adhesive material For example, when the thickness becomes thinner.

In addition, when a metal-compatible RFID tag is attached to a metal article using an adhesive material, the adhesive material deteriorates over time, and its adhesive strength weakens, and the metal-compatible RFID tag falls off the metal article. There was a problem to do.
Therefore, a method of fixing the metal-compatible RFID tag to the metal article using a resin fastening band instead of the adhesive material is conceivable. However, the fastening band is sandwiched between the metal-compatible RFID tag and the metal article. Then, due to the thickness of the fastening band, the distance between the antenna and the metal article becomes larger than a predetermined size, and there is a problem that the resonance frequency of the antenna is shifted.

 The present invention has been made in view of the above circumstances, and is a non-contact type data receiving device in which the resonance frequency of the antenna does not shift even if it is fixed to the surface of a metal article by a band-like or string-like member such as a fastening band. An object is to provide a transmitter.

 The non-contact type data receiving / transmitting body of the present invention comprises a first base material and a second base material having an outer shape different from that of the first base material, and the first base material or the second base material. Any one of the non-contact data receiving and transmitting body comprising an IC chip and an antenna electrically connected to each other, penetrating the outer edge of the second substrate in the thickness direction, When the first base material and the second base material are overlapped, at least one through hole is provided at a position that does not overlap the first base material, and the thickness of the first base material is equal to the through hole. And having a thickness equal to or greater than the thickness of a band-like or string-like member for fixing the first base material and the second base material to an object.

 According to the non-contact type data transmitting / receiving body of the present invention, when the first base material and the second base material are superposed on the outer edge portion of the second base material in the thickness direction, At least one through hole is provided at a position that does not overlap the material, and the thickness of the first base material is inserted into the through hole, and a band or string for fixing the first base material and the second base material to the object Since the thickness of the shaped member is equal to or greater than, through the through hole of the second base material, from one surface side of the second base material to the other surface side of the second base material, When the non-contact type data receiving / transmitting body is fixed to the object by the member, since the member is not sandwiched between the object and the first base material, the non-contact type is not affected by the thickness of the member. The data receiving / transmitting body can be brought into close contact with the object. Therefore, due to the thickness (outer diameter) of the member, the distance between the antenna and the object does not become larger than the preset size (communication distance), and the resonance frequency of the antenna does not shift. Therefore, the non-contact type data receiving / transmitting body can be fixed to an object, particularly a metal article, without deteriorating communication characteristics.
