Description

  The present invention relates to a communication circuit holder, and more particularly, to a communication circuit holder provided with a semiconductor device having an RFID function.

  In recent years, a postcard system having confidentiality has been put into practical use and spread with the revision of the Postal Law. This friendly postcard system can be used, for example, to fold a postcard on which personal information or various information such as print information and print information is written, and to laminate a laminated body in which two transparent films are pseudo-bonded. It is a system that conceals these information and conceals these information, then mails them, and the recipient peels off the overlapped adhesive portion and reads the concealment information.

  In such a postcard system, the amount of information that can be recorded is limited by the size of the printing surface of the postcard or the size of characters, and a large amount of information cannot be recorded at a time. Thus, in order to record a large amount of information at a time, a postcard with an RFID tag has been devised in which a postcard system as described above is provided with an RFID (Radio Frequency Identification) tag. This postcard with an RFID tag can record a large amount of information on an IC chip constituting the RFID tag, and can add or change information (Patent Document 1, Patent Document 2, Patent Document) 3).

  However, in such a conventional postcard with an RFID tag, a large amount of information can be recorded on the IC chip, but means for preventing reading or rewriting of information by a third party has not been provided. For this reason, there is a possibility that information recorded on the IC chip may be read or rewritten by a third party inadvertently or intentionally before reaching the recipient's hand from the sender. Further, even if a conventional postcard with an RFID tag performs an illegal act such as reading or rewriting information by a third party, no means for confirming the fact has been provided. Thus, the conventional postcard with an RFID tag has a problem that the confidentiality of information cannot be maintained.

In addition, in the conventional postcard with an RFID tag, since the base material is a paper material, the strength is not sufficiently ensured, and when transporting from the sender to the recipient's hand or when using the RFID tag by the recipient The antenna, IC chip, circuit body, etc. may be damaged by vibration or external pressure. In addition, there has been a demand from users to provide diversity in the color and material of the base material for product differentiation.
JP-A-11-126238 JP 2001-126043 A JP 2003-141492 A

  The present invention has been made in view of the above circumstances, and can prevent reading and rewriting of information by a third party. Even if the reading and rewriting of information by a third party occurs, the fact is For communication with a semiconductor device that has an RFID function with excellent information confidentiality that can be easily known, even if vibration or external pressure is applied during transportation or use, antennas related to the RFID function are not easily damaged An object is to provide a circuit holder.

  In order to solve the above-mentioned problems, a communication circuit holder of the present invention includes a first base material provided with a circuit, a first conductor portion and a second conductor portion individually extending from the circuit, and a third substrate. A circuit holder for communication composed of a second base material provided with a conductor portion on one side, and provided so that one side of each other is in contact with each other, wherein the first base material and the second base material The overlapping surface is provided with a non-peelable strong adhesion region, and when the first base material and the second base material are overlapped, the first conductor portion and the second conductor portion are electrically connected. A portion of the third conductor portion that functions as a connecting means for connecting to the thin film is disposed in the non-peelable strong adhesion region, and further includes an inhibiting means for inhibiting the function of the connecting means.

According to this configuration, when the first base material and the second base material are overlapped, the antenna function is inhibited by electrically connecting the first conductor part and the second conductor part by the third conductor part. Therefore, reading and rewriting of concealment information by a third party can be prevented. In addition, in order to read and rewrite the concealment information, a third party releases the electrical connection between the third conductor portion, the first conductor portion, and the second conductor portion provided in the non-peelable strong adhesion region. Therefore, since it is necessary to destroy the strong adhesion region that cannot be peeled off, it is possible to grasp whether or not the concealment information is managed safely only by confirming the presence or absence of the destruction.
Moreover, since the 1st base material and 2nd base material which comprise the circuit holding body for communication are manufactured as a different body, a 1st base material and a 2nd base material can be easily manufactured with a different material. Therefore, the communication circuit holder can have sufficient strength. Further, even when the first base material and the second base material are manufactured using the same material, the thickness and color of the base material can be easily varied.

  In the communication circuit holder of the present invention, the non-peelable strong adhesion region and the peelable adhesion region are provided separately on the overlapping surface of the first base material and the second base material. It is preferable.

  In the communication circuit holding body of the present invention, it is preferable that the peelable adhesive region is a peelable and reattachable adhesive region.

According to the communication circuit holding body of the present invention, when the first base material and the second base material are overlapped, the first conductor portion and the second conductor portion are electrically connected by the third conductor portion. Since the antenna function is hindered, reading and rewriting of concealment information by a third party can be prevented. In addition, in order to read and rewrite the concealment information, a third party releases the electrical connection between the third conductor portion, the first conductor portion, and the second conductor portion provided in the non-peelable strong adhesion region. Therefore, since it is necessary to destroy the strong adhesion region that cannot be peeled off, it is possible to grasp whether or not the concealment information is managed safely only by confirming the presence or absence of the destruction.
Furthermore, since the third conductor portion is not electrically connected to the first conductor portion and the second conductor portion before the communication circuit holder is sent, the sender writes or rewrites data on the IC chip. It is possible to write and rewrite concealment information and print information.
In addition, since the first base material and the second base material constituting the communication circuit holder are manufactured separately, the first base material and the second base material can be easily manufactured from different materials. Therefore, the communication circuit holder can have sufficient strength. Further, even when the first base material and the second base material are manufactured using the same material, the thickness and color of the base material can be easily varied.

  Hereinafter, the communication circuit holder of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

In this case, the first print area 21 and the second print area 25 are peelable and re-pasteable adhesive areas, so that the first print area 21 and the second print area 25 are peeled along the perforation 23. It is possible to perform additional entry of concealment information.

  The recipient who has received the communication circuit holder 10 cuts off the cutting area 24 to make the RFID device 13 usable, and then peels off the second base material 12 from the first base material 11 to display the concealment information. read.
