Description

    The present invention relates to an IC built-in tag that transmits and receives data in a non-contact manner.

Conventionally, an IC built-in tag as shown in FIG. 6 is known. This IC built-in tag 21 incorporates a resonance circuit such as a thin film coil 24 as an “antenna” and an IC chip 25 between an upper paper 22 and a back paper 23, and an external device such as an external reader / writer (not shown). The IC chip 25 can be read and rewritten by a non-contact (wireless) method, and visible information can be printed on the upper paper 22 (see, for example, Patent Document 1).
Then, as shown in FIG. 6, a thread 27 or a tag pin (not shown) is inserted into a suspending hole 26 penetrating through the upper paper 22 and the back paper 23, and used as a price tag for clothing or decoration. Has been.
However, the IC built-in tag 21 as described above has a problem that the length of the thin film coil 24 as an antenna cannot be reduced due to the relationship between the resonance frequency and the capacitance. That is, in order to enable reading and rewriting from a distant distance, it is necessary to increase the resonance frequency, and it is necessary to increase the resonance frequency so that reading / rewriting from a further distance is desired. Inevitably, the thin film coil (antenna) 24 needs to be long, so that there is a problem that the size (size) of the IC built-in tag 21 cannot be reduced and cost cannot be reduced.
Further, since the thread 27 and the tag pin (not shown) are used when attaching to clothing, the cost of the thread 27 and the tag pin cannot be reduced, and the thread 27 and the tag pin (not shown) are inserted into the hanging hole 26. There is a problem that it takes time and effort, and the overall cost cannot be reduced including work efficiency.
