Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to cultured pearls, and more particularly to the structure of cultured pearl core materials that incorporate electronic signs that store information on the value and owner of each cultured pearl.
[0002]
[Prior art]
Traditionally, the value of pearls has been difficult for amateurs to judge, and at stores, it has been traded with a certificate attached. Therefore, when dealing with only pearls separated from the appraisal, it is necessary to re-appraise if the correspondence relationship is impaired, and the efficiency may be reduced during processing.
[0003]
Therefore, pearls have been individually accommodated in cases and bags to be distinguished, and tags or IC tags have been attached.
[0004]
However, if the tags are applied to the surface of the raw pearl, the surface pearl layer may be damaged in some cases. Moreover, it is inconvenient if it is individually accommodated in cases and bags.
[0005]
On the other hand, conventionally, in the field of IC tags, various information belonging to the owner of the tag is stored, and the information is updated by an external device. A coin or the like having the same function is also known. Further, there is known a device in which an antenna is provided in a device such as the IC tag, information is read / written from the outside via a wireless signal, and power is also supplied.
[0006]
However, there has not yet been proposed a method for recording information on individual ornaments and their affiliation information by inserting them into pearls or other ornaments.
[0007]
[Problems to be solved by the invention]
Therefore, the present inventor has conducted various studies with the aim of solving the above problems. As a result, firstly, conventional pearls have a nacre layer on the core of the shell, and the interior is left solid and unused, and secondly, in recent IC circuit technology From the development, there is a possibility that the IC chip can be accommodated in the space inside the pearl, thirdly, the pearl layer itself is excellent in radio wave transmission, and fourthly, it is electrically conductive in a spherical shape along the base of the pearl layer. It is possible to form an omnidirectional antenna by incorporating a substance, and fifth, an IC chip and an antenna are formed inside, and a protective layer is provided on the IC chip. Sixth, the new fact that internal IC chips and antennas do not undergo physical changes during the formation of nacres in the sea has been discovered. Providing new cultured pearls that can record affiliation information It was Omoita' to wear.
