Description

  The present invention relates to a pearl nucleus incorporating an electronic label inside, a method for producing a pearl nucleus, a pearl using the pearl nucleus, a method for detecting a position of an electronic label incorporated in the pearl, and a pearl using the detection method. Perforation method, pearl perforation device, information communication method with a pearl built-in electronic sign, and information communication device with a pearl built-in electronic sign.

  Cultured pearls are manufactured by inserting artificial pearl nuclei into pearl oyster shells such as pearl oysters and generating nacre on the surface of the pearl nuclei.

  The value of the pearls produced in this way is determined by evaluation items such as color, shape, size, presence or absence of scratches, and gloss. The results of the appraisers appraising each pearl are shown in the appraisal report (discrimination document), etc., and pearl transactions based on the appraisal results of each pearl with each pearl associated with the appraisal Has been done. However, in order to attach a paper-based certificate to a pearl that has a grain size of several millimeters to a few tens of millimeters, it is necessary to trade with the pearl stored in a case or bag. Is quite complicated. Further, if a tag or the like is directly attached to the pearl, the surface of the pearl layer may be damaged.

  Therefore, it has been proposed to embed an IC tag (RFID: Radio Frequency IDentification) capable of writing and reading predetermined information by wireless communication with an external device inside the pearl nucleus (see Patent Document 1). ).

  On the other hand, when processing pearls as jewelry, for example, when processing into a ring or the like, a fixing pin for inserting a non-through hole and fixing the pearl to the pedestal is inserted, and when processing into a necklace, silk thread A through-hole for passing a cord-like body such as the like is provided. In consideration of this, in Patent Document 1, the IC tag is disposed at a position avoiding the central axis of the pearl nucleus, and the surface of the pearl nucleus is provided with irregularities and markings to detect the position of the central axis from the outside. It is disclosed that it is possible to do this. In addition, by placing two or more IC tags at positions inside the pearl nucleus that are not on the same straight line passing through the center of the pearl nucleus, even if a through / non-through hole is opened, it is always possible to select either IC. There has been proposed a method in which a tag is left without being damaged (see Patent Document 2). In addition, it has been proposed to attach an IC tag to the through hole after forming a through hole through which the cord-like body passes through the pearl nucleus (see Patent Document 3).

For this reason, when the IC tag is accommodated in the pearl nucleus, it is desirable that the surface of the iC circuit portion or the antenna coil is previously subjected to a known rust prevention treatment using benzotriazole or the like. It is also effective to cover the IC tag with a resin or the like that does not allow moisture to pass regardless of whether or not the rust prevention treatment is performed.

  In the following description, the case where “Coil-on-Chip (trade name)” which is an IC tag is used as an electronic label will be described. However, in all embodiments of the present invention, the electronic label is limited to an IC tag. I can't. Various types of ultra-small recording media that can exchange information with external devices by various means such as communication, record predetermined information, and read them later as needed can be used.

  Further, in all the embodiments of the present invention, even when an IC tag is used as an electronic label, it is not limited to the above-described “Coil-on-Chip (trade name)” or one having a similar configuration. There are no particular restrictions on the specific forms, such as those that have their own power source for driving and those that have the antenna element and the chip as separate members.

  Next, an embodiment of the pearl nucleus according to the present invention will be described.

  The first pearl nucleus according to the present invention is incorporated in a housing portion arranged at a position where the electronic label is unevenly distributed from the center, and the pearl nucleus passes through the center and is in two parts on a plane not including the electronic label. In the case of division, a weight adjusting unit is provided that changes the weight of the portion on the side including the electronic label and the portion on the side not including the electronic label.

  FIGS. 4 (a) and 4 (b) are diagrams showing the configuration of the first pearl nucleus according to the present invention, showing the part on the side where the IC tag as an electronic label is arranged. FIG.

  The pearl nucleus 20 according to the embodiment of the first pearl nucleus of the present invention shown in FIG. 4A is compared with the typical pearl nucleus 10 incorporating an electronic label shown in FIGS. Only the configuration of the accommodating portion 4 that accommodates the IC tag is different. For this reason, the same code | symbol is attached | subjected to the same member as the pearl nucleus 10 shown in FIGS. 1-3, and detailed description is abbreviate | omitted.

  The first pearl nucleus 20 of the present invention includes a pearl nucleus body 1, a housing part 4 having a circular horizontal cross section formed in the pearl nucleus body 1, and a lid body 2 that covers an opening part of the housing part 4. Yes. Here, the reason why the storage section has a circular horizontal cross section is that it can be easily machined with a drill, and the horizontal cross section of the storage section and the recess described later is not limited to a circular shape.

  As shown in FIG. 4 (a), in the first pearl nucleus 20, the accommodating part 4 is formed to a deep position on the center side of the pearl nucleus 20, and the IC tag 3 is not the bottom surface 4a of the accommodating part 4, It is fixed to the inner part of the lid 2 with an adhesive 5.

  In this way, in the pearl nucleus 20 of the first embodiment shown in FIG. 4A, the gap 6 is formed between the IC tag 3 and the bottom surface 4 a of the housing portion in the housing portion 4. ing.

  The IC tag 3 as an electronic label used for the pearl nucleus 20 of the present embodiment is mainly composed of a silicon substrate, and its specific gravity is about 2.33 and the specific gravity of the shell used for the pearl nucleus body 1. It is not very different from about 2.71. For this reason, when the IC tag 3 is inserted into the pearl nucleus 20 and the lid body 2 that almost closes the space portion of the accommodating portion 4 formed in the pearl nucleus body 1 is used like the lid body 2 shown in FIG. That is, when a part of the pearl nucleus is replaced with an IC tag, the IC tag is divided into two parts by a reference plane that passes through the center of the pearl nucleus 10 and does not include the IC tag 3. A difference in weight between the portion including the tag 3 and the portion not including the IC tag 3 hardly occurs.

  On the other hand, in the pearl nucleus 20 shown as this embodiment, the cavity 6 as a weight adjustment part is formed inside the pearl nucleus 20 by forming the accommodating part 4 deeply, and the hemisphere on the side where the IC tag 3 is arranged. The weight of 20a is made lighter than the weight of the hemisphere 20b on the side where the IC tag 3 is not arranged.

  In addition, the cavity may be coated with resin from the waterproof surface of the core material, and by filling the resin with a specific gravity close to 1, it is possible to ensure a specific gravity difference from shellfish. .

  As described in detail later, by providing a cavity as a weight adjusting unit that varies the weight of the side including the IC tag arranged inside the pearl nucleus and the side not including the IC tag, Even in the case of a pearl as a finished product in which a pearl layer is formed around the pearl nucleus, it is possible to detect the placement position of the IC tag using the difference in weight.

  In FIG. 4 (a), the IC tag 3 is bonded to the inner part of the lid 2 because the "Coil-on-Chip (trade name)" used as the IC tag 3 as described above. Since the communicable distance is 3 mm, information communication with the reader / writer across the pearl layer formed on the outer surface of the pearl nucleus cannot be performed if it is arranged at the bottom 4 a of the housing part 4 formed deeply. It is. Further, since the IC tag 3 is not fixed, the bottom surface 4a of the housing portion 4 is not processed into a flat surface, but remains in a shape along the shape of the cutting drill.

  FIG.4 (b) is a principal part expanded sectional view which shows the structure of the pearl nucleus 20 'concerning another embodiment of the 1st pearl nucleus of this invention.

  The pearl nucleus 20 ′ according to another embodiment shown in FIG. 4B is configured such that the pearl nucleus 20 ′ is parallel to the reference plane without cutting the accommodating portion 14 that accommodates the IC tag 3 from the surface of the pearl nucleus 20 ′. The cross section is cut at a cutting surface 13 that does not pass through the center O, and is divided into two parts, a part 11 that includes the center O and a part 12 that does not include the center O. Forms the accommodating portion 14 as a circular recess. In addition, in the pearl nucleus 20 'of another embodiment shown in FIG.4 (b), the same code | symbol is provided to the part of the same structure as the pearl nucleus 20 of Fig.4 (a).

  In the pearl nucleus 20 ′ according to another embodiment shown in FIG. 4B, the size of the IC tag 3 that accommodates the diameter of the accommodating portion 14 formed on the cut surface 13 of the portion 12 on the side including the center O is larger. By enlarging and also taking the depth of the accommodating part 14, the surrounding part of the IC tag 3 is made into the cavity 6 as a weight adjusting part. As with the pearl nucleus 20 of the embodiment shown in FIG. 4A, the bottom surface 14a of the accommodating portion 14 is located deep with respect to the outer surface of the pearl nucleus 20 ′. In consideration, the IC tag 3 is fixed to the cut surface 13 of the portion 11 not including the center O with the adhesive 5. Further, the bottom surface 14a of the accommodating portion 14 is not a flat surface.

  By doing in this way, also in the pearl nucleus 20 'concerning another embodiment shown in FIG.4 (b), the cavity 6 as a weight adjustment part is formed in the pearl nucleus 20, and IC tag 3 is arrange | positioned. The weight of the hemisphere 20a on the side where the IC tag 3 is not made is made lighter than the weight of the hemisphere 20b on the side where the IC tag 3 is not arranged. As a result, as in the case of the pearl nucleus 20 according to the embodiment shown in FIG. 4 (a), even when the pearl is a finished product in which a pearl layer is formed around the pearl nucleus 20 ', the difference in the weight is obtained. It is possible to detect the arrangement position of the IC tag 3 using.

  Each of the pearl nuclei 20 and 20 ′ shown in FIG. 4A and FIG. 4B is a weight adjusting portion that is continuous with the accommodating portion formed to accommodate the IC tag inside the pearl nucleus. By forming the cavity, the weight of the hemisphere on the side where the IC tag is arranged is made lighter than the weight of the hemisphere on the side where the IC tag is not arranged. By doing in this way, in both cases shown in FIGS. 4 (a) and 4 (b), the pearl nucleus hemisphere is formed using a process for forming an accommodating portion for accommodating an IC tag in the pearl nucleus. The weight can be changed.

  However, in the first pearl nucleus of the present invention, the means for changing the weight between the side including the IC tag and the side not including the IC tag is not limited to the one that continuously forms the cavity that is the weight adjusting unit. .

  5 (a) and 5 (b) illustrate and explain a modification of the first pearl nucleus according to the present invention. 5 (a) and 5 (b), the modified pearl nucleus 30, 30 'includes an IC tag by providing a cavity in the hemisphere on the side where the pearl nucleus IC tag is not included. The hemisphere on the side to be attached is heavier than the hemisphere on the side not including the IC tag.

  Fig.5 (a) shows the 1st modification of the 1st pearl nucleus concerning this invention.

  The pearl nucleus 30 of the first modified example includes a pearl nucleus body 21, an IC tag 3 in which a horizontal section formed in the pearl nucleus body 21 is fixed in a circular accommodating portion 4, and an opening portion of the accommodating portion 4. The cover body 2 is formed. The pearl nucleus 30 of the first modification shown in FIG. 5A is a typical hemisphere on the side where the IC tag 3 is arranged, which is a typical example incorporating an electronic label as shown in FIGS. It is the same shape as the pearl nucleus 10 of shape. Moreover, it can do by making it the same material and the same magnitude | size as the pearl nucleus 10 of the typical shape which incorporated the electronic label | marker shown using FIGS. 1-3, respectively.

  The pearl nucleus 30 of the first modification shown in FIG. 5A does not include the IC tag 3 when the pearl nucleus body 21 is divided into two parts 21a and 21b at a reference plane passing through the center. After being divided into two parts 22 and 23 at the cutting surface 24 located on the side hemisphere, a recess 25 having a circular horizontal cross section is formed from the cutting surface 13 in the part 23 on the side where the IC tag 3 is not disposed. The recess 25 is a cavity 6 that is a gravity adjusting portion.

  By doing in this way, contrary to the pearl nucleus 20 and 20 'of this embodiment shown as FIG. 4 (a) and FIG.4 (b), hemisphere 21b by the side which does not contain IC tag 3 is made into A predetermined volume of the cavity 6 can be formed. As a result, the weight of the hemisphere 21a on the side including the IC tag 3 when divided into the two hemispheres 21a and 21b on the reference plane passing through the center O of the pearl nucleus and not including the IC tag 3 is obtained. Can be made heavier than the hemisphere 21b on the side not including the IC tag, and the weight difference can be increased. For this reason, even after the nacreous layer is formed on the outer surface of the nacreous nucleus, in which direction the pearl nucleus has a different weight, in this case, the hemisphere that is heavier on the side containing the IC tag? Can be more easily discriminated, and as a result, the side including the IC tag can be easily identified.

  FIG. 5B is an enlarged cross-sectional view showing a main part of a configuration of a pearl nucleus 30 ′ according to a second modification of the first pearl nucleus of the present invention. The pearl nucleus 30 ′ according to the second modification shown in FIG. 5B is the same as the pearl nucleus 30 of the first modification shown in FIG. Different. For this reason, in FIG.5 (b), the same code | symbol is provided to the part of the same structure as the pearl nucleus 30 of Fig.5 (a), and the description is abbreviate | omitted.

  The pearl nucleus main body 21 ′ of the pearl nucleus 30 ′ of the second modified example shown in FIG. 5B is obtained by cutting the hemisphere 21a on the side including the IC tag at the cutting surface 26 and the member on the side including the center O. An accommodating portion 27 having a circular horizontal cross section is formed at a substantially central portion of the cut surface 26, and the IC tag 3 is disposed and fixed to the bottom surface of the accommodating portion 27. By doing in this way, the operation | work which covers the accommodating part 27 after accommodating the IC tag 3 in the pearl nucleus 21 'can be performed as adhesion | attachment of the cut surface 26 which cut | disconnected, and the pearl shown to Fig.5 (a) As in the case of the core 21, it is not necessary to separately prepare the lid body 2 that covers the opening of the cylindrical accommodating portion 4. Further, since the work is re-adhesion of the cut surface 26, it can be expected that the outer surface of the pearl nucleus 21 'in a state in which the IC tag 3 is accommodated has a cleaner spherical surface.

  In the case of the pearl nucleus 30 ′ of the second modified example formed in this way, as in the case of the pearl nucleus 30, a reference that passes through the center O of the pearl nucleus and does not include the IC tag 3. When the surface is divided into two hemispheres 21a ′ and 21b ′, the hemisphere 21a ′ on the side including the IC tag 3 is heavier than the hemisphere 21b ′ on the side not including the IC tag 3. Can do.

  As described above, there are various methods for forming the cavity as the weight adjusting portion inside the pearl nucleus body, such as a method of applying the accommodating portion, a method of providing a cut surface in the pearl nucleus and forming a predetermined recess in the cut surface. A method is conceivable. In order to increase the difference in weight between the hemisphere on the side including the IC tag and the hemisphere on the side not including the IC tag with respect to the plane passing through the center O of the pearl nucleus, It is important to provide a cavity only in the hemisphere. Further, as will be described in detail later, when a pearl is used as a jewelery, a penetrating or non-penetrating hole is often drilled. In the case of a pearl nucleus having a built-in IC tag such as the pearl nucleus according to the present invention, the reference surface or the side on which the IC tag is not disposed avoiding the position of the IC tag so that the IC tag is not damaged when drilling. A through hole or a non-through hole is drilled in the hemisphere. In this way, when the hole used as a jewelry is connected to the cavity as the gravity adjusting portion, there is a possibility that inconvenience such as water may enter the inside of the cavity. It is preferred to avoid the location of holes drilled in the nucleus.

  As described above, when the first pearl nucleus according to the present invention is divided by a plane passing through the center of the pearl nucleus and not including the IC tag, the hemisphere on the side including the IC tag and the IC tag are not included. Various configurations including modifications have been described for pearl nuclei having different weights from the side hemisphere.

  However, the 1st pearl nucleus of this invention is not restricted to the structure illustrated above. As will be described later, when a pearl layer is formed in the pearl nucleus to make a finished product pearl, the balance of the center of gravity of the pearl is confirmed by rolling the pearl, etc. Any configuration that can be estimated is acceptable.

  For example, in each of FIGS. 4A, 4B, 5A, and 5B, a difference in weight between the hemispheres of the pearl nucleus is generated by providing a cavity as a gravity adjusting portion. However, the cavity can be filled with resin. Moreover, the difference in weight between hemispheres can also be formed by inserting a member having a larger specific gravity as a weight adjusting portion with respect to the member constituting the pearl nucleus inside the pearl nucleus. Thus, as a member that can be used as a weight having a large specific gravity, for example, lead glass having a specific gravity of 3.4 to 4.3 can be used. Note that since the IC tag writes and reads predetermined information by an electromagnetic wave from the outside, it is basically not preferable to use a metal that absorbs or shields the electromagnetic wave as a weight.

  Also, as will be described later, considering the balance of the center of gravity by rolling the completed pearls and estimating the placement position of the IC tag, the hemisphere on the side where the IC tag is placed and the IC tag placement The difference in weight with the hemisphere on the non-finished side is preferably at least 1% or more, more preferably 5% or more. On the other hand, considering that the pearls are rolled in the mother pearl shell and a pearl layer is formed on the surface of the pearl, if the distribution of the center of gravity of the pearl nucleus is too extreme, the pearl layer with a uniform film thickness May be difficult to form, and the finished pearl may have a shape that cannot be called a substantially spherical shape. From this viewpoint, when the weight of the hemisphere on the side containing the IC tag and the hemisphere on the side not containing the IC tag is 70% or less, more preferably 40% or less. preferable.

  In addition, since the pearl nucleus does not float in seawater, it is made larger than 1.03 as the apparent specific gravity. The apparent specific gravity is preferably 1.5 to 2.7, and more preferably 2.0 to 2.6.

  Next, the 2nd pearl nucleus of this invention is demonstrated with reference to drawings.

  The second pearl nucleus according to the present invention is composed of two members formed by dividing a substantially spherical member by a dividing plane perpendicular to the central axis passing through the center, and is formed on one of the two members. The formed annular convex part and the annular concave part formed in the other member are fitted.

  6, 7, and 8 are views showing the configuration of the second pearl nucleus according to the present invention, and FIG. 6 (a) is a top view when the divided surface is placed horizontally. 6B is a side view, FIG. 6C is a bottom view, FIG. 7 is a sectional view from the side direction, and FIG. 8 is an exploded perspective view.

  As shown in FIG. 6A, FIG. 6B, and FIG. 6C, a pearl nucleus 40 that is an embodiment of the second pearl nucleus according to the present invention includes a pearl nucleus body 31 and a lid body 32. It consists of and. Since the pearl nucleus body 31 and the lid body 32 are joined by a split surface perpendicular to the central axis passing through the center of the pearl nucleus, the pearl nucleus 40 in which the pearl nucleus body 31 and the lid body 32 are joined is externally provided. When viewed, a joining line 33 formed in an annular shape is recognized on the outer surface of the pearl nucleus 30.

  As shown in the cross-sectional view of the pearl nucleus 40 shown in FIG. 7 and the exploded perspective view showing the state where the pearl nucleus body 31 and the lid body 32 shown in FIG. 8 are not joined, the pearl nucleus 40 of this embodiment is An annular convex portion 34 centering on the central axis Y of the pearl nucleus 40 is formed from the dividing surface 31 a of the main body 31, and an annular concave portion 35 centering on the central axis Y of the pearl nucleus 40 is formed on the dividing surface 32 a of the lid 32. Is formed.

  The height h of the annular projection 34 formed on the pearl nucleus main body 31 from the dividing surface 31a, the outer diameter L1 and the inner diameter L2 of the annular projection 34 are the same as those of the annular recess 35 formed on the lid 32. Corresponding to the depth d1 from the dividing surface 32a, the outer diameter L3 and the inner diameter L4 of the annular recess 35, the pearl nucleus body 31 and the lid body 32 are arranged so that the dividing surfaces 31a and 32a face each other. As a result, the annular convex portion 34 and the annular concave portion 35 are fitted.

  Inside the annular convex part 34 formed in the pearl nucleus body 31, a recess having a depth d2 is provided with respect to the joint surface 31a, and an electronic sign is formed by the inner wall of the annular convex part 34 and the bottom surface 36 of the concave part. An accommodating portion 37 for accommodating an IC tag is formed. The IC tag housed in the housing portion 37 is not shown in FIGS.

  When specific numerical examples of each member are given, when the diameter of the pearl nucleus is 10 mm and the above-mentioned “Coil-on-Chip (trade name)” is used as an IC tag built in the pearl nucleus, The distance x1 = 2.5 mm between the center of the pearl nucleus and the joint surface, the outer shape L1 of the annular convex portion and the outer shape L3 of the annular concave portion are 6.0 mm, the inner diameter L2 of the annular convex portion and the inner diameter L4 of the annular concave portion are 4. 5 mm, the height h of the annular convex portion can be 0.5 mm, and the depth d2 of the housing portion can be 1.2 mm. The outer shape L1 of the annular convex portion and the outer shape L3 of the annular concave portion, and the inner diameter L2 of the annular convex portion and the inner diameter L4 of the annular concave portion are designed with an appropriate margin of error.

  In addition, as a material of the pearl nucleus main body 31 and the cover body 32, a shell can be used similarly to the pearl nucleus mentioned above.

  As described above, the second pearl nucleus 40 of the present invention minimizes misalignment that may occur at the joint portion 33 on the outer surface of each other when the pearl nucleus body 31 and the lid body 32 are combined. Can be suppressed. For this reason, the outer surface of the pearl nucleus 40 in a state in which the IC tag is incorporated can be a more accurate spherical surface without unevenness, and the unevenness of the surface of the pearl nucleus can be achieved through the pearl layer formed on the outer surface. It can be avoided that the value of pearls has been recognized and the commercial value of pearls has declined.

  Moreover, in the pearl nucleus 40 demonstrated in this embodiment, the accommodating part 37 which accommodates an IC tag is used in the form which utilizes the inner wall of the annular convex part 34 inside the annular convex part 34 formed in the pearl nucleus main body 31. Formed. By doing in this way, since the accommodating part 37 which accommodates an IC tag can be formed simultaneously when forming the cyclic | annular convex part 34, a manufacturing process can be simplified and a low-cost pearl nucleus can be obtained. Can be realized.

  In addition, the pearl nucleus 40 which is an embodiment of the second pearl nucleus of the present invention shown in FIGS. 7 and 8 has an annular convex portion on the pearl nucleus body side on the joint surface between the pearl nucleus body and the lid. In the figure, an annular recess is formed on the lid side. However, conversely, an annular recess can be provided in the pearl nucleus body, and an annular protrusion can be provided in the lid. In this case, the pearl nucleus 40 shown in FIG. 7 and FIG. 8 is formed by forming an accommodating portion having a bottom surface at a position recessed from the joint surface inside the annular convex portion formed on the lid. Similarly, a pearl nucleus can be realized at a low cost, in which a joining line between the pearl nucleus main body and the lid body hardly appears.

  Further, as a further modification, it is conceivable to form an accommodating portion inside an annular recess formed on any joint surface of the lid and the pearl nucleus body. In this case, by making the outer diameter of the accommodating portion smaller than the inner diameter of the annular recess, it is possible to ensure that the annular protrusion and the annular recess are fitted on both the outer diameter and the inner diameter. The effect of effectively preventing the joining line appearing on the surface of the pearl nucleus after joining the lid can be maintained. However, since the inner wall of the annular recess cannot be used as the side wall of the housing portion, a process for forming the housing portion is required separately. On the other hand, when making the outer diameter of the accommodating portion the same as the inner diameter of the annular recess, that is, when forming a recess having a circular horizontal cross section on the joint surface, the step of forming the accommodating portion again is Although unnecessary, since there is no surface to be fitted to the inner wall of the annular convex portion, the effect of suppressing the positional deviation when joining the pearl nucleus body and the lid body is reduced.

<Method for producing pearl nucleus>
Next, the manufacturing method of the pearl nucleus concerning this invention is demonstrated.

  In the method for producing a pearl nucleus according to the present invention, an IC tag is accommodated in a member forming the pearl nucleus, and then the member is processed into a spherical shape to form a pearl nucleus.

  FIG. 9 is a diagram for explaining a process flow of the method for producing a pearl nucleus according to the present invention.

  First, as shown in FIG. 9A, a first member 51 and a second member 52 are prepared. The first member 51 has a first joint surface 51 a, and the first joint surface 51 a is joined to the second joint surface 52 a of the second member 52.

  In the example shown in FIG. 9, the first member 51 and the second member 52 have a rectangular parallelepiped shape in which both the first joining surface 51 a and the second joining surface 52 a are square. In addition, the thickness of the first member 51 is thinner than the thickness of the second member 52, and the sum of the thicknesses of the first member 51 and the second member 52 is equal to the first joint surface 51a and the second member 52. This is the same as the length of one side of the joint surface 52a. As specific dimensions, for example, the length of one side of the first joint surface 51a and the second joint surface 52a is 10 mm, the thickness of the first member 51 is 2 mm, The thickness can be 8 mm. In addition, as the 1st member 51 and the 2nd member 52, both can use a shell like a normal pearl nucleus.

  Next, as shown in FIG. 9B, an accommodating portion 53 for accommodating the IC tag is formed in the central portion of the second joint surface 52 a of the second member 52. In the present embodiment, since the above-mentioned “Coil-on-Chip (trade name)” with one side of 2.5 mm is used as the IC tag, the diameter of the accommodating portion 53 is 3.6 mm and the depth is 1 mm.

  Next, as shown in FIG. 9C, the IC tag 54 is bonded to the bottom surface of the housing portion 53 provided in the second member 52 with an epoxy adhesive or glue glue. Adhesives are stress and impact applied to the joined body during rolling, which will be described later, surface treatment with acid applied to the outer surface of the pearl nucleus after becoming a spherical body, phenolic resin in order to withstand the seawater environment during pearl layer formation, A thermosetting resin such as an epoxy resin is applicable. In order to improve the chamfering property and the polishing property of the bonded portion after curing, calcium carbonate powder can be added to the adhesive as a filler to approximate the shell base material.

  Thereafter, as shown in FIG. 9D, the second bonding surface 52a of the second member 52 and the first bonding surface 51a of the first member 51 are overlapped and bonded with an epoxy adhesive or the like. . Curing starts at the same time as adhesion, but it is desirable to cure at 15 ° C or higher.

  As described above, the sum of the thicknesses of the first member 51 and the second member 52 is the same as the size of one side of the first joint surface 51a and the second joint surface 52a. In the case of this example, the joined body 55 of the first member and the second member shown in FIG.

  Next, the bonded body 55 is chamfered by wear to be spherical. For example, according to the conventional pearl nucleus manufacturing process for manufacturing spherical pearl nuclei from shell pieces, multiple joints that are cubes of the same size are prepared and rolled so that the corners collide with each other. A spherical pearl nucleus can be produced.

  More specifically, a plurality of cubic joined bodies are put into a rotatable container, and chamfering is performed by rotating at a high speed for an appropriate time of, for example, about 10 minutes while adding a small amount of water. The chamfered joined body is sorted in a plurality of stages by a sorter. A plurality of the selected products are placed on a table having a round outer periphery, and a spherical shape is obtained by pressing a rotatable grindstone from above to rough finish.

  Further, after sorting in a plurality of stages by a sorter, polishing is performed with a finishing grindstone having a finer particle size than the above-described grindstone, and a final finishing process is performed. At this time, gold sand and abrasive are mixed. After the finished spherical joined body is polished, a sorting operation is performed, and a spherical pearl nucleus having a uniform size and no damage can be obtained by removing the scratched ball.

  FIG. 9 (f) shows a state in which a corner of the substantially cubic joined body 55 is taken and a spherical pearl nucleus 50 is manufactured. Of course, not only the joined body 55 manufactured by the manufacturing method described in FIG. 9 but also a pearl pearl nucleus that does not incorporate an IC tag inside, as a cubic shell member that rolls a plurality of pieces into a spherical shape. It can also be used by mixing the shell material used.

  In this way, as shown in FIG. 9 (g), a pearl nucleus 50 incorporating an IC tag can be manufactured.

  In addition, in the manufacturing method demonstrated using FIG. 9, the position of the joint surfaces 51a and 52a in the manufactured pearl nucleus 50 is made a pearl by making the thickness of the 1st member 51 and the 2nd member 52 different. The position is shifted from the center of the nucleus 50. By doing in this way, the arrangement position of the IC tag 54 arrange | positioned in the accommodating part 53 formed in the 2nd junction surface 52a can be easily made into the position unevenly distributed from the center of the pearl nucleus. However, it is not an essential requirement that the thicknesses of the first member and the second member used in the method for producing a pearl nucleus of the present invention are different. In addition, by appropriately determining the depth of the accommodating portion formed on the second joint surface, even when the first member and the second member have the same thickness, the IC tag placement position within the pearl nucleus can be determined. The position can be unevenly distributed from the center of the pearl nucleus.

  Here, the setting of the thickness of the first member 51 and the thickness of the second member 52 used in the IC tag manufacturing method of the present invention will be described with reference to FIG.

  When the antenna coil of the IC tag is arranged on the joint surfaces 51a and 52a of the first member 51 and the second member 52 as in the IC tag manufacturing method of the present invention shown in FIG. The thickness t1 of 51 requires that the thickness ta lost by polishing and the thickness tb of the pearl layer be smaller than the radio wave arrival distance tz of the IC tag 54. That is, (radio wave arrival distance tz)> (thickness t1 of first member 51) − (thickness ta lost by polishing) + (thickness tb of nacre).

  On the other hand, the thickness t2 of the second member 52 is related to the target pearl diameter D, (thickness t2 of the second member 52) = (pearl diameter D) − (thickness t1 of the first member 51). It can be set to satisfy the condition of + 2 × (thickness ta lost by polishing) −2 × (pearl layer thickness tb).

  The “thickness ta lost by polishing” can be changed by adjusting the polishing time. By applying this, pearl nuclei having different outer diameters can be manufactured using the first member 51 and the second member 52 having the same thickness.

  Furthermore, in the above embodiment, the joining surface of the first member second member is a square so that the joined body obtained by joining the first member and the second member forming the pearl nucleus becomes a substantially cubic body, In addition, the sum of the thicknesses of the first member and the second member (t1 + t2 in FIG. 10) is made equal to the length of one side of the joint surface. This is because, in the process of forming a joined body into a spherical body, the above-described method of making a plurality of joined bodies roll into a spherical shape by friction with each other in the same manner as in the conventional method for producing a pearl nucleus not incorporating an IC tag. This is because it is easy to use. However, in the method for producing a pearl nucleus of the present invention, it is not an essential requirement that the shape of the joined body be a cube.

  For example, regular tetrahedron, regular hexahedron, regular octahedron, regular dodecahedron, regular icosahedron, five types of regular polyhedron, truncated tetrahedron, truncated hexahedron, truncated octahedron, truncated dodecahedron, A semi-regular polyhedron such as a cubic octahedron or a truncated n-hedron can also be used. Further, by forming both the first member and the second member with a thinner peripheral portion with respect to the thickness of the central portion with respect to the joint surface, a shape close to a spherical state finally formed is formed. It can also be set as a joined body. Furthermore, when forming the joined body into a spherical state, an apparatus capable of shape processing by polishing or cutting is used without using the above-described method of rolling by mixing with another joined body or a pearl nucleation material. Needless to say, when molding into spherical bodies individually, restrictions on the shape of the joined body are further reduced.

  In the above-described method for producing a pearl nucleus according to the present invention, an IC tag is incorporated in a member that forms a pearl nucleus, and then, for example, a substantially cubic pearl nucleus member is worn by rolling to be spherical, It can be. By using this method, another method for producing a pearl nucleus is realized.

  The second method for producing a pearl nucleus according to the present invention is as shown in FIGS. 1 to 8, in which an accommodation portion is formed in a pearl nucleus once formed as a spherical body to accommodate an IC tag, and then this accommodation is performed. A substantially spherical pearl nucleus formed in the step of closing the part is used as a precursor. Such a precursor is made into a spherical body having a small diameter due to abrasion, as shown in FIG. 9 (e) by chamfering the substantially cubic joined body 55 into a spherical body 50 in FIG. 9 (f). It is.

  Specifically, a plurality of precursors are put into a rotatable container, and chamfering is performed by rotating at a high speed for an appropriate time of, for example, about 10 minutes while adding a small amount of water. The chamfered precursor is sorted in a plurality of stages by a sorter. A plurality of the selected products are placed on a table having a round outer periphery, and a spherical shape is obtained by pressing a rotatable grindstone from above to rough finish. Further, after sorting in a plurality of stages by a sorter, polishing is performed with a finishing grindstone having a finer particle size than the above-described grindstone, and a final finishing process is performed. At this time, gold sand and abrasive are mixed. After the finished spherical joined body is polished, a sorting operation is performed, and a spherical pearl nucleus having a uniform size and no damage can be obtained by removing the scratched ball.

  By doing in this way, even when irregularities occur on the outer surface of the pearl nucleus due to errors during the combination of members in the processing step of accommodating the electronic label inside the pearl nucleus and making it approximately spherical again, this It can be modified to make the outer surface of the pearl nucleus a clean spherical surface.

<Pearl>
Next, the pearl according to the present invention will be described.

  The pearl according to the present invention includes a pearl nucleus incorporating any of the IC tags according to the present invention described above, or a pearl nucleus incorporating an IC tag produced by the method for producing a pearl nucleus of the present invention, and a pearl nucleus And an pearl layer formed on the outer surface of the pearl nucleus.

  FIG. 11 is a diagram showing a cross-sectional configuration of a pearl according to the present invention.

  As shown in FIG. 11, a pearl 100 according to the present invention includes a pearl nucleus 40 incorporating the IC tag 3 according to the present invention described above, and a pearl layer 60 formed on the outer surface of the pearl nucleus 40. .

  The pearl 100 according to the present invention inserts (inserts) a pearl nucleus 40 containing an IC tag 3 into a pearl oyster such as an pearl oyster, and forms a pearl layer 60 on the outer surface of the pearl nuclei in the pearl oyster. It is a thing. The pearl layer 60 is said to have a pearl layer 60 of 0.3 μm formed by rotating the pearl nucleus inserted into the pearl mother shell once in about 6 hours and a half. For example, if it is one year, the pearl layer 60 of about 1330 layers and thickness of about 0.4 mm will be formed. The time during which the pearl nucleus is inserted into the pearl shell is determined so as to obtain the required thickness of the pearl layer 60. Thus, since the thickness of the pearl layer 60 formed on the outer surface of the pearl nucleus 40 is determined to some extent in advance, the thickness of the pearl layer 60 to be formed is taken into consideration. The depth from the outer surface of the pearl nucleus 40 of the IC tag 3 arranged in the inside 40 is determined.

  Although FIG. 11 shows an example in which the second pearl nucleus 40 according to the present invention is used as the pearl nucleus, the first pearl nucleus 20, 20 ′, 30, 30 ′ of the present invention is used as the pearl according to the present invention. Or the pearl nucleus 50 manufactured by the manufacturing method of the pearl nucleus concerning this invention can be used.

  In each of the above-described embodiments, the material using a shell is exemplified as the material for the pearl nucleus, but as the material for the pearl nucleus, in addition to the shell, calcium carbonate or other resin material is used. be able to. As the material for the pearl nucleus, it is preferable to use a shell having a large thickness. In addition, when it is difficult to obtain, calcium carbonate, limestone mainly composed of calcium carbonate, marble, calcite, araleite, etc. can be used.

<Method for detecting the position of the electronic sign built in the pearl>
Next, a method for detecting the position of the electronic sign built in the pearl according to the present invention will be described.

  The position detection method of the electronic sign built in the 1st pearl concerning this invention detects the gravity center position of the pearl in which the pearl layer was formed in the outer surface of a pearl nucleus, and the said pearl nucleus from the detected said gravity center position The position of the electronic sign built in the device is determined.

  The position detection method of the electronic label incorporated in the first pearl of the present invention is the position of the IC tag, which is the electronic label incorporated in the pearl nucleus not centered at the center of gravity described as the pearl nucleus according to the present invention. It is a method of detecting.

  For example, the center O in the pearl nucleus, such as the first pearl nucleus 20 of the present invention shown in FIG. 4A or the modified example 20 ′ of the pearl nucleus of the present invention shown in FIG. When the weight on the side where the IC tag is placed is small, the pearl layer is considered to be formed with a substantially uniform thickness. For example, the pearl can be rolled on a horizontally placed plane. By determining the position of the center of gravity (identifying the hemisphere of the light side and the hemisphere of the heavy side), the hemisphere on the side where the IC tag is arranged can be specified. Of course, as shown in FIGS. 5 (a) and 5 (b), the weight on the side where the IC tag is arranged with respect to the center O in the pearl nucleus is heavy, and the side where the IC tag is not arranged When the weight of the hemisphere is small, it can be estimated that the IC tag is built in the hemisphere portion on the heavy side determined by rolling the pearl.

  In addition to the method of rolling on the plane illustrated above as a method of determining the center of gravity of the pearl, for example, the pearl is formed by forming an air flow that blows upward after placing the pearl on the tip of the nozzle. Various methods can be used as long as the position of the pearl can be freely changed so that its center of gravity is on the lower side, such as a method of keeping the pearl freely rotating.

  In addition, as a rolling method in a flat shape, for example, by rotating the pearl at high speed so as to turn the frame, it can be expected that the one with a lighter center of gravity naturally rotates upward, and in this state the pearl nucleus The hemisphere on the heavier side can be identified.

  In the case of the pearl nucleus shown in FIGS. 9 and 11, the IC tag is arranged by taking a large accommodating portion for accommodating the IC tag and making the space inside the accommodating portion a cavity as a weight adjusting portion. This can be grasped as an example of reducing the weight on the side of the wing.

  In addition, the position detection method of the electronic sign built in the second pearl of the present invention is the method of detecting the position of the electronic sign built in the pearl nucleus while rotating the pearl having a pearl layer formed on the outer surface of the pearl nucleus. The built-in position of the electronic sign in the pearl nucleus is determined by performing wireless communication to determine the strength of the signal from the electronic sign.

  The pearl nucleus 20, 20 ′, 30, 30 ′ according to the present invention, the pearl nucleus 40 manufactured by the method for manufacturing the pearl nucleus of the present invention, or the pearl nucleus manufactured by the conventional manufacturing method shown in FIG. Like a pearl using 10, 10 ', etc., an IC tag, which is an embedded electronic label, is not placed at the center position of the pearl nucleus, and an IC tag placed inside the pearl is connected to an external device. By changing the direction of the pearl with respect to the external device while actually performing wireless communication between them, it is possible to determine the strength of the read signal. Naturally, since this signal is strong when the distance between the external device and the IC tag built in the pearl is small, it is possible to determine in which hemisphere inside the pearl the IC tag is built based on the strength of the signal. Can do.

  Specifically, the reader / writer antenna element capable of transmitting and receiving data to and from the IC tag is arranged horizontally, and the reader / writer is rolled while rolling the pearl on the plane formed on the upper surface of the antenna element. By detecting the reception intensity at, ie, the intensity of the signal received from the IC tag, the hemisphere on the side where the IC tag inside the pearl exists and the hemisphere on the opposite side can be specified. Of course, not only above the reader / writer, but also by arranging a space where the pearl can freely roll on the side surface side, the hemisphere on the side where the IC tag inside the pearl is placed and the hemisphere on the opposite side Can be determined.

  Furthermore, the position detection method of the electronic label incorporated in the third pearl of the present invention is used for the electronic label incorporated in the pearl nucleus while rotating the pearl having a pearl layer formed on the outer surface of the pearl nucleus. A radio wave having a resonance frequency of silicon is emitted to determine a built-in position of the electronic sign in the pearl nucleus.

  The position detection method of the electronic sign built in the third pearl according to the present invention does not communicate with the IC tag inside the pearl nucleus, unlike the position detection method of the electronic sign built in the second pearl. , By emitting a radio wave of the resonance frequency of the antenna element included in the IC tag, resonating the antenna element, and determining the strength of resonance of the antenna element, the hemisphere on the side where the IC tag is disposed and the IC tag A hemisphere on the side where it is not arranged is discriminated.

  As described above, the IC tag includes an antenna element such as a coil antenna in order to communicate with an external reader / writer. The resonance frequency of this antenna element is determined because of the necessity of good communication with the reader / writer. The third electronic sign position detection method of the present invention detects the arrangement position of the IC tag using the resonance frequency of the antenna element.

  Specifically, while radiating the signal of the resonance frequency of the antenna element, the pearl is rotated while monitoring the strength of the resonance with, for example, a dip meter, etc. Can be determined. As a method of rotating the position of the pearl with respect to a detector (measuring device) such as a dip meter, reading / writing is performed above or to the side of the detector in the same manner as the position detection method of the second built-in electronic sign. What is necessary is just to arrange | position the plane etc. which can rotate the target pearl.

  In the second built-in electronic sign position detection method and the third built-in electronic sign position detection method of the present invention, only the example of rotating the pearl has been described. It goes without saying that the position of the electronic sign built in the pearl can also be detected by rotating an external device for detecting the built-in position of the electronic sign.

  As described above, according to the position detection method of the built-in electronic label according to the present invention, the arrangement position of the IC tag that is deviated from the center inside the pearl can be detected from the outside. By using such a built-in position detection method for an electronic sign, there is an effect that a drilling step necessary for processing a pearl described later as a jewelry can be performed under better conditions.

<Pearl drilling method and drilling device>
Hereinafter, a perforation method and a perforation apparatus according to the present invention will be described.

  The pearl perforation method of the present invention uses any one of the above-described built-in electronic marker position detection methods of the present invention to determine the location of the electronic marker in the pearl nucleus, and the pearl's electronic marker is incorporated. It drills in the hemispherical part on the non-side.

  Further, the pearl drilling device of the present invention comprises a mounting table for mounting a pearl, and a drill for drilling a hole that penetrates or does not penetrate the pearl, and the position of the built-in electronic sign of the present invention described above Based on the arrangement position of the electronic label in the pearl detected by the detection method, the pearl can be placed on the mounting table in a desired direction.

  The pearl drilling method and drilling apparatus of the present invention will be described below with reference to the drawings.

  FIG. 12 is a diagram showing a schematic configuration of a pearl drilling apparatus according to the present invention.

  As shown in FIG. 12, a pearl drilling apparatus 200 according to the present invention includes a mounting table 120 on which a pearl 100 disposed on a base 110 is mounted, and a drill that is movable relative to the mounting table 120. 130. In the drill 130, the drill teeth 132 are rotated by a drill base 131 movable with respect to the pearl 100 base 110 and a motor 132 arranged on the drill base 131.

  In the perforating apparatus 200 shown in FIG. 12, since the reader / writer 121 capable of communicating with the IC tag 3 built in the pearl 100 is provided at the base of the mounting table 120, it is mounted on the mounting table 120. In this state, the output of the information recorded on the IC tag read by the reader / writer is confirmed while rotating the direction of the pearl 100 as shown by the arrow shown in FIG. The position of the IC tag 3 incorporated in the pearl nucleus 10 of the pearl 100 can be detected by the above-described method for detecting the position of the electronic label incorporated in the present invention. As shown in FIG. It adjusts so that it may become a position nearest to the writer 121, ie, it may come to the position of the pole below the pearl on the mounting base 120. In this state, if necessary, the pearl is firmly fixed by a pearl fixing device (not shown), and the drill is moved by the drill base 131 in the direction of the white arrow 150 in FIG. A through hole 140 is drilled in the surface (horizontal plane).

  Thus, based on the position detection method of the electronic sign built in the present invention, the position of the IC tag in the pearl is grasped, and the equator of the pearl is set in a state corresponding to the pole of the pearl. By drilling a through hole in the surface, the through hole formed in the case of a necklace can be reliably drilled at a position different from the IC tag placement position.

  In FIG. 12, as a method for detecting the position of the electronic sign built in the present invention, wireless communication with the electronic sign built in the pearl nucleus is performed to determine the strength of the signal from the electronic sign, thereby Although the method of judging the built-in position in the pearl nucleus was used, the dip meter illustrated above is arranged at the base of the mounting table 120, so that it is used for the electronic label built in the pearl nucleus while rotating the pearl. The position of the IC tag built in the pearl using a method of determining the built-in position in the pearl nucleus of the electronic sign from the change in the strength of the resonance that can be discriminated with a dip meter by emitting radio waves of the resonance frequency of the antenna element The through hole can be formed while avoiding the above.

  As mentioned above, although the example which determines the direction of a pearl on the mounting base which mounts a pearl was disclosed as a punching method and punching apparatus of this invention, before mounting on a mounting base as a punching method and punching apparatus of this invention, The position of the IC tag inside the pearl is detected, and the pearl is placed on the mounting table so that the IC tag is positioned at one of the poles of the pearl. Can be formed. In this case, it is possible to use a method of detecting the position of the IC tag in the pearl by detecting the position of the center of gravity of the pearl nucleus.

  Needless to say, the opening for piercing the pearl is not limited to the opening penetrating the pearl, and can be a non-penetrating opening reaching the approximate center of the pearl.

  Further, as shown in FIG. 13, the pearl 100 is placed on the mounting table 120 so that the position of the IC tag is in the horizontal direction when it is placed on the mounting table, and is on the side opposite to the drill 130. Then, with the pearl 100 fixed, the IC tag 3 of the pearl 100 is moved by moving the drill 130 in the direction of the white arrow 151 shown in FIG. 13 but moving the distance to the approximate center of the pearl without penetrating the pearl. The non-through-hole 141 formed from the opposite side to the side where is disposed can be formed.

  By doing in this way, when processing a pearl into a ring or a brooch, a non-through hole formed in the pearl can be reliably formed from the side opposite to the side where the IC tag is formed, An IC tag embedded in a pearl in a state of being processed into a jewelry such as a ring can be arranged near the surface, and information communication with the embedded IC tag can be easily performed.

  In addition, the said embodiment demonstrated the example which forms a through-hole or a non-through-hole from the horizontal surface direction in the pearl mounted on the mounting base with the drill. However, it is also possible to perform drilling by moving a drill drilled in the pearl from the vertical direction of the pearl mounted on the mounting table, particularly from above. In this case, when detecting the position of the IC tag inside the pearl on the mounting table, a reader / writer or a dip meter is placed on the side of the pearl to detect the state where the IC tag is positioned horizontally in the pearl. It can be so. Further, the position of the IC tag inside the pearl is detected at a place other than on the mounting table, and the IC tag is arranged in the horizontal direction of the pearl. Furthermore, when the opening formed in the pearl is a non-through hole, the position of the IC tag inside the pearl is detected on the mounting table or at a place other than on the mounting table, and the IC tag comes under the pearl. Can be.

<Information communication method and information communication device with pearl built-in electronic sign>
Next, an information communication method with the pearl built-in electronic sign according to the present invention and an information communication apparatus with the pearl built-in electronic sign will be described.

  According to the present invention, the information communication method with the pearl built-in electronic sign changes the direction of the pearl with respect to the reader / writer by rotating the pearl with the electronic sign built into the pearl nucleus, and the sensitivity of the electronic sign to the reader / writer is high. In the state, information is written to and / or read from the electronic sign.

  FIG. 13 is a diagram for explaining an information communication method with the pearl built-in electronic sign of the present invention. FIGS. 14 (a), 14 (b), 14 (c), and 14 (d) each show a state in which a pearl with a built-in electronic sign is rolling on a reader / writer.

  In the information communication method with the electronic label with a pearl of the present invention, the pearl 100 in which the IC tag 3 that is an electronic label is arranged inside the pearl nucleus 10 is written and read with respect to the IC tag 3. The wireless communication between the antenna element 210 of the reader / writer 300 and the IC tag is performed while rotating on the reader / writer 300 capable of reading, and writing to the IC tag is performed while maintaining a posture in which the reader / writer 300 has high reception sensitivity. Or read.

  As described above, in the pearl 100 described in this specification, “Coil-on-Chip (trade name)” is used as a small IC tag that can be incorporated in a pearl nucleus having a diameter of about 10 mm. An example is shown. When this "Coil-on-Chip (product name)" is used, the size of the IC tag including the antenna element is as small as 2.5 mm per side and 1 mm or less in thickness. Although it can be easily placed in the pearl nucleus, the communicable distance is as short as 3 mm or less.

  FIG. 14 shows the relationship between the IC tag 3 in the pearl 100 and the antenna element 201 of the reader / writer 300. In addition, in order to avoid that drawing becomes complicated, hatching which shows a cross section is not attached | subjected in FIG.

  FIG. 14A shows a case where the IC tag 3 is placed on the equatorial plane when compared to the horizontal position, the earth, in the pearl 100 placed on the reader / writer 300.

  As shown in FIG. 14A, in the state where the built-in IC tag 3 is located on the equator plane of the pearl 100, the communication range of the IC tag 3 indicated by the thick dotted line 220 in the figure (for example, centering on the IC tag). A spherical surface having a diameter of 3 mm does not reach the antenna element 210 that transmits and receives data in the reader / writer 300, and reliable communication cannot be performed in this state.

  This shows the state where the pearl 100 is rotated in the horizontal direction on the reader / writer 300, and also shows the other state where the IC tag 3 is located on the equator plane of the pearl 100. It is. In addition, as shown in FIG. 14C, when the IC tag 3 is located on the side different from the reader / writer 300 side in the pearl 100, that is, on the north pole side when compared to the earth above, The distance between the tag 3 and the antenna element 210 of the reader / writer 300 is maximized. In this case, communication between the IC tag 3 and the reader / writer 300 is impossible.

On the other hand, as shown in FIG. 14 (d), when the IC tag 3 is located on the lower side of the pearl 100, that is, on the south pole side, the communicable range 220 of the IC tag 3 is connected to the antenna element 210 of the reader / writer 300. Therefore, communication between the IC tag 3 and the reader / writer 300 becomes possible. In this way, the method for writing and reading the pearl-embedded electronic sign of the present invention is such that the pearl with the built-in electronic sign is rotated on the reader / writer to perform communication in a state where the signal is maximized. The communication between the IC tag and the reader / writer is performed by reading information stored in the IC tag while transmitting and storing a signal to be recorded in the IC tag. It is possible to write information in an optimal state.

  Further, when necessary information is already recorded in the IC tag and only reading by the reader / writer is necessary, the signal recorded in the IC tag is read by the reader / writer, so that FIG. ), The recorded data can be read reliably.

  In addition to this, for example, data for detection from the outside is recorded in advance on the IC tag, and when the distance between the IC tag and the reader / writer is detected while reading this data, the IC tag Necessary information to be stored can be recorded. In addition, as in the case of “Coil-on-Chip (trade name)” described in the present embodiment, when the IC tag operating power is also generated by an externally induced electromotive force, the signal from the reader / writer is used. By determining whether or not the IC tag is activated, it is possible to detect a state where the distance between the IC tag and the reader / writer is short, and to record information necessary for the IC tag in this state.

  FIG. 15: is a cross-sectional block diagram which shows the example of an information communication apparatus with the 1st pearl built-in electronic sign concerning this invention.

  As shown in FIG. 15, the information communication apparatus 400 with the pearl built-in electronic sign concerning this invention is equipped with the pearl stand 301 which mounts the pearl 100 rotatably freely.

  As shown in FIG. 15, the pearl bed 301 includes a bottom surface 302 that is a flat surface and is horizontally placed and a frame portion 303 formed around the bottom surface 302, and the pearl 100 freely rotates on the pearl bed. In addition, the pearl 10 is prevented from rolling off from the pearl base 301.

  A reader / writer 304 is arranged inside the bottom surface 302 of the pearl bed 301, and wireless communication can be performed with the IC tag 3 built in the pearl 100 rolling on the pearl bed.

  The reader / writer 304 is connected with a control device 305 such as a personal computer that can determine the reception state of the reader / writer 304 and can send and receive necessary information, and the pearl 100 rolls to the IC tag 3 and the reader / writer. The necessary information is written to the IC tag 3 and the information is read from the IC tag 3 while maintaining a posture in which the distance to the 304 is shortened and the communication sensitivity is increased.

  A pearl stop mechanism that suppresses the pearl 100 from above by a control signal from the control device 305 so that the rotation of the pearl 100 on the pearl bed 301 is stopped when the IC tag 3 and the reader / writer 304 approach each other. Can be provided.

  FIG. 16: is a figure which shows the information communication apparatus with the 2nd pearl built-in electronic sign concerning this invention.

  The information communication apparatus 500 with the 2nd pearl built-in electronic sign shown in FIG. 16 is an IC tag inside a pearl that is formed as a necklace by inserting a cord 410 such as silk thread into an internal through-hole 420 as a necklace. The information is written to and read from.

  As shown in FIG. 16, the information communication apparatus 500 with the 2nd pearl built-in electronic label | marker is provided with the detector 401 which can be contact-positioned on the side surface of the pearl 100 of a continuous pearl-shaped body. The detector 401 includes a reader / writer 402 connected to a control device 403 such as a personal computer on the inner side of the contact end portion of the tip. Information can be written to and read from the IC tag 3 incorporated in the pearl 100.

  As shown in FIG. 16, a pearl of a continuous pearl-like body cannot be freely rotated like a single pearl, but can be rotated around a measure-like body 410. As described with reference to FIG. 12, in the pearl selected by the pearl drilling method of the present invention, the through hole is formed in the equatorial plane with the IC tag in a position corresponding to the pole. When the measure-like body 410 is passed through 420 to be in a beaded state, the IC tag 3 is arranged at a position perpendicular to the through hole 420. For this reason, as the arrow shown in FIG. 16 rotates the pearl 100 around the through-hole 420, the distance between the reader / writer 402 inside the detector 401 and the IC tag 3 inside the pearl 100 changes. Thus, information can be written to and / or read from the IC tag 3 in a state where the distance is short and a sufficiently stable communication is possible.

  Note that the method for detecting the shortest distance between the IC tag and the reader / writer and the method for writing and reading information can be performed in the same manner as in the information communication apparatus with the first pearl built-in electronic sign described with reference to FIG.

  In addition, although not shown in FIG. 16, in the information communication device with the second pearl built-in electronic sign of the present invention, among the pearls in the form of pearls, the pearl that writes and reads information with a reader / writer. A pearl stand can be further provided. By doing in this way, while being able to specify clearly the pearl of a measuring object, it becomes easy to rotate only the pearl of a measuring object centering on a cord-like object. Moreover, when the pearl to be measured is continuous, information can be written and read sequentially.

  As described in detail with reference to FIG. 14, “Coil-on-Chip (trade name)” exemplified as an electronic sign in the embodiment of the present invention has a communication distance of 3 mm or less and is relatively small. For this reason, as shown in FIG. 16, even when the pearl is a continuous bead, only the “Coil-on-Chip (product name)” incorporated in a specific pearl can write and read information. And has the merit that there is no complication with the information recorded in “Coil-on-Chip (trade name)” incorporated in other pearls.

  As described above, the pearl nucleus in which the electronic label is incorporated in the pearl nucleus of the present invention, the method for producing the pearl nucleus, the pearl using the pearl nucleus, the method for detecting the position of the electronic label incorporated in the pearl, and the detection method therefor A pearl drilling method, a pearl drilling device, a method for writing and reading a pearl electronic label, and a device for writing and reading a pearl electronic label were described with reference to specific examples. In the above embodiment, the pearls and pearl nuclei are limited to spherical ones. However, the technical idea of the present invention is not applicable only to spherical pearl nuclei and pearls. The present invention can also be applied to a shape that can rotate in at least one direction, such as a body or a teardrop.

  In addition to the pearl identification results illustrated above, the information recorded on the electronic sign built in the pearl is related to the production location and year of the pearl, as well as the production of pearls such as the pearl nucleus and pearl mother shell. It is also possible to record information. By doing in this way, what is called traceability of each pearl can be provided. In addition to production information, distribution information such as distribution channels, distributors, and sales dates can also be recorded.

  A pearl nucleus incorporating an electronic label inside the pearl nucleus according to the present invention, a method for producing the pearl nucleus, a pearl using the pearl nucleus, a method for detecting the position of the electronic label incorporated in the pearl, and a method for detecting the same The pearl drilling method used, the pearl drilling device, the in-pearl electronic sign writing and reading method, and the in-pearl electronic sign writing and reading device can identify and manage the pearls with the built-in electronic signs, traceability Therefore, it can be used very effectively in quality assurance and trading in the pearl industry.
