[0020] A sixth aspect of an embodiment of the present invention is the RFID band according to the first to fifth aspects, wherein the RFID medium is configured by arranging an antenna and an IC chip on a base material having a strength stronger than that of the bag portion.

[0021] According to the sixth aspect of an embodiment of the present invention, since the RFID medium is configured by arranging an antenna and an IC chip on a base material having a strength stronger than that of the bag portion, it becomes easier to maintain a state in which the RFID medium accommodated in the bag portion is separated from the human body due to the strength of the base material.

[0022] A seventh aspect of an embodiment of the present invention is the RFID band according to the first to sixth aspects, wherein the RFID medium includes a first RFID unit corresponding to a first frequency band and a second RFID unit corresponding to a second frequency band different from the first RFID unit.

[0023] According to the seventh aspect of an embodiment of the present invention, since the RFID medium includes the first RFID unit and the second RFID unit, the applicable range of the RFID band can be expanded by applying RFID units having different communication distances to each.

[0024] An eighth aspect of an embodiment of the present invention is the RFID band according to the first to sixth aspects, wherein a second RFID medium is provided at a position different from the attachment position of the bag portion in the annular portion.

[0025] According to an eighth aspect of an embodiment of the present invention, by providing a second RFID medium at a position different from the attachment position of the bag portion in the annular portion, different RFID units can be applied to each.

[0026] A ninth aspect of an embodiment of the present invention is the RFID band according to the eighth aspect, wherein the second RFID medium corresponds to a frequency band different from that of the RFID medium housed in the bag portion.

[0029] According to a tenth aspect of an embodiment of the present invention, by providing the second RFID medium on the side opposite to the RFID medium, for example, when worn on the wrist, the first RFID medium can be arranged on the back of the hand and the second RFID medium can be arranged on the palm side.

[0030] An eleventh aspect of an embodiment of the present invention is the RFID band according to the eighth aspect, wherein one end portion of the bag portion is attached to the outer peripheral surface, the other end portion of the bag portion is a free end, and the second RFID medium is provided on the outer peripheral surface of the annular portion located between the bag portion and the annular portion.

[0031] According to an eleventh aspect of an embodiment of the present invention, by providing the second RFID medium on the outer peripheral surface of the annular portion located between the bag portion and the annular portion, it becomes easier to maintain a state in which the other end portion side of the bag portion is separated from the outer peripheral surface of the annular portion.

[0034] A thirteenth aspect of a certain aspect of the present invention is the RFID band according to the first aspect, which is attached to a human body's arm, leg, or the like.

[0035] According to the thirteenth aspect of a certain aspect of the present invention, since it is attached to a human body's arm, leg, or the like, it can be applied to the identification and verification of the human body to which the RFID band is attached.

[0036] A fourteenth aspect of a certain aspect of the present invention is an RFID band formed by attaching a bag portion containing an RFID medium to the outer peripheral surface of an annular portion at least partially stretchable.

[0037] According to the fourteenth aspect of a certain aspect of the present invention, since the bag portion containing the RFID medium is attached to the outer peripheral surface of the stretchable annular portion, it is possible to easily attach and detach the RFID band to and from the object to be attached.

[0038] A fifteenth aspect of a certain aspect of the present invention is the RFID band according to the fourteenth aspect, wherein the bag portion has an opening and a closing portion, the closing portion side is a free end, the RFID medium is inserted through the opening, and the opening side is sewn to the outer peripheral surface.

[0039] According to the fifteenth aspect of a certain aspect of the present invention, the RFID medium is inserted through the opening of the bag portion, the opening side is sewn to the outer peripheral surface, and the closing portion is a free end. Therefore, when the RFID band is attached to a part of the human body such as the wrist, the free end side of the bag portion is separated from the human body, making it less likely to be affected by communication interference from the human body.

[0040] [First Embodiment] Hereinafter, the RFID band 1 according to the first embodiment of the present invention will be described.

[0041] FIG. 1 is a perspective view for explaining the RFID band 1 according to the embodiment of the present invention. FIG. 2 is an explanatory view for explaining the bag portion 20 of the RFID band 1. FIG. 3 is a plan view for explaining the RFID inlay 30 accommodated in the bag portion 20 of the RFID band 1 according to the first embodiment.

[0042] The RFID band 1 in the present embodiment includes an annular portion 10 and a bag portion 20. The bag portion 20 is attached to the annular portion 10. That is, the RFID band 1 is configured by attaching the bag portion 20 in which the RFID inlay 30 is accommodated to the stretchable annular portion 10.

[0043] The bag portion 20 houses an RFID inlay 30 provided with an antenna and an IC device in a predetermined pattern as an example of an RFID medium corresponding to the RFID (Radio Frequency Identification) technology for transmitting and receiving information by non-contact communication.

[0044] <Annular Portion> The annular portion 10 is, for example, an annular and stretchable fabric formed using stretchable materials such as rubber, silicon, and polyurethane, stretchable processed yarns, and various synthetic fibers such as polyester fibers. The bag portion 20 is attached to the outer peripheral surface 11 of the annular portion 10 which is a rubber tape. At least a part of the annular portion 10 may be configured to be stretchable.

[0045] Since it is easy to widen the diameter of the annular portion 10, the annular portion 10 can be easily attached to and detached from, for example, the arm or leg of a human body (user) without separating the annular portion.

[0046] For example, when it is assumed that the annular portion 10 is worn on a child's wrist, the outer peripheral length can be set to about 140 mm in the normal state where the annular portion 10 is not extended.

[0047] Further, the annular portion 10 has water repellency. The annular portion 10 may be subjected to a water repellency treatment after being woven, or may be formed using water-repellent fibers. Since the annular portion 10 has water repellency, even if liquid is applied to the annular portion 10, it is difficult for the liquid to penetrate. Therefore, the annular portion 10 can be made difficult to get dirty.

[0048] <Bag portion> As shown in FIG. 2, the bag portion 20 has a rectangular shape having a long side portion 20L and a short side portion 20S, and can be formed by folding a single piece of cloth C in half. By sewing the long side portion 20L and the short side portion 20S after folding, it is possible to form a bag shape having an opening portion 21 and a closed portion 22. The broken line S2 shown in FIG. 2 indicates a seam.

[0049] As shown in FIG. 1, one end portion (one of the short side portions 20S), which is the opening portion 21 of the bag portion 20, is attached to the outer peripheral surface 11, and the other end portion (the other end of the short side portion 20S), which is the closed portion 22 of the bag portion 20, is a free end. In the present embodiment, the opening portion 21 of the bag portion 20 is sewn to the outer peripheral surface 11 of the annular portion 10. FIG. 1 shows a seam S1 that sews the bag portion 20 and the annular portion 10.

[0050] An RFID inlay 30 is inserted into the bag portion 20 from the opening portion 21 and is housed in the bag portion 20. The opening portion 21 of the bag portion 20 is closed by being sewn to the outer peripheral surface 11.

[0051] The bag portion 20 is preferably made of a fabric with low stretchability. Thereby, when the RFID inlay 30 is housed, the bag portion 20 is likely to maintain its shape, so the bag portion 20 is likely to be separated from the annular portion 10.

[0052] The bag portion 20 also has water repellency. Similar to the annular portion 10, a water repellency treatment may be performed after weaving, or it may be formed using water-repellent fibers. Since the bag portion 20 has water repellency, even if liquid is applied to the bag portion 20, it is difficult for the liquid to penetrate.

[0053] <RFID inlay> As shown in FIG. 3, the RFID inlay 30 includes a base material 31, a first RFID unit 32, and a second RFID unit 33.

[0054] In the present embodiment, it is preferable that the base material 31 is formed of a material having a strength stronger than that of the bag portion 20. Thereby, when housed in the bag portion 20, the bag portion 20 can easily rise in a direction away from the outer peripheral surface 11 of the annular portion 10. Examples of materials applicable as the base material 31 include a single-layer resin sheet made of a single resin such as polyvinyl chloride, polyethylene terephthalate, polypropylene, polyethylene, polyethylene naphthalate, or a multilayer resin sheet formed by laminating a plurality of these single-layer sheets.

[0055] Further, the base material 31 may be a woven fabric using various synthetic fibers. The material of the base material 31 and the form of whether it is a sheet or a woven fabric can be appropriately selected. In the present embodiment, the base material 31 is a woven fabric using synthetic fibers.

[0056] The first RFID unit 32 corresponds to a first frequency band, and the second RFID unit 33 corresponds to a second frequency band different from that of the first RFID unit 32.

[0057] The first RFID unit 32 includes a first antenna 321 and a first IC device 322.

[0058] The first antenna 321 is connected to the first IC device 322 and corresponds to wireless communication using the first frequency band. As shown in FIG. 3, the first antenna 321 includes meanders 323 and 324 that extend symmetrically.

[0059] In the first embodiment, as an example of wireless communication using the first frequency band, wireless communication by radio waves using the UHF band (frequency 860 to 960 MHz) can be applied.

[0060] In wireless communication by radio waves, by using a communication device corresponding to the wireless communication, it is possible to communicate with a device in a range of, for example, several meters to a dozen or so meters from the communication device in response to the output of radio waves. Therefore, according to the first embodiment, the RFID band 1 in the range of several meters to a dozen or so meters from the communication device can be detected.

[0061] The second RFID unit 33 includes a second antenna 331 and a second IC device 332.

[0062] The second antenna 331 is connected to the second IC device 332 and corresponds to wireless communication using a second frequency band different from the first frequency band. As shown in FIG. 3, the second antenna 331 is a loop antenna.

[0063] In the first embodiment, as an example, the wireless communication using the second frequency band can be applied to near-field wireless communication (Near Field Communication: NFC) by electromagnetic induction using, for example, the HF band (3 MHz to 30 MHz, particularly, a specific frequency band of 13.56 MHz).

[0064] In wireless communication by electromagnetic induction, by using a communication device corresponding to the wireless communication, it is possible to communicate with a device in a range of, for example, several centimeters to a dozen or so centimeters from the communication device in response to the output of radio waves. Therefore, according to the first embodiment, the RFID band 1 in the range of several centimeters to a dozen or so centimeters from the communication device can be detected.

[0065] As an example, the first antenna 321 and the second antenna 331 are formed by sewing an antenna wire made of metal fiber to a base material 31 which is a woven fabric.

[0066] Also, although not shown, the first IC device 322 and the second IC device 332 are each provided with an IC chip and a memory. Information about, for example, the wearer wearing the RFID band 1 or the object to which the RFID band 1 is attached can be stored in the memory via a reader.

[0067] <Function and Effect> FIG. 4 is an explanatory diagram for explaining a state in which the RFID band 1 is worn on the wrist. According to the RFID band 1, since the bag portion 20 in which the RFID inlay 30 is accommodated is attached to the expandable and contractible annular portion 10, it is possible to easily attach and detach the RFID band 1 to / from the object to be attached (wrist) without separating the annular portion 10.

[0068] In the RFID band 1, since one end portion side of the bag portion 20 is sewn to the outer peripheral surface 11 of the annular portion 10 and the other end portion is a free end, as shown in FIG. 4, the bag portion 20 in which the RFID inlay 30 is accommodated is separated from the wrist. Therefore, the RFID inlay 30 housed in the bag portion 20 is less likely to be affected by communication interference from the human body.

[0069] Further, in the RFID band 1, the bag portion 20 has an opening portion 21 and a closing portion 22, and the opening portion 21 is closed by sewing the opening portion 21 side to the outer peripheral surface 11. For this reason, it is easy to accommodate the RFID inlay 30 from the opening portion 21 into the inside of the bag portion 20. Even when it is necessary to replace the RFID inlay 30, the replacement work can be easily performed.

[0070] In the RFID band 1, since the RFID inlay 30 is provided with the first RFID unit 32 and the second RFID unit 33, it is possible to support two types of communication bands, and the application range of the RFID band 1 can be expanded.

[0071] As an example, a case where the RFID band 1 is used in children-related facilities such as kindergartens, nurseries, and schools will be described.

[0072] In the memory of the first IC device 322 and / or the second IC device 332 of the RFID band 1, personal information for identifying the child wearing the RFID band 1 and additional information such as the presence or absence of allergies required for the child are stored in advance.

[0073] If the RFID band 1 is worn on a child's wrist, administrators such as nursery teachers and school teachers can detect the RFID band 1 of children within a predetermined range by using a communication terminal. That is, in a room or outdoors, a roll call operation of children can be performed.

[0074] Thus, even with a limited number of administrators, the roll call operation of children who are moving around can be performed easily and accurately.

[0075] In addition, if the administrator uses a communication terminal as needed to read the information in the memory mounted on the first IC device 322 and / or the second IC device 332 of the RFID band 1, the administrator can confirm the incidental information such as the presence or absence of allergies together with the personal information of the child.

[0076] Thus, when the administrator changes on a daily basis or when multiple administrators manage children, the workload of the handover operation between administrators can be reduced. Furthermore, it is possible to prevent the induction of human errors such as forgetting to report or mishearing and misstating, and it is possible to prevent accidents that may occur due to human errors.

[0077] In addition, in the RFID band 1 according to the first embodiment, a second RFID unit 33 corresponding to NFC is provided. Therefore, if a communication terminal corresponding to NFC is installed at the entrance and exit of a facility or a room, the entry and exit management can be performed by touching the RFID band 1 to the communication device when children enter and exit.

[0078] Thus, the workload of the entry and exit confirmation operation of children in the facility can be reduced. In addition, since it is not necessary to allocate personnel to the entry and exit confirmation operation, limited administrators can be assigned to other tasks. Also, even in that case, the safety will not be reduced.

[0079] [Second Embodiment] FIG. 5 is a perspective view for explaining the RFID band 2 according to the second embodiment of the present invention. For the same functions as those of the RFID band 1 according to the first embodiment shown in FIG. 1, the same reference numerals are given and detailed descriptions thereof are omitted.

[0080] In the RFID band 2 according to the second embodiment, instead of a second RFID unit being mounted on the RFID inlay housed in the bag portion 20, as shown in FIG. 5, a second RFID medium 40 is provided at a position different from the mounting position of the bag portion 20 in the annular portion 10.

[0081] In the second embodiment, since the second RFID medium 40 has a button shape, it can be easily attached to an arbitrary position on the outer peripheral surface 11 of the annular portion 10 made of a fabric.

[0082] In the second embodiment, as shown in FIG. 5, the second RFID medium 40 is provided at a position opposite to the mounting position of the bag portion 20 on the outer peripheral surface 11 of the annular portion 10.

[0083] Similar to the second RFID unit 33, the second RFID medium 40 includes an RFID unit corresponding to short-range wireless communication (NFC) by electromagnetic induction using the HF band. Thereby, by bringing the button-shaped second RFID medium 40 close to an NFC-compatible reader, communication with the reader can be performed.

[0084] <Operational effects> According to the RFID band 2 according to the second embodiment, a second RFID medium 40 corresponding to a second communication frequency band is provided at a position opposite to the mounting position of the bag portion 20 in which the RFID inlay 30 having an RFID unit corresponding to the first communication frequency band is housed.

[0085] For example, when worn on the wrist such that the bag portion 20 is located on the back of the hand side and the second RFID medium 40 is located on the palm side, the operation of bringing the second RFID medium 40 closer to the electromagnetic induction reader becomes easier. Also, since the bag portion 20 is located on the back of the hand side and is spaced apart from the outer peripheral surface 11 in a direction away from the human body, it becomes easier to communicate by radio wave wireless communication.

[0086] [Modification Example] <First Modification Example> FIG. 6 is a schematic diagram for explaining the RFID band 3 as a first modification example.

[0087] On the outer peripheral surface 11 of the annular portion 10 located between the annular portion 10 and the bag portion 20 of the RFID band 3, the second RFID medium 40 is attached.

[0088] In the RFID band 3, since the surface of the bag portion 20 on the annular portion 10 side abuts against the second RFID medium 40, the bag portion 20 is likely to rise in a direction away from the outer peripheral surface 11 of the annular portion 10.

[0089] Thereby, it becomes easier to maintain the state in which the RFID inlay 30 housed in the bag portion 20 is separated from the human body. Therefore, the RFID inlay 30 housed in the bag portion 20 is less likely to be affected by communication interference from the human body.

[0090] <Second Modification Example> FIG. 7 is a schematic diagram for explaining the RFID band 4 as a second modification example.

[0091] In the RFID band 4, the second RFID medium 40 is attached near the attachment position of the bag portion 20 in the annular portion 10.

[0092] In the RFID band 4, since the second RFID medium 40 is attached near the bag portion 20, on the outer peripheral surface 11 of the annular portion 10, the portions protruding from the annular portion 10 can be aggregated. Therefore, the handling property when attaching and detaching the RFID band 4 to and from the wrist or the like can be improved.

[0093] <Third Modified Example> FIG. 8 is a schematic diagram for explaining the RFID band 5 as a third modified example.

[0094] In the RFID band 5, one end (opening 21) of the bag portion 20 is attached to the outer peripheral surface 11 of the annular portion 10, and the other end (closed portion 22) side of the bag portion 20 is folded back in an annular shape and attached near the attachment position of one end of the bag portion 20.

[0095] In the RFID band 5, since the bag portion 20 containing the RFID inlay 30 can be formed in an annular shape, when the length of the long side portion 20L of the bag portion 20 becomes too long with respect to the annular diameter of the annular portion 10, the bag portion 20 can be bent.

[0096] Therefore, the operation of the wearer when the RFID band 5 is worn on the wrist or the like is not hindered. Also, the discomfort of the wearer can be reduced.

[0097] The form of the bag portion 20 shown as the third modified example is applicable not only to the bag portion 20 and the RFID inlay 30 according to the first embodiment, but can also be combined with the RFID bands according to the second embodiment, the first modified example, and the second modified example.

[0098] [Other Embodiments] Although the present embodiment has been described above, the above embodiment merely shows one application example of the present invention, and is not intended to limit the technical scope of the present invention to the specific configuration of the above embodiment.

[0099] In the first embodiment, it is not essential for the RFID inlay 30 to include the first RFID unit 32 and the second RFID unit 33, and only one of the RFID units is sufficient. That is, either one of the electromagnetic induction method and the wireless communication method is sufficient as long as there is one of the RFID units.

[0100] In the first embodiment, it has been described that the first RFID unit 32 and the second RFID unit 33 provided in the RFID inlay 30 are each provided with an IC device, but a plurality of antennas corresponding to the communication band may be connected to one IC device.

[0101] Further, the plurality of antennas may be a main antenna corresponding to a specific communication band and an auxiliary antenna functioning as a booster antenna for the main antenna. In this case, the auxiliary antenna may be electrically connected to the IC device and the main antenna to exhibit an amplification function, or may exhibit an amplification function without being electrically connected to the main antenna.

[0102] The method of forming the bag portion 20 is not limited to the method shown in FIG. 2. For example, a long cloth piece may be folded near the central portion, and the opposing long side portions may be sewn together to form a bag shape.
