This command is, for example, a command requesting transmission of tag information. In this embodiment, the reader / writer 200 reads tag information at a predetermined cycle under the control of the control device 500. This cycle is, for example, one second.

[0026] Furthermore, when the antenna 270 of the reader / writer 200 receives radio waves containing tag information, the reader / writer 200 transmits the tag information indicated by the radio waves containing tag information to the control device 500. The radio waves containing tag information are radio waves containing tag information, and are radio waves emitted by the wireless tag 400 that has received the power supply radio waves and uses the power supply radio waves as a power source. In this embodiment, the reader / writer 200 reads tag information from the wireless tag 400 using a radio wave method that uses radio waves in the UHF (Ultra High Frequency) band, that is, frequencies between 300 MHz and 3 GHz (e.g., 920 MHz).

The storage unit 150 is fixed to the wearing unit 110 so as to be placed on the back of the left hand. The covering unit 160 is wrapped around the storage unit 150 so as to cover a portion of the surface of the storage unit 150.

[0037] The reader / writer 200 is stored inside the storage section 150 fixed to the attachment section 110, and is enclosed in the storage section 150 by the covering section 160. Therefore, the attachment section 110, the storage section 150, and the covering section 160 function to fix the reader / writer 200 to the back of the user's left hand. Note that FIG. 3 shows a state in which the opening of the storage section 150 is not covered by the covering section 160, and the reader / writer 200 can be inserted and removed from the storage section 150. The attachment section 110 also has a function to propagate radio waves used by the reader / writer 200. The covering section 160 also has a function to block radio waves not used for communication between the reader / writer 200 and the wireless tag 400.

[0038] Next, the configuration of the mounting unit 110 will be described in detail with reference to Fig. 4. Fig. 4(A) is a diagram showing the front surface of the mounting unit 110. Fig. 4(B) is a diagram showing the back surface of the mounting unit 110. The mounting unit 110 includes members 111, 112, 113, hook-and-loop fasteners 114, 115, 116, 117, 118, 119, a rubber band 120, a ribbon support unit 130, a member 141, and a member 142.

[0039] Members 111, 112, and 113 are sheet-like members that serve as a base on which each member is attached. A sheet-like member means a thin and flat shape. If a member is thin and flat, this member is sheet-like regardless of its shape when viewed in a plane. Members 111, 112, and 113 have shapes suitable for being fixed to the index finger of the left hand, the back of the left hand, and the palm of the left hand. Members 111, 112, and 113 have similar shapes and sizes when viewed in a plane, and are stacked in order and fixed.

[0040] In this embodiment, the method for fixing each component can be adjusted as appropriate. For example, the components can be fixed by sewing with thread, bonding with adhesive, or bonding with double-sided tape. Although not shown in Figure 4, the edges of these components can be covered with various fabrics.

[0041] The front surface of the attachment unit 110 is the surface where the front surface of the member 111 is exposed, and the back surface of the attachment unit 110 is the surface where the front surface of the member 113 is exposed. When the attachment unit 110 is worn on the left hand, the front surface of the attachment unit 110 is basically the surface exposed to the outside, and the back surface of the attachment unit 110 is the surface that comes into contact with the skin. The member 112 is preferably made of a cushioning material. The member 113 is the member that comes into contact with the human body, so it is preferably made of a cushioning, non-slip material.

[0042] The member 111 is made of, for example, a polyester fabric using Solotex (registered trademark). Solotex (registered trademark) is a polyester-based elastic fiber that is a composite fiber in which a polytrimethylene terephthalate component and a polyethylene terephthalate component are bonded side-by-side. The member 112 is made of, for example, a urethane foam, a urethane foam with a tricot, or the like. The member 113 is made of, for example, a double-russell knitted fabric using Nanofront (registered trademark). Nanofront (registered trademark) is an ultra-fine polyester fiber. The member 112 preferably has a thickness of about 2 mm. The member 113 preferably has a thickness of about 2 mm.

[0043] The hook-and-loop fasteners 114, 115, 117, and 118 are hook-and-loop fasteners for fastening the attachment part 110 to the index finger. The hook-and-loop fasteners 116 and 119 are hook-and-loop fasteners for fastening the attachment part 110 to the back and palm of the hand. The hook-and-loop fasteners 114 and 117 are detachable, the hook-and-loop fasteners 115 and 118 are detachable, and the hook-and-loop fasteners 116 and 119 are detachable.

[0044] For example, if hook and loop fasteners 114, 115, and 116 are hook-side hook and loop fasteners, hook and loop fasteners 117, 118, and 119 are loop-side hook and loop fasteners. Hook and loop fasteners 114, 115, and 116 are attached to the surface of member 111. Hook and loop fasteners 117, 118, and 119 are attached to the surface of member 113. Rubber band 120 is a rubber band that uses hook and loop fasteners 116 and 119 to attach attachment part 110 to the left hand with an appropriate force.

[0045] The ribbon support unit 130 is a member that supports the conductive ribbons 132. The configuration of the ribbon support unit 130 will be described in detail below with reference to Fig. 5. Fig. 5(A) is a diagram showing the front surface of the ribbon support unit 130. Fig. 5(B) is a diagram showing the back surface of the ribbon support unit 130. The ribbon support unit 130 includes a member 131, a conductive ribbon 132, a member 137, and a shield 138.

[0046] Member 131 is a sheet-like member that serves as a base to which conductive ribbon 132 is attached. Member 131 has a shape that is suitable for wrapping around the back of the left hand and the palm side of the left index finger. The front surface of member 131 is the surface that is exposed to the outside, and the back surface of member 131 is the surface that comes into contact with member 111. Member 131 is made of, for example, suede.

[0047] The conductive ribbon 132 is a member for propagating radio waves used for reading tag information by the reader / writer 200. The conductive ribbon 132 is a flat, elongated member that has been given conductivity. The conductive ribbon 132 is arranged on the surface of the member 131. The conductive ribbon 132 propagates radio waves used for reading tag information between the reading unit 135 and the arrangement unit 136. The reading unit 135 is a portion of the conductive ribbon 132 that is brought close to the wireless tag 400 to read the tag information. The arrangement unit 136 is a portion of the conductive ribbon 132 where the reader / writer 200 is arranged. The conductive ribbon 132 includes a conductive thread 133 and a member 134.

[0048] The conductive thread 133 is a thread-like member having electrical conductivity. The conductive thread 133 may be a thread produced by copper plating twisted fibers, a thread produced by twisting fibers wrapped in copper foil, or a thread produced by twisting carbon fibers. The member 134 is a member to which the conductive thread 133 is attached. The member 134 is a strip-like member having elasticity. The member 134 is made of, for example, rubber.

[0049] In the conductive ribbon 132, the conductive thread 133 is arranged in a meandering shape. That is, the conductive thread 133 is arranged on the member 134 in a meandering shape from the reading section 135 to the arrangement section 136. By arranging the conductive thread 133 in a meandering shape, the electromagnetic coupling between the conductive thread 133 and the antenna 270 is strengthened, and leakage of radio waves is reduced.

[0050] The method of attaching the conductive thread 133 to the member 134 can be adjusted as appropriate. For example, the conductive thread 133 may be attached to the member 134 by sewing the conductive thread 133 itself. Alternatively, the conductive thread 133 may be fixed to the member 134 by sewing another thread. Alternatively, the conductive thread 133 may be fixed to the member 134 with an adhesive. The reading unit 135 is an example of a reading unit. The placement unit 136 is an example of a placement unit.

[0051] Member 137 is a sheet-like member for ensuring a distance between conductive ribbon 132 and the user's hand. Member 137 is disposed on the rear surface of member 131 in a position facing the portion of conductive ribbon 132 other than placement portion 136. Member 137 is made of, for example, highly expanded polyethylene foam. From the viewpoint of reducing attenuation of electromagnetic energy, which will be described later, member 137 preferably has a thickness of about 3 mm.

[0052] The shield 138 is a sheet-like member that blocks radio waves. The shield 138 is positioned so that the conductive ribbon 132 is sandwiched between the shield 138 and the antenna 270. Specifically, the shield 138 is positioned opposite the placement portion 136 on the back surface of the member 131. The shield 138 functions to adjust the strength of the electromagnetic coupling between the antenna 270 and the conductive ribbon 132. The shield 138 is formed, for example, from an aluminum-vapor-deposited PVC (Polyvinyl Chloride) sheet. The aluminum-vapor-deposited PVC sheet is a film material formed by bonding an aluminum-vapor-deposited film to a polyester base fabric, and then coating the aluminum-vapor-deposited film and polyester base fabric with soft polyvinyl chloride. The aluminum-vapor-deposited PVC sheet has radio wave shielding properties due to the metal layer. Furthermore, the aluminum-vapor-deposited PVC sheet has high strength and can be sewn. Furthermore, the aluminum-vapor-deposited PVC sheet is flexible and therefore easily follows the movement of the fabric that makes up the wearing device. The shield 138 is attached to the member 131 by, for example, sewing. The shield 138 is an example of a second shield.

[0053] The ribbon support part 130 is sewn to the member 111 in a state in which the back surface of the member 131 is arranged to overlap the member 111. Here, it is preferable to sew the ribbon support part 130 and the member 111 together along the dashed line shown in FIG. 4A so that the covering part 160 can be passed between the member 111 and the member 131.

[0054] Members 141 and 142 are sheet-like members that are placed in positions that overlap with reading unit 135 in ribbon support unit 130. Members 141 and 142 have the same shape in a plan view. Member 142 is slightly larger than member 141 in a plan view. Members 142 and 131 are sewn together with member 141 sandwiched between them. Member 141 is made of, for example, polyolefin foam. Member 142 is made of, for example, artificial leather.

[0055] Next, the storage section 150 will be described with reference to Fig. 6. Fig. 6(A) is a diagram showing the storage section 150 before sewing, i.e., before it is formed by sewing. Fig. 6(B) is a diagram showing the storage section 150 after sewing, i.e., after it has been formed by sewing. The storage section 150 includes a member 151 and a member 154.

[0056] Member 151 is a sheet-like member that forms the outer shape of storage section 150. Member 151 has opening 152 and opening 153. Opening 152 is an opening that is not covered by member 154. Opening 152 is an opening that is provided, for example, so that a user can operate operation receiving unit 240 included in reader / writer 200 stored in storage section 150. Opening 152 may be used, for example, to connect a USB cable to a Universal Serial Bus (USB) terminal (not shown) for charging included in reader / writer 200.

[0057] Aperture 153 is an aperture that is covered by member 154. Aperture 153 is an aperture that is provided, for example, so that a user can visually check display unit 230 provided on reader / writer 200 stored in storage unit 150. Member 151 is preferably made of a material that is strong enough to maintain the shapes of apertures 152, 153, etc. (not shown) for inserting and removing reader / writer 200 in storage unit 150. Member 151 is made of, for example, artificial leather.

[0058] Member 154 is a transparent sheet-like member that is overlaid on member 151. Member 154 is provided to suppress distortion of opening 153. Member 154 is overlaid on member 151 so as to cover opening 153 but not opening 152, and is sewn to member 151. Member 154 is made of, for example, a PVC sheet, which is a transparent, soft polyvinyl chloride sheet.

[0059] The left, lower, and right ends of the storage section 150 before sewing shown in FIG. 6(A) are folded so that the surface with the member 154 faces outward, and then the bottom end of the left end and the left end of the bottom end are sewn together, and the bottom end of the right end and the right end of the bottom end are sewn together. The storage section 150 is then turned over so that the surface with the member 151 faces outward, completing the storage section 150 after sewing shown in FIG. 6(B). The completed storage section 150 is attached to the attachment section 110. Specifically, for example, the storage section 150 and the ribbon support section 130 are sewn together in a state where the storage section 150 is overlapped at a position corresponding to the placement section 136 of the ribbon support section 130 so that the member 154 faces the ribbon support section 130.

[0060] Next, the covering portion 160 will be described with reference to Figures 7 and 8. Figure 7(A) is a diagram showing the appearance of the front surface of the covering portion 160. Figure 7(B) is a diagram showing the appearance of the back surface of the covering portion 160. Figure 8 is an exploded perspective view of the covering portion 160. The covering portion 160 includes a member 161, a shield 162, a member 163, a member 164, a hook-and-loop fastener 165, a hook-and-loop fastener 166, a member 167, and a member 168.

[0061] Members 161 and 164 are sheet-like members that serve as bases on which the other members are attached. Shielding body 162 is a member that blocks radio waves unnecessary for the reader / writer 200 to read tag information. Member 163 is a sheet-like member that ensures a distance between the conductive ribbon 132 and shielding body 162. Members 161, 162, 163, and 164 have the same shape and size in a plan view. Members 161, 162, 163, and 164 are stacked and fixed in order. Although not shown in FIGS. 7 and 8, the edges of these members are covered with various fabrics.

[0062] The surface of the covering 160 is the surface on which the surface of the member 161 is exposed, and the back surface of the covering 160 is the surface on which the surface of the member 164 is exposed. When the covering 160 is wrapped around the storage unit 150, the surface of the covering 160 is basically the outer surface, and the back surface of the covering 160 is the inner surface. The member 161 is made of, for example, a polyester fabric using Solotex (registered trademark). The shielding body 162 is made of, for example, aluminum-deposited PVC. The member 163 is made of, for example, urethane foam, urethane foam with tricot, etc. The member 164 is made of, for example, a polyester fabric using Solotex (registered trademark). In consideration of the distance between the shielding body 162 and the conductive ribbon 132, which will be described later, it is preferable that the member 163 have a thickness of approximately 2 mm. The shielding body 162 is an example of a first shielding body.

[0063] The hook-and-loop fasteners 165 and 166 are hook-and-loop fasteners for wrapping and fixing the covering portion 160 around the storage portion 150. The hook-and-loop fasteners 165 and 166 are detachable, and when the hook-and-loop fastener 165 is a hook-and-loop fastener, the hook-and-loop fastener 166 is a loop-and-loop fastener. The hook-and-loop fastener 165 is attached to the surface of the member 161. The hook-and-loop fastener 166 is attached to the surface of the member 164.

[0064] Member 167 is a sheet-like member for ensuring the distance between conductive ribbon 132 and shield 162. Member 168 is a sheet-like member for attaching member 167 to member 164. In a plan view, member 167 is larger than member 168. With member 167 sandwiched between members 164 and 168, the edges of member 168 are sewn to member 164, thereby fixing member 167 to the surface of member 164. Member 167 is made of, for example, expanded polyethylene foam. Member 168 is made of, for example, a double-raschel knit fabric using Nanofront (registered trademark). In consideration of the distance between shield 162 and conductive ribbon 132, which will be described later, member 167 preferably has a thickness of approximately 5 mm.

[0065] The covering portion 160 is attached to the storage portion 150 attached to the mounting portion 110. Specifically, the covering portion 160 is inserted between the ribbon support portion 130 and the member 111 in the mounting portion 110, and is fixed to the mounting portion 110 in a state in which the member 167 in the covering portion 160 overlaps the arrangement portion 136 in the mounting portion 110.

[0066] Next, a method for reading tag information from a wireless tag 400 using the reading system 1000 will be described with reference to Fig. 9 . In Fig. 9 , the Z axis is an axis extending vertically, the X axis is an axis perpendicular to the Z axis, and the Y axis is an axis perpendicular to the X and Z axes. The direction in which the arrow of the X axis extends is the positive direction of the X axis, and the opposite direction to the direction in which the arrow of the X axis extends is the negative direction of the X axis. The direction in which the arrow of the Y axis extends is the positive direction of the Y axis, and the opposite direction to the direction in which the arrow of the Y axis extends is the negative direction of the Y axis. The direction in which the arrow of the Z axis extends is the positive direction of the Z axis, and the opposite direction to the direction in which the arrow of the Z axis extends is the negative direction of the Z axis. Hereinafter, the positive direction of the Z axis will be referred to as the upward direction, and the negative direction of the Z axis will be referred to as the downward direction, as appropriate.

[0067] First, the user attaches the reader / writer 200 to the wearable item 100. Specifically, the user places the reader / writer 200 in the storage section 150 and covers the storage section 150 with the covering section 160 by attaching the hook-and-loop fastener 166 to the hook-and-loop fastener 165. Then, the user wears the wearable item 100 on the left hand. Specifically, the user secures the wearable item 100 to the back and palm of the left hand by attaching the hook-and-loop fastener 119 to the hook-and-loop fastener 116 with the back and palm of the left hand wrapped around the member 113. Furthermore, the user secures the wearable item 100 to the index finger of the left hand by attaching the hook-and-loop fastener 117 to the hook-and-loop fastener 114 and the hook-and-loop fastener 118 to the hook-and-loop fastener 115 with the index finger of the left hand wrapped around the member 113.

[0068] The user then turns on the power to the reader / writer 200. After that, the reader / writer 200 starts reading tag information and periodically emits radio waves for power supply. When the user then brings the index finger of his / her left hand close to the wireless tag 400, the reader / writer 200 reads the tag information from the wireless tag 400.

[0069] Specifically, the reader / writer 200 emits radio waves for power supply from the antenna 270. Then, electromagnetic energy corresponding to the radio waves for power supply emitted from the antenna 270 is supplied to the arrangement portion 136 on the conductive ribbon 132 by electric field coupling, magnetic field coupling, radio wave transmission and reception, or a combination thereof. The electromagnetic energy supplied to the arrangement portion 136 on the conductive ribbon 132 propagates to the reading portion 135 on the conductive ribbon 132.

[0070] The electromagnetic energy propagated to the reading unit 135 in the conductive ribbon 132 is supplied to the antenna 440 provided in the wireless tag 400 by electric field coupling, magnetic field coupling, radio wave transmission and reception, or a combination thereof. The wireless tag 400 is activated by the electromagnetic energy received from the conductive ribbon 132, and emits radio waves containing tag information from the antenna 440. The electromagnetic energy corresponding to the power supply radio waves emitted from the antenna 440 is supplied to the reading unit 135 in the conductive ribbon 132 by electric field coupling, magnetic field coupling, radio wave transmission and reception, or a combination thereof.

[0071] The electromagnetic energy supplied to the reading section 135 in the conductive ribbon 132 propagates to the arrangement section 136 in the conductive ribbon 132. The electromagnetic energy propagated to the arrangement section 136 in the conductive ribbon 132 is supplied to the antenna 270 by electric field coupling, magnetic field coupling, radio wave transmission and reception, or a combination of these. The electromagnetic energy supplied to the antenna 270 is supplied to a demodulation circuit (not shown) as a high-frequency signal including tag information. The demodulation circuit demodulates the supplied high-frequency signal and acquires the tag information. The tag information acquired by the demodulation circuit is supplied to the control unit 210.

[0072] Here, the wearable item 100 employs a structure to improve the accuracy of reading tag information. The structure of the wearable item 100 around the placement section 136 will be described below. Figure 10 shows a cross-sectional view of line A-A in Figure 9. In Figure 10, components that have little effect on radio waves have been omitted as appropriate to facilitate understanding. Figure 11 shows the arrangement order, materials, etc. of the components present in the cross-section of line A-A. In Figure 10, back of hand 610 is the back of the user's left hand.

[0073] The antenna 270 included in the reader / writer 200 is disposed inside a housing 280 included in the reader / writer 200 so as to face the conductive ribbon 132. The shield 162 included in the covering unit 160 is wound around an axis extending in the Y-axis direction so as to collectively cover the antenna 270, the conductive ribbon 132, and the shield 138. The shield 138 included in the mounting unit 110 is disposed so as to face the conductive ribbon 132 so as to sandwich the conductive ribbon 132 between the antenna 270 and the shield 162.

[0074] The shield 162 blocks the transmission of electromagnetic energy to other wireless tags and blocks the transmission of electromagnetic energy from other wireless tags to the antenna 270. The reason for this will be explained below. The other wireless tags are wireless tags that are not the target for reading tag information. On the other hand, the wireless tag 400 is the target for reading tag information. First, the shield 162 is arranged in any of the positive direction of the X axis, the negative direction of the X axis, the positive direction of the Z axis, and the negative direction of the Z axis when viewed from the antenna 270. Therefore, if another wireless tag is arranged in these directions, the transmission of electromagnetic energy is blocked by the shield 162.

[0075] In particular, a double shield 162 is arranged in the positive direction of the Z axis as viewed from the antenna 270. Therefore, reading of tag information from other wireless tags arranged in the positive direction of the Z axis as viewed from the antenna 270 is sufficiently suppressed. On the other hand, the back of the user's hand is arranged in the negative direction of the Z axis as viewed from the antenna 270. Therefore, reading of tag information from other wireless tags arranged in the negative direction of the Z axis as viewed from the antenna 270 is also sufficiently suppressed.

[0076] Furthermore, because antenna 270 extends in a direction perpendicular to the Z-axis direction, it is difficult to radiate radio waves in any of the positive X-axis direction, the negative X-axis direction, the positive Y-axis direction, and the negative Y-axis direction. Therefore, even if other wireless tags are placed in the positive Y-axis direction and the negative Y-axis direction as viewed from antenna 270, electromagnetic energy is unlikely to be transmitted from antenna 270 to the other wireless tags.

[0077] On the other hand, the shielding body 162 does not block the transmission of electromagnetic energy to the wireless tag 400, which is the wireless tag whose tag information is to be read, and does not shield the antenna 270 from the wireless tag 400. The reason for this will be explained below. First, the reader / writer 200 uses the antenna 270 to transmit electromagnetic energy to the antenna 440 provided in the wireless tag 400 via the conductive ribbon 132.

[0078] Here, the shield 162 is wrapped around the antenna 270 and the conductive ribbon 132 so as to cover them together, and is not disposed on the transmission path of electromagnetic energy from the antenna 270 to the antenna 440. Therefore, the transmission of electromagnetic energy from the antenna 270 to the antenna 440 is not blocked by the shield 162. For this reason, according to this embodiment, pinpoint reading, that is, reading of tag information from only the wireless tag 400, is possible. Note that the shield 162 is disposed so as not to cover the entire reader / writer 200. Therefore, the shield 162 does not impede wireless communication between the reader / writer 200 and the control device 500.

[0079] Here, if the distance between the shielding body 162 and the antenna 270 is too close, it may become impossible to achieve impedance matching of the antenna 270, which may reduce the coupling efficiency between the antenna 270 and the conductive ribbon 132. Therefore, it is preferable that the distance between the shielding body 162 and the conductive ribbon 132 is not too close. For example, it is preferable that the distance between the shielding body 162 and the conductive ribbon 132 be 9 mm or more.

[0080] The shield 138 is provided to adjust the strength of the electromagnetic coupling between the antenna 270 and the placement portion 136 on the conductive ribbon 132. The reason why the shield 138 is necessary will be explained below. If the electromagnetic coupling between the antenna 270 and the placement portion 136 is too weak, it will be difficult to read tag information from the wireless tag 400 placed near the reading portion 135 on the conductive ribbon 132.

[0081] On the other hand, if the electromagnetic coupling between the antenna 270 and the placement section 136 is too strong, electromagnetic energy may be radiated into space from the conductive ribbon 132, potentially resulting in erroneous reading of tag information. For example, if this electromagnetic coupling is too strong, there is a possibility that tag information may be erroneously read from another wireless tag placed near the middle portion of the conductive ribbon 132. The middle portion is the portion of the conductive ribbon 132 between the placement section 136 and the reading section 135. Here, it is often not possible to finely adjust the strength of the radio waves radiated from the antenna 270 by the reader / writer 200. Therefore, it is preferable to use a shield 138 to appropriately weaken the electromagnetic coupling between the antenna 270 and the placement section 136.

[0082] The shield 138 is disposed parallel to the placement portion 136 of the conductive ribbon 132 so as to face the placement portion 136. Here, the shorter the distance between the shield 138 and the placement portion 136, the weaker the electromagnetic coupling between the antenna 270 and the placement portion 136. Therefore, it is preferable to appropriately adjust the distance between the shield 138 and the placement portion 136 to appropriately weaken this electromagnetic coupling. Note that instead of disposing the shield 138 near the placement portion 136, there is a method of moving the shield 162 closer to the placement portion 136. With this method, the distance between the shield 162 and the placement portion 136 may vary, and therefore it may not be easy to adjust the strength of the electromagnetic coupling between the antenna 270 and the placement portion 136.

[0083] Next, the structure of the area surrounding the reading unit 135 in the wearable item 100 will be described. Fig. 12 shows a cross-sectional view taken along line B-B in Fig. 9. To facilitate understanding, Fig. 12 only shows the components located below finger 620, which is the index finger of the user's left hand. Fig. 13 shows the arrangement order, materials, etc. of the components present in the cross-section taken along line B-B.

[0084] When reading tag information, the user brings the index finger of their left hand close to the wireless tag 400 so that the reading unit 135 of the conductive ribbon 132 faces the antenna 440 of the wireless tag 400. This enables electromagnetic energy to be transmitted between the reading unit 135 and the antenna 440, making it possible to read the tag information.

[0085] Here, if a human body or an object is present near the conductive ribbon 132, electromagnetic energy propagating near the conductive ribbon 132 propagates inside the human body or object. In this case, the electromagnetic energy is attenuated by dielectric loss due to the electrical characteristics of the human body or object, i.e., the dielectric constant and dielectric dissipation factor of the human body or object. The degree of this attenuation is greater the larger the dielectric constant and dielectric dissipation factor. Therefore, in order to reduce the attenuation of electromagnetic energy, it is desirable to prevent a human body with a relatively large dielectric constant and dielectric dissipation factor, and an object with a large dielectric constant and dielectric dissipation factor, from being placed near the conductive ribbon 132.

[0086] Therefore, in this embodiment, a member having a small dielectric constant and dielectric dissipation factor and a certain thickness is placed between the conductive ribbon 132 and the human body. Such a member is preferably made of a material having a small dielectric constant and dielectric dissipation factor, and has a structure having a small dielectric constant and dielectric dissipation factor. Examples of materials having a small dielectric constant and dielectric dissipation factor include polyolefin and polyester. Examples of structures having a small dielectric constant and dielectric dissipation factor include a three-dimensional structure, such as a double Russell knit structure, and a porous structure.

[0087] In the present embodiment, since members 113, 137, etc. are provided as such members, it is possible to reduce the attenuation of electromagnetic energy due to the human body, members 113, 137, etc. It is preferable that the distance between conductive ribbon 132 and the human body be 3 mm or more.

[0088] In this embodiment, covering section 160 that covers storage section 150 includes shielding body 162 that is formed in a sheet shape and covers at least the entire circumference of storage section 150. Shielding body 162 prevents tag information from being read from other wireless tags that are not the target for tag information reading. Therefore, this embodiment provides high accuracy in reading tag information.

[0089] Furthermore, in this embodiment, the shield 162 is disposed twice on the opposite side of the reader / writer 200 from the part of the user's body. Therefore, according to this embodiment, reading of tag information from another wireless tag disposed on the opposite side of the reader / writer 200 from the part of the user's body is sufficiently suppressed.

[0090] Furthermore, in this embodiment, the covering section 160 is arranged so that the shielding body 162 collectively covers the storage section 150 and the arrangement section 136 of the conductive ribbon 132. Therefore, according to this embodiment, it is possible to maintain the reading of tag information from the wireless tag 400 while suppressing the reading of tag information from other wireless tags.

[0091] Furthermore, in this embodiment, the mounting unit 110 includes a sheet-like shield 138 disposed so as to sandwich the placement portion 136 of the conductive ribbon 132 between the mounting unit 110 and the reader / writer 200. The shield 138 adjusts the strength of the electromagnetic coupling between the placement portion 136 and the antenna 270. Therefore, according to this embodiment, it is possible to maintain the reading of tag information from the wireless tag 400 while suppressing the reading of tag information from other wireless tags.

[0092] Furthermore, in this embodiment, the covering section 160 is arranged so that the shielding body 162 collectively covers the storage section 150, the arrangement section 136 of the conductive ribbon 132, and the shielding body 138. Therefore, according to this embodiment, it is possible to maintain the reading of tag information from the wireless tag 400 while suppressing the reading of tag information from other wireless tags.

[0093] Furthermore, in this embodiment, shield 162 is wrapped around storage section 150 so as not to cover the side surfaces of storage section 150. Therefore, according to this embodiment, when reader / writer 200 is stored in storage section 150, it is possible to operate operation reception section 240 via opening 152, charge via opening 152, communicate wirelessly between reader / writer 200 and control device 500, and check display section 230 via opening 153.

[0094] In addition, in this embodiment, the conductive thread 133 is arranged in a meandering pattern. Therefore, according to this embodiment, the electromagnetic coupling between the conductive thread 133 and the antenna 270 is strong, and radiation of radio waves from the conductive thread 133 in the intermediate portion between the reading unit 135 and the placement unit 136 is reduced.

[0095] In this embodiment, the distance between the conductive thread 133 and the human body is 3 mm or more. Therefore, according to this embodiment, the propagation loss due to the human body is reduced.

[0096] In addition, in this embodiment, the distance between the conductive thread 133 and the shield 162 is 9 mm or more. Therefore, according to this embodiment, a decrease in the coupling efficiency between the conductive thread 133 and the antenna 270 is suppressed, and a decrease in the accuracy of reading tag information is reduced.

[0097] In this embodiment, the member 113 that comes into contact with the human body is made of double-russell knitted ultra-fine polyester fibers that have a high static friction resistance. Therefore, this embodiment prevents misalignment of the reading unit 135 and the reader / writer 200, thereby improving operability and comfort during work.

[0098] In this embodiment, the wearable item 100 is worn on the non-dominant hand, so that the wearable item 100 can be used to perform other tasks with the dominant hand.

[0099] Furthermore, in this embodiment, tag information can be read simply by inserting the reader / writer 200 into the storage section 150 of the wearable item 100, and no connection using a connector is required. That is, in this embodiment, the reader / writer 200 can be easily attached to and detached from the wearable item 100. Therefore, according to this embodiment, the effort required to wash the wearable item 100 is reduced, for example.

[0100] (Embodiment 2) In the first embodiment, an example in which the storage unit 150 is placed on the back of the user's hand has been described. In the present embodiment, an example in which the storage unit 150A is placed on the user's wrist will be described. Hereinafter, descriptions of configurations or functions similar to those in the first embodiment will be omitted or simplified as appropriate.

[0101] Fig. 14 shows a side view of the wearable item 100A according to this embodiment. Fig. 15 shows a top view of the wearable item 100A according to this embodiment. Fig. 16 shows a first external view of the wearable item 100A according to this embodiment when worn. Fig. 17 shows a second external view of the wearable item 100A according to this embodiment when worn. The external view shown in Fig. 16 is an external view of the wearable item 100A worn on the user's hand when viewed from the back of the user's hand. The external view shown in Fig. 17 is an external view of the wearable item 100A worn on the user's hand when viewed from the palm of the user's hand.

[0102] The wearable item 100A is an item that is worn on a part of the user's body and is used to fix the reader / writer 200 to the part of the user's body. The wearable item 100A has a function of storing the reader / writer 200 and a function of propagating radio waves used by the reader / writer 200. The wearable item 100A includes a mounting section 110A, a storage section 150A, and a covering section 160A.

[0103] The wearing unit 110A is a member that is worn on a part of the user's body. In this embodiment, the wearing unit 110A is worn on the user's non-dominant hand. The wearing unit 110A includes a member 111A, a metal fitting 112A, and a ribbon 130A.

[0104] Member 111A is a belt-shaped member for fastening storage unit 150A to the user's wrist. One end of member 111A is fixed to one end of the bottom surface of covering unit 160A. The other end of member 111A is inserted into a slit-shaped opening (not shown) provided in metal fitting 112A and fixed to the other end of member 111A. For example, the other end of member 111A is fixed by a pair of hook-and-loop fasteners (not shown) arranged on one surface of the other end of member 111A.

[0105] The metal fitting 112A is a metal fitting for fixing the other end of the member 111A to the other end of the bottom surface of the covering part 160A. The metal fitting 112A is fixed to the other end of the bottom surface of the covering part 160A. The metal fitting 112A has a slit-shaped opening into which the member 111A is inserted.

[0106] The ribbon 130A is a band-shaped member that increases the degree of freedom in the tag information reading position. The ribbon 130A is appropriately fixed to the user's body so that tag information can be read at a location desired by the user. For example, the ribbon 130A is hooked between the user's fingers when the wearable item 100A is worn. The ribbon 130A may be hooked between any of the fingers. In the present embodiment, the ribbon 130A is hooked between the index finger and middle finger. In this case, tag information can be read at the part of the palm that connects the wrist and the space between the index finger and middle finger. When the ribbon 130A is hooked between the fingers, the ribbon 130A is fixed to the user's hand, and the tag information reading position is determined. Note that the ribbon 130A does not have to be hooked between the fingers. For example, the ribbon 130A may be wrapped around the wrist, overlapping the covering portion 160A.

[0107] One end of ribbon 130A is fixed to the bottom of storage section 150A. The other end of ribbon 130A is fixed to the other surface of the other end of member 111A. For example, a hook-and-loop fastener (not shown) arranged on one surface of the other end of ribbon 130A and a hook-and-loop fastener (not shown) arranged on the other surface of the other end of member 111A are fastened to each other.

[0108] The ribbon 130A includes a conductive ribbon 132A and a non-conductive ribbon 137A. The conductive ribbon 132A is a member for propagating radio waves used for reading tag information by the reader / writer 200. The conductive ribbon 132A is a flat, elongated member that has been given conductivity. The conductive ribbon 132A propagates radio waves used for reading tag information between the reading unit 135A and the placement unit 136A. The reading unit 135A is a portion of the conductive ribbon 132A that is brought close to the wireless tag 400 to read the tag information. The placement unit 136A is a portion of the conductive ribbon 132A where the reader / writer 200 is placed. The ribbon 130A is an example of a strip-shaped member.

[0109] The conductive ribbon 132A includes a conductive thread 133A and a member 134A. The conductive thread 133A is basically the same member as the conductive thread 133. That is, the conductive thread 133A is a thread-like member that is conductive. The member 134A is basically the same member as the member 134. That is, the member 134A is a band-like member to which the conductive thread 133A is attached. In the conductive ribbon 132A, the conductive thread 133A is arranged in a meandering shape. The conductive ribbon 132A is an example of a propagation section.

[0110] The non-conductive ribbon 137A is a flat, elongated member that is not provided with conductivity. In the present embodiment, the non-conductive ribbon 137A is a strip-shaped elastic member that has elasticity. The elasticity of the non-conductive ribbon 137A allows the ribbon 130A to be firmly fixed to the user's hand. The non-conductive ribbon 137A is made of, for example, rubber. The non-conductive ribbon 137A is an example of an elastic member. Note that the non-conductive ribbon 137A may also be a member that does not have elasticity. For example, the non-conductive ribbon 137A may be a fabric that does not have elasticity. Furthermore, the non-conductive ribbon 137A may also be a hook-and-loop fastener for fixing the ribbon 130A.

[0111] As described above, mounting unit 110A has a fixing function for fixing storage unit 150A and a propagation function for propagating radio waves. The fixing function is mainly realized by member 111A. The propagation function is realized by ribbon 130A having conductive ribbon 132A. Mounting unit 110A is an example of a mounting unit.

[0112] The storage unit 150A basically has the same configuration and function as the storage unit 150. In other words, the storage unit 150A is a member that is fixed to the attachment unit 110A and that stores the reader / writer 200 that reads tag information from the wireless tag 400. The storage unit 150A is placed on the user's wrist when the wearable item 100A is attached. The storage unit 150A is an example of a storage unit.

[0113] The covering unit 160A basically has the same configuration and function as the covering unit 160. In other words, the covering unit 160A is a member that covers the storage unit 150A. Like the covering unit 160, the covering unit 160A includes a first shield (not shown) that is formed in a sheet shape and covers the storage unit 150A. Also, like the mounting unit 110, the attachment unit 110A includes a second shield (not shown). The second shield is formed in a sheet shape and is arranged so as to sandwich the placement unit 136A between the reader / writer 200. The covering unit 160A is arranged so that the first shield collectively covers the storage unit 150A, the placement unit 136A, and the second shield. The covering unit 160A is an example of a covering unit.

[0114] This embodiment basically provides the same effects as those of embodiment 1. For example, in this embodiment, covering portion 160A that covers storage portion 150A includes a first shield that is formed in a sheet shape and covers at least one periphery of storage portion 150A. Therefore, this embodiment provides high accuracy in reading tag information.

[0115] In this embodiment, the mounting unit 110A includes a ribbon 130A formed in a strip shape and including a conductive ribbon 132A. According to this embodiment, it is possible to increase the degree of freedom in the position where tag information is read.
