Abstract

PROBLEM TO BE SOLVED: To provide a non-contact identification band configured to prevent electric waves from being absorbed or attenuated by moisture in the body of a person wearing the band, to improve access detection accuracy using an identification tag, and non-contact identification parts.SOLUTION: Antenna elements of two RF tags are arranged so as to be extended in a circumferential direction of a body section wearing an identification band. Thus, even when an antenna element of one RF tag is orthogonal, or in a similar posture, with respect to a R/W antenna 50, and a read-write distance is reduced, an antenna element of the other RF tag axially faces the R/W antenna 50 or is in the similar posture. Reduction in a read-write distance and accuracy of the RF tag can be prevented as a whole of the identification band, accordingly. The two RF tags are distant from body moisture in the body section wearing the identification band by a thickness of an elastic cushioning member, thereby preventing electric waves transmitted to/received from the RF tag from being absorbed or attenuated by moisture in the body of a person wearing the band.SELECTED DRAWING: Figure 6

Description

  The present invention relates to a non-contact type identification band used in an entry / exit management system for managing the entry / exit of a managed person and a non-contact type identification part for producing the non-contact type identification band.

  An entrance / exit management system using an RFID system attaches an RF tag (also referred to as an IC tag), which is a type of identification tag that stores unique identification information, to a managed person, while the facility used by the managed person. Reader / writers (hereinafter sometimes abbreviated as “R / W”) antennas as detection antennas are installed on both sides of the entrance / exit passage, and an RF reader / writer is connected to each R / W antenna. This is a system in which a reader / writer is connected to a management computer. The direction of the electric field radiated from the R / W antenna may be linearly polarized or circularly polarized.

  According to this entrance / exit management system, when the managed person passes through the entrance / exit of the use facility and exits the facility without permission, the identification information of the RF tag attached to the managed person is displayed on the R / W antennas on both sides of the entrance / exit. Is read by the RF reader / writer and transmitted to the management computer, so that the administrator who monitors the management computer is notified. It can be detected that the user has left without permission.

  For example, in such an entry / exit management system, an RF tag storing identification information of a managed person is attached to a wearing band such as a wristband, and this wearing band is a part of the body of the managed person, such as a wrist or the like. The entrance / exit of the managed person is managed by being wound around the attached part.

  As such an entry / exit management system, there is an RFID system that uses radio wave communication in the UHF (ultra-high frequency) band (for example, 920 MHz band). In this UHF band RFID system, an RF tag antenna element and an RF reader / writer R / W antenna perform radio communication using UHF band radio waves.

  The UHF band RF tag includes an antenna element having an antenna length for transmitting and receiving a UHF band radio wave, and an IC chip to which the antenna element is connected. A memory in which identification information unique to the tag is stored is incorporated.

  The UHF band RF tag includes a read / write distance (read distance and write distance) between the R / W antenna and the RF tag, as compared with an HF (short wave) band (13.56 MHz band) that performs radio communication by an electromagnetic induction method. ) Is long, and the influence of the orientation of the antenna element of the RF tag with respect to the R / W antenna on the read / write distance is small.

Japanese Patent No. 5511215

  The wristband equipped with the UHF band RF tag described above is the wrist of the manager to be worn, but the wristband rotates around the wrist and causes a deviation in the tuning of the antenna element of the UHF band RF tag. If the wristband is not tightly fixed to the wrist so that the UHF band RF tag is not misaligned, detection by the R / W antenna of the UHF band RF tag becomes difficult.

  However, if the wristband is attached to the human body to fix it to the wrist, for example, in the case of an adult, the radio waves transmitted and received by the UHF band RF tag are reflected and attenuated by the body moisture contained in the body, and the UHF band When the read / write distance of the RF tag is significantly reduced, there is a problem.

It is possible to reduce the absorption and attenuation of radio waves.

  Further, the antenna elements of the two identification tags extend in the longitudinal direction of the two identification tags, and the two identification tags are adjacent to each other with the longitudinal directions thereof aligned and adjacent to each other. Since the band member or the base member is juxtaposed with the band member or the base member with an interval shorter than the entire length of the element, the band member or the base member is wound around the mounted portion, so that The antenna elements of the identification tag can be extended in a lined state.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings.

<Entry / exit management system>
FIG. 1 is an explanatory diagram showing an installation state of an R / W antenna 60 in relation to an entrance / exit management system using an RFID system using an identification band 10 which is an embodiment of a contactless identification band of the present invention. FIG. 2 is a schematic plan view of a facility entrance 100 where an R / W antenna 60 is installed.

  As shown in FIG. 1, one R / W antenna 60 is installed on both sides of the passage 101 of the facility entrance 100 to perform communication with the RF tag 2 (see FIG. 3) in a wireless manner. These two R / W antennas 60 are arranged to face each other. Each R / W antenna 60 is communicably connected to an RF reader / writer (not shown), and this RF reader / writer is connected to a management computer. Here, the distance between the R / W antennas 60 is, for example, about 1.5 m.

  In addition, in this entrance / exit management system, it is also possible that a plurality of managed persons pass through the facility entrance / exit 100 at the same time without permission, and therefore the identification information of the plurality of RF tags 2 is obtained via the R / W antenna 60. An anti-collision type RF reader / writer having a function capable of simultaneously reading (a plurality of simultaneous reading functions) is used. The direction of radio waves (electromagnetic waves) radiated from the R / W antenna 60 may be either linearly polarized waves or circularly polarized waves.

<Identification parts>
FIG. 2 is an explanatory view of an identification part 1 which is an embodiment of the non-contact type identification part of the present invention, FIG. 2 (a) is a plan view of the identification part 1, and FIG. FIG. 2C is a front view in which the identification part 1 is disassembled into each member, FIG. 2D is a bottom view of the identification part 1, and FIG. ) Is an enlarged partial sectional view taken along line E2-E2 of FIG.

  As shown in FIG. 2, the identification part 1 is attached to the wearing band 7 wound around the wearing portion 70 (see FIGS. 1 and 6) of the wearer who is a management person and attached to the identification band 10 (FIG. 5). 2), and mainly includes two RF tags 2, a base member 3, an elastic buffer member 4, and a contact member 5.

<RF tag>
The two RF tags 2 are formed in a rectangular sheet shape having flexibility and flexibility (see FIG. 2A and FIG. 5), and are wound around the attachment site 70 (see FIG. 2). 6), it can be curved and deformed along the outer periphery of the attachment site 70. These two RF tags 2 have a function of communicating various information with the R / W antenna 60 by a radio wave system, and both are formed of the same type of IC tag.

  Each RF tag 2 of the present embodiment is compatible with the UHF band in which the frequency band of communication radio waves is the UHF band (mainly the 920 MHz band). The RF tag 2 is a passive tag, and generates drive power in the IC tag by electromagnetic waves (radio waves) radiated from the RF reader / writer. Note that the RF tag 2 of this embodiment has a reading distance corresponding to a specific low power and a maximum of about 2.5 m, and a writing distance is about 70% of the reading distance. Hereinafter, the reading distance and the writing distance are collectively referred to as a reading / writing distance.

  Each RF tag 2 has its outer peripheral portion shown in FIG. 2A fixed to the lower surface of the base member 3 by welding (fusion). Further, these two RF tags 2 are arranged in a line in the longitudinal direction of the base member 3 in a state where the longitudinal directions of the two RF tags 2 coincide with each other. However, the interval between two RF tags 2 is shorter (for example, about 16 mm) than the total length La (for example, about 95 mm) (see FIG. 3) of its own antenna element 2b (hereinafter referred to as “tag interval”). Ct is provided.

  As described above, the two RF tags 2 are arranged adjacent to each other while aligning the longitudinal directions thereof, but the tag interval Ct for reducing the power sharing phenomenon is provided between the two RF tags 2. Thus, it is possible to suppress a decrease in the read / write accuracy of each RF tag 2.

  Here, the power sharing phenomenon is a phenomenon in which, when two or more RF tags 2 are close to each other, the specific RF tag 2 strongly absorbs the radiated radio wave of the R / W antenna 60. When the RF tags 2 are arranged close to each other, adjacent RF tags 2 share the electric field existing in the vicinity, so that the electric field received by each RF tag 2 decreases and the read / write distance decreases. . For this reason, there is a difference in the density of the radiated radio wave between the RF tags 2, and the RF tag 2 that cannot sufficiently receive the radiated radio wave appears.

  Further, the degree of the power sharing phenomenon greatly depends on the total length La of the antenna element 2b of the adjacent RF tag 2. For example, since many of the UHF band RF tags 2 use the antenna element 2b corresponding to a quarter wavelength, a plurality of antenna elements 2b in the same communication frequency band are at a distance of a quarter wavelength of the radiated radio wave. It is also said that the plurality of antenna elements 2b are generated by exchanging radio wave energy when they are adjacent to each other.

  In addition, in the entrance / exit management system using the identification band 10 of the present embodiment, the method of intermittently radiating the radiated radio wave (electromagnetic wave) from the R / W antenna 60 is also used in combination, thereby reducing the influence of the power sharing phenomenon. As a result, even when a plurality of RF tags 2 are adjacent to each other, the read / write accuracy of each RF tag 2 is further improved.

  FIG. 3 is a plan view of the RF tag 2 used in the present embodiment, and shows a state in which the internal structure is seen through. In the figure, the welded portion when the RF tag 2 is welded to the base member 3 is hatched.

  As shown in FIG. 3, the RF tag 2 is obtained by encapsulating a tag inlay in which an IC chip 2a and an antenna element 2b are arranged on a film substrate with a covering 2c. An outer peripheral portion (shaded portion in FIG. 3) avoiding locations where electronic components such as the IC chip 2 a and the antenna element 2 b are disposed in the covering body 2 c is welded and fixed to the base member 3.

  In addition, the RF tag 2 of the present embodiment is formed in a rectangular shape in plan view of 10 mm length × 95 mm width.

  The IC chip 2a mainly includes a CPU for performing various arithmetic processes, a memory for storing identification information (ID information) unique to the managed person (wearer), an RF reader / writer via the R / W antenna 60, And a communication circuit for performing wireless communication processing.

  The antenna element 2b is a pair of dipole antennas electrically connected to the communication circuit of the IC chip 2a, and transmits and receives radio waves for radio communication with the RF reader / writer. The RF tag 2 has an antenna element 2b extending in the longitudinal direction.

  This RF tag 2 uses a laundry tag (linen tag) having resistance to washing processing, and this laundry tag is a tag inlay sealed and encapsulated by a flexible and flexible covering 2c. The covering body 2c has waterproofness, durability and other resistances required at the time of washing.

  Since each RF tag 2 is formed with a laundry tag in this way, a managed person (wearer) enters a bathing facility such as a medical facility or a nursing facility, a pool facility, or other facility that uses water, and the identification band 10 Even if submerged, each RF tag 2 can be prevented from malfunctioning due to such submergence. Moreover, even if the wearer uses it roughly, each RF tag 2 has durability, so that it is possible to prevent the IC chip 2a and the antenna element 2b built therein from being damaged.

  Here, since the antenna element 2b of the RF tag 2 of the present embodiment is a pair of dipole antennas extending from the center of the RF tag 2 in both longitudinal directions, the total length of the antenna element 2b of the RF tag 2 (Antenna length) La is the length from the end of one antenna element 2b (2b1) to the end of the other antenna element 2b (2b2).

The virtual center axis Mc of the antenna element 2b of the RF tag 2 described later is an axis passing through the center of the entire length La and width W of the antenna element 2b and is a vertical axis with respect to the surface 2b3 of the antenna element 2b.
<Base member>
As shown in FIG. 2, the base member 3 is an elongated belt-like sheet body having flexibility and flexibility, and is attached to a mounting band 7 (see FIGS. 4, 5, and 6) described later. By being integrated, the band member of the identification band 10 that can be wound around the attachment site 70 is obtained. When the base member 3 is wound around the attachment site 70 as a band member, the base member 3 can be curved and deformed along the outer periphery of the attachment site 70.

  Specifically, the base member 3 is formed by molding a thermoplastic elastomer such as a polyurethane elastomer into a sheet shape. This thermoplastic elastomer is a polymer material that has both the elasticity similar to that of a rubber elastic body at room temperature and the property of being plasticized (softened) and processed by heating.

  The base member 3 mainly includes a band contact portion 3a and a band extension portion 3b. The band attachment portion 3a is a portion where the attachment member 5 is disposed for attaching and fixing the base member 3 to the inner peripheral surface of the attachment band 7, and the attachment member 5 is disposed on the upper surface of the band attachment portion 3a. 5 is stuck and fixed. The band extension part 3 b is connected to one end of the band contact part 3 a and is a part for extending the length of the mounting band 7.

  The band extension 3b of the present embodiment is a kind of the mounting band 7, and the length of a relatively short mounting band 7 such as an off-the-shelf wristband wound around the wrist is set like an ankle band. This is a portion for extending the length of the mounting band 7 to a length that can be wound around the mounted portion 70 in order to be diverted to the relatively long mounting band 7.

  The two RF tags 2 described above are fixed to the lower surface of the base member 3 by welding in a state where the longitudinal directions of the RF tags 2 coincide with the longitudinal direction of the base member 3. In addition, the base member 3 of a present Example is a size of length 275mm, width 15mm, and thickness 0.3mm, for example.

  Here, one RF tag 2 is fixed to a lower surface of the band attaching portion 3 a and corresponding to a portion immediately below the attaching member 5. Further, most of the other RF tag 2 is fixed to the lower surface of the band extension portion 3b, but one end portion thereof is disposed so as to straddle the band attaching portion 3a. Further, the other RF tag 2 is disposed from the base end portion of the band extension portion 3b to the front portion of the band extension portion 3b.

  Further, of the non-arranged portions of the two RF tags 2 in the base member 3, a portion having a tag interval Ct in the middle portion in the longitudinal direction of the base member 3 has a cylindrical shape that is an intermediate engaging portion of the base member 3. Are provided with two intermediate projections 3c and two distal end holes 3d as distal end engaging portions at the distal end of the band extension 3b.

  The two intermediate projections 3c on the base member 3 are two columnar pieces that can be engaged with the two engagement holes 7a (see FIG. 4A) originally provided at one end of the mounting band 7 in the longitudinal direction. These protrusions are arranged adjacent to each other in the longitudinal direction of the base member 3.

  On the other hand, the two front end holes 3d in the base member 3 are formed corresponding to the interval between the 15 engagement holes 7a (see FIG. 4A) originally on the other end side of the mounting band 7. The two through holes are arranged adjacent to each other in the longitudinal direction of the base member 3.

<Elastic cushioning member (Example 1)>

  The elastic buffer member 4 is formed of an elastic structure having a predetermined thickness, and has an air enclosing portion in the elastic structure. The elastic buffer member 4 is formed in a long rectangular parallelepiped shape, and its upper surface is fixed to the lower surface of the base member 3 by a fixing member 6. The fixing member 6 is formed of a double-sided pressure-sensitive adhesive tape having water-resistant strong adhesive surfaces on both sides.

  The elastic shock-absorbing member 4 having the air inclusion part sandwiches the two RF tags 2 between the base member 3. The elastic shock-absorbing member 4 is formed to be larger than the length and width of the portion where the RF tag 2 having two lengths and widths is disposed, and covers the entire lower surface of the two RF tags 2. .

  For this reason, the elastic shock-absorbing member 4 is attached to both of the two RF tags 2 in a state where the base member 3 is wound around the attachment site 70 by winding the identification band 10 around the attachment site 70. It looks like it is interposed between the mounting part 70 (see FIG. 6). Accordingly, both of the two RF tags 2 are separated from the moisture in the body 70 to be attached by the thickness of the elastic buffer member 4, and there is an air enclosing portion inside the elastic buffer member 4. It is possible to prevent radio waves transmitted and received by the individual RF tags 2 from being absorbed or attenuated by moisture in the wearer's body.

  The thickness of the elastic buffer member 4, that is, the distance between the two RF tags 2 and the attachment site 70 is determined between the R / W antennas 60 (for example, R / W) disposed on both sides of the passage 101 of the facility entrance 100. It is set so that data can be read from and written to the two RF tags 2 in a state in which the identification band 10 is attached to the attachment site 70 of the management person passing a distance 1.5 m) between the W antennas 60. .

  Moreover, the elastic structure which forms the elastic buffer member 4 has a non-water-absorbing structure of water which is going to enter the air enclosing part. This elastic structure is an elastic foam having a closed cell structure in which a large number of fine closed cells (not shown) are uniformly formed. According to this elastic structure, air inclusions are formed by the large number of independent bubbles, and since each bubble is independent in a non-communication state, it is possible to prevent water from penetrating into the air inclusions. .

  For example, this elastic structure is formed of an elastically deformable elastic foam material such as highly foamed polyurethane or highly foamed polyethylene, and when the elastic buffer member 4 is wound around the attached portion 70, the attached portion It can be curved and deformed along the outer periphery of 70. Moreover, since the elastic cushioning member 4 is formed of a flexible elastic foam, it is possible to reduce the wearer's uncomfortable feeling due to contact with the attachment site 70.

  Further, since the elastic cushioning member 4 directly contacts the skin of the attachment site 70 during normal use of the identification band 10, an elastic foam material having a property that does not corrode and irritate the skin is used. Furthermore, this elastic foam material has neither serious eye damage nor eye irritation, nor respiratory sensitization or skin sensitization.

<During member>
The contact member 5 is for attaching the base member 3 to the inner peripheral surface of the mounting band 7, and is fixed to the band contact portion 3 a of the base member 3. The contact member 5 is, for example, a double-sided pressure-sensitive adhesive tape in which water-resistant strong adhesive surfaces are formed on both sides. The adhesive surface on the lower surface of the contact member 5 is attached to the upper surface of the base member 3, and the adhesive surface on the upper surface of the contact member 5 is covered with release paper. By peeling off the release paper, the adhesive surface on the upper surface of the contact member 5 is adhered to the inner peripheral surface of the mounting band 7.

<Mounting band and engagement tool>

  As shown in FIG. 4A, the mounting band 7 has a plurality of engaging holes 7a as engaging portions at one end and the other end in the longitudinal direction. The plurality of engagement holes 7 a are through holes for connecting the both ends of the attachment band 7 using the engagement tool 8 in order to make the attachment band 7 an annular body.

  Specifically, two engagement holes 7a are arranged adjacent to each other in the longitudinal direction of the mounting band 7 at one end in the longitudinal direction of the mounting band 7, and the other end in the longitudinal direction of the mounting band 7 ( Fifteen engagement holes 7a are formed in a line in the longitudinal direction of the mounting band 7 in the vicinity of each other at a portion extending from the other end portion of the mounting band 7 to the intermediate portion. Further, all these engagement holes 7 a are formed on the center line in the width direction of the mounting band 7.

  As shown in FIG. 4B, the engaging tool 8 includes a protruding plate portion 8a having a pair of locking protrusions 8a1 and a hole having a substantially “8” shape in plan view having a pair of locking holes 8b1. The plate portion 8b is connected to the bent portion 8c. The engaging tool 8 in the state of FIG. 4 (b) is bent at the bent portion 8c as shown in FIG. 4 (c) so that the projecting plate portion 8a and the hole plate portion 8b face each other face to face. Thus, the pair of locking projections 8a1 are respectively engaged in the locking holes 8b1, and the projecting plate portion 8a and the hole plate portion 8b are coupled to face each other.

  According to this engagement tool 8, in the unfolded state shown in FIG. 4 (b), the pair of locking projections 8a1 are passed through the two through holes formed in the mounting band 7 and the identification band 10, and FIG. c), the bent portion 8c is bent so that the mounting band 7 and the identification band 10 are sandwiched between the protruding plate portion 8a and the hole plate portion 8b, and the respective locking projections 8a1 are engaged with the respective locking holes 8b1. By inserting, the protruding plate portion 8a and the hole plate portion 8b are combined with the mounting band 7 and the identification band 10 between the protruding plate portion 8a and the hole plate portion 8b, and attached to the mounting band 7 and the identification band 10. (See FIG. 6).

<Identification band>

FIG. In FIG. 5A, the RF tag 2 is hatched for the sake of convenience in order to make it easy to identify the position where the RF tag 2 is disposed.

  As shown in FIG. 5, the identification band 10 has the inner peripheral surface of the mounting band 7 overlapped with the band contact portion 3 a of the base member 3, and the two intermediate protrusions 3 c of the base member 3 are arranged in the longitudinal direction of the mounting band 7. One end of the mounting band 7 is engaged with the intermediate portion of the base member 3 by engaging with the two engagement holes 7a at one end in the direction, and the band attachment of the base member 3 is caused by the engagement. The portion 3a is positioned at an appropriate position on the mounting band 7. By positioning using the intermediate protrusion 3 c, the band contact portion 3 a of the base member 3 can be easily aligned with an appropriate position of the mounting band 7.

  Here, the identification band 10 of this embodiment is applied to an ankle band attached to the ankle, and the two RF tags 2 are formed to be attached to the ankle away from the wearer's torso. Is.

  In this way, by making the identification band 10 an ankle band, the RF tag 2 becomes a shadow of the torso of the person to be managed, as in the case where the RF tag 2 is attached to the wristband (see FIG. 4), The RF tag 2 is brought into close contact with the body of the person to be managed by putting hands or arms in the pocket, or is affected by body moisture, or the RF tag 2 becomes a shadow of luggage held in the hand. Various problems can be reduced, and the RF tag 2 can be prevented from being detected by the R / W antenna 60 due to absorption or attenuation of radio waves due to the influence of moisture in the human body.

  Further, by applying the identification band 10 to the ankle band wound around the ankle, depending on the material of the floor surface of the passage 101 of the entrance / exit 100 where the R / W antenna 60 is installed, the radiation is radiated from the R / W antenna 60. It is also possible to increase the communication distance by reflecting radio waves on the floor surface.

<Use state and effect of identification band 10>
FIG. 6 is a schematic diagram illustrating a state in which the identification band 10 illustrated in FIG. 5 is wound around a wearing portion 70 of a wearer who is a manager. In particular, FIG. FIG. 6B shows a state in which the RF tag 2 is disposed on both side portions 70 a and 70 b of the attachment site 70, and FIG. 6B shows one RF tag 2 on one side of the attachment site 70. A state where the half-circumferential portion 70a is in the axially-facing posture is illustrated.

  In addition, in FIG. 6, illustration of the latching protrusion 3c of the base member 3, the contact member 5, and the fixing member 6 is omitted for convenience.

  Here, in FIG. 6, R / W antennas 60 (not shown) are respectively arranged on both sides of the ankle (attached portion 70) in the lateral width direction (x-axis direction) (both left and right sides in the drawing of FIG. 6). The W antenna 60 (the surface 60a thereof) is also in a state orthogonal to the lateral width direction (x-axis direction) of the ankle. That is, the R / W antenna 60 (the surface 60a thereof) is parallel to the front-rear direction (y-axis direction) of the ankle (attachment site 70).

  As shown in FIG. 6, the identification band 10 is at the other end of the base member 3 with respect to two adjacent engagement holes 7 a among the 15 engagement holes 7 a on the other end side of the mounting band 7. The two tip holes 3d are connected to each other by the engagement tool 8 to form an annular body.

  Specifically, the identification band 10 shown in FIG. 5 is circularly rolled as shown in FIG. 6, and the other end side of the mounting band 7 (the portion where the 15 engagement holes 7 a are formed) is the band of the base member 3. The base member 3 is overlapped with the two engaging holes 7a adjacent to each other among the 15 engaging holes 7a of the mounting band 7 so as to overlap with the distal ends of the extension portions 3b (the portions where the two distal end holes 3d are formed). The two tip holes 3d are aligned with each other, and the two tip holes 3d and the engagement holes 7a, which are superimposed on each other, are fastened together by the engagement tool 8 so that the other end side of the mounting band 7 is attached. The tip of the band extension 3b of the base member 3 is connected.

  The relationship between the two RF tags 2 and the R / W antenna 60 will be described with reference to FIG.

  Here, a state (posture) in which the projected area obtained by orthogonally projecting the antenna element 2b of the RF tag 2 onto the R / W antenna 60 matches the plane area of the antenna element 2b, that is, the antenna element 2b (of the RF tag 2) The state in which the surface 2b3 (see FIG. 3) is completely opposed to the R / W antenna 60 (the surface 60a thereof (see FIG. 1)) is referred to as “surface facing”. Further, a state in which the virtual center axis Mc of the antenna element 2b of the RF tag 2 is orthogonal to the R / W antenna 60 (the surface 60a thereof) is referred to as “axis facing”.

  When the RF tag 2 faces the R / W antenna 60 face-to-face, the virtual center axis Mc of the antenna element 2b of the RF tag 2 is orthogonal to the surface 60a of the R / W antenna 60. Therefore, the concept of “axis facing” includes the above-mentioned “face facing”.

  As shown in FIG. 6A, according to the identification band 10, it is used by being wound around a wearing part 70 of a wearer such as a manager, but in a wound state around the wearing part 70. The antenna element 2b of one RF tag 2 is in the state of being disposed on the one-side-side half-circumferential portion 70a of the attachment site 70, and the antenna element 2b of the other RF tag 2 is the other side of the attachment site 70. Two RF tags 2 are disposed on the base member 3 so as to be disposed on the part-side half-circumferential portion 70b.

  Moreover, according to the identification band 10, the antenna element 2b of one RF tag 2 is in a state where it is wound around the attachment site 70, and the one-side-side half-circumferential portion 70a of the attachment site 70 (FIG. 6). (A) right side) is arranged from the front side (upper side of FIG. 6 (a)) and is arranged over a range of more than half of the one side portion side circumferential portion 70a. Moreover, in this state, the antenna element 2b of the other RF tag 2 is the same as the other RF tag 2 in the other side half-circumferential portion 70b (left side in FIG. 6 (b)) of the attachment site 70. It arrange | positions from the front side (FIG. 6 (a) upper side), and is arrange | positioned over the range more than half of the said other side part side periphery part 70b.

  Here, the state in which the RF tag 2 can maximize the read / write distance with the R / W antenna 60 means that the antenna element 2b (the surface 2b3) of the RF tag 2 is connected to the R / W antenna 60 (the surface 60a). On the other hand, it is in a state of facing the face. This is because in the case of face-to-face alignment, the projection length Lb of the antenna element 2b of the RF tag 2 matches (matches) the wavelength of the radio wave radiated from the R / W antenna 60.

  In FIG. 6, the projection length Lb of the antenna element 2b of the RF tag 2 with respect to the R / W antenna 60 is illustrated. Since the projection length Lb of the antenna element 2b is generally considered to be proportional to the projection area of the antenna element 2b, in FIG. 6, the projection length Lb of the RF tag 2 is used as an index indicating the projection area of the antenna element 2b. ing.

  However, when the antenna element 2b of the RF tag 2 is compatible with the UHF band, even if the antenna element 2b is not in a face-to-face orientation with respect to the R / W antenna 60, that is, the antenna element 2b is curved and deformed (axially facing). Or the projection area of the antenna element 2b on the R / W antenna 60 exists even if it is inclined at an angle (except 90 °) with respect to the R / W antenna 60. In the case of the “opposite” orientation, the projected area of the antenna element 2b is smaller than the face-to-face orientation and the read / write distance and accuracy are reduced, but the read / write distance according to the size of the projected area. And accuracy can be obtained.

  On the other hand, even if it is the RF tag 2 corresponding to the UHF band that the change in the direction (angle) of the antenna element 2b with respect to the R / W antenna 60 has little influence on the read / write distance and accuracy, the antenna element 2b is the R / W antenna. When the posture is orthogonal to 60, communication with the R / W antenna 60 becomes impossible. That is, the UHF band RF tag 2 has a projected area of the antenna element 2b of “0” when the antenna element 2b is orthogonal to the R / W antenna 60 (also simply referred to as “orthogonal attitude”). It becomes impossible to read and write.

  For this reason, in the conventional wristband using the RF tag 2, when the manager walks while wearing the wristband 70, for example, on the wrist, the worn site 70 moves. If the wristband rotates around the attachment site 70 and the antenna element 2b of the RF tag 2 becomes orthogonal to the R / W antenna 60 of the RF reader / writer, the RF tag 2 becomes unreadable. was there.

  On the other hand, according to the identification band 10 of the present embodiment, the antenna element 2b of one of the RF tags 2 is one of the attachment portions 70 when it is attached to the ankle as shown in FIG. Since the antenna element 2b of the other RF tag 2 is disposed on the other side half-circumferential portion 70b of the other RF tag 2 as shown in FIG. In the case of the entrance / exit management system in which the R / W antennas 60 are respectively arranged on both sides of the portion 70 in the lateral direction, a sufficient read / write distance and read / write accuracy can be secured for both of the two RF tags 2.

  For example, the two RF tags 2 shown in FIG. 6A are not in the axial orientation, but the antenna element 2b is different from the axial orientation shown in FIG. 6B. The projected area is about 95%, and the radio wave from the R / W antenna 60 can be received about 95%. Therefore, even the two RF tags 2 shown in FIG. 6A can sufficiently maintain the read / write distance and accuracy necessary for detecting the entry / exit of the managed person.

  As shown in FIG. 6B, for example, one RF tag 2 has an antenna element 2b (surface 2b3) in an axially-facing posture with respect to one R / W antenna 60 (surface 60a). Thus, the other RF tag 2 has its antenna element 2b (surface 2b3) not facing the axial orientation with respect to the other R / W antenna 60 (surface 60a), and the other R / W antenna. 60 is a facing posture with a small projection area.

  In FIG. 6B, the virtual center axis Mc of the RF tag disposed on the one-side-side half-circumferential portion 70a of the attachment site 70 coincides with the x-axis.

  As described above, the identification band 10 of the present embodiment is arranged in parallel so that the antenna elements 2b of the two RF tags 2 are extended in the circumferential direction of the attachment site 70 (the direction that coincides with the rotation direction of the identification band 10). Even when the antenna element 2b of one RF tag 2 is placed in an orthogonal posture or an opposed posture close to the R / W antenna 60, the read / write distance may be reduced. Since the antenna element 2b of the RF tag 2 is in an axially-facing posture or an opposed posture close to the R / W antenna 60, it is possible to prevent a decrease in reading / writing distance and accuracy of the RF tag 2 as the entire identification band 10. Yes.

  Further, as described above, in the entrance / exit management system used in this embodiment, the R / W antennas 60 are arranged on both sides of the passage 101 of the facility entrance 100 with the antenna surfaces facing each other (see FIG. 1). .) When the person to be managed wears the identification band 10 and passes through the passage 101 of the facility entrance 100, the RF that is axially opposed to the R / W antenna 60 by one of the two R / W antennas 60. Tag 2 is detected with high accuracy.

  In addition, since two R / W antennas 60 are installed on both sides of the passage 101 of the facility entrance 100 with the two R / W antennas 60 facing each other, the RF tag 2 in the axially-facing posture shown in FIG. The RF tag 2 can be reliably detected by either one of the two R / W antennas 60 even if the arrangement position is switched between the inside and the outside of the attachment site 70 (ankle).

  In addition, in the RF tag 2, the total length La of the antenna element 2b corresponding to the UHF band is less than the length of the side half-circumferential portions 70a and 70b of the ankles (generally corresponding to about ½ circumference of the ankle). Yes. For this reason, when the antenna element 2b of the RF tag 2 is axially opposed to the R / W antenna 60, the antenna element 2b wraps around the other half-circumference part on the opposite side beyond the range of the half-circumference part of the ankle. It is prevented that the projection area of 2b decreases and the communication distance decreases.

  In addition, the ankle which is the attachment site 70 has a relatively flat surface portion of the one side half-circumferential portion 70a and the other side half-circumferential portion 70b on both sides in the lateral direction, and therefore the antenna element 2b of the RF tag 2 Can be suppressed to a minimum, and a decrease in read / write distance and read / write accuracy can be suppressed accordingly.

  Further, since the identification band 10 is an antenna element 2b corresponding to the UHF band and the reduction rate of the reading distance depending on the direction of the antenna element 2b is small, the circumferential direction of the identification band 10 and the antenna of the RF tag 2 Even when the antenna element 2b of the RF tag 2 is extended along the circumferential direction of the attachment site 70 so that the extending direction (longitudinal direction) of the element 2b coincides, the read / write accuracy of each RF tag 2 is sufficiently high. It can be secured.

  For this reason, even if the RF tag 2 rotates and moves around the attachment site 70 and the position thereof shifts, one of the two RF tags 2 has two antenna elements 2b. Since there is a high possibility that the posture of the W antenna 60 is close to an axially-facing posture, the read / write accuracy of the RF tag 2 provided in the identification band 10 as a whole is improved.

  In addition, since the extending direction (longitudinal direction) of the antenna element 2b coincides with the circumferential direction of the identification band 10, the antenna element 2b of the RF tag 2 is extended along the circumferential direction of the attachment site 70. Therefore, even if the RF tag 2 has a large overall length La like the antenna element 2b corresponding to the UHF band, the identification band 10 can be manufactured using this without changing the form of the ready-made mounting band 7. There are also benefits.

It is cut halfway from the top to the top.

  By forming the plurality of slits 21 a in the elastic buffer member 21 in this manner, the deformation resistance (internal stress) generated when the elastic buffer member 21 is curved and deformed along the outer periphery of the attachment site 70 is reduced, and the elastic buffer member 21 is elastic. It becomes easy to curve and deform the buffer member 21.

  As shown in FIG. 8, the elastic cushioning member 31 of the identification part 30 of the third embodiment has a water drainage structure in which the elastic structure has entered the air enclosing part. This elastic structure is formed by bending and deforming a flexible elastic sheet material in a meandering shape when viewed from the side, and is welded to the lower surface of the base member 3 to maintain a bellows-like form. It is integrated with the base member 3.

  In this elastic structure, a plurality of small arc curved surface portions 31 a are arranged in the longitudinal direction of the base member 3 on the upper portion thereof, and a plurality of large arc curved surface portions 31 b are arranged in the longitudinal direction of the base member 3 on the lower portion thereof. Are lined up. The large arc curved surface portion 31b has a smaller curvature when viewed from the side than the small arc curved surface portion 31a. As described above, the elastic structure is a continuous arch-shaped elastic body 31 c in which a plurality of arch-shaped large arc curved surface portions 31 b are continuously formed in the longitudinal direction of the base member 3 at the contact portion with the mounted portion 70.

  Further, in this continuous arch-shaped elastic body 31 c, a through space 31 d provided in the inner peripheral portion of the large arc curved surface portion 31 b is an air inclusion portion, and the entire side surface of the through space 31 d is in the width direction of the base member 3. The water that has been immersed in the through space 31d is drained.

  For example, as shown in FIG. 8, the continuous arch-shaped elastic body 31c is formed by bending a soft resin sheet material having a thickness of 1 mm in a meandering shape in a side view so that a plurality of large-arc curved surface portions 31b having the same shape are continuously repeated. In a state of being bent, each small arc curved surface portion 31a on the upper side of each large arc curved surface portion 31b is fixed to the lower surface of the base member 3 by welding.
