  Hereinafter, embodiments will be described with reference to the drawings.

  FIG. 1 illustrates one embodiment of a wearable device. FIG. 1 is an example in which the wearable device 10 is worn by the person P1 wearing the work clothes Wr.

  The wearable device 10 includes a conductor 111 having a predetermined length that can be bent, antennas 112 and 113, gloves GL, and a pocket Pk provided in the work clothes Wr. The antenna 112 is an example of a first induction unit that is connected to one end T1 of the conductor 111 and performs induction of radio waves at the one end T1. The antenna 113 is an example of a second induction unit that is connected to the other end T2 of the conductor 111 and performs induction of radio waves at the other end T2. In the following description, an element including the conductor 111, the antenna 112, and the antenna 113 is referred to as the extended antenna 11.

  The glove GL is an example of an attachment that attaches the antenna 112 to the hand of the person P1, for example. FIG. 1 shows an example in which an antenna 112 is worn on the right hand of a person P1 by a glove GL. The hand of the person P1 wearing the antenna 112 is an example of a body part that can access the communication unit C1 for short-range wireless communication mounted on the device EQ installed in the environment outside the person P1.

  Note that the part to which the antenna 112 is attached is not limited to the right hand to which the gloves GL shown in FIG. 1 are attached, but may be the left hand of the person P1, the left or right lower arm, or the like. The communication unit C1 mounted on the device EQ is an example of a first communication unit that is disposed outside the person P1 and has a function of performing short-range wireless communication. The communication unit C1 may be, for example, an electronic tag for near field communication or RFID, or a reading unit for reading information from an electronic tag for near field communication or RFID.

  The pocket Pk has a capacity capable of storing the mobile terminal UE such as a smartphone, and includes a holder 131 that fixes the antenna 113 so as to face the communication unit C2 for short-range wireless communication included in the mobile terminal UE. . The communication unit C2 included in the mobile terminal UE is an example of a second communication unit that has a function of performing short-range wireless communication and is carried by a person P1. The communication unit C2 may be a reading unit for reading information of an electronic tag for short-range wireless communication, or may be an electronic tag for short-range wireless communication or RFID. In addition, if the portable terminal UE has a size that can be stored in the pocket Pk of the work clothes Wr or the like, a reading for reading a tablet-type terminal device having a reading unit for short-range wireless communication or an RFID electronic tag It may be a device.

  The antenna 112 includes, for example, branch portions CL1a and CL1b branched into two. The two branch portions CL1a and CL1b are arranged so that the distance between them can be changed. For example, a ring-shaped coil is provided at the tip of each branch portion CL1a and CL1b.

  For example, the branch part CL1a is provided along the thumb part of the glove GL, and the coil of the branch part CL1a is fitted on the thumb of the hand to which the glove GL is attached, and is located around the thumb joint. For example, the branch part CL1b is provided along the index finger portion of the glove GL, and the coil of the branch part CL1b is fitted into the index finger of the hand on which the glove GL is worn, and around the second joint from the tip of the index finger. Located in. As shown in FIG. 1, the two branches CL1a and CL1b are attached to the person P1 in a direction in which the magnetic field generated by the coil of the branch CL1a and the magnetic field generated by the coil of the branch CL1b are in the same direction D1. It is desirable that The antenna 112 having the branch portions CL1a and CL1b that generate the magnetic field in the direction D1 has the electromagnetic characteristics of the branch portions CL1a and CL1b when the distance between the coils of the branch portions CL1a and CL1b exceeds a predetermined threshold Dt. A radio wave is induced with the first characteristic. In addition, the antenna 112 shown in FIG. 1 has a second characteristic in which the effects of the branches CL1a and CL1b are added when the distance between the coils of the two branches CL1a and CL1b is equal to or less than a predetermined threshold Dt. Induction of radio waves with characteristics.

  The threshold value Dt indicating the limit distance at which the action of the coils of the branch parts CL1a and CL1b is added is, for example, the branch parts CL1a and CL1b when the person P1 consciously brings the thumb and index finger opposite each other and approaches each other. It is set to the same value as the distance between. When the person P1 is performing an unconscious movement, the thumb joint is often placed near the base of the index finger. For this reason, when the person P1 is performing an unconscious movement, the distance between the coil of the branch part CL1a fitted to the thumb and the coil of the branch part CL1b fitted to the second joint from the tip of the index finger is , The threshold value Dt is rarely below.

  Here, the strength of the action of inducing radio waves by each of the branch parts CL1a and CL1b is such that, when the actions of the two branch parts CL1a and CL1b are added together, reading of the electronic tag located at a distance L1 is possible. Adjusted to possible strength. For example, a single characteristic value indicating the strength of the action of inducing radio waves by each of the branches CL1a and CL1b is a characteristic value indicating the strength of the action that enables reading of an electronic tag located at a distance L1. Is set to a smaller value. The cooperative characteristic value indicating the strength of the action when the actions of the two branches CL1a and CL1b are added is the strength of the action that enables reading of the electronic tag located at a distance L1. Is set to a value larger than the characteristic value indicating. It should be noted that the distance L1 is the distance between the part that is the work target and the hand of the person P1 that is brought close to the work when the person P1 performs work for checking each of the parts included in the apparatus EQ one by one. Set based on distance.

  That is, the antenna 112 shown in FIG. 1 has a first characteristic indicated by individual characteristic values and a cooperative characteristic value by changing the distance between the two branch parts CL1a and CL1b by the operation of the person P1. In either one of the second characteristics indicated by (1), a radio wave is induced at one end T1.

  For example, when the person P1 consciously performs an operation of making the thumb and forefinger face each other and the distance between the branch portions CL1a and CL1b is equal to or less than the threshold value Dt, the antenna 112 is indicated by the cooperative characteristic value. It functions as an antenna having the second characteristic. On the other hand, when the operation of making the thumb and forefinger's fingertips face each other is not performed, the distance between the branches CL1a and CL1b is equal to or greater than the threshold value Dt, and thus the antenna 112 has a first characteristic indicated by an individual characteristic value. Functions as an antenna.

  The operation of shortening the distance between the branches CL1a and CL1b by consciously making the thumb and index finger face each other causes the antenna 112 to show the second characteristic by deforming the part of the person P1 to which the antenna 112 is attached. This is an example of the operation. In the following description, an operation performed by the person P1 to cause the antenna 112 to exhibit the second characteristic by deforming the part of the person P1 to which the antenna 112 is attached may be referred to as a conscious operation. . The conscious operation is not limited to the operation in which the thumb and the index finger are opposed to each other, but may be an operation that is unlikely to be performed unconsciously by the person P1.

  In addition, the combination of the fingers wearing the branch portions CL1a and CL1b is not limited to the combination of the thumb and the index finger, and the possibility of approaching to a distance equal to or less than the threshold value Dt while the unconscious operation is performed by the person P1 is low. Other combinations may be used as long as they are combinations of fingers. For example, the branch portions CL1a and CL1b may be provided on the thumb portion and middle finger portion, thumb portion and ring finger portion, or thumb portion and little finger portion of the gloves GL. The shape of the antenna 112 is not limited to the ring shape shown in FIG. 1, and may include a mechanism that can switch the characteristics used for the induction of radio waves by a conscious operation by the person P 1. Wristband type may be used.

  Also, one end T1 of the conductor 111 shown in FIG. 1 is connected to the antenna 112 at the cuff of the work clothes Wr, for example, and the other end T2 of the conductor 111 is the antenna inside the pocket Pk that houses the mobile terminal UE. 113 is connected. The conductor 111 is sewn on, for example, the front or back surface of the cloth of the work clothes Wr, and the person P1 wearing the work clothes Wr performs an operation such as extending an arm, thereby causing one end T1 of the conductor 111 to be formed. And the antenna 112 can be moved freely. Then, the person P1 can bring the antenna 112 closer to a place within the distance L1 from the communication unit C1 included in the device EQ by moving the one end T1 of the conductor 111 and the antenna 112 by extending the arm.

  When a conscious operation is performed on the antenna 112 by the person P1 in a state where the distance between the antenna 112 and the communication unit C1 is equal to or less than the distance L1, the characteristic of the antenna 112 changes to the second characteristic. At this time, the induction path is supplied to the antenna included in the communication unit C1 by the magnetic field generated by the branch portions CL1a and CL1b included in the antenna 112, whereby the wireless path between the antenna 112 and the communication unit C1. 14 is connected. On the other hand, even when the distance between the antenna 112 and the communication unit C1 is equal to or less than the distance L1, if a conscious operation is not performed on the antenna 112 by the person P1, the communication between the communication unit C1 and the antenna 112 is not performed. The wireless path 14 is not connected. This is because the magnetic field generated by each of the branch portions CL1a and CL1b included in the antenna 112 is strong enough to supply induction power to the antenna included in the communication unit C1 when no conscious operation is performed. It is because it does not have.

  That is, according to the wearable device 10 including the extended antenna 11 having the antenna 112, the wireless path 14 between the antenna 112 and the communication unit C1 is connected with the conscious operation of the person P1, and the communication unit C1, Communication between C2 can be enabled. For example, as shown in FIG. 1, when the communication unit C1 is an electronic tag and the communication unit C2 is included in the mobile terminal UE, the communication between the communication units C1 and C2 is the power from the communication unit C2. Realized by supply. Conversely, when the communication unit C1 is included in a reading device having a function of reading information from the electronic tag, and the communication unit C2 is an electronic tag including a commuter pass, communication between the communication units C1 and C2 is performed. This is realized by supplying power from the communication unit C1.

  The wireless path 14 included in the wearable device 10 illustrated in FIG. 1 is connected over a period in which the conscious operation of the person P1 continues, and is disconnected when the conscious operation is released. Therefore, the wearable device 10 shown in FIG. 1 causes communication between the communication unit C1 and the communication unit C2 at a timing intended by the person P1, and communicates with the communication unit C1 at a timing not intended by the person P1. Communication with the part C2 can be stopped.

  In other words, the wearable device 10 shown in FIG. 1 has a communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication, regardless of which of the communication units C1 and C2 is the transmission side. Can be connected at a timing intended by the user.

  FIG. 2 shows another embodiment of the antenna 112 included in the wearable device 10 shown in FIG. 2 that are the same as those shown in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted.

  2A-1 and 2A-2 show another example of mounting the two branch parts CL1a, CL1b included in the antenna 112 shown in FIG.

  Each of the coils of the branch portions CL1a and CL1b shown in FIGS. 2A-1 and 2A-2 is built in, for example, two rings. In the example of FIGS. 2A-1 and 2A-2, the rings incorporating the coils of the branches CL1a and CL1b are connected to the index finger and ring finger of the right hand hr of the person P1 shown in FIG. It is fitted. Each of the branch portions CL1a and CL1b is connected to one end T1 of a conductor 111 having a predetermined length via a wiring portion Cc and a connector Cn provided on a cuff of the work clothes Wr. The wiring portion Cc includes a conductive wire that connects the connector Cn and each of the branch portions CL1a and CL1b, and a conductive wire that connects the branch portions CL1a and CL1b to each other.

  FIG. 2A-1 shows a state where each finger of the right hand hr of the person P1 is naturally extended. In this case, the branch portions CL1a and CL1b included in the antenna 112 are at least separated from the distance indicated by the thickness of the middle finger. Therefore, by setting the threshold value Dt to the thickness of the middle finger, the antenna 112 can be connected to the branches CL1a and CL1b in the shape shown by the relative positions of the branches CL1a and CL1b shown in FIG. The 1st characteristic shown by an individual characteristic value is shown.

  FIG. 2A-2 shows a state in which the person P1 performs an operation of crossing the index finger of the right hand hr with the middle finger as a conscious operation. In this case, the branch portions CL1a and CL1b included in the antenna 112 are brought closer to the branch portions CL1a and CL1b than the state shown in FIG. The distance between them is below the threshold value Dt. Thus, in the state shown in FIG. 2A-2, the actions of the branches CL1a and CL1b are added together, so that the antenna 112 exhibits the second characteristic in the region φa indicated by the broken line.

  That is, the antenna 112 shown in FIGS. 2A-1 and 2A-2 moves, for example, an arm to bring the region φa where the actions of the branches CL1a and CL1b are added close to the electronic tag, This is useful in applications such as reading pinpoint information on an electronic tag.

  2B-1 and 2B-2 show other examples of the antenna 112 included in the wearable device 10 shown in FIG.

  The antenna 112 shown in FIGS. 2B-1 and 2B-2 is, for example, a conductor 111 having a predetermined length via a connector Cn provided at a connection portion between the work clothes Wr and the gloves GL. It is a loop-shaped antenna connected to one end T1. The antenna 112 is sewn along the contour of the hand, for example, inside the glove GL.

  FIG. 2B-1 shows the shape of the antenna 112 in a state where each finger of the right hand hr of the person P1 is naturally spread. In the case of the shape shown in FIG. 2B-1, the antenna 112 guides radio waves in a region φb indicated by a broken line by a magnetic field induced by a lead wire that surrounds the palm wrist side of the loop antenna. Indicates the function to perform.

  FIG. 2B-2 shows the shape of the antenna 112 when the person P1 performs an operation of closing each finger of the right hand hr as a conscious operation. The antenna 112 transformed into the shape shown in FIG. 2 (B-2) has the region shown in FIG. 2 (B-1) because the magnetic fields induced by the conductive wires of the closed fingers are mutually enhanced. A function of guiding radio waves in a region φb ′ wider than φb is shown.

  In the region φb ′ shown in FIG. 2B-2, the strength of the action of guiding the radio wave indicated by the antenna 112 is adjusted so that the electronic tag included in the region φb ′ can be read. In this case, when the antenna 112 shown in FIGS. 2B-1 and 2B-2 is deformed by a conscious operation by the person P1, for example, the area of the right hand hr of the person P1 is substantially equal. It can be used for reading an electronic tag or the like included in the area φb ′ having an area.

  That is, the antenna 112 shown in FIGS. 2 (B-1) and 2 (B-2) is used, for example, by inserting a hand into a narrow gap about the thickness of the hand and reading an electronic tag or the like installed somewhere in the gap. It is useful in such cases.

  Further, the strength of the action of the antenna 112 maintaining the shape shown in FIG. 2B-1 inducing the radio wave shown in the region φb is, for example, when the hand wearing the antenna 112 is held over the electronic tag Are adjusted to such an extent that power can be supplied by induction to the electronic tag included in the region φb. When such adjustment is performed, the antenna 112 illustrated in FIGS. 2B-1 and 2B-2 can switch a range in which the electronic tag can be read in accordance with a conscious operation. be able to.

  The antenna 112 may be sewn into the glove GL in a shape in which a part of the contour corresponding to a finger included in the hand is omitted. For example, the shape of the antenna 112 may be a shape in which the contour of the thumb portion is omitted, or may be a shape showing the contour of the fingertip portion in which the portion surrounding the palm is omitted.

  FIG. 3 shows another embodiment of the antenna 112 included in the wearable device 10 shown in FIG. 3 that are equivalent to the components shown in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.

  For example, the antenna 112 shown in FIG. 3 includes an antenna Af fixed to the wrist of the person P1, a conductive rod-shaped device Gj, and antennas Ar1 and Ar2 installed on the device Gj.

  The appliance Gj is connected to the body of the person P1 by being grasped by the person P1, and conversely, the connection to the person P1 is released when the person P1 releases the appliance Gj. The antenna Ar1 is installed adjacent to, for example, a grip Gr provided at one end of the instrument Gj in order to designate a position where the person P1 grasps the instrument Gj. Further, the position of the antenna Ar1 is set to a position where the distance from the antenna Af is equal to or less than the predetermined value L2 when the person P1 grasps the instrument Gj at the position of the grip Gr. In addition, the antenna Ar2 is installed at the other end Eg1 away from the place where the antenna Ar1 is installed in the instrument Gj, and induces radio waves using the second characteristic at the other end Eg1 of the instrument Gj.

  The strength of the effect of inducing radio waves by each of the antenna Af and the antenna Ar1 is adjusted to the strength at which the wireless path is connected between the antenna Af and the antenna Ar1 when the distance between the antenna Af and the antenna Ar1 becomes a predetermined value L2. It is desirable that Moreover, the instrument Gj may include a mechanism for expanding and contracting the length.

  The antenna 112 shown in FIG. 3 is separated from the extension antenna 11 extended to the wrist of the person P1 by the conductor 111 sewed into the work clothes Wr by the length Lg of the appliance Gj by attaching the appliance Gj. The tool Gj can be further extended to the other end Eg1.

  Therefore, in the wearable device 10 having the antenna 112 shown in FIG. 3, even when the communication unit C1 is installed at a high place such as a ceiling, the other end Eg1 of the appliance Gj is placed at a position within the distance L1 from the communication unit C1. The wireless path 14 can be connected by approaching.

  For example, when the communication unit C1 is an electronic tag included in a sprinkler, a fire alarm, or the like, the wireless path 14 between the electronic tag and the antenna Ar2 uses the antenna Ar2 installed at the other end Eg1 of the appliance Gj as a sprinkler. Or connected to the fire alarm. Accordingly, the communication unit C2 inside the mobile terminal UE can read the information of the electronic tag. Further, information obtained by reading the electronic tag is stored in a memory or the like inside the mobile terminal UE as information indicating a history of the sprinkler or fire alarm, or information indicating the state of the sprinkler or fire alarm, for example. May be.

  That is, the wearable device 10 having the antenna 112 shown in FIG. 3 is useful in the field of inspection of equipment that is often installed on the ceiling of a building or a wall surface near the ceiling.

The reading unit C4 has a function of performing short-range wireless communication, and is an example of a second communication unit carried by the person P1, and corresponds to the communication unit C2 illustrated in FIG.

  The device EQ shown in FIG. 4 includes a switch SW that is an example of components included in the device EQ, and an electronic tag Tag0 associated with the switch SW. The electronic tag Tag0 is an example of a first communication unit that is mounted on a device EQ outside the person and has a function of performing short-range wireless communication, and corresponds to the communication unit C1 illustrated in FIG. Further, the electronic tag Tag0 holds tag information associated with the switch SW in a built-in memory.

  The wireless path 14 between the antenna 112 and the electronic tag Tag0 shown in FIG. 4 is consciously deformed into a shape corresponding to the second characteristic, for example, as described with reference to FIGS. Connected when the operation is performed by the person P1.

  In the example of FIG. 4, the communication path including the wireless path 14 connected between the antenna 112 and the electronic tag Tag0, the conductor 111, and the wireless path between the antenna 113 and the communication unit C2 is read. Used for reading the electronic tag Tag0 by the part C4. That is, the wearable device 10 shown in FIG. 4 has a function of extending the range that can be read by the reading unit C4 carried by the person P1 at the timing when the person P1 performs a conscious operation on the antenna 112.

Further, the control unit 15 may generate text and image information indicating an inspection procedure for the switch SW and the like from the acquired information.

  The presentation unit 16 illustrated in FIG. 4 is, for example, a glasses-type head mounted display (HMD) or the like, and displays an image or the like indicating information received from the control unit 15 on the display unit, thereby displaying the person P1. To present.

  FIG. 5 shows the operation of the wearable device 10 shown in FIG. The processing of step S301 to step S303 shown in FIG. 5 shows the operation of the wearable device 10 shown in FIG. 4, and also shows an example of an interface control method and an interface control program using the wearable device 10 shown in FIG. . For example, the processing illustrated in FIG. 5 is realized by a processor mounted on the mobile terminal UE connected to the wearable device 10 executing an interface control program. Note that the processing illustrated in FIG. 5 may be executed by hardware mounted on the wearable device 10. That is, FIG. 5 shows an embodiment of an interface control method and an interface control program.

  In step S301, for example, the control unit 15 illustrated in FIG. 4 determines whether the wireless path between the antenna 112 and the electronic tag Tag0 is connected based on the state of the communication unit C2.

  When the identification information included in the second tag Tg2 is received from the short-range wireless communication interface 23 before the predetermined time τ1 elapses after reading the first tag Tg1 (Yes in step S323 (YES)) Then, the processor 21 proceeds to the process of step S324.

  In step S324, the processor 21 determines whether or not the elapsed time from the reading of the second tag Tg2 exceeds a predetermined time τ2. The predetermined time τ2 is, for example, the third tag Tg3 and the antenna Af shown in FIG. 9 when the user pulls out the appliance Gj from the fixing portion Hld shown in FIG. 6 and then holds the grip Gr of the appliance Gj. It is desirable that the time is set to about the time until the two are opposed to each other.

  When the elapsed time from the reading of the second tag Tg2 is less than the predetermined time τ2 (No determination in step S324 (NO)), the processor 21 proceeds to the process of step S325.

  In step S325, the processor 21 determines whether or not the third tag Tg3 has been read based on whether or not the identification information included in the third tag Tg3 is transmitted from the antenna Af to the short-range wireless communication interface 23. judge.

  When the third tag Tg3 has not been read yet (No determination in step S325 (NO)), the processor returns to the process of step S324, and repeats the processes of step S324 and step S325, whereby the third tag Wait for reading of Tg3.

  When the identification information included in the third tag Tg3 is received from the short-range wireless communication interface 23 before the predetermined time τ2 has elapsed since the second tag Tg2 was read (Yes in step S325 (YES)) ), The processor 21 proceeds to the process of step S326.

  In step S326, together with the current time, the processor 21 generates history information indicating that the appliance Gj is attached to the user in a usable state, and stores the generated history information in the memory 22 illustrated in FIG. To do.

  In step S327, the processor 21 outputs information indicating that the appliance Gj is correctly attached, and then the processor 21 ends the process of inspecting the attachment state of the appliance Gj, and in step S312 shown in FIG. Proceed to processing.

  On the other hand, when the elapsed time after the first tag Tg1 is read before the second tag Tg2 is read is equal to or longer than the predetermined time τ1 (Yes in step S322 (YES)), the processor 21 The process proceeds to step S328. Similarly, when the elapsed time after reading the second tag Tg2 before the third tag Tg3 is equal to or longer than the predetermined time τ2 (Yes determination in step S324 (YES)), the processor 21 The process proceeds to step S328.

  In step S328, the processor 21 outputs information indicating that the appliance Gj is not correctly attached, and then the processor 21 ends the process of inspecting the attachment state of the appliance Gj, and step S312 shown in FIG. Proceed to the process.

  Note that the processor 21 may store, in the memory 22, information indicating the time when the abnormality of the wearing state of the appliance Gj is detected in the course of the process of step S <b> 328 as a part of the history information.

  By executing the processing from step S321 to step S328 shown in FIG. 11, the processor 21 collects information related to the wearing state of the appliance Gj, and accumulates history information generated based on the collected information in the memory 22. Can do. That is, it is one of the embodiments of the determination unit that determines the wearing state of the appliance Gj that the processor 21 executes the processes of steps S321 to S328.

  FIG. 12 shows an example of processing for inspecting the storage state of the appliance Gj shown in step S314 in FIG. Each process of step S331 to step S336 illustrated in FIG. 12 is an example of a process included in an application program for an interface control process using the wearable device 10. Further, the processes in steps S331 to S336 are executed by the processor 21 shown in FIG.

  In step S331, the processor 21 determines whether or not the identification information included in the second tag Tg2 is transmitted from the reading unit 17 to the short-range wireless communication interface 23 illustrated in FIG. It is determined whether or not has been read.

  When the second tag Tg2 has not been read yet (No determination in step S331 (NO)), the processor returns to the process of step S331 and repeats the process of step S331, thereby reading the second tag Tg2. Await.

  On the other hand, when the identification information included in the second tag Tg2 is received from the short-range wireless communication interface 23 (Yes determination in step S331), the processor 21 proceeds to the process of step S332.

  In step S332, the processor 21 determines whether or not the elapsed time after the second tag Tg2 is read is equal to or longer than the predetermined time τ3. The predetermined time τ3 elapses from when the second tag Tg2 is read until the first tag Tg1 is read when the user stores the appliance Gj in the fixing portion Hld shown in FIG. 6, for example. It is desirable that the time is set to the expected time.

  When the elapsed time from the reading of the second tag Tg2 is less than the predetermined time τ3 (No determination in step S332 (NO)), the processor 21 proceeds to the process of step S333.

  In step S333, whether or not the processor 21 has read the first tag Tg1 based on whether or not the identification information included in the first tag Tg1 is transmitted from the reading unit 17 to the short-range wireless communication interface 23. Determine.

  When the first tag Tg1 has not been read yet (No determination in step S333 (NO)), the processor returns to the process of step S332, and repeats the processes of step S332 and step S333, whereby the first tag Wait for reading of Tg1.

  When the identification information included in the first tag Tg1 is received from the short-range wireless communication interface 23 before the predetermined time τ3 has elapsed since the second tag Tg2 was read (Yes in step S333 (YES)) ), The processor 21 proceeds to the process of step S334.

  In step S334, along with the current time, the processor 21 generates history information indicating that the appliance Gj is stored in the fixed portion Hld, and stores the generated history information in the memory 22 illustrated in FIG.

  In step S335, the processor 21 outputs information indicating that the appliance Gj has been correctly stored, and then the processor 21 ends the process of inspecting the storage state of the appliance Gj, and in step S315 shown in FIG. Proceed to processing.

  On the other hand, when the elapsed time since the second tag Tg2 is read before the first tag Tg1 is read is equal to or longer than the predetermined time τ3 (Yes determination in step S332 (YES)), the processor 21 proceeds to step S336. Proceed to the process.

  In step S336, the processor 21 outputs information indicating that the instrument Gj is not stored correctly, and then the processor 21 ends the process of inspecting the storage state of the instrument Gj, and step S315 shown in FIG. Proceed to the process.

These are all useful information for managing the appliance Gj.

  That is, the processor 21 shown in FIG. 9 executes the processing of each step shown in FIGS. 10 to 12, so that the wearable device 10 provides an easy-to-use interface for the user and manages the appliance Gj. Useful information can be accumulated.

  FIG. 13 shows another embodiment of a wearable device. Note that among the constituent elements shown in FIG. 13, those equivalent to the constituent elements shown in FIG. 1 and FIG. 3 are given the same reference numerals, and description thereof is omitted. The wireless connection in FIG. 13 shows a state where the antenna Aw13 and the antenna Ac1 are connected wirelessly. 13 indicates that the communication path between the antenna Aw13 and the antenna Ac1 is blocked. In the unconnected state of FIG. 13, the description of the periphery of the antenna Aw12, the person P1, and the like are omitted to make the drawing easier to see. The antenna Ac1 is an example of the antenna of the communication partner of the antenna Aw10. The antenna Ac1 is, for example, the antenna of the communication unit C1 shown in FIG.

  The wearable device 10A of this embodiment has an antenna Aw10. The antenna Aw10 is an example of a third guide unit that is at least partially attached to a part where a human body can voluntarily move. The antenna Aw10 corresponds to, for example, the antenna 112 shown in FIG. For example, the antenna Aw10 includes an antenna Aw11 fixed to the wrist or the like of the person P1, a conductive rod-shaped device Gj, and antennas Aw12 and Aw13 installed on the device Gj. The antennas Aw11, Aw12, and Aw13 may have the same sensitivity or different sensitivities.

  The antenna Aw11 is an example of a first antenna that functions as an antenna and is attached to a part where a human body can voluntarily move. For example, one end T1 of the conductor 111 is connected to the antenna Aw11. The other end of the conductor 111 is connected to an antenna 113 arranged to face the communication unit C2 for short-range wireless communication, for example, as described with reference to FIG. The other end of the conductor 111 may be connected to the communication unit C2 illustrated in FIG.

  The instrument Gj is an example of an instrument that can be held by a person and has a predetermined length. For example, the appliance Gj is connected to the body of the person P1 by being grasped by the person P1, and conversely, the connection to the person P1 is released when the person P1 releases the appliance Gj.

  The antenna Aw12 is an example of a second antenna that is installed at a location where the distance from the first antenna is equal to or less than the second distance when a person holds the instrument. The antenna Aw12 is installed adjacent to, for example, a grip Gr provided at one end of the instrument Gj in order to designate a position where the person P1 grasps the instrument Gj. For example, the antenna Aw12 is installed at a position where the distance from the antenna Aw11 is equal to or less than the predetermined value L2 when the person P1 grasps the instrument Gj at the position of the grip Gr.

  For example, the strength of the action of inducing radio waves by each of the antennas Aw11 and Aw12 is adjusted to the strength at which the wireless path is connected between the antennas Aw11 and Aw12 when the distance between the antennas Aw11 and Aw12 is equal to or less than a predetermined value L2. Has been. Therefore, for example, when the person P1 grasps the appliance Gj at the position of the grip Gr, the distance between the antenna Aw11 and the antenna Aw12 becomes equal to or less than the predetermined value L2, and the antenna Aw11 and the antenna Aw12 are connected wirelessly.

  In other words, when the person P1 releases the appliance Gj, the distance between the antenna Aw11 and the antenna Aw12 is greater than the predetermined value L2, and the communication path between the antenna Aw11 and the antenna Aw12 is blocked. That is, when the distance between the antenna Aw11 and the antenna Aw12 is longer than the distance L2, the communication path between the antenna Aw11 and the antenna Aw12 is blocked. In addition, when the distance between the antenna Aw11 and the antenna Aw12 is equal to or less than the distance L2, the antenna Aw11 and the antenna Aw12 are wirelessly connected.

  Note that the state in which the distance between the antenna Aw11 and the antenna Aw12 is greater than the distance L2 is an example of the first state. The state where the distance between the antenna Aw11 and the antenna Aw12 is equal to or less than the distance L2 is an example of the second state. That is, the antenna Aw10 is selected from the first state and the second state in accordance with the change in the shape of the antenna Aw10 (change in the distance between the antenna Aw11 and the antenna Aw12).

  The antenna Aw13 is an example of a third antenna connected to the second antenna through a conductor. In the example of FIG. 13, a bar-shaped instrument Gj having conductivity functions as a conductor. For example, the antenna Aw13 is installed in the instrument Gj at a position away from the place where the antenna Aw12 is installed and at a position away from the end Eg1 from the distance L1. The distance from the antenna Aw13 to the end Eg1 is, for example, a distance L10 that is longer than the distance L1.

  For example, the strength of the action of guiding the radio waves by the antennas Aw13 and Ac1 is such that the wireless path 14 is connected between the antennas Aw13 and Ac1 when the distance between the antennas Aw13 and Ac1 is equal to or less than a predetermined value L1. It has been adjusted. Therefore, for example, when the distance between the antenna Aw13 and the antenna Ac1 is equal to or less than the predetermined value L1, the antenna Aw13 and the antenna Ac1 are wirelessly connected. In other words, when the distance between the antenna Aw13 and the antenna Ac1 is greater than the predetermined value L1, the communication path between the antenna Aw13 and the antenna Ac1 is blocked.

  For example, the communication path between the antenna Aw10 and the antenna Ac1 is a wireless path between the antenna Aw11 and the antenna Aw12, a portion (conductor) between the antennas Aw12 and Aw13 of the appliance Gj, and between the antenna Aw13 and the antenna Ac1. Wireless path 14. Therefore, in the first state in which the distance between the antenna Aw11 and the antenna Aw12 is greater than the distance L2, the communication path between the antenna Aw11 and the antenna Aw12 is blocked, so the communication path between the antenna Aw10 and the antenna Ac1 is Blocked.

  The antenna Aw10 is in a second state where the distance between the antenna Aw11 and the antenna Aw12 is a distance L2 or less, and when the distance from the communication partner antenna Ac1 is a distance L1 or less, the communication path with the communication partner antenna Ac1. Establish. Thereby, a communication path between the antenna Aw10 and the antenna Ac1 is established. For example, a communication unit (for example, the communication unit C2 in FIG. 1) connected to the antenna Aw10 via the conductor 111 or the like is communicably connected to a communication unit (for example, the communication unit C1 in FIG. 1) including the antenna Ac1. The

  Here, in the example of FIG. 13, the shape of the communication partner antenna Ac1 is hollow. In the instrument Gj, the male part Gjm, which is the end Eg1 on the side where the antenna Aw13 is installed, has a shape that can be inserted into the female part Ac1f that is a hollow part of the antenna Ac1 of the communication partner. For example, in the second state, when the male part Gjm is inserted into the female part Ac1f until the distance between the antenna Aw13 and the communication partner antenna Ac1 is equal to or less than the distance L1, the antenna Aw13 and the communication partner antenna Ac1 are wirelessly connected. Connected (wireless connection in FIG. 13). As a result, a communication path between the antenna Aw10 and the communication partner antenna Ac1 is established.

  In the second state, the communication path between the antenna Aw13 and the antenna Ac1 is cut off by separating the communication partner antenna Ac1 from the antenna Aw13 from the distance L1, so the antenna Aw10 and the communication partner antenna Ac1 are disconnected. The communication path is blocked (not connected in FIG. 13). In the first state, since the communication path between the antenna Aw11 and the antenna Aw12 is blocked, the communication path between the antenna Aw10 and the antenna Ac1 of the communication partner is independent of the distance between the antenna Aw13 and the antenna Ac1. Not established.

  For example, when it is difficult for the antenna Aw10 to bring the antenna Aw11 extended to the wrist of the person P1 by the conductor 111 sewn into the work clothes Wr up to a distance communicable with the antenna Ac1, the device Gj is attached. Thus, the antenna Aw11 and the antenna Ac1 can be connected to be communicable.

  For example, the antenna Aw10 can be further extended to a position separated by a length Lg10 by attaching an instrument Gj to the antenna extended to the wrist of the person P1 by the conductor 111 sewn into the work clothes Wr. . Accordingly, the wearable device 10A having the antenna Aw10 is configured such that, for example, even when the antenna Ac1 is installed at a high place such as a ceiling, the antenna Aw13 of the appliance Gj is brought closer to a location within the distance L1 from the antenna Ac1. Can be established.

  For example, when the antenna Ac1 is an antenna of an electronic tag included in a sprinkler or a fire alarm, the wireless path 14 between the electronic tag and the antenna Aw13 brings the antenna Aw13 of the appliance Gj closer to the sprinkler or fire alarm. Connected with. Accordingly, the communication unit connected to the antenna Aw11 via the conductor 111 or the like can read information on the electronic tag. Thus, the wearable device 10A having the antenna Aw10 is useful in the field of inspection of equipment that is often installed on the ceiling of a building or a wall surface near the ceiling.

  Further, for example, in the antenna Aw10, the antenna Aw13 can be opposed to the antenna Ac1 by inserting the male part Gjm of the antenna Aw10 into the female part Ac1f of the antenna Ac1. Therefore, for example, even when it is difficult to visually confirm the positional relationship between the antennas Aw13 and Ac1, the person P1 determines whether or not the male part Gjm is inserted into the female part Ac1f. It can be determined whether or not it faces Ac1.

  For example, at a position where the antenna Aw10 does not face the antenna Ac1, the male part Gjm of the antenna Aw10 is not inserted into the female part Ac1f of the antenna Ac1. For this reason, the antenna Aw10 can suppress the antenna Aw13 from approaching a location within the distance L1 from the antenna Ac1 at a timing not intended by the person P1. In other words, the antenna Aw13 is brought closer to a location within the distance L1 from the antenna Ac1 at the timing intended by the person P1. That is, the wearable device 10A illustrated in FIG. 13 can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication at a timing intended by the user. .

  As described above, the communication path between the antenna Aw10 and the antenna Ac1 is connected over a period in which the conscious operation of the person P1 continues, and is disconnected when the conscious operation is released. That is, the wearable device 10A illustrated in FIG. 13 can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication at a timing intended by the user. .

  Note that the configuration of the wearable device 10A is not limited to this example. For example, the instrument Gj may include a mechanism for expanding and contracting the length. For example, the male part Gjm and the female part Ac1f may be omitted.

  As described above, the wearable device 10A according to the embodiment illustrated in FIG. 13 includes the antenna Aw10 that is selected from the first state and the second state in accordance with the change in the shape of the portion that functions as the antenna. . For example, when the antenna Aw10 is in the first state, the communication path with the communication partner antenna Ac1 is blocked. And when it is a 2nd state and the distance with antenna Ac1 is below distance L1, the communication path | route of antenna Aw10 and antenna Ac1 is established.

  For example, when the instrument Gj is grasped by the person P1, the antenna Aw10 enters the second state. Conversely, when the person P1 releases the appliance Gj, the antenna Aw10 enters the first state. Thereby, in this embodiment, the communication path | route between the communication part used as the transmission side of near field communication and the communication part used as the receiving side can be connected with the timing which the user intended.

  FIG. 14 shows another embodiment of a wearable device. 14 that are the same as those shown in FIGS. 1 to 13 are given the same reference numerals, and descriptions thereof are omitted. FIG. 14 shows a first state in which the distance between the antenna Aw21 and the antenna Aw22 is greater than the distance L2, and a second state in which the distance between the antenna Aw21 and the antenna Aw22 is equal to or less than the distance L2. The antenna Ac2 is an example of the antenna of the communication partner of the antenna Aw20. The antenna Ac2 is, for example, the antenna of the communication unit C1 illustrated in FIG.

  The wearable device 10A of this embodiment has an antenna Aw20. The antenna Aw20 is an example of a third guide unit that is at least partially attached to a site where a human body can voluntarily move. The antenna Aw20 corresponds to, for example, the antenna Aw10 illustrated in FIG. For example, the antenna Aw20 includes a ring-shaped antenna Aw21 attached to a person's finger or the like, and an expansion member MA1.

  The antenna Aw21 is attached to a part (for example, a finger) where a human body can voluntarily move. For example, the distance from the antenna Aw21 fitted to the finger to the fingertip is about a distance L20 longer than the distance L2. For example, as described with reference to FIG. 1 and the like, the antenna Aw21 is connected to the communication unit C2 for short-range wireless communication via the conductor 111, the wireless path, and the like. The antenna Aw21 may be connected to the communication unit C2 through only a wired path (conductor 111).

  The expansion member MA1 includes a ring-shaped antenna Aw22, an antenna Aw23 connected to the antenna Aw22 via a conductor 111A, and a recess MA1c. For example, the antenna Aw22 is disposed near the surface of the expansion member MA1 (a surface on which a person's finger can contact). And the recessed part MA1c is arrange | positioned at the hollow part of antenna Aw22. In addition, the antenna Aw22 is connected to the antenna Aw23 arranged to face the antenna Ac2 via the conductor 111A, for example. The antennas Aw21, Aw22, and Aw23 may have the same sensitivity or different sensitivities.

  For example, the antenna Ac2 is arranged in a part MA2 of the communication unit. For example, when the part MA2 of the communication unit and the expansion member MA1 overlap, the distance between the antenna Aw23 and the antenna Ac2 is equal to or less than the predetermined value L1. For example, the antenna Aw23 is wirelessly connected to the antenna Ac2 when the distance between the antenna Aw23 and the antenna Ac2 is equal to or less than the distance L1.

  Even if a finger fitted with the ring-shaped antenna Aw21 contacts the surface of the expansion member MA1, the distance between the antenna Aw21 and the antenna Aw22 is about a distance L20 longer than the distance L2 in a state where the fingertip is not inserted into the recess MA1c. It is. For example, the antenna Aw21 is wirelessly connected to the antenna Aw22 when the distance between the antenna Aw21 and the antenna Aw22 is equal to or less than the distance L2. That is, when the distance between the antenna Aw21 and the antenna Aw22 is about the distance L20, the communication path between the antenna Aw21 and the antenna Aw22 is blocked.

  Therefore, even when a finger wearing the ring-shaped antenna Aw21 contacts the surface of the expansion member MA1, the communication path between the antenna Aw21 and the antenna Aw22 is blocked when the fingertip is not inserted into the recess MA1c. . Thus, in the first state in which the distance between the antenna Aw21 and the antenna Aw22 is greater than the distance L2, the communication path between the antenna Aw21 and the antenna Aw22 is blocked, so the antenna Aw20 and the antenna Ac2 of the communication partner are not connected. The communication path is blocked.

  On the other hand, in a state where the fingertip is inserted into the recess MA1c, the antenna Aw21 approaches the antenna Aw22 by the depth of the recess MA1c. For example, when the depth of the recess MA1c is about the distance L20, the antenna Aw21 can be brought closer to the location within the distance L2 from the antenna Aw22 by inserting the fingertip into the recess MA1c. Thereby, the antenna Aw21 and the antenna Aw22 are wirelessly connected.

  That is, the state where the finger with the antenna Aw21 is inserted into the recess MA1c corresponds to the second state in which the distance between the antenna Aw21 and the antenna Aw22 is equal to or less than the distance L2. Thus, the antenna Aw20 is selected from the first state and the second state in accordance with the change in the shape of the antenna Aw20 (change in the distance between the antenna Aw21 and the antenna Aw22).

  In the second state, since the antenna Aw21 and the antenna Aw22 are wirelessly connected, when the distance between the antenna Aw23 and the antenna Ac2 is equal to or less than the distance L1, the communication path between the antenna Aw20 and the antenna Ac2 of the communication partner is Established.

  As described above, the communication path between the antenna Aw20 and the antenna Ac2 is connected over a period in which the conscious operation of the person continues, and is disconnected when the conscious operation is released. That is, the wearable device 10A illustrated in FIG. 14 can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication at a timing intended by the user. .

  Further, for example, in the antenna Aw20, it is determined whether or not the antenna Aw21 is opposed to the antenna Aw22 by determining whether or not the fingertip is inserted into the recess MA1c without visually confirming the position of the antenna Aw22. I can judge. For example, when the antenna Ac2 is an antenna of an electronic tag and the antenna Aw21 fitted to the finger is connected to the reading device via the conductor 111 or the like, the user accesses the electronic tag almost simultaneously with reading the tag information. You can confirm with your fingertips.

  Note that the configuration of the wearable device 10A is not limited to this example. For example, the expansion member MA1 including the recess MA1c may be included in the communication unit of the communication partner. In this case, the communication partner antenna Ac2 may be formed in a ring shape, and the ring antenna Ac2 may be arranged at the position of the antenna Aw22 shown in FIG. 14 instead of the antenna Aw22.

  As described above, the wearable device 10A according to the embodiment illustrated in FIG. 14 includes the antenna Aw20 that is selected from the first state and the second state in accordance with the change in the shape of the portion that functions as the antenna. . For example, when the antenna Aw20 is in the first state, the communication path with the communication partner antenna Ac2 is blocked. When the antenna Aw20 is in the second state and the distance between the antenna Aw23 and the antenna Ac2 is equal to or less than the distance L1, the communication path between the antenna Aw20 and the antenna Ac2 is established.

  For example, when a finger with the antenna Aw21 is inserted into the recess MA1c, the antenna Aw20 enters the second state. On the contrary, the antenna Aw20 is in the first state when the finger wearing the antenna Aw21 is separated from the recess MA1c. Thereby, in this embodiment, the communication path | route between the communication part used as the transmission side of near field communication and the communication part used as the receiving side can be connected with the timing which the user intended.

  FIG. 15 shows another embodiment of a wearable device. 15 that are the same as those shown in FIGS. 1 to 14 are given the same reference numerals, and descriptions thereof are omitted. FIG. 15 shows a first state in which the finger wearing the antenna Aw31 extends and a second state in which the finger wearing the antenna Aw31 is bent.

  The antenna Ac3 is an example of the antenna of the communication partner of the antenna Aw30. The antenna Ac3 is, for example, the antenna of the communication unit C1 illustrated in FIG. For example, the antenna Ac3 is disposed in the vicinity of the surface (a surface on which a person's finger can contact) of a part MA3 of the communication unit. The shape of the antenna Ac3 is hollow. For example, the concave portion MA3c is disposed in the hollow portion of the antenna Ac3.

  The wearable device 10A of this embodiment has an antenna Aw30. The antenna Aw30 is an example of a third guide unit that is at least partially attached to a part where a human body can voluntarily move. The antenna Aw30 corresponds to, for example, the antenna Aw10 illustrated in FIG. For example, the antenna Aw30 includes a conductive mounting portion RN and a ring-shaped antenna Aw31 mounted on a person's finger or the like via the mounting portion RN. For example, the antenna Aw31 is wirelessly connected to the antenna Ac3 when a predetermined ratio (for example, almost the whole) of the antenna Aw31 is located at a position within the distance L1 from the antenna Ac3. In the following description, it is assumed that the antenna Aw31 and the antenna Ac3 are connected wirelessly when the entire antenna Aw31 is located at a location within the distance L1 from the antenna Ac3.

  The mounting portion RN is an example of a mounting portion that holds the state of the third guide portion in either the first state or the second state. For example, as shown in FIG. 15, the mounting portion RN is mounted on a finger of a person's hand, and an antenna Aw31 is disposed at the end on the fingertip side. The antenna Aw31 attached to the mounting part RN is connected to the communication part C2 for short-range wireless communication shown in FIG. 1 via the conductive mounting part RN, the conductor 111, the wireless path, and the like, for example. The antenna Aw31 may be connected to the communication unit C2 only through a wired path (the mounting unit RN and the conductor 111).

  The state in which the finger wearing the mounting portion RN is extended corresponds to the first state in which the communication path between the antenna Aw31 and the antenna Ac3 is blocked. For example, when the finger wearing the mounting portion RN is extended, the mounting portion RN holds the antenna Aw31 so as to be inclined with respect to the direction in which the finger extends. For this reason, in the first state where the finger fitted with the mounting portion RN is extended, the antenna Aw31 is inclined with respect to the antenna Ac3 even if the finger is brought close to the antenna Ac3. It is difficult to position almost the entire antenna Aw31.

  For example, as shown in the first state of FIG. 15, even if the finger is brought close to the antenna Ac3, the fingertip does not enter the deep position of the recess MA3c. It is difficult to position. Further, even if the fingertip is inserted to a position deep in the recess MA3c with the finger extended, the antenna Aw31 is inclined with respect to the antenna Ac3. It is difficult to make it. Therefore, in the first state in which the finger wearing the mounting portion RN is extended, the communication path between the antenna Aw31 and the antenna Ac3 is blocked. For this reason, the communication path between the antenna Aw30 and the antenna Ac3 is blocked.

  On the other hand, in a state where the finger wearing the mounting portion RN is bent, it is possible to position almost the entire antenna Aw31 at a location within the distance L1 from the antenna Ac3. For example, the mounting unit RN holds the antenna Aw31 so as to be substantially parallel to the plane when the fingertip is attached to the plane with the finger wearing the mounting unit RN bent. Therefore, in a state where the finger fitted with the mounting portion RN is bent, as shown in the second state of FIG. 15, the antenna Aw31 is made substantially parallel to the antenna Ac3 and the fingertip is inserted to a deep position of the recess MA3c. it can.

  Therefore, in a state where the finger fitted with the mounting portion RN is bent, almost the entire antenna Aw31 can be positioned at a location within the distance L1 from the antenna Ac3 by inserting the fingertip into the recess MA3c. When almost the entire antenna Aw31 is located at a position within the distance L1 from the antenna Ac3, the antenna Aw31 is wirelessly connected to the antenna Ac3, and a communication path between the antenna Aw30 and the antenna Ac3 is established. That is, the state where the finger wearing the mounting portion RN is bent corresponds to the second state.

  As described above, the mounting unit RN holds the state of the antenna Aw30 in the first state when the finger is extended, and holds the state of the antenna Aw30 in the second state when the finger is bent. Therefore, the communication path between the antenna Aw30 and the antenna Ac3 is connected over a period in which the conscious operation of the person continues, and is disconnected when the conscious operation is released. That is, the wearable device 10A illustrated in FIG. 15 can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of near field communication at a timing intended by the user. .

  Further, for example, in the antenna Aw30, it is determined whether or not the antenna Aw31 faces the antenna Ac3 by determining whether or not the fingertip is inserted into the recess MA3c without visually confirming the position of the antenna Ac3. I can judge. For example, when the antenna Ac3 is an antenna of an electronic tag and the antenna Aw31 is connected to the reading device via the conductor 111 or the like, the user accesses the electronic tag with the fingertip almost simultaneously with reading of the tag information. I can confirm.

  As described above, the wearable device 10A according to the embodiment shown in FIG. 15 has the first state and the second state according to the change in shape (bending and stretching of the finger) of the part (the finger of the person's hand) to which the antenna Aw30 is attached. The antenna Aw30 is selected as one of the above. For example, when the antenna Aw30 is in the first state, the communication path with the communication partner antenna Ac3 is blocked. When the antenna Aw30 is in the second state and the distance between the antenna Aw31 and the antenna Ac3 is equal to or less than the distance L1, the communication path between the antenna Aw30 and the antenna Ac3 is established.

  For example, the antenna Aw30 is in the second state by bending a finger fitted with the mounting portion RN. On the contrary, the antenna Aw30 is in the first state by extending the finger fitted with the mounting portion RN. Thereby, in this embodiment, the communication path | route between the communication part used as the transmission side of near field communication and the communication part used as the receiving side can be connected with the timing which the user intended.

  Further, the antennas (for example, the antennas Aw31 and Ac3) may be opposed to each other and connected by communication by using the flexibility of the finger to squeeze the finger when touched.

  FIG. 16 shows another embodiment of a wearable device. Note that among the components shown in FIG. 16, components equivalent to those shown in FIGS. 1 to 15 are denoted by the same reference numerals, and description thereof is omitted. FIG. 16 shows a first state in which the finger wearing the antenna Aw40 extends and a second state in which the finger wearing the antenna Aw40 is bent.

  The antenna Ac4 is an example of the antenna of the communication partner of the antenna Aw40. The antenna Ac4 is, for example, the antenna of the communication unit C1 illustrated in FIG. For example, when viewed from the side, the antenna Ac4 has a shape in which the end is bent downward from the center. For example, the height when the antenna Ac4 is viewed from the side is larger than the predetermined value L1.

  For example, the antenna Aw40 is wirelessly connected to the antenna Ac3 when a predetermined ratio (for example, almost the whole) of the antenna Aw40 is located at a position within the distance L1 from the antenna Ac4. In the following description, it is assumed that the antenna Aw40 and the antenna Ac4 are connected wirelessly when the entire antenna Aw40 is located at a location within the distance L1 from the antenna Ac4.

  The wearable device 10A of this embodiment has an antenna Aw40. The antenna Aw40 is an example of a seventh antenna that can be deformed into a shape that matches the shape of the communication partner antenna. That is, the antenna Aw40 is an example of a third guide unit that is at least partially attached to a part where a human body can voluntarily move. The antenna Aw40 corresponds to, for example, the antenna Aw10 illustrated in FIG. For example, as described in FIG. 1 and the like, the antenna Aw40 is connected to the communication unit C2 for short-range wireless communication via the conductor 111, the wireless path, and the like. The antenna Aw40 may be connected to the communication unit C2 only through a wired path (conductor 111).

  The antenna Aw40 is attached to a finger, for example. For example, the antenna Aw40 has a shape corresponding to the contour of a finger. The shape of the antenna Aw40 can be deformed even after the antenna Aw40 is attached to the finger. For example, in a state where the finger wearing the antenna Aw40 is extended, the antenna Aw40 is maintained in a state in which the finger extends in the extending direction.

  The state in which the finger wearing the antenna Aw40 is extended corresponds to the first state in which the communication path between the antenna Aw40 and the antenna Ac4 is blocked. For example, in the state where the finger wearing the antenna Aw40 is extended, as shown in the first state of FIG. 16, even if the antenna Aw40 is brought close to the antenna Ac4, the vicinity of the center portion of the antenna Ac4 that is bent with the antenna Aw40. The distance to is greater than the distance L1. That is, in the state where the finger wearing the antenna Aw40 is extended, it is difficult to position the entire antenna Aw31 at a location within the distance L1 from the antenna Ac4. Therefore, in the first state where the finger wearing the antenna Aw40 is extended, the communication path between the antenna Aw40 and the antenna Ac4 is blocked.

  On the other hand, in a state where the finger wearing the antenna Aw40 is bent, it is possible to position almost the entire antenna Aw40 at a location within the distance L1 from the antenna Ac4. For example, in the state where the finger with the antenna Aw40 is bent, the antenna Aw40 bends along the bending of the finger. As a result, the antenna Aw40 is deformed into a shape that matches the shape of the antenna Ac4, as shown in the second state of FIG. Therefore, the antenna Aw40 faces the antenna Ac4 in an optimal state.

  For example, in a state in which the finger wearing the antenna Aw40 is bent, the antenna Aw40 can be positioned close to the antenna Ac4 so that almost the entire antenna Aw40 can be positioned within a distance L1 from the antenna Ac4. When almost the entire antenna Aw40 is located at a position within the distance L1 from the antenna Ac4, the antenna Aw40 is wirelessly connected to the antenna Ac4. That is, a communication path between the antenna Aw40 and the antenna Ac4 is established. Therefore, the state in which the finger wearing the antenna Aw40 is bent corresponds to the second state.

  As described above, the antenna Aw40 can be deformed into a shape that matches the shape of the antenna Ac4 of the communication partner by deforming the portion (finger in FIG. 16) to which the antenna Aw40 is attached. For example, the second state is selected by deforming the antenna Aw40 into a shape that matches the shape of the communication partner antenna Ac4.

  Accordingly, the communication path between the antenna Aw40 and the antenna Ac4 is connected over a period in which the conscious operation of the person continues, and is disconnected when the conscious operation is released. That is, the wearable device 10A illustrated in FIG. 16 can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication at a timing intended by the user. .

  Further, for example, in the antenna Aw40, it is possible to determine whether the antenna Aw40 is opposed to the antenna Ac4 or not by visually checking the position of the antenna Ac4 by the finger feeling of the portion where the antenna Aw40 is attached. For example, when the antenna Ac4 is an antenna of an electronic tag and the antenna Aw40 is connected to the reading device via the conductor 111 or the like, almost simultaneously with the reading of the tag information, the user indicates that the user has accessed the electronic tag. It can be confirmed by touch.

  Note that the configuration of the wearable device 10A is not limited to this example. For example, the antenna Aw40 may be sewn inside the glove along the outline of the finger.

  As described above, the wearable device 10A according to the embodiment shown in FIG. 16 has the first state and the second state according to the change in shape (bending and stretching of the finger) of the part (the finger of the person's hand) to which the antenna Aw40 is attached. The antenna Aw40 is selected as one of the above. For example, when the antenna Aw40 is in the first state, the communication path with the communication partner antenna Ac4 is blocked. When the antenna Aw40 is in the second state and the distance between the antenna Aw40 and the antenna Ac4 is equal to or less than the distance L1, the communication path between the antenna Aw40 and the antenna Ac4 is established.

  For example, by bending a finger equipped with the antenna Aw40, the antenna Aw40 is deformed into a shape that matches the shape of the antenna Ac4 of the communication partner and enters the second state. On the other hand, the antenna Aw40 is in the first state by extending the finger wearing the antenna Aw40. Thereby, in this embodiment, the communication path | route between the communication part used as the transmission side of near field communication and the communication part used as the receiving side can be connected with the timing which the user intended.

  FIG. 17 illustrates another embodiment of a wearable device. Note that, among the components shown in FIG. 17, components equivalent to those shown in FIGS. 1 to 16 are denoted by the same reference numerals and description thereof is omitted. A broken circle in the electronic tag Tag (Tag 10, Tag 11, Tag 12, Tag 13) in FIG. 17 indicates an antenna of the electronic tag Tag. The antenna of the electronic tag Tag is an example of the antenna of the communication partner of the antenna Aw50. The electronic tag Tag is, for example, the communication unit C1 illustrated in FIG. In this embodiment, the electronic tag Tag is attached to, for example, a part of a person's body away from the part where the antenna Aw52 is attached.

  The wearable device 10A of this embodiment has an antenna Aw50. The antenna Aw50 is an example of a third guide unit that is at least partially attached to a part where a human body can voluntarily move. The antenna Aw50 corresponds to, for example, the antenna Aw10 illustrated in FIG. For example, the antenna Aw50 includes an antenna Aw51 fixed to a person's wrist (the wrist of the left hand H1 in the example of FIG. 17), an expansion member MA4, antennas Aw52 and Aw53 installed on the expansion member MA4, and a conductor 111A. Including. The antennas Aw51, Aw52, and Aw53 may have the same sensitivity or different sensitivities.

  The antenna Aw51 is an example of a fourth antenna that is attached to a part where a human body can voluntarily move. The antenna Aw52 is an example of a fifth antenna that is wirelessly connected to the fourth antenna when the distance from the fourth antenna is equal to or smaller than the second distance. The antenna Aw53 is an example of a sixth antenna connected to the fifth antenna via a conductor having a predetermined length.

  The expansion member MA4 is an example of an external environment where the fifth antenna and the sixth antenna are installed. The expansion member MA4 is, for example, an object that a person contacts or an object that a person approaches. For example, the expansion member MA4 is an armrest of a car or a sofa. Hereinafter, the case where the expansion member MA4 is an armrest will be described as an example. Therefore, the expansion member MA4 is also referred to as an armrest MA4.

  For example, as described with reference to FIG. 1 and the like, the antenna Aw51 is connected to the communication unit C2 for short-range wireless communication via the conductor 111, the wireless path, and the like. Note that the antenna Aw51 may be connected to the communication unit C2 only through a wired path (conductor 111).

  The antenna Aw52 is installed near the upper surface of the armrest MA4, for example. The antenna Aw52 may be installed inside the armrest MA4 or may be installed on the outer surface of the armrest MA4. For example, the antenna Aw52 is installed at a position where the distance from the antenna Aw51 is equal to or less than the predetermined value L2 when the person places the left hand Hl on the armrest MA4.

  The antenna Aw52 is wirelessly connected to the antenna Aw51 when the distance from the antenna Aw51 is equal to or less than the distance L2. Therefore, for example, when a person places the left hand Hl on the armrest MA4, the distance between the antenna Aw51 and the antenna Aw52 is equal to or less than the distance L2, and the antenna Aw51 and the antenna Aw52 are wirelessly connected.

  In other words, when the person moves the left hand Hl away from the armrest MA4, the distance between the antenna Aw51 and the antenna Aw52 is greater than the distance L2, and the communication path between the antenna Aw51 and the antenna Aw52 is blocked. The state where the distance between the antenna Aw51 and the antenna Aw52 is greater than the distance L2 is an example of the first state. The state where the distance between the antenna Aw51 and the antenna Aw52 is equal to or less than the distance L2 is an example of the second state. That is, the antenna Aw50 is selected from the first state and the second state in accordance with the change in the shape of the antenna Aw50 (change in the distance between the antenna Aw51 and the antenna Aw52).

  The antenna Aw53 is installed, for example, in the vicinity of the front surface of the armrest MA4, and is connected to the antenna Aw52 via the conductor 111A. The antenna Aw53 and the conductor 111A may be installed inside the armrest MA4 or may be installed on the outer surface of the armrest MA4. The position of the antenna Aw53 is such that, for example, when a person puts the fingertip of the left hand Hl close to the antenna Aw53 with the left hand Hl placed on the armrest MA4, the distance from the fingertip of the left hand Hl to the antenna Aw53 becomes a predetermined value L1 or less. Set to position. Note that electronic tags Tag10, Tag11, Tag12, and Tag13 are attached to the fingertips of the left hand Hl except for the thumb.

  That is, for example, the antenna Aw53 is installed at a position where the distance from the antenna of the electronic tag Tag can be set to a predetermined value L1 or less when the person places the left hand Hl on the armrest MA4. The antenna Aw53 is wirelessly connected to the antenna of the electronic tag Tag when the distance from the antenna of the electronic tag Tag is equal to or less than the distance L1. In other words, for example, when the distance between the antenna Aw53 and the antenna of the electronic tag Tag is greater than the predetermined value L1, the communication path between the antenna Aw53 and the antenna of the electronic tag Tag is blocked.

  For example, the communication path between the antenna Aw50 and the antenna of the electronic tag Tag includes a wireless path between the antenna Aw51 and the antenna Aw52, a conductor 111A, and a wireless path between the antenna Aw53 and the antenna of the electronic tag Tag. It is out. Therefore, in the first state in which the distance between the antenna Aw51 and the antenna Aw52 is greater than the distance L2, the communication path between the antenna Aw51 and the antenna Aw52 is blocked, so that communication between the antenna Aw50 and the antenna of the electronic tag Tag is performed. The path is blocked.

  In the second state where the distance between the antenna Aw51 and the antenna Aw52 is equal to or less than the distance L2, the antenna Aw53 and the antenna of the electronic tag Tag are wireless when the distance between the antenna Aw53 and the antenna of the electronic tag Tag is equal to or less than the distance L1. Connected with. Thereby, a communication path between the antenna Aw50 and the antenna of the electronic tag Tag is established.

  For example, a communication unit (for example, the communication unit C2 in FIG. 1) connected to the antenna Aw50 via the conductor 111 or the like is communicably connected to the electronic tag Tag close to the antenna Aw53. Thereby, for example, the tag information of the electronic tag Tag brought close to the antenna Aw53 is read.

  In the second state, the communication path between the antenna Aw50 and the antenna of the electronic tag Tag is blocked by separating the antenna of the electronic tag Tag from the antenna Aw53 from the distance L1.

  For example, when a communication unit connected to the antenna Aw50 via the conductor 111 or the like is a reading device built in an audio device, and an audio operation is assigned to the electronic tag Tag, the audio device uses the electronic tag Tag. Can be operated. For example, playback, skip, stop, and return are assigned to the electronic tags Tag10, Tag11, Tag12, and Tag13. In this case, for example, when the user places the left hand H1 on the armrest MA4 and brings the index finger (electronic tag Tag10) of the left hand H1 close to the antenna Aw53, the tag information (reproduction command) of the electronic tag Tag10 can be read. Accordingly, the audio device connected to the antenna Aw50 via the conductor 111 or the like reproduces music.

  Here, for example, the sensitivity of each antenna of the antenna Aw51 and the RFID tag Tag is such that even if the tag attached to the fingertip of the left hand Hl is brought close to the antenna Aw51 attached to the left wrist, a wireless path is connected between them. It is desirable to adjust to a strength that is not possible. In this case, even if the person puts the left hand H1 away from the armrest MA4 and brings the tag attached to the fingertip of the left hand H1 closer to the antenna Aw51 attached to the left wrist, the distance that the wireless path is connected between the two It is difficult to approach (for example, distances L1 and L2). Thereby, in this embodiment, it can suppress that the communication path | route of antenna Aw50 and the antenna of an electronic tag Tag is established at the timing which a person does not intend.

  As described above, the communication path between the antenna Aw50 and the antenna of the electronic tag Tag is connected over a period in which the conscious operation of the person continues, and is disconnected when the conscious operation is released. That is, the wearable device 10A illustrated in FIG. 17 can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication at a timing intended by the user. .

  Note that the configuration of the wearable device 10A is not limited to this example. For example, the expansion member MA4 may include a recess as shown in FIG.

  As described above, the wearable device 10A according to the embodiment illustrated in FIG. 17 includes the antenna Aw50 that is selected from the first state and the second state in accordance with the change in the shape of the portion that functions as the antenna. . For example, when the antenna Aw50 is in the first state, the communication path with the antenna of the electronic tag Tag (communication partner) is blocked. When the antenna Aw50 is in the second state and the distance between the antenna Aw53 and the antenna of the electronic tag Tag is equal to or less than the distance L1, a communication path between the antenna Aw50 and the antenna of the electronic tag Tag is established.

  For example, the antenna Aw50 is in the second state by placing the left hand Hl on the armrest MA4. Conversely, the antenna Aw50 is in the first state by separating the left hand Hl from the armrest MA4. Thereby, in this embodiment, the communication path | route between the communication part used as the transmission side of near field communication and the communication part used as the receiving side can be connected with the timing which the user intended.

  FIG. 18 illustrates another embodiment of a wearable device. 18 that are the same as those shown in FIGS. 1 to 17 are denoted by the same reference numerals and description thereof is omitted. The wearable device 10A illustrated in FIG. 18 includes an expansion member MA5 including a recess MA5c instead of the expansion member MA4 illustrated in FIG. The other configuration of wearable device 10A is the same as that of wearable device 10A shown in FIG. The meanings of the dashed circles in the electronic tags Tag (Tag 10, Tag 11, Tag 12, and Tag 13) in FIG. 18 are the same as those in FIG.

  The wearable device 10A of this embodiment has an antenna Aw60. The antenna Aw60 is an example of a third guide unit that is at least partially attached to a part where a human body can voluntarily move. The antenna Aw60 is the same as the antenna Aw50 shown in FIG. 17 except that the extension member MA5 including the recess MA5c is provided instead of the extension member MA4 shown in FIG.

  For example, the antenna Aw60 includes an antenna Aw61 fixed to a person's wrist (the wrist of the left hand H1 in the example of FIG. 18), an expansion member MA5, antennas Aw62 and Aw63 installed on the expansion member MA5, and a conductor 111A. Including. The antennas Aw61, Aw62, and Aw63 are the same as the antennas Aw51, Aw52, and Aw53 shown in FIG. The shape of the antenna Aw63 is hollow. The antennas Aw61, Aw62, and Aw63 may have the same sensitivity or different sensitivities.

  The expansion member MA5 is an example of an external environment in which the fifth antenna and the sixth antenna are installed. The expansion member MA5 is the same as the expansion member MA4 except that a recess MA5c is added to the expansion member MA4 shown in FIG. For example, the expansion member MA5 is an armrest of a car or a sofa. Hereinafter, the case where the expansion member MA5 is an armrest will be described as an example. Therefore, the expansion member MA5 is also referred to as an armrest MA5.

  The recess MA5c is disposed, for example, in a hollow portion of the antenna Aw63. The depth of the recess MA5c is, for example, about the thickness of the finger to which the electronic tag Tag is attached. Further, the distance L1 at which wireless communication between the antenna Aw63 and the antenna of the electronic tag Tag is possible is smaller than the thickness of the finger, for example.

  In this case, for example, when the finger with the electronic tag Tag is in contact with the front surface of the armrest MA5 and the fingertip is not inserted into the recess MA5c, the distance between the antenna of the electronic tag Tag and the antenna Aw63 is the distance It is far from L1. Therefore, even if the finger with the electronic tag Tag attached contacts the front surface of the armrest MA5, the communication path between the antenna of the electronic tag Tag and the antenna Aw63 is blocked when the fingertip is not inserted into the recess MA5c. The That is, the communication path between the antenna Aw60 and the antenna of the electronic tag Tag is blocked.

  On the other hand, in the state where the fingertip is inserted into the recess MA5c, the antenna of the electronic tag Tag approaches the antenna Aw63 by the depth of the recess MA5c. For this reason, the antenna of the electronic tag Tag can be brought closer to a location within the distance L1 from the antenna Aw63. Thereby, the antenna of the electronic tag Tag and the antenna Aw63 are wirelessly connected. As a result, a communication path between the antenna Aw60 and the antenna of the electronic tag Tag is established.

  As described above, the wearable device 10A according to the embodiment shown in FIG. 18 can achieve the same effects as the wearable device 10A according to the embodiment shown in FIG. For example, in this embodiment, a communication path between a communication unit serving as a transmission side and a communication unit serving as a reception side can be connected at a timing intended by the user. Furthermore, in this embodiment, whether or not the antenna of the electronic tag Tag is opposed to the antenna Aw63 by determining whether or not the fingertip is inserted into the recess MA5c without visually confirming the position of the antenna Aw63. Can be determined.

  FIG. 19 shows another embodiment of a wearable device. FIG. 19 shows an example of a system including the wearable device 10B and an antenna of a communication partner of the wearable device 10B. An antenna including the antenna ANT20 and a plurality of induction antennas Ae20 connected to the antenna ANT20 via the conductor 111C is an example of an antenna of a communication partner of the wearable device 10B.

  Therefore, the communication unit capable of wireless communication with wearable device 10B includes antenna ANT20, induction antenna Ae20, and conductor 111C. The antenna ANT20, the induction antenna Ae20, and the conductor 111C are installed on the floor, for example. Further, the antenna ANT20 is disposed, for example, facing the antenna of the electronic tag or the antenna of the reading device. In FIG. 19, a plurality of induction antennas Ae20 (Ae20a, Ae20b, Ae20c, Ae20d) are illustrated using broken lines or thick lines for easy viewing. Further, the number of induction antennas Ae20 is not limited to four.

  Wearable device 10B of this embodiment is installed in slippers, shoes SH, etc., for example. Wearable device 10B may be installed in footwear other than shoes. Hereinafter, description will be made assuming that the wearable device 10B is installed in the shoe SH.

  The wearable device 10B includes an antenna ANT10 and a plurality of induction antennas Ae10 (Ae10a, Ae10b) connected to the antenna ANT10 via a conductor 111B. The number of induction antennas Ae10 is not limited to two. The plurality of induction antennas Ae10 are an example of a plurality of first induction antennas that function as antennas and have maximum resonance at a predetermined frequency.

  The plurality of induction antennas Ae10 are adjusted so that resonance is maximized at a predetermined frequency (for example, 13.56 MHz). The plurality of induction antennas Ae10 are arranged so as to partially overlap each other, and are combined as a single antenna so that resonance is maximized at a predetermined frequency (for example, 13.56 MHz). The whole of the plurality of induction antennas Ae10a and Ae10b combined as a single antenna is installed along the shape of the foot, for example, on the insole of the shoe SH or the shoe SH. In the example of FIG. 19, the two induction antennas Ae10 are arranged such that when they are combined as one antenna, the overlapping portions are located near the center of the whole.

  The antenna ANT10 is an example of an eighth antenna connected to a plurality of first induction antennas via conductors. The antenna ANT10 is disposed to face the antenna of the electronic tag and the antenna of the reading device. For example, when the antenna ANT20 of the communication partner is arranged to face the antenna of the reading device, the antenna ANT10 is arranged to face the antenna of the electronic tag. Alternatively, when the communication partner antenna ANT20 is disposed opposite to the antenna of the electronic tag, the antenna ANT10 is disposed opposite to the reading device antenna.

  On the other hand, for the floor-side antenna that is the communication partner of wearable device 10B, for example, a plurality of induction antennas Ae20 function as antennas and are adjusted so that resonance is maximized at a predetermined frequency (for example, 13.56 MHz). Has been. The plurality of induction antennas Ae20 are arranged so as to partially overlap each other, and are grouped as one antenna so that resonance is maximized at a predetermined frequency (for example, 13.56 MHz). In the example of FIG. 19, the four induction antennas Ae20 are arranged such that when they are combined as one antenna, the overlapping portions are located near the center of the whole.

  In other words, the floor-side antenna has a plurality of antennas that have the maximum resonance at a predetermined frequency and are arranged so that some of them overlap each other as a single antenna, and the entire antenna has the maximum resonance at a predetermined frequency. It is an example of the antenna of the communicating party adjusted so that it may become.

  Each antenna size (for example, length in the longitudinal direction) of the induction antenna Ae20 is smaller than, for example, the overall antenna size (for example, length in the longitudinal direction) in which the plurality of induction antennas Ae10 are combined as one antenna. That is, the floor-side antenna is divided so that the minimum unit antenna size (the antenna size of the induction antenna Ae20) is smaller than the antenna size of the entire antenna installed in the shoe SH.

  In other words, the overall antenna size obtained by combining the plurality of induction antennas Ae10 as one antenna is larger than the minimum unit antenna size of the communication partner antenna (the antenna size of the induction antenna Ae20). Further, the overall antenna size in which the plurality of induction antennas Ae10 are combined as one antenna is smaller than the antenna size of the entire communication partner (the entire combination of the plurality of induction antennas Ae20 as one antenna), for example.

  Thereby, the wearable device 10B can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication at a timing intended by the user. For example, when the antenna ANT10 is disposed opposite to the antenna of the reader, the tag information on the floor is obtained when the user brings the shoe SH close to the portion where the induction antenna Ae20 is installed (for example, stepping on the floor). Is read.

  Here, for example, in a system in which the induction antennas Ae10 and Ae20 are omitted, the antenna ANT10 faces the antenna ANT20 even though the user intends to make the antenna ANT10 installed on the shoe SH face the antenna ANT20 installed on the floor. May not have.

  For example, in a system in which the induction antennas Ae10 and Ae20 are omitted, the antenna ANT10 may be approximately the same size as the antenna ANT20, and a portion obtained by removing the size of the antenna ANT10 from the size of the shoe SH may be larger than the size of the antenna ANT10. In this case, even if the user steps on the floor of the part where the antenna ANT20 is installed with the shoe SH, the part of the shoe SH excluding the antenna ANT10 faces the antenna ANT20, and the antenna ANT10 is not close to the antenna ANT20. is there.

  Further, for example, when the user brings the antenna ANT10 installed in the shoe SH close to the antenna ANT20 installed on the floor, the antenna ANT10 and ANT20 are hidden in the shoe, so that the user has a positional relationship between the antennas ANT10 and ANT20. Cannot be confirmed visually.

  Thus, even if the user intends to bring the antenna ANT10 closer to the antenna ANT20, the antenna ANT10 may not be located in a range where wireless communication with the antenna ANT20 is possible. In this case, the communication path between the communication unit serving as the transmission side of the short-range wireless communication and the communication unit serving as the reception side is not connected at the timing intended by the user.

  On the other hand, in the wearable device 10B, the overall antenna size in which the plurality of induction antennas Ae10 are combined as one antenna is the entire antenna of the communication partner (the entire combination of the plurality of induction antennas Ae20 as one antenna). Smaller than size. Further, the overall antenna size in which the plurality of induction antennas Ae10 are combined as one antenna is larger than the minimum antenna size of the communication partner antenna (the antenna size of the induction antenna Ae20).

  For this reason, for example, when the user steps on the floor where the antenna Ae20 is installed with the shoe SH, at least one of the plurality of induction antennas Ae10 can wirelessly communicate with at least one of the plurality of induction antennas Ae20. Located in range. Therefore, the wearable device 10B can connect the communication path between the communication unit serving as the transmission side and the communication unit serving as the reception side of the short-range wireless communication at a timing intended by the user. The configuration of wearable device 10B is not limited to this example.

  FIG. 20 shows an example of a method for adjusting the induction antenna Ae10 installed in the shoe SH. First, the two induction antennas Ae10 (Ae10a, Ae10b) are individually adjusted so that resonance is maximized at a predetermined frequency (for example, 13.56 MHz) (individual adjustment in FIG. 20). Then, the two induction antennas Ae10 adjusted so as to maximize the resonance at a predetermined frequency are collected as one antenna. For example, the two induction antennas Ae10 are arranged such that when they are combined as one antenna, the overlapping portions are located near the center of the whole.

  In addition, an antenna ANT10 facing the antenna of the electronic tag or the antenna of the reader is installed at one end of the conductor 111B connected to the two induction antennas Ae10. After the antenna ANT10 and the two induction antennas Ae10 are installed, adjustment is made so that the entire antenna obtained by combining the two induction antennas Ae10 as one antenna has the maximum resonance at a predetermined frequency (for example, 13.56 MHz). (Overall adjustment in FIG. 20).

  FIG. 21 shows an example of a method for adjusting the induction antenna Ae20 installed on the floor. First, the four induction antennas Ae20 (Ae20a, Ae20b, Ae20c, Ae20d) are individually adjusted so that resonance is maximized at a predetermined frequency (for example, 13.56 MHz) (individual adjustment in FIG. 21). Then, the four induction antennas Ae20 adjusted so as to maximize the resonance at a predetermined frequency are collected as one antenna. For example, the four induction antennas Ae20 are arranged such that portions that overlap each other when positioned as one antenna are located near the center of the whole.

  In addition, an antenna ANT20 facing the antenna of the electronic tag or the antenna of the reading device is installed at one end of the conductor 111C connected to the four induction antennas Ae20. After the antenna ANT20 and the four induction antennas Ae20 are installed, adjustment is performed so that the resonance of the entire antenna obtained by combining the four induction antennas Ae20 as one antenna becomes maximum at a predetermined frequency (for example, 13.56 MHz). (Overall adjustment in FIG. 21). Note that the predetermined frequency described with reference to FIGS. 19 to 21 is not limited to 13.56 MHz.

  As described above, the wearable device 10B of the embodiment shown in FIG. 19 to FIG. 21 functions as an antenna and is connected to a plurality of induction antennas Ae10 having a maximum resonance at a predetermined frequency via a conductor. Antenna ANT10. The plurality of induction antennas Ae10 are arranged so as to partially overlap each other, and are grouped as one antenna so that resonance is maximized at a predetermined frequency. For example, the overall antenna size in which the plurality of induction antennas Ae10 are combined as one antenna is larger than the minimum unit antenna size of the communication partner antenna and smaller than the communication partner overall antenna size.

  Thereby, in this embodiment, the communication path | route between the communication part used as the transmission side of near field communication and the communication part used as the receiving side can be connected with the timing which the user intended.
