[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0011] <First embodiment> [Wearable device configuration] Fig. 1 is a diagram showing a wearable device 100. Referring to Fig. 1, the wearable device 100 includes a base 130, a first arm 111, and a second arm 112. The first arm 111 and the second arm 112 extend from both ends of the base 130. Each of the first arm 111 and the second arm 112 has a shape that curves and extends to fit along the head of the subject A when the wearable device 100 is worn.

[0012] The tips of the first arm 111 and the second arm 112 extend to form a roughly semicircle. The arc of this roughly semicircle is hung on the ears of subject A. The tip of the first arm 111 is formed with a left ear hook 121 that is hung on the left ear of subject A. The tip of the second arm 112 is formed with a right ear hook 122 that is hung on the right ear of subject A.

[0013] Wearable device 100 further includes a first wiring 141, a second wiring 142, a third wiring 143, a fourth wiring 144, a fifth wiring 145, and a sixth wiring 146. Wearable device 100 also includes a first sensor 101, a second sensor 102, a third sensor 103, a fourth sensor 104, a fifth sensor 105, and a sixth sensor 106 that are connected to first wiring 141 to sixth wiring 146, respectively.

[0014] The first sensor 101 is built into the first electrode pad 151. The second sensor 102 is built into the second electrode pad 152. The third sensor 103 is built into the third electrode pad 153. The fourth sensor 104 is built into the fourth electrode pad 154. The fifth sensor 105 is built into the fifth electrode pad 155. The sixth sensor 106 is built into the sixth electrode pad 156.

[0015] When the wearable device 100 is worn, the first sensor 101, the second sensor 102, the third sensor 103, the fourth sensor 104, the fifth sensor 105, and the sixth sensor 106 are attached to the subject's head via the first electrode pad 151, the second electrode pad 152, the third electrode pad 153, the fourth electrode pad 154, the fifth electrode pad 155, and the sixth electrode pad 156, respectively.

[0016] A first wiring 141, a second wiring 142, and a third wiring 143 are arranged along the first arm 111. As described later, the first wiring 141, the second wiring 142, and the third wiring 143 are arranged in a groove formed in the first arm 111. The first sensor 101 is connected to one end 141A of the first wiring 141. The second sensor 102 is connected to one end 142A of the second wiring 142. The third sensor 103 is connected to one end 143A of the third wiring 143.

[0017] A fourth wiring 144, a fifth wiring 145, and a sixth wiring 146 are arranged along the second arm 112. As described later, the fourth wiring 144, the fifth wiring 145, and the sixth wiring 146 are arranged in a groove formed in the second arm 112. The fourth sensor 104 is connected to one end 144A of the fourth wiring 144. The fifth sensor 105 is connected to one end 145A of the fifth wiring 145. The sixth sensor 106 is connected to one end 146A of the sixth wiring 146. The grooves are formed on the surfaces of the first arm 111 and the second arm 112 that face each other.

[0018] Hereinafter, the first sensor 101 to the sixth sensor 106 are collectively referred to as a "sensor group." The sensor group is attached to the head of the subject A when the wearable device 100 is worn, and detects physical data of the subject A. The physical data is data related to the body of the subject A, and includes, for example, at least one of the following: myoelectric potential of the subject's face, the subject's sweat rate, the subject's body temperature, the amount of water in the subject's body, the subject's pulse wave, the subject's sound, the acceleration of the subject's body part (the subject's mouth or jaw), brain waves, brain activity, and cardiac potential. The subject's sound includes, for example, sounds inside the subject's body (for example, breathing sounds or swallowing sounds, etc.). The acceleration of the subject's body part includes, for example, the acceleration of the subject's muscles, etc.

[0019] 2 and 3 are diagrams showing a state in which the wearable device 100 of the first embodiment is worn on the head and neck of a subject A, and a sensor of the wearable device 100 is attached to the subject A. The head and neck of a subject is typically the part above the neck of the subject. FIG. 2 is a diagram showing the subject A as viewed diagonally from behind, and FIG. 3 is a diagram showing the subject A as viewed from the front. A detection system, which will be described later, estimates the emotion of the subject A wearing the wearable device 100. In addition to the subject A, there is an analyst (not shown) who checks the estimation result of the emotion of the subject A. Hereinafter, the analyst and the subject A will be collectively referred to as the "user".

[0020] 2 shows a base 130, a first arm 111, a second arm 112, a first sensor 101, a second sensor 102, and a third sensor 103. The first arm 111 is the left arm in the mounted state, and the second arm 112 is the right arm in the mounted state. Note that the first arm 111 may be the right arm in the mounted state, and the second arm 112 may be the left arm in the mounted state.

[0021] 2 shows a state in which the left ear hook 121 of the first arm 111 is hooked on the left ear AL of the subject A. Although not shown in FIG. 2, the right ear hook 122 (see FIG. 1) of the second arm 112 is hooked on the right ear of the subject A.

[0022] When the wearable device 100 is worn, the base 130 is located at the back of the head AB of the subject A. As described below, the base 130 contains the signal processing device 120 (see FIG. 5) and has a certain weight. The left ear hook 121 and the right ear hook 122 are respectively hooked on the left ear and right ear of the subject A. The weight of the base 130 and other components allows the subject A to wear the wearable device 100 stably.

[0023] Fig. 3 is a front view of subject A wearing wearable device 100. In the example of Fig. 3, a first sensor 101, a second sensor 102, a fourth sensor 104, and a fifth sensor 105 are attached to the face of subject A. These sensors are attached to, for example, the zygomatic muscles or the corrugator supercilii muscles to detect the myoelectric potential of the zygomatic muscles or the corrugator supercilii muscles.

[0024] FIG. 4 is a view of the wearable device 100 as viewed from the back of the base 130. In FIG. 4, wiring and sensors are omitted. A line that bisects the base 130 of the wearable device 100 is referred to as a "line M." The first arm 111 and the second arm 112 are formed in a shape that is line-symmetrical with respect to the base 130. That is, the first arm 111 and the second arm 112 are formed so that their lengths in the extension direction are the same. Therefore, the subject A can wear the wearable device 100 in a well-balanced manner.

[0025] [Detection system] 5 is a block diagram of a detection system 1000 including a wearable device 100 of the present embodiment. The detection system 1000 of the present embodiment includes the wearable device 100, a control device 500, and a display device 600. The "display device 600" of the present embodiment corresponds to the "output device" of the present disclosure.

[0026] The signal processing device 120 mainly includes a CPU (Central Processing Unit) 1201, a transmitting unit 1202, a storage device 1203, and an interface unit 1204. The components are connected to each other via a data bus.

[0027] The control device 500 mainly includes a CPU 501 and a storage device 502. The storage device 1203 and the storage device 502 are configured with a ROM (Read Only Memory), a RAM (Random Access Memory), and the like.

[0028] The base 130 has a connection port 1121 and a connection port 1122. Furthermore, the signal processing device 120 is housed inside the base 130. In the following, among both ends of the above-mentioned wirings (first wiring 141 to sixth wiring 146), the end opposite to the end (one end 141A to one end 146A) to which the sensors (first sensor 101 to sixth sensor 106) are connected will be referred to as the “other end”.

[0029] The other end 141B of the first wiring 141, the other end 142B of the second wiring 142, and the other end 143B of the third wiring 143 are detachably connected to a connection port 1121. In addition, the other end 144B of the fourth wiring 144, the other end 145B of the fifth wiring 145, and the other end 146B of the sixth wiring 146 are detachably connected to a connection port 1122. The other ends 141B to 146B and the connection ports 1121 and 1122 are formed of, for example, jacks or connectors.

[0030] That is, the first wiring 141, the second wiring 142, the third wiring 143, the fourth wiring 144, the fifth wiring 145, and the sixth wiring 146 are detachable from the signal processing device 120. Note that the first wiring 141, the second wiring 142, the third wiring 143, the fourth wiring 144, the fifth wiring 145, and the sixth wiring 146 are not detachable from the signal processing device 120, and the first wiring 141, the second wiring 142, the third wiring 143, the fourth wiring 144, the fifth wiring 145, and the sixth wiring 146 may be integrally molded with the signal processing device 120.

[0031] The first sensor 101, the second sensor 102, the fourth sensor 104, and the fifth sensor 105 are attached to the face of the subject A (see FIG. 3) and detect myoelectric potentials corresponding to the locations where they are attached. For example, the first sensor 101, the second sensor 102, the fourth sensor 104, and the fifth sensor 105 output detection signals indicating the detected myoelectric potentials to the signal processing device 120.

[0032] On the other hand, the third sensor 103 and the sixth sensor 106 detect a reference potential that is a reference for the myoelectric potential. The third sensor 103 and the sixth sensor 106 are attached at a location where the reference potential can be detected. The location where the reference potential can be detected is, for example, behind the ear of the subject A. For example, the third sensor 103 is attached behind the left ear of the subject A (see FIG. 2), and the sixth sensor 106 is attached behind the right ear of the subject A. The potential detected by the third sensor 103 and the sixth sensor 106 is set as the reference potential. The third sensor 103 and the sixth sensor 106 output a detection signal indicating the detected reference potential to the signal processing device 120.

[0033] The CPU 1201 converts the myoelectric potentials indicated by the detection signals from the first sensor 101, the second sensor 102, the fourth sensor 104, and the fifth sensor 105 into potentials based on the reference potentials detected by the third sensor 103 and the sixth sensor 106. The CPU 1201, for example, calculates the difference between the myoelectric potentials detected by the first sensor 101 and the second sensor 102 and the potential (reference potential) detected by the third sensor 103. The CPU 1201 also calculates the difference between the myoelectric potentials detected by the fourth sensor 104 and the fifth sensor 105 and the potential (reference potential) detected by the sixth sensor 106. In this way, the CPU 1201 calculates four differential potentials.

[0034] Furthermore, the CPU 1201 executes a process of converting information indicating the converted myoelectric potential into a format that can be received by the control device 500. The CPU 1201 wirelessly transmits the converted signal (control signal) to the control device 500 via the transmission unit 1202. This control signal includes the above-mentioned four differential potentials. Upon receiving the control signal from the wearable device 100, the control device 500 executes a predetermined process in the CPU 501 based on the control signal. The predetermined process is, for example, a process of estimating the emotion of the subject A.

[0035] The CPU 501 of the control device 500 extracts four differential potentials from the control signal transmitted from the wearable device 100. A table in which the four potentials are associated with emotions is generated in advance and stored in the storage device 502. The CPU 502 refers to this table to extract emotions corresponding to the four myoelectric potentials indicated by the control signal. The control device 500 outputs the extracted emotions as an estimation result. The CPU 501 may estimate emotions by inputting the myoelectric potentials of the four parts of the subject A and two reference potentials to a neural network stored in the storage device 502. The control device 500 outputs information indicating the estimation result (estimated emotion) to the display device 600. The "estimation result" in this embodiment corresponds to the "control information" in the present disclosure. The display device 600 displays information indicating the estimation result (estimated emotion). The control device 500 may output the estimation result to a printer and cause the printer to print and output the estimation result on paper. This allows the analyst to recognize subject A's emotions.

[0036] Also, a configuration is conceivable in which the wearable device 100 and the control device 500 are connected by wire, and the wearable device 100 transmits a control signal to the control device 500 via this wiring. However, in this configuration, the wiring connecting the wearable device 100 and the control device 500 may interfere with other objects. Therefore, in this embodiment, the wearable device 100 transmits a control signal wirelessly to the control device 500. This makes it possible to reduce the occurrence of an event in which the wiring interferes with other objects.

[0037] Moreover, the interface unit 1204 accepts a connection of the external storage device 1205 to the wearable device 100. That is, the wearable device 100 can be equipped with the external storage device 1205. The external storage device 1205 is, for example, a Universal Serial Bus (USB) memory. The CPU 1201 executes a process of converting the detection signals from the first sensor 101 to the sixth sensor 106 into a format that can be stored by the external storage device 1205. This process generates detection information. The CPU 1201 stores the detection information (for example, the estimated emotion of the subject A) in the external storage device 1205. This allows the analyst to connect the external storage device 1205 to another device (for example, a personal computer (PC)) and recognize the emotion of the subject A by this other device.

[0038] The system of the above-mentioned non-patent document includes a stationary processing device, a plurality of sensors, and wiring connecting the processing device and each of the plurality of sensors. In this system, long wiring is required to increase the degree of freedom of the subject's position when detecting the subject's body data. However, if the wiring is long, there is a problem that the wiring becomes tangled or interferes with other objects, making it cumbersome to attach the sensor to the subject's face. In addition, in the above-mentioned non-patent document, when the subject performs some movement while the plurality of sensors are attached to the subject, there is a problem that the wiring becomes tangled or interferes with other objects.

[0039] In contrast, the wearable device 100 of the present disclosure can be attached to the head and neck of the subject A, and therefore the wearable device 100 and the control device 500 are independent of each other. The wearable device 100 includes sensors (first sensor 101 to sixth sensor 106) attached to the body of the subject, and wiring (first wiring 141 to sixth wiring 146) connected to the sensors. Therefore, in the wearable device 100 of the present disclosure, the length of the wiring can be shortened compared to the above-mentioned system. As a result, it is possible to reduce the tangled wiring or the interference of the wiring with other objects when attaching the sensors to the head and neck of the subject. Therefore, the wearable device 100 of the present disclosure can improve the ease of attaching the sensors to the head and neck of the subject. In addition, even if the subject performs some kind of movement with multiple sensors attached, it is possible to reduce the tangled wiring or the interference of the wiring with other objects.

[0040] As shown in FIG. 1, the wearable device 100 includes wiring (for example, the first wiring 141 to the third wiring 143) arranged along the first arm 111, and sensors (for example, the first sensor 101 to the third sensor 103) connected to the wiring. The wearable device 100 also includes wiring (for example, the fourth wiring 144 to the sixth wiring 146) arranged along the second arm 112, and sensors (for example, the fourth sensor 104 to the sixth sensor 106) connected to the wiring. Therefore, the subject A wearing the wearable device 100 can attach the sensors protruding from both sides of the subject A's face to the subject A's face. This improves the convenience of attaching the sensors to the subject A's face.

[0041] 4, the first arm 111 and the second arm 112 are symmetrical with respect to the base 130 (line M). Therefore, the subject A can wear the wearable device 100 in a well-balanced manner.

[0042] 1, the tip of first arm 111 is formed with a left ear hook 121 shaped to be hung on the left ear of subject A. The tip of second arm 112 is formed with a right ear hook 122 shaped to be hung on the right ear of subject A. Furthermore, as shown in FIG. 2, when subject A is wearing wearable device 100, base 130 is located at the subject's head and neck (back of the head AB). This allows subject A to wear wearable device 100 stably.

[0043] 5, all of the first wiring 141 to the sixth wiring 146 are detachable from the signal processing device 120. Therefore, for example, unnecessary sensors and wirings can be removed from the wearable device 100, thereby improving the convenience of detecting the physical data of the subject A.

[0044] In the wearable device 100, the first sensor 101, the second sensor 102, the fourth sensor 104, and the fifth sensor 105 detect the myoelectric potential of the subject A. At the same time, the third sensor 103 and the sixth sensor 106 detect the reference potential of the myoelectric potential. Therefore, the wearable device 100 can calculate the potential based on the reference potential (the above-mentioned differential potential).

[0045] [About the groove] Next, the grooves formed on the surface of the first arm 111 will be described. Wiring is arranged in the grooves. FIG. 6 is an enlarged view of the left ear hook portion 121 of the first arm 111. As shown in FIG. 6, the first arm 111 is formed with a first groove 1161, a second groove 1162, a third groove 1163, a fourth groove 1164, and a fifth groove 1165. In the example of FIG. 6, the first groove 1161, the second groove 1162, the third groove 1163, and the fifth groove 1165 are shaped along the extension direction of the first arm 111. The first arm 111 also includes an extension portion 111A that extends linearly or approximately linearly.

[0046] The first groove 1161 is formed from the point where the first arm 111 is connected to the base 130 to the edge 111B of the extension 111A. The second groove 1162 is formed along the extension direction of the left ear hook 121. The first groove 1161 and the second groove 1162 are in a relationship in which one groove is separated. The third groove 1163 is formed across the extension 111A and the left ear hook 121. The fourth groove 1164 is formed at the tip of the left ear hook 121. The third groove 1163 and the fourth groove 1164 are in a relationship in which one groove is separated. The fifth groove 1165 is formed from the point where the first arm 111 is connected to the base 130 to the edge 111C of the extension 111A.

[0047] FIG. 7 is an enlarged view of the left ear hook part 121 in a state where the wiring is arranged in the groove. In the example of FIG. 7, the first wiring 141 is arranged in the first groove 1161 and the second groove 1162. For example, the first wiring 141 is arranged in the first groove 1161. At the same time, a part of the first wiring 141 different from the part arranged in the first groove 1161 is arranged in the second groove 1162 in the extension direction of the first wiring. As a result, a slack 141S of the first wiring 141 is formed between the first groove 1161 and the second groove 1162. In this way, the positional relationship between the first groove 1161 and the second groove 1162 is such that, when the first wiring 141 is arranged in the first groove 1161 and the second groove 1162, the slack 141S of the first wiring 141 can be formed between the first groove 1161 and the second groove 1162. In this manner, the first wiring 141 is disposed in a plurality of grooves (in the example of FIG. 7, the first groove 1161 and the second groove 1162). In addition, the first sensor 101 is connected to one end of the protruding portion 141T of the first wiring 141 that protrudes from the first arm 111.

[0048] The second wiring 142 is disposed in the third groove 1163 and the fourth groove 1164. A slack 142S of the second wiring 142 is formed between the third groove 1163 and the fourth groove 1164. In this manner, the positional relationship between the third groove 1163 and the fourth groove 1164 is such that a slack 142S of the second wiring 142 can be formed between the second groove 1162 and the fourth groove 1164 in a state in which the second wiring 142 is disposed in the third groove 1163 and the fourth groove 1164. In this manner, the second wiring 142 is disposed in a plurality of grooves (the third groove 1163 and the fourth groove 1164 in the example of FIG. 7). In addition, the second sensor 102 is connected to one end of the protruding portion 142T of the second wiring 142 protruding from the first arm 111.

[0049] The third wiring 143 is disposed in the fifth groove portion 1165. Unlike the first wiring 141 and the second wiring 142, the third wiring 143 is not disposed in a plurality of groove portions, but is disposed in one fifth groove portion 1165. Therefore, no slack is formed in the third wiring 143.

[0050] In this manner, first wiring 141 to third wiring 143 are disposed in the groove portion, and thereby disposed along first arm 111. Therefore, first wiring 141 to third wiring 143 can be disposed along first arm 111 with a relatively simple configuration.

[0051] Next, the function of the slack 141S will be described. FIG. 8 shows the first groove 1161, the second groove 1162, and the fifth groove 1163 of the first arm 111. 1165 As described in FIG. 7, the first wiring 141 is disposed in the first groove portion 1161 and the second groove portion 1162 The third wiring 143 is disposed in the fifth groove portion 141S, and the slack 141S is formed. 1165 In first wiring 141, the length of protruding portion 141T protruding from first arm 111 is referred to as “length L1.” In addition, in third wiring 143, the length of protruding portion 143T protruding from first arm 111 is referred to as “length L3.”

[0052] Here, the first wiring 141 is composed of an extending conductor and a sheath that covers the conductor and extends in the extension direction of the conductor. The sheath is composed of an insulator having rigidity and elasticity. Therefore, the first wiring 141 has rigidity and elasticity. The sheath is mainly made of chloroprene rubber, polyvinyl chloride, polyethylene, etc.

[0053] As described above, the other end 141B of the first wiring 141 is connected (fixed) to the signal processing device 120. Therefore, when the slack 141S of the first wiring 141 is pushed in the direction of the arrow α1 by the subject A or the like, the protruding portion 141T of the first wiring 141 is pushed out in the direction of the arrow β1 because the first wiring 141 has rigidity and the other end 141B of the first wiring 141 is fixed. In other words, the length L1 of the protruding portion 141T of the first wiring 141 becomes longer.

[0054] Also, when the protruding portion 141T of the first wiring 141 is pulled in the direction of the arrow β1 by the subject A or the like, the slack 141S moves in the direction of the arrow α1 and the length L1 of the protruding portion 141T of the first wiring 141 becomes longer.

[0055] On the other hand, when the slack 141S of the first wiring 141 is pulled in the direction of the arrow α2 by the subject A or the like, the protruding portion 141T of the first wiring 141 is pulled in the direction of the arrow β2. That is, the length L1 of the protruding portion 141T of the first wiring 141 is shortened. Also, when the protruding portion 141T of the first wiring 141 is pushed in the direction of the arrow β2 by the subject A or the like, the slack 141S moves in the direction of the arrow α2 and the length L1 of the protruding portion 141T of the first wiring 141 is shortened.

[0056] In this manner, in the wearable device 100, the first adjustment portion 1181 that can adjust the length of the protruding portion 141T of the first wiring 141 is formed on the first arm 111. Also, as shown in FIG. 6, the first adjustment portion 1181 is formed by adjusting the length of the first groove portion 1161 and the second groove portion 1162 In addition, the length L1 of the protruding portion 141T can be adjusted by the subject A or the like adjusting the slack 141S.

[0057] Generally, there are individual differences in the size of the subject's face and the arrangement of the facial muscles. One method for making the sensor attachable to any subject is to make the wiring sufficiently long. However, if the wiring is excessively long, problems occur in that the wiring becomes tangled or collides with other objects. In response to this, the wearable device 100 has a first adjustment unit 1181 that can adjust the length L1 of the protruding portion 141T. Therefore, by having the first adjustment unit 1181, the wearable device 100 can reduce the occurrence of such problems and improve the convenience of the user.

[0058] In addition, the first adjustment portion 1181 is a first groove portion 1161 and the second groove portion 1162 Therefore, first adjustment portion 1181 can be formed with a relatively simple structure.

[0059] Although not particularly shown, an adjustment section capable of adjusting protruding portion 142T of second wiring 142 is also formed in a configuration similar to that of first adjustment section 1181. Specifically, based on slack 142S formed in second wiring 142, protruding portion 142T of second wiring 142 is adjustable.

[0060] Next, the third wiring 143 will be described with reference to FIG. 8. As described above, the third wiring 143 is not loose. As described above, the third sensor 103 connected to one end 143A of the third wiring 143 detects the reference potential. In general, the location where the reference potential can be detected on the face of the subject is generally fixed. Therefore, since there is little need to change the location where the reference potential is detected depending on the subject, there is no particular problem even if the length of the protruding portion 143T of the third wiring 143 is fixed. Therefore, in this embodiment, an adjustment portion for adjusting the length of the protruding portion 143T of the third wiring 143 is not formed. That is, the groove in which the third wiring 143 is arranged is one fifth groove 1175. This makes it possible to avoid forming an unnecessary adjustment portion (unnecessary groove). It is to be noted that even if an adjustment portion for the third wiring 143 is not provided, the protruding portion of the third wiring 143 from the first arm 111 may be adjusted by the extra length of the third wiring 143.

[0061] FIG. 9 is an enlarged view of the right ear hook portion 122 of the second arm 112. As shown in FIG. 9, the second arm 112 is formed with a first groove portion 1171, a second groove portion 1172, a third groove portion 1173, a fourth groove portion 1174, and a fifth groove portion 1175. As described in FIG. 4, the first arm 111 and the second arm 112 are symmetrical with respect to the base portion 130 (line M). Therefore, the first groove portion 1171 is formed opposite the first groove portion 1161, the second groove portion 1172 is formed opposite the second groove portion 1162, the third groove portion 1173 is formed opposite the third groove portion 1163, the fourth groove portion 1174 is formed opposite the fourth groove portion 1164, and the fifth groove portion 1175 is formed opposite the fifth groove portion 1165.

[0062] Although not particularly shown, the fourth wiring 144 is disposed in the first groove 1171 and the second groove 1172. A slack is formed in the fourth wiring 144 between the first groove 1171 and the second groove 1172. The fifth wiring 145 is disposed in the third groove 1173 and the fourth groove 1174. A slack is formed in the fifth wiring 145 between the third groove 1173 and the fourth groove 1174. The sixth wiring 146 is disposed in the fifth groove 1175. A slack is not formed in the sixth wiring 146.

[0063] Therefore, for the second arm 112 as well, an adjustment section capable of adjusting the length of the portion of the fourth wiring 144 protruding from the second arm 112 and an adjustment section capable of adjusting the length of the portion of the fifth wiring 145 protruding from the second arm 112 are formed. For example, the second adjustment section 1182 is configured by a first groove portion 1171 and a second groove portion 1172. In addition, the length of the portion of the fourth wiring 144 protruding from the second arm 112 can be adjusted based on the slack of the fourth wiring 144 formed between the first groove portion 1171 and the second groove portion 1172.

As a result, it is possible to reduce the first wiring 141 coming off the first groove 1161. As described above, the first wiring 141 has elasticity. Therefore, in a state in which the first wiring 141 is not arranged in the first groove 1161, the user can arrange the first wiring 141 in the first groove 1161 by pushing the first wiring 141 from the gap P between the claw portion 1180 and the first groove 1161. Furthermore, when the first wiring 141 is placed in the first groove portion 1161, the user can pull the first wiring 141, thereby removing the first wiring 141 from the gap P and removing the first wiring 141 from the first groove portion 1161.

[0065] One or more claws 1180 are formed at predetermined positions of the first groove 1161. Furthermore, one or more claws 1180 are formed in each of the second groove 1162 to the fifth groove 1165 and the first groove 1171 to the fifth groove 1175.
