The connection part 120c and the second connection part 120d are configured by a second wiring part 120b for electrically connecting the connection part 120c and the second connection part 120d.
　ここで、図２に示すように、第１の接続部１１０ｃ、１１０ｄ及び第２の接続部１２０ｃ、１２０ｄは、第１の接続部１１０ｃと第１の接続部１１０ｄを結ぶ直線上の中点であり、かつ、第２の接続部１２０ｃと第２の接続部１２０ｄを結ぶ中点である点を中心Ｏとする円Ｃ１上に配置される。更に、第１の接続部１１０ｃと第１の接続部１１０ｄとの第１の電極対、及び、第２の接続部１２０ｃと第２の接続部１２０ｄとの第２の電極対は、中心Ｏについてそれぞれ点対称に配置される。また、本実施の形態では、第１の接続部１１０ｃ、１１０ｄ、第２の接続部１２０ｃ、１２０ｄの各電極は、円Ｃ１上において等間隔でない間隔で配置される。 Here, as shown in FIG. 2, the first connection portions 110c and 110d and the second connection portions 120c and 120d are midpoints on a straight line connecting the first connection portion 110c and the first connection portion 110d. And a circle C1 having a center O at a point that is a midpoint connecting the second connection part 120c and the second connection part 120d. Further, the first electrode pair of the first connection part 110c and the first connection part 110d and the second electrode pair of the second connection part 120c and the second connection part 120d are about the center O. They are arranged point-symmetrically. Moreover, in this Embodiment, each electrode of 1st connection part 110c, 110d and 2nd connection part 120c, 120d is arrange | positioned on the circle | round | yen C1 at the space | interval which is not equal intervals.
　また、図２に示すように、距離Ａは、第１の接続部１１０ｃの中心と第２の接続部１２０ｄの中心とを結んだ線分（或いは、第２の接続部１２０ｃの中心と第１の接続部１１０ｄの中心を結んだ線分）の長さである。また、距離Ｂは、第１の接続部１１０ｃの中心と第２の接続部１２０ｃの中心とを結んだ線分（或いは、第２の接続部１２０ｄの中心と第１の接続部１１０ｄの中心とを結んだ線分）の長さである。言い換えると、距離Ａは、第１の接続部１１０ｃと第１の接続部１１０ｄとの垂直距離であり、第２の接続部１２０ｃと第２の接続部１２０ｄとの垂直距離でもある。距離Ｂは、第１の接続部１１０ｃと第１の接続部１１０ｄとの水平距離であり、第２の接続部１２０ｃと第２の接続部１２０ｄとの水平距離でもある。このとき、距離Ａと距離Ｂとは異なる長さである。図２に示す例では、長さ距離Ａ＞距離Ｂとしているが、距離Ｂ＞距離Ａとなるように構成してもよい。 Further, as shown in FIG. 2, the distance A is a line segment connecting the center of the first connection part 110c and the center of the second connection part 120d (or the center of the second connection part 120c and the first The length of the line segment connecting the centers of the connecting portions 110d. The distance B is a line segment connecting the center of the first connection part 110c and the center of the second connection part 120c (or the center of the second connection part 120d and the center of the first connection part 110d). The length of the line segment connecting In other words, the distance A is a vertical distance between the first connecting portion 110c and the first connecting portion 110d, and is also a vertical distance between the second connecting portion 120c and the second connecting portion 120d. The distance B is a horizontal distance between the first connection portion 110c and the first connection portion 110d, and is also a horizontal distance between the second connection portion 120c and the second connection portion 120d. At this time, the distance A and the distance B are different lengths. In the example shown in FIG. 2, the length distance A> the distance B is set. However, the distance B> the distance A may be set.
　第１の接触部位１１０ａおよび第２の接触部位１２０ａは、銀などの金属や、カーボン、導電性有機物などを表面にコーティングした導電性繊維などにより、パッド状に形成される。これにより、導電性を有しつつ、肌との良好な接触性を確保することができる。図１Ａ及び図１Ｂに示すように、第１の接触部位１１０ａは、ユーザがウェア１００を装着した場合に右側に位置するように配置され、第２の接触部位１２０ａは、左側に位置するように配置される。 The first contact portion 110a and the second contact portion 120a are formed in a pad shape by a conductive fiber having a surface coated with a metal such as silver, carbon, or a conductive organic material. Thereby, favorable contact property with skin can be ensured while having conductivity. As shown in FIGS. 1A and 1B, when the user wears the wear 100, the first contact part 110a is arranged on the right side, and the second contact part 120a is located on the left side. Be placed.
　第１の配線部１１０ｂおよび第２の配線部１２０ｂも、第１の接触部位１１０ａおよび第２の接触部位１２０ａと同様に導電性繊維で形成される。もしくは、肌との接触に違和感がないような構成で形成される場合は、金属製のリードワイヤなどで形成されても構わない。 The first wiring part 110b and the second wiring part 120b are also formed of conductive fibers in the same manner as the first contact part 110a and the second contact part 120a. Alternatively, in the case where the contact with the skin is formed so that there is no sense of incongruity, it may be formed with a metal lead wire or the like.
　第１の接続部１１０ｃ、１１０ｄおよび第２の接続部１２０ｃ、１２０ｄは、着脱相手である生体センサ装置２００との電気的接続が自在にできるように、金属性のボタン、フックなどで形成されるか、磁気引力を有する金属材料などで形成される。 The first connection portions 110c and 110d and the second connection portions 120c and 120d are formed of metallic buttons, hooks, or the like so that electrical connection with the biosensor device 200, which is the attachment / detachment partner, can be freely made. Or a metal material having magnetic attraction.
　生体センサ装置２００は、図２に示すように、第１の装置電極２１０ｃ、２１０ｄ、第２の装置電極２２０ｃ、２２０ｄを備える。第１の装置電極２１０ｃはウェア１００の第１の接続部１１０ｃと、第１の装置電極２１０ｄは第１の接続部１１０ｄと、第２の装置電極２２０ｃは第２の接続部１２０ｃと、第２の装置電極２２０ｄは第２の接続部１２０ｄと、それぞれ着脱可能な構造で機械的かつ電気的に接続される。そして、生体センサ装置２００の第１の装置電極２１０ｃ、２１０ｄ及び第２の装置電極２２０ｃ、２２０ｄの配置は、ウェア１００の第１の接続部１１０ｃ、１１０ｄ及び第２の接続部１２０ｃ、１２０ｄの配置と同一である。 The biosensor device 200 includes first device electrodes 210c and 210d and second device electrodes 220c and 220d, as shown in FIG. The first device electrode 210c is the first connection portion 110c of the wear 100, the first device electrode 210d is the first connection portion 110d, the second device electrode 220c is the second connection portion 120c, and the second The device electrode 220d is mechanically and electrically connected to the second connecting portion 120d with a detachable structure. The arrangement of the first device electrodes 210c and 210d and the second device electrodes 220c and 220d of the biosensor device 200 is the arrangement of the first connection portions 110c and 110d and the second connection portions 120c and 120d of the wear 100. Is the same.
　生体センサ装置２００は、第１のウェア電極１１０及び第２のウェア電極１２０を介して検出した心電信号を演算処理および通信する機能を有する。ウェア１００と生体センサ装置２００とが一体となって、ウェア１００を着たユーザの心拍由来の心電を検出するシステムを構成する。 The biosensor device 200 has a function of performing arithmetic processing and communication of an electrocardiogram signal detected via the first wear electrode 110 and the second wear electrode 120. The wear 100 and the biosensor device 200 are integrated to constitute a system for detecting an electrocardiogram derived from the heartbeat of the user wearing the wear 100.
　ここで、図１Ａ及び図１Ｂに示すように、第２のウェア電極１２０はプラスの電気極性を有し、第１のウェア電極１１０はマイナスの電気極性を有している。そのため、ウェア１００に装着する生体センサ装置２００の電気極性が第１のウェア電極１１０及び第２のウェア電極１２０の電気極性と一致していなければ、生体センサ装置２００は正しい心電情報を得ることができない。 Here, as shown in FIGS. 1A and 1B, the second wear electrode 120 has a positive electrical polarity, and the first wear electrode 110 has a negative electrical polarity. Therefore, if the electrical polarity of the biosensor device 200 attached to the wear 100 does not match the electrical polarity of the first wear electrode 110 and the second wear electrode 120, the biosensor device 200 obtains correct electrocardiogram information. I can't.
　一方、生体センサ装置２００をウェア１００に装着する度に、電極の電気極性が一致しているか否かを確認するのは、ユーザにとって煩わしい作業となる。本開示の生体センサ装置２００の第１の装置電極２１０ｃ、２１０ｄ及び第２の装置電極２２０ｃ、２２０ｄは、円Ｃ１上に等間隔ではない間隔で配置される。さらに、第１の装置電極２１０ｃと第１の装置電極２１０ｄ及び第２の装置電極２２０ｃと第２の装置電極２２０ｄは、円Ｃ１の中心Ｏについて点対称に配置される。これにより、生体センサ装置２００をウェア１００に装着する向きをユーザが特に意識することなく、常に正しい心電情報を得ることができるようになる。 On the other hand, it is troublesome for the user to check whether or not the electrical polarities of the electrodes match each time the biosensor device 200 is mounted on the wear 100. The first device electrodes 210c and 210d and the second device electrodes 220c and 220d of the biosensor device 200 of the present disclosure are arranged on the circle C1 at intervals other than equal intervals. Further, the first device electrode 210c, the first device electrode 210d, the second device electrode 220c, and the second device electrode 220d are arranged point-symmetrically with respect to the center O of the circle C1. As a result, correct electrocardiographic information can always be obtained without the user being particularly aware of the direction in which the biosensor device 200 is mounted on the wear 100.
　図３は、ウェア１００上の電極と生体センサ装置２００の電気的構成図である。 FIG. 3 is an electrical configuration diagram of the electrodes on the wear 100 and the biosensor device 200.
　生体センサ装置２００には、心電信号を電気的に処理するための回路が内蔵されている。すなわち、生体センサ装置２００は、第１の装置電極２１０ｃ、２１０ｄ、第２の装置電極２２０ｃ、２２０ｄ、アナログ信号処理を行うＡＦＥ（Ａｎａｌｏｇ　Ｆｒｏｎｔ　Ｅｎｄ）回路２３０、デジタル演算処理を行うＣＰＵ２４０、他のデバイスとデータ通信を行う通信部２５０、電源部（不図示）などから構成される。 The biosensor device 200 includes a circuit for electrically processing an electrocardiogram signal. That is, the biosensor device 200 includes a first device electrode 210c, 210d, a second device electrode 220c, 220d, an AFE (Analog Front End) circuit 230 that performs analog signal processing, a CPU 240 that performs digital arithmetic processing, and other devices. And a communication unit 250 that performs data communication, a power supply unit (not shown), and the like.
　図３に示すように、第１の接触部位１１０ａは第１の配線部１１０ｂを介して第１の接続部１１０ｃ、１１０ｄと接続する。また、第２の接触部位１２０ａは第２の配線部１２０ｂを介して第２の接続部１２０ｃ、１２０ｄと接続する。生体センサ装置２００において第１の装置電極２１０ｃ、２１０ｄ及び第２の装置電極２２０ｃ、２２０ｄはＡＦＥ回路２３０と接続する。 As shown in FIG. 3, the first contact part 110a is connected to the first connection parts 110c and 110d via the first wiring part 110b. The second contact portion 120a is connected to the second connection portions 120c and 120d via the second wiring portion 120b. In the biosensor device 200, the first device electrodes 210 c and 210 d and the second device electrodes 220 c and 220 d are connected to the AFE circuit 230.
　なお、第１の接続部１１０ｃ、１１０ｄが、両方ともウェア１００内で第１の配線部１１０ｂにより電気的に第１の接触部位１１０ａに接続されている場合は、第１の装置電極２１０ｃ、２１０ｄは、生体センサ装置２００内で互いに電気的に接続されていても接続されていなくてもどちらでも構わない。 When both the first connection portions 110c and 110d are electrically connected to the first contact portion 110a by the first wiring portion 110b in the wear 100, the first device electrodes 210c and 210d are used. May be electrically connected or not connected to each other in the biosensor device 200.
　同様に、第２の接続部１２０ｃ、１２０ｄが、両方ともウェア１００内で第２の配線部１２０ｂにより電気的に第２の接触部位１２０ａに接続されている場合は、第２の装置電極２２０ｃ、２２０ｄは、生体センサ装置２００内で互いに電気的に接続されていても接続されていなくてもどちらでも構わない。 Similarly, when the second connection parts 120c and 120d are both electrically connected to the second contact part 120a by the second wiring part 120b in the wear 100, the second device electrode 220c, 220d may be either connected or not electrically connected to each other in the biosensor device 200.
　また、逆に、第１の装置電極２１０ｃ、２１０ｄが、両方とも生体センサ装置２００内で電気的にＡＦＥ回路２３０に接続されている場合は、第１の接続部１１０ｃ、１１０ｄは、ウェア１００内で互いに電気的に接続されていても接続されていなくてもどちらでも構わない。 Conversely, when both the first device electrodes 210 c and 210 d are electrically connected to the AFE circuit 230 in the biosensor device 200, the first connection portions 110 c and 110 d are connected to the wear 100. It does not matter whether they are electrically connected to each other or not.
　同様に、第２の装置電極２２０ｃ、２２０ｄが、両方とも生体センサ装置２００内で電気的にＡＦＥ回路２３０に接続されている場合は、第２の接続部１２０ｃ、１２０ｄは、ウェア１００内で互いに電気的に接続されていても接続されていなくてもどちらでも構わない。 Similarly, when the second device electrodes 220 c and 220 d are both electrically connected to the AFE circuit 230 in the biosensor device 200, the second connection portions 120 c and 120 d are mutually connected in the wear 100. It does not matter whether it is electrically connected or not.
　人体から発せられる心電信号は、ウェア１００に形成され、かつ、人体と接触する第１の接触部位１１０ａと第２の接触部位１２０ａで検出される。検出された心電信号は、第１の配線部１１０ｂ及び第２の配線部１２０ｂを介して、第１の接続部１１０ｃ、１１０ｄ、及び、第２の接続部１２０ｃ、１２０ｄに伝達される。そして、心電信号は、第１の接続部１１０ｃ、１１０ｄ、及び、第２の接続部１２０ｃ、１２０ｄに接続された生体センサ装置２００の第１の装置電極２１０ｃ、２１０ｄ、及び、第２の装置電極２２０ｃ、２２０ｄを通じてＡＦＥ回路２３０に流れ込む。 An electrocardiographic signal emitted from the human body is formed on the wear 100 and detected at the first contact portion 110a and the second contact portion 120a that come into contact with the human body. The detected electrocardiogram signal is transmitted to the first connection parts 110c and 110d and the second connection parts 120c and 120d via the first wiring part 110b and the second wiring part 120b. Then, the electrocardiographic signals are the first device electrodes 210c, 210d and the second device of the biosensor device 200 connected to the first connection portions 110c and 110d and the second connection portions 120c and 120d. It flows into the AFE circuit 230 through the electrodes 220c and 220d.
　ＡＦＥ回路２３０は、入力された心電信号に対してアナログ的なフィルタ処理、増幅処理などを施す。その後、ＡＦＥ回路２３０は、心電信号をアナログからデジタルの信号にＡＤ変換し、デジタル化された心電信号をＣＰＵ２４０に送る。 The AFE circuit 230 performs analog filter processing, amplification processing, and the like on the input electrocardiogram signal. Thereafter, the AFE circuit 230 AD converts the electrocardiogram signal from an analog signal to a digital signal, and sends the digitized electrocardiogram signal to the CPU 240.
　ＣＰＵ２４０は、デジタル化された心電信号に対して、デジタル的なフィルタ処理や、その他様々なデジタル演算処理を施す。その後、ＣＰＵ２４０は、デジタル処理された心電信号を通信部２５０に送る。 The CPU 240 performs digital filter processing and various other digital arithmetic processing on the digitized electrocardiogram signal. Thereafter, the CPU 240 sends the digitally processed electrocardiogram signal to the communication unit 250.
　通信部２５０は、Ｂｌｕｅｔｏｏｔｈ（登録商標）やＷｉＦｉなどの無線通信手段か、もしくはＵＳＢなどの有線通信手段により構成される。通信部２５０は、デジタル処理された心電信号を、表示部などを有する外部のデバイスに送信する。デジタル処理された心電信号を受信した外部のデバイスは、表示部に心電波形を描画して表示する。なお、通信部２５０は、心電信号をリアルタイムに画部のデバイスに送信してもよいし、メモリに記録された心電信号のデータを必要に応じて送信することもできる。 The communication unit 250 includes a wireless communication unit such as Bluetooth (registered trademark) or WiFi, or a wired communication unit such as USB. The communication unit 250 transmits the digitally processed electrocardiogram signal to an external device having a display unit and the like. The external device that has received the digitally processed ECG signal draws and displays the ECG waveform on the display unit. The communication unit 250 may transmit the electrocardiogram signal to the image device in real time, or may transmit the electrocardiogram signal data recorded in the memory as necessary.
　電源部（不図示）は、ＡＦＥ回路２３０、ＣＰＵ２４０、通信部２５０が電気的に駆動できるように電源を供給する。電源部として、多くの場合は、ノイズの抑制や携帯性などの観点から電池が使われるが、ＡＣアダプタなどによる電源供給の構成でも構わない。 A power supply unit (not shown) supplies power so that the AFE circuit 230, the CPU 240, and the communication unit 250 can be electrically driven. In many cases, a battery is used as the power supply unit from the viewpoint of noise suppression and portability, but a power supply configuration using an AC adapter or the like may be used.
　心電波形は図４に示すような形状をしており、プラスマイナスの極性を有している。それゆえ、生体センサ装置２００が正しい極性で心電信号を検出しない場合には、心電波形の極性が反転してしまい、生体センサ装置２００内での電気的な処理に不備が生じたり、通信された外部デバイスに表示される心電波形の極性が反転してしまう問題がある。 The electrocardiogram waveform has a shape as shown in FIG. 4 and has a plus or minus polarity. Therefore, when the biosensor device 200 does not detect an electrocardiogram signal with the correct polarity, the polarity of the electrocardiogram waveform is reversed, resulting in inadequate electrical processing within the biosensor device 200 or communication. There is a problem that the polarity of the electrocardiogram waveform displayed on the external device is reversed.
　そこで、本実施の形態にかかる生体センサ装置２００の電極構成によれば、同極性の電極対が同一の円上に点対称に配置されており、正規の向きと、正規の向きとは１８０度異なる向き以外には構造的に装着できない。また、正規の向きとは１８０度異なる向きに装着したとしても、正規の向きで装着した場合と電極の極性が同じになるため、ウェア１００から生体センサ装置２００に送られる心電信号は常に正しい極性となる。 Therefore, according to the electrode configuration of biosensor device 200 according to the present exemplary embodiment, electrode pairs having the same polarity are arranged point-symmetrically on the same circle, and the normal direction and the normal direction are 180 degrees. It cannot be structurally installed except in different directions. Moreover, even if it is attached in a direction different from the normal direction by 180 degrees, the polarity of the electrode is the same as that in the normal direction, so that the electrocardiogram signal sent from the wear 100 to the biosensor device 200 is always correct. Polarity.
　つまり、生体センサ装置２００がウェア１００に対してどちらの向きに接続されても、ＣＰＵ２４０は、正しい極性に基づいて心電波形を処理することができるため、ユーザは、生体センサ装置２００をウェア１００に装着する際における向きを気にする煩わしさを解消することができる。 That is, since the CPU 240 can process the electrocardiogram waveform based on the correct polarity regardless of which direction the biosensor device 200 is connected to the wear 100, the user can attach the biosensor device 200 to the wear 100. The troublesomeness of worrying about the direction when wearing the device can be eliminated.

　実施の形態１とは、ウェア１０１の第２のウェア電極１２１及び生体センサ装置２０１の第２の装置電極２２１ｃ、２２１ｄの配置が異なる。即ち、第２の接続部１２１ｃ、１２１ｄ及び第２の装置電極２２１ｃ、２２１ｄは、円Ｃ１と中心Ｏが同じ同心円で、円Ｃ１より半径の小さい円Ｃ２上に配置される。また、第２の接続部１２１ｃ、１２１ｄ及び第２の装置電極２２１ｃ、２２１ｄは、円Ｃ１と中心Ｏについて点対称に配置される。そして、ウェア１０１に生体センサ装置２０１を取り付ける場合に、第２の接続部１２１ｃと第２の装置電極２２１ｃが接続され、第２の接続部１２１ｄと第２の装置電極２２１ｄが接続される。 The first wear electrode 121 of the wear 101 and the second device electrodes 221c and 221d of the biosensor device 201 are different from the first embodiment. That is, the second connection portions 121c and 121d and the second device electrodes 221c and 221d are arranged on a circle C2 having a concentric circle having the same center O as the circle C1 and having a smaller radius than the circle C1. The second connection parts 121c and 121d and the second device electrodes 221c and 221d are arranged point-symmetrically with respect to the circle C1 and the center O. And when attaching the biosensor apparatus 201 to the wear 101, the 2nd connection part 121c and the 2nd apparatus electrode 221c are connected, and the 2nd connection part 121d and the 2nd apparatus electrode 221d are connected.

　上記構成を採用することにより、実施の形態１と同様に、ウェア１０１に生体センサ装置２０１を装着する場合、装着する向きが１８０度異なっても、同極性の電極同士が接続されるので、電極の極性を誤って装着されることがない。そのため、ウェア１０１から生体センサ装置２０１に送られる心電信号は常に正しい極性となる。 By adopting the above configuration, as in the first embodiment, when the biosensor device 201 is mounted on the wear 101, the electrodes having the same polarity are connected even if the mounting direction is different by 180 degrees. The polarity will not be installed by mistake. Therefore, the electrocardiogram signal sent from the wear 101 to the biosensor device 201 always has the correct polarity.
　なお、図５に示す例では、第１の接続部１１０ｃ、１１０ｄ及び第１の装置電極２１０ｃ、２１０ｄに対して第２の接続部１２１ｃ、１２１ｄ及び第２の装置電極２２１ｃ、２２１ｄが半径の小さい同心円上に配置されるが、逆に、第２の接続部及び第２の装置電極に対して第１の接続部及び第１の装置電極を半径の小さい同心円上に配置することもできる。 In the example shown in FIG. 5, the second connection portions 121c and 121d and the second device electrodes 221c and 221d have a smaller radius than the first connection portions 110c and 110d and the first device electrodes 210c and 210d. Although arranged on concentric circles, conversely, the first connecting portion and the first device electrode may be arranged on concentric circles having a small radius with respect to the second connecting portion and the second device electrode.
　また、図５に示す例において、第２の接続部１２１ｃ、１２１ｄ及び第２の装置電極２２１ｃ、２２１ｄを円Ｃ２の円周方向に移動させて、第１の接続部１１０ｃと第１の接続部１１０ｄとを通る直線上及び第１の装置電極２１０ｃと第１の装置電極２１０ｄを通る直線上にそれぞれ配置することもできる。即ち、第１の接続部１１０ｃ、１１０ｄ、第２の接続部１２１ｃ、１２１ｄ及び第１の装置電極２１０ｃ、２１０ｄ、第２の装置電極２２１ｃ、２２１ｄが、それぞれ一直線上に並ぶように配置することができる。 Further, in the example shown in FIG. 5, the second connection portions 121c and 121d and the second device electrodes 221c and 221d are moved in the circumferential direction of the circle C2, so that the first connection portion 110c and the first connection portion are moved. 110d and a straight line passing through the first device electrode 210c and the first device electrode 210d, respectively. That is, the first connection portions 110c and 110d, the second connection portions 121c and 121d, the first device electrodes 210c and 210d, and the second device electrodes 221c and 221d may be arranged in a straight line. it can.

FIG. 6 is an enlarged view of the electrodes of the wear 102 and the biosensor device 202 according to the electrocardiogram detection system 12 of the third embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
　実施の形態１とは、ウェア１０２の第２のウェア電極１２２及び生体センサ装置２０２の第２の装置電極２２２ｃの配置が異なる。第２の接続部及び第２の装置電極はそれぞれ１つずつであり、図６に示すように、第２の接続部１２２ｃ及び第２の装置電極２２２ｃは円Ｃ１の中心Ｏに配置される。即ち、ウェア１０２の第１の接続部１１０ｃ、１１０ｄと第２の接続部１２２ｃ、及び生体センサ装置２０２の第１の装置電極２１０ｃ、２１０ｄと第２の装置電極２２２ｃは、それぞれ一直線上に配置される。そして、ウェア１０２に生体センサ装置２０２を取り付ける場合に、第２の接続部１２１ｃと第２の装置電極２２１ｃが接続される。 The arrangement of the second wear electrode 122 of the wear 102 and the second device electrode 222c of the biosensor device 202 is different from the first embodiment. One second connection portion and one second device electrode are provided, and as shown in FIG. 6, the second connection portion 122c and the second device electrode 222c are arranged at the center O of the circle C1. That is, the first connection portions 110c and 110d and the second connection portion 122c of the wear 102 and the first device electrodes 210c and 210d and the second device electrode 222c of the biosensor device 202 are arranged in a straight line.

　ウェア１０２と生体センサ装置２０２との電気的構成は、実施の形態１の図３において、第２の接続部１２０ｄ及び第２の装置電極２２０ｄを削除するとともに、第２の接続部１２０ｃ及び第２の装置電極２２０ｃを、それぞれ第２の接続部１２２ｃ及び第２の装置電極２２２ｃに置き換えたものになる。 The electrical configuration of the wear 102 and the biosensor device 202 is the same as that of FIG. 3 of the first embodiment except that the second connection portion 120d and the second device electrode 220d are deleted, and the second connection portion 120c and the second sensor electrode 202d. The device electrode 220c is replaced with a second connection portion 122c and a second device electrode 222c, respectively.
　上記構成を採用することにより、実施の形態１と同様に、ウェア１０２生体センサ装置２０２を装着する場合、装着する向きが１８０度異なっても、同極性の電極同士が接続されるので、電極の極性を誤って装着されることがない。そのため、ウェア１０２から生体センサ装置２０２に送られる心電信号は常に正しい極性となる。 By adopting the above configuration, as in the first embodiment, when the wear 102 biosensor device 202 is mounted, the electrodes of the same polarity are connected to each other even if the mounting direction is 180 degrees different. There is no wrong mounting. Therefore, the electrocardiogram signal sent from the wear 102 to the biosensor device 202 always has the correct polarity.
　なお、図６に示す例では、第１の接続部１１０ｃ、１１０ｄ及び第１の装置電極２１０ｃ、２１０ｄに対して、第２の接続部１２１ｃ及び第２の装置電極２２１ｃが中心０に配置されるが、逆に、第２の接続部及び第２の装置電極に対して第１の接続部及び第１の装置電極を中心０に配置することもできる。 In the example shown in FIG. 6, the second connection portion 121c and the second device electrode 221c are arranged at the center 0 with respect to the first connection portions 110c and 110d and the first device electrodes 210c and 210d. However, conversely, the first connection portion and the first device electrode can be arranged at the center 0 with respect to the second connection portion and the second device electrode.
　また、図６に示す例では、第１の接続部１１０ｃ、１１０ｄ及び第１の装置電極２１０ｃ、２１０ｄは、水平距離Ｂで離間して配置されるが、水平距離Ｂがゼロでもよい。即ち、ウェア１０２の第１の接続部１１０ｃ、１１０ｄと第２の接続部１２２ｃ、及び生体センサ装置２０２の第１の装置電極２１０ｃ、２１０ｄと第２の装置電極２２２ｃは、それぞれ垂直方向に一直線上に配置される。 Further, in the example shown in FIG. 6, the first connection portions 110c and 110d and the first device electrodes 210c and 210d are spaced apart by a horizontal distance B, but the horizontal distance B may be zero. That is, the first connection portions 110c and 110d and the second connection portion 122c of the wear 102, and the first device electrodes 210c and 210d and the second device electrode 222c of the biosensor device 202 are in a straight line, respectively.
