　制御部３０は、マイクロコンピュータで構成されている。制御部３０は、発光部１１のドライブ回路１１ｂにタイミング信号を送信して、第１発光素子１１ａ１および第２発光素子１１ａ２から近赤外光を発するように制御することができる。また、制御部３０は、演算部３１、メモリ３２およびタイマー３３を有する。 The control unit 30 is composed of a microcomputer. The control unit 30 can control to emit near infrared light from the first light emitting element 11a1 and the second light emitting element 11a2 by transmitting a timing signal to the drive circuit 11b of the light emitting unit 11. The control unit 30 includes a calculation unit 31, a memory 32, and a timer 33.
　制御部３０は、内蔵のアナログ－デジタル変換回路を用いて、受光部１２の増幅回路１２ｂから出力された増幅後の受光信号を処理可能なデジタル形式の信号情報に変換する。演算部３１は、この変換された信号情報に基づいて、被検体の血管内を通る血液に関する情報を推定する。 The control unit 30 converts the amplified received light signal output from the amplifier circuit 12b of the light receiving unit 12 into processable digital signal information using a built-in analog-digital conversion circuit. Based on the converted signal information, the calculation unit 31 estimates information related to blood passing through the blood vessel of the subject.
　メモリ３２は、推定した生体関連情報など、各種のデータを記憶する。タイマー３３は、センサモジュール１０の動作時間、すなわち生体関連情報の推定開始からの動作時間を計測する。入出力インタフェース部１４は、センサモジュール１０の外部との情報の入出力を行う。入出力インタフェース部１４には、コネクタや、外部機器（表示装置、記憶装置、ネットワーク）との通信を行う通信手段（無線通信、有線通信）などが含まれる。 The memory 32 stores various data such as estimated biological information. The timer 33 measures the operation time of the sensor module 10, that is, the operation time from the start of estimation of biological related information. The input / output interface unit 14 inputs / outputs information from / to the outside of the sensor module 10. The input / output interface unit 14 includes a connector and communication means (wireless communication, wired communication) for communicating with an external device (display device, storage device, network).
　このような構成を備えたセンサモジュール１０において、例えば、第１近赤外光を用いた計測では、被検体の血管内を通る血液のヘマトクリット（Ｈｃｔ）、血流の拍動、血流量、流速などを得ることができる。また、第１近赤外光および第２近赤外光の両方を用いた計測では、血中ヘモグロビン変化（Ｈｂ変化量）、血中酸素比率変化（酸素度）などを得ることができる。 In the sensor module 10 having such a configuration, for example, in measurement using the first near-infrared light, hematocrit (Hct) of blood passing through the blood vessel of the subject, pulsation of blood flow, blood flow volume, flow velocity Etc. can be obtained. Further, in measurement using both the first near-infrared light and the second near-infrared light, blood hemoglobin change (Hb change amount), blood oxygen ratio change (oxygen level), and the like can be obtained.
　ここで、酸素化ヘモグロビンおよび脱酸素化ヘモグロビンの吸光度は波長８０５ｎｍにおいて等しく、波長８０５ｎｍよりも長波長では酸素化ヘモグロビンの吸光度が脱酸素化ヘモグロビンの吸光度よりも大きく、波長８０５ｎｍよりも短波長では酸素化ヘモグロビンの吸光度が脱酸素化ヘモグロビンの吸光度よりも小さくなる。したがって、波長８０６ｎｍ以上８５５ｎｍ以下の第１近赤外光を含む光、好ましくは第１近赤外光の波長域に発光ピークを有する光を用いることで、酸素化ヘモグロビンを優先的に測定することができる。 Here, the absorbances of oxygenated hemoglobin and deoxygenated hemoglobin are equal at a wavelength of 805 nm, the absorbance of oxygenated hemoglobin is greater than that of deoxygenated hemoglobin at a wavelength longer than 805 nm, and oxygen at a wavelength shorter than 805 nm. The absorbance of oxyhemoglobin is smaller than the absorbance of deoxygenated hemoglobin. Therefore, oxygenated hemoglobin is preferentially measured by using light including first near infrared light having a wavelength of 806 nm or more and 855 nm or less, preferably light having an emission peak in the wavelength range of the first near infrared light. Can do.
　そして、ヘモグロビンの量からヘマトクリット（Ｈｃｔ）を計測できることになる。本実施形態に係るセンサモジュール１０を用いた計測では、ヘマトクリット（Ｈｃｔ）を±１％以下の精度で計測することができる。また、センサモジュール１０では１０ミリ秒程度のサンプリングレートで計測できるため、血液に関する情報を連続的に得ることができる。 And hematocrit (Hct) can be measured from the amount of hemoglobin. In the measurement using the sensor module 10 according to the present embodiment, hematocrit (Hct) can be measured with an accuracy of ± 1% or less. Moreover, since the sensor module 10 can measure at a sampling rate of about 10 milliseconds, information about blood can be obtained continuously.
　また、波長８０５ｎｍよりも短波長の光を含む光により測定を行うと、脱酸素化ヘモグロビンを優先的に測定することができる。そのような光として、波長７５５ｎｍ以上７６５ｎｍ以下（好ましくは７５８ｎｍ以上７６２ｎｍ以下）の第２近赤外光を含む光が例示され、第２近赤外光の波長域に発光ピークを有する光が好ましい光として例示される。そして、第１近赤外光を含む光による測定結果および第２近赤外光を含む光による測定結果から、血中酸素比率変化（酸素度）またはこれに関連する情報を導き出すことが可能である。 Further, when measurement is performed with light including light having a wavelength shorter than 805 nm, deoxygenated hemoglobin can be measured preferentially. Examples of such light include light containing second near infrared light having a wavelength of 755 nm to 765 nm (preferably 758 nm to 762 nm), and light having an emission peak in the wavelength region of the second near infrared light is preferable. Illustrated as light. Then, it is possible to derive blood oxygen ratio change (oxygen level) or related information from the measurement result by the light including the first near infrared light and the measurement result by the light including the second near infrared light. is there.
　例えば、第１近赤外光を用いた計測では、被検体の血管内を通る血液のヘマトクリット（Ｈｃｔ）、血流の拍動、血流量、流速などを得ることができる。また、第１近赤外光および第２近赤外光の両方を用いた計測では、血中ヘモグロビン変化（Ｈｂ変化量）、血中酸素比率変化（酸素度）などを得ることができる。 For example, in the measurement using the first near-infrared light, hematocrit (Hct) of blood passing through the blood vessel of the subject, pulsation of blood flow, blood flow volume, flow velocity, and the like can be obtained. Further, in measurement using both the first near-infrared light and the second near-infrared light, blood hemoglobin change (Hb change amount), blood oxygen ratio change (oxygen level), and the like can be obtained.
　温度測定部４０は、被検体などの温度を測定する。測定した被検体の温度が所定の閾値を超えた場合、制御部３０は発光部１１からの光の放出を停止したり、計測を停止したりする。タイマー３３は、計測開始からの時間（計測時間）をカウントする。タイマー３３によってカウントした計測時間が所定の閾値を超えた場合、制御部３０は計測を停止するなどの処理を行う。 The temperature measuring unit 40 measures the temperature of the subject. When the measured temperature of the subject exceeds a predetermined threshold, the control unit 30 stops emission of light from the light emitting unit 11 or stops measurement. The timer 33 counts the time (measurement time) from the start of measurement. When the measurement time counted by the timer 33 exceeds a predetermined threshold, the control unit 30 performs processing such as stopping the measurement.
　図３（ａ）および（ｂ）は、計測動作を例示する模式断面図である。
　図３（ａ）には押圧前の状態が示され、図３（ｂ）には押圧後の状態が示される。
　図示する例では、生体関連情報計測装置１に指（例えば、人差し指）Ｆを押し当てて計測を行っている。 3A and 3B are schematic cross-sectional views illustrating the measurement operation.
FIG. 3A shows a state before pressing, and FIG. 3B shows a state after pressing.
In the illustrated example, measurement is performed by pressing a finger (for example, index finger) F against the living body related information measuring apparatus 1.
　図３（ａ）に示すように、指Ｆをセンサモジュール１０の受発光面１０ａに軽く接触させた状態では、押圧スイッチ２１０のボタン２１０ａは押し込まれない。ボタン２１０ａが押し込まれないと、動作モードは変化しない。例えば、計測は開始されない。 As shown in FIG. 3A, the button 210a of the push switch 210 is not pushed in a state where the finger F is lightly brought into contact with the light emitting / receiving surface 10a of the sensor module 10. If the button 210a is not depressed, the operation mode does not change. For example, measurement is not started.
　図３（ｂ）に示すように、指Ｆをセンサモジュール１０の受発光面１０ａに所定の力で押圧すると、押圧スイッチ２１０のボタン２１０ａが押し込まれ、センサモジュール１０も筐体５０内に押し込まれる。ボタン２１０ａが押し込まれることで押圧スイッチ２１０が閉状態になり、動作モードが変化する。例えば、センサモジュール１０による計測が開始される。 As illustrated in FIG. 3B, when the finger F is pressed against the light emitting / receiving surface 10 a of the sensor module 10 with a predetermined force, the button 210 a of the pressing switch 210 is pressed and the sensor module 10 is also pressed into the housing 50. . When the button 210a is pushed, the push switch 210 is closed and the operation mode is changed. For example, measurement by the sensor module 10 is started.
　この際、押圧スイッチ２１０のボタン２１０ａの押し込みでクリック感が発生し、このクリック感が指Ｆに伝わる。これにより、被検者は指Ｆに伝わるクリック感によって動作モードが変化したこと（例えば、計測が開始されたこと）を認識することができる。言い換えると、指Ｆにクリック感が伝わらない状態では受発光面１０ａへの指Ｆの押圧力が足りていないことが分かり、被検者はクリック感を得られるまで指Ｆを押し当てることになる。 At this time, a click feeling is generated by pressing the button 210a of the push switch 210, and this click feeling is transmitted to the finger F. Thus, the subject can recognize that the operation mode has changed due to the click feeling transmitted to the finger F (for example, measurement has been started). In other words, in a state where the click feeling is not transmitted to the finger F, it is understood that the pressing force of the finger F on the light emitting / receiving surface 10a is insufficient, and the subject presses the finger F until the click feeling is obtained. .
　クリック感を得られる押圧力は押圧スイッチ２１０によって決定される。この押圧力は、指Ｆの腹と受発光面１０ａとの密着力が計測に適した力となっている。これにより、クリック感を得られるまで指Ｆを押し付けると、指Ｆと受発光面１０ａとが計測に適した状態で密着し、受光部１２で取り込んだ光から高精度に生体関連情報を推定することができるようになる。 The pressing force that can provide a click feeling is determined by the pressing switch 210. In this pressing force, the adhesion force between the belly of the finger F and the light emitting / receiving surface 10a is a force suitable for measurement. Thus, when the finger F is pressed until a click feeling is obtained, the finger F and the light emitting / receiving surface 10a come into close contact with each other in a state suitable for measurement, and biological information is estimated with high accuracy from the light captured by the light receiving unit 12. Will be able to.
　図４は、押圧前後による計測脈拍の例を示す図である。
　図４における横軸は時間であり、縦軸は心拍の振れ値である。時間０から時間ｔ１までは指Ｆを受発光面１０ａに押圧せず接触させている状態である。この状態では脈波を正確に計測できていない。 FIG. 4 is a diagram illustrating an example of measurement pulses before and after pressing.
The horizontal axis in FIG. 4 is time, and the vertical axis is the heartbeat fluctuation value. From time 0 to time t1, the finger F is in contact with the light emitting / receiving surface 10a without being pressed. In this state, the pulse wave cannot be measured accurately.
　時間ｔ１から時間ｔ２までの間では、指Ｆを受発光面１０ａに所定の押圧力で押し付けている。この状態では脈波を正確に計測できていることが分かる。時間ｔ２を過ぎたところで指Ｆの押圧力を再び緩めている。この状態では脈波を正確に計測できていない。 During the period from time t1 to time t2, the finger F is pressed against the light emitting / receiving surface 10a with a predetermined pressing force. It can be seen that the pulse wave can be accurately measured in this state. When the time t2 has passed, the pressing force of the finger F is loosened again. In this state, the pulse wave cannot be measured accurately.
　このように、指Ｆを受発光面１０ａに所定の押圧力で押し付けることで精度良く安定した計測を行うことができる。本実施形態に係る生体関連情報計測装置１では、精度良く安定して計測できる押圧力になると押圧スイッチ２１０のボタン２１０ａが押し込まれ、クリック感を発生させる。したがって、被検者は、指Ｆに伝わるクリック感によって精度良く安定して計測できる押圧力になったことを認識することができる。生体関連情報計測装置１では、クリック感によって被検者に計測に適した押圧力になっていることを通知することで、生体関連情報を精度良く安定して計測できることになる。 Thus, accurate and stable measurement can be performed by pressing the finger F against the light emitting / receiving surface 10a with a predetermined pressing force. In the living body related information measuring apparatus 1 according to the present embodiment, when a pressing force that can be measured stably with high accuracy is reached, the button 210a of the pressing switch 210 is pressed to generate a click feeling. Therefore, the subject can recognize that the pressing force that can be measured accurately and stably by the click feeling transmitted to the finger F is obtained. In the living body related information measuring apparatus 1, the living body related information can be accurately and stably measured by notifying the subject that the pressing force is suitable for the measurement by the click feeling.
　また、例えば、指先が冷えた状態（虚脈）では脈波が弱いため、血圧を推定する演算の正確性が不十分となる。このような指先が冷えた状態であっても指先を受発光面１０ａに押圧してある程度の圧力を加えることで、生体関連情報計測装置１による脈波計測精度が高まり、推定血圧の演算の正確性を高めることができる。したがって、本実施形態のように押圧スイッチ２１０によって指Ｆで押圧した際のクリック感を被検者に与えることで、虚脈状態であっても正確な計測を行うことができる状態を被検者に認識させることができる。これにより、生体関連情報計測装置１では精度良く安定した計測を行うことが可能となる。 Also, for example, in a state where the fingertip is cold (i.e., an imaginary pulse), the pulse wave is weak, so that the accuracy of the calculation for estimating the blood pressure is insufficient. Even when the fingertip is in a cold state, by applying a certain amount of pressure by pressing the fingertip against the light emitting / receiving surface 10a, the pulse wave measurement accuracy by the living body related information measuring device 1 is increased, and the calculation of the estimated blood pressure is accurate. Can increase the sex. Therefore, by giving the subject a click feeling when the finger F is pressed by the pressing switch 210 as in the present embodiment, the subject can be in a state in which accurate measurement can be performed even in the venous state. Can be recognized. As a result, the living body related information measuring apparatus 1 can perform accurate and stable measurement.
（第２実施形態）
　図５（ａ）および（ｂ）は、第２実施形態に係る生体関連情報計測装置を例示する模式図である。
　図５（ａ）には本実施形態に係る生体関連情報計測装置１Ｂの断面図が示され、図５（ｂ）には生体関連情報計測装置１Ｂの使用状態の断面図が示される。 (Second Embodiment)
FIGS. 5A and 5B are schematic views illustrating a living body related information measuring device according to the second embodiment.
FIG. 5A shows a cross-sectional view of the living body related information measuring apparatus 1B according to the present embodiment, and FIG. 5B shows a cross-sectional view of the living body related information measuring apparatus 1B in use.
　本実施形態に係る生体関連情報計測装置１Ｂは、筐体５０におけるセンサモジュール１０の受発光面１０ａとは反対側（底側）にラバー５５が設けられている。すなわち、筐体５０の底がラバー５５になっており、ラバー５５の部分を外側から押すことで、筐体５０内部の押圧スイッチ２１０のボタン２１０ａを押せるようになっている。 In the living body related information measuring apparatus 1B according to the present embodiment, a rubber 55 is provided on the side (bottom side) opposite to the light emitting / receiving surface 10a of the sensor module 10 in the housing 50. That is, the bottom of the casing 50 is a rubber 55, and the button 210a of the push switch 210 inside the casing 50 can be pressed by pressing the rubber 55 portion from the outside.
　この生体関連情報計測装置１Ｂでは、例えば被検体Ｓの皮膚（限定されない具体例として手首の皮膚が挙げられる。）に受発光面１０ａを密着させておき、計測を行う際に指Ｆでラバー５５の部分を押すようにする。ラバー５５の部分を押すことで、押圧スイッチ２１０のボタン２１０ａが押し込まれる。 In the living body related information measuring apparatus 1B, for example, the light receiving / emitting surface 10a is brought into close contact with the skin of the subject S (specifically, skin of the wrist is not limited), and the rubber 55 is used with the finger F when performing measurement. Press the part. By pushing the rubber 55 portion, the button 210a of the push switch 210 is pushed.
　指Ｆによる押圧力が所定の大きさを超えると、押圧スイッチ２１０からクリック感が発生する。クリック感は指Ｆに伝わり、被検者に所定の押圧力で押されたことを認識させることができる。クリック感が発生する押圧力以上でラバー５５を押さえると、被検体Ｓの皮膚と受発光面１０ａとが、計測に適した力で密着する状態になる。 When the pressing force by the finger F exceeds a predetermined magnitude, a click feeling is generated from the pressing switch 210. The click feeling is transmitted to the finger F, and the subject can recognize that the subject has been pressed with a predetermined pressing force. When the rubber 55 is pressed with a pressing force that generates a click feeling, the skin of the subject S and the light emitting / receiving surface 10a come into close contact with a force suitable for measurement.
　そして、ボタン２１０ａが押し込まれることで押圧スイッチ２１０が閉状態になり、センサモジュール１０による計測が開始される。この状態で計測することで、生体関連情報計測装置１Ｂは、被検体Ｓの皮膚と受発光面１０ａとを計測に適した押圧力のもとで計測することができ、生体関連情報を精度良く安定して計測できることになる。また、被検者は、指Ｆに伝わるクリック感によって、計測に適した押圧力で押していることを認識することができる。 Then, when the button 210a is pushed, the push switch 210 is closed, and measurement by the sensor module 10 is started. By measuring in this state, the living body-related information measuring apparatus 1B can measure the skin of the subject S and the light emitting / receiving surface 10a under a pressing force suitable for measurement, and the living body related information can be accurately obtained. It will be possible to measure stably. In addition, the subject can recognize that the subject is pressing with a pressing force suitable for measurement by the click feeling transmitted to the finger F.
（第３実施形態）
　図６（ａ）～（ｃ）は、第３実施形態に係る生体関連情報計測装置を例示する模式図である。
　図６（ａ）に示すように、本実施形態に係る生体関連情報計測装置１Ｃは、基板１００の裏面側に、通知部２０の一つである第１押圧スイッチ２１１と、通知部２０の他の一つである第２押圧スイッチ２１２とが設けられている。第１押圧スイッチ２１１と第２押圧スイッチ２１２とは、それぞれのボタン２１１ａ、２１２ａが押し込まれた際のクリック感の発生タイミングが異なっている。 (Third embodiment)
6A to 6C are schematic views illustrating a living body related information measuring apparatus according to the third embodiment.
As illustrated in FIG. 6A, the living body related information measuring apparatus 1 </ b> C according to the present embodiment includes a first press switch 211 that is one of the notification units 20 and the notification unit 20 on the back side of the substrate 100. And a second push switch 212 which is one of the above. The first push switch 211 and the second push switch 212 are different in the click generation timing when the respective buttons 211a and 212a are pushed.
　第１押圧スイッチ２１１は、第２押圧スイッチ２１２よりも弱い押圧力によってクリック感が発生する。第２押圧スイッチ２１２は、第１押圧スイッチ２１１よりも強い押圧力でクリック感が発生する。 The first pressing switch 211 generates a click feeling with a pressing force weaker than that of the second pressing switch 212. The second pressing switch 212 generates a click feeling with a pressing force stronger than that of the first pressing switch 211.
　図６（ａ）に示すように、指Ｆを受発光面１０ａに軽く接触させた状態では、第１押圧スイッチ２１１のボタン２１１ａおよび第２押圧スイッチ２１２のボタン２１２ａのいずれも押されず、クリック感は発生しない。 As shown in FIG. 6A, when the finger F is in light contact with the light emitting / receiving surface 10a, neither the button 211a of the first pressing switch 211 nor the button 212a of the second pressing switch 212 is pressed. Does not occur.
　図６（ｂ）に示すように、指Ｆで受発光面１０ａを僅かに押圧すると、第１押圧スイッチ２１１のボタン２１１ａが押され、第１押圧スイッチ２１１からクリック感が発生する。この押圧力では第２押圧スイッチ２１２のボタン２１２ａは押されない。 As shown in FIG. 6B, when the light receiving / emitting surface 10a is slightly pressed with the finger F, the button 211a of the first pressing switch 211 is pressed, and a click feeling is generated from the first pressing switch 211. With this pressing force, the button 212a of the second pressing switch 212 is not pressed.
　図６（ｃ）に示すように、指Ｆでさらに強く受発光面１０ａを押圧すると、第２押圧スイッチ２１２のボタン２１２ａが押され、第２押圧スイッチ２１２からクリック感が発生する。つまり、本実施形態に係る生体関連情報計測装置１Ｃでは、指Ｆによる押圧力に応じて２段階のクリック感を得ることができる。 As shown in FIG. 6C, when the light receiving / emitting surface 10 a is pressed more strongly with the finger F, the button 212 a of the second pressing switch 212 is pressed, and a click feeling is generated from the second pressing switch 212. That is, in the living body related information measuring apparatus 1C according to the present embodiment, a two-step click feeling can be obtained according to the pressing force by the finger F.
　２段階のクリック感を利用する一例として、先ず、第１押圧スイッチ２１１のボタン２１１ａが押され１段目のクリック感を発生させた段階で、センサモジュール１０の計測におけるキャリブレーションを行う。次に、第２押圧スイッチ２１２のボタン２１２ａが押され２段目のクリック感を発生させた段階で、センサモジュール１０による計測を開始する。これにより、被検者は２段階のクリック感によってキャリブレーションから計測に至る一連の流れを認識することができ、生体関連情報計測装置１Ｃによって精度良く安定した計測を行うことができるようになる。 As an example of using the two-step click feeling, first, calibration is performed in the measurement of the sensor module 10 when the button 211a of the first push switch 211 is pressed to generate the first-step click feeling. Next, measurement by the sensor module 10 is started when the button 212a of the second pressing switch 212 is pressed to generate a second click feeling. Accordingly, the subject can recognize a series of flow from calibration to measurement by a two-step click feeling, and can perform stable measurement with high accuracy by the biological related information measuring apparatus 1C.

　図８は、生体関連情報計測装置の構成を例示するブロック図である。
　本実施形態に係る生体関連情報計測装置１Ｄは、受発光部１５と、通知部２０とを備えている。すなわち、生体関連情報計測装置１Ｄにおいては、筐体５０に設けられたセンサモジュール１０に受発光部１５および通知部２０が設けられている。制御部３０は筐体５０の内部ではなく、外部に設けられる。例えば、制御部３０は、外部の表示部８０に設けられる。表示部８０にはバッテリー６０が設けられていてもよい。生体関連情報計測装置１Ｄと外部の制御部３０とによって生体関連情報計測システム１Ｓが構成される。なお、生体関連情報計測システム１Ｓを生体関連情報計測装置と呼んでもよい。 (Fourth embodiment)
FIG. 7 is a schematic view illustrating a living body-related information measuring device according to the fourth embodiment.
FIG. 8 is a block diagram illustrating the configuration of the living body related information measuring apparatus.
The living body related information measuring apparatus 1D according to the present embodiment includes a light emitting / receiving unit 15 and a notification unit 20. That is, in the living body related information measuring apparatus 1 </ b> D, the light emitting / receiving unit 15 and the notification unit 20 are provided in the sensor module 10 provided in the housing 50. The control unit 30 is provided not outside the housing 50 but outside. For example, the control unit 30 is provided in the external display unit 80. The display unit 80 may be provided with a battery 60. The living body related information measuring system 1S is configured by the living body related information measuring device 1D and the external control unit 30. The biological related information measuring system 1S may be called a biological related information measuring device.
　図８に示すように、センサモジュール１０には制御部３０およびバッテリー６０は設けられていない。センサモジュール１０には、受発光部１５、ドライブ回路１１ｂ、増幅回路１２ｂおよび温度測定部４０が含まれ、このセンサモジュール１０が筐体５０に組み込まれて生体関連情報計測装置１Ｄを構成している。 As shown in FIG. 8, the sensor module 10 is not provided with the control unit 30 and the battery 60. The sensor module 10 includes a light emitting / receiving unit 15, a drive circuit 11 b, an amplifier circuit 12 b, and a temperature measuring unit 40, and the sensor module 10 is incorporated in a housing 50 to constitute a living body related information measuring device 1 </ b> D. .
　生体関連情報計測装置１Ｄは、ケーブルＣによって表示部８０と接続される。このケーブルＣによって制御部３０と生体関連情報計測装置１Ｄとの間の情報の送受信や、バッテリー６０による電力供給が行われる。 The living body related information measuring apparatus 1D is connected to the display unit 80 by the cable C. Transmission and reception of information between the control unit 30 and the living body related information measuring apparatus 1D and power supply by the battery 60 are performed by the cable C.
　筐体５０には手Ｈの指Ｆ（例えば、人差し指）を置くことができる凹部５１が設けられている。センサモジュール１０はこの凹部５１の指Ｆの先が当たる位置に配置される。つまり、凹部５１の指Ｆの先が当たる位置に受発光面１０ａが露出している。受発光面１０ａの下方（基板１００の裏面側）には通知部２０としての押圧スイッチ２１０が設けられる。 The housing 50 is provided with a recess 51 in which a finger F of the hand H (for example, an index finger) can be placed. The sensor module 10 is arranged at a position where the tip of the finger F of the recess 51 hits. That is, the light emitting / receiving surface 10a is exposed at the position where the tip of the finger F of the recess 51 hits. A push switch 210 as the notification unit 20 is provided below the light emitting / receiving surface 10a (the back side of the substrate 100).
　このような構成により、被検者は手Ｈの指Ｆを筐体５０の凹部５１に置いて、指Ｆの腹を受発光面１０ａに押し付ける。この押し付け力によって押圧スイッチ２１０が押され、所定の押圧力を超えた段階で押圧スイッチ２１０からクリック感が発生する。クリック感の発生によって被検者は計測が開始されたことを認識する。 With such a configuration, the subject places the finger F of the hand H in the recess 51 of the housing 50 and presses the belly of the finger F against the light emitting / receiving surface 10a. The pressing switch 210 is pressed by this pressing force, and a click feeling is generated from the pressing switch 210 when a predetermined pressing force is exceeded. The subject recognizes that the measurement has been started by the occurrence of the click feeling.
　センサモジュール１０は、押圧スイッチ２１０が押されたタイミングで計測を開始する。そして、制御部３０で演算を行い、計測結果や推定結果を表示部８０に表示する。計測が終わったら、被検者は指Ｆを筐体５０の凹部５１から離す。 The sensor module 10 starts measurement at the timing when the pressing switch 210 is pressed. Then, calculation is performed by the control unit 30, and measurement results and estimation results are displayed on the display unit 80. When the measurement is completed, the subject removes the finger F from the recess 51 of the housing 50.
　このように、制御部３０やバッテリー６０を外部に設けた生体関連情報計測装置１Ｄを用いることで、生体関連情報計測装置１Ｄを軽量かつコンパクトにすることができる。また、生体関連情報計測装置１Ｄを表示部８０から離して、被検者による計測を行いやすい位置に生体関連情報計測装置１Ｄを配置することができる。このような生体関連情報計測装置１Ｄを用いることで、利用形態の幅を拡げることが可能となる。 Thus, by using the living body related information measuring apparatus 1D provided with the control unit 30 and the battery 60 outside, the living body related information measuring apparatus 1D can be made light and compact. In addition, the living body related information measuring device 1D can be placed away from the display unit 80, and the living body related information measuring device 1D can be arranged at a position where the measurement by the subject is easy.

（その他の態様）
　図１１および図１２は、その他の態様を説明する模式図である。
　図１１（ａ）および（ｂ）に示す態様は、センサモジュール１０の周囲に通知部２０としての弾性部材５７を設けた構成である。センサモジュール１０は基板１４０の上に実装されており、このセンサモジュール１０の回りを囲むように弾性部材５７が設けられている。弾性部材５７は、例えばシリコーンゴムによって形成されている。弾性部材５７の中央部分には孔５７ｈが設けられており、孔５７ｈを介して受発光部１５での発光および受光を行えるようになっている。 (Other aspects)
11 and 12 are schematic diagrams for explaining other aspects.
The mode shown in FIGS. 11A and 11B is a configuration in which an elastic member 57 as the notification unit 20 is provided around the sensor module 10. The sensor module 10 is mounted on the substrate 140, and an elastic member 57 is provided so as to surround the sensor module 10. The elastic member 57 is made of, for example, silicone rubber. A hole 57h is provided in the central portion of the elastic member 57, and light emission and light reception by the light emitting / receiving unit 15 can be performed through the hole 57h.
　図１１（ａ）に示すように、弾性部材５７に圧力を加えない状態では、弾性部材５７は凸型になっている。一方、図１１（ｂ）に示すように、指Ｆによって弾性部材５７を押圧すると、所定の圧力を超えた段階で弾性部材５７の凸型の一部がクリック感とともに凹む状態になる。 As shown in FIG. 11A, in a state where no pressure is applied to the elastic member 57, the elastic member 57 is convex. On the other hand, as shown in FIG. 11B, when the elastic member 57 is pressed by the finger F, a part of the convex shape of the elastic member 57 is recessed with a click feeling when the predetermined pressure is exceeded.
　弾性部材５７が凹むことで指Ｆの腹と受発光面１０ａとの密着力が計測に適した力となる。これにより、クリック感が得られるまで指Ｆで弾性部材５７を押し込むことで、指Ｆと受発光面１０ａとが計測に適した状態で密着し、受光部１２で取り込んだ光から高精度に生体関連情報を推定することができるようになる。 Since the elastic member 57 is recessed, the adhesion force between the belly of the finger F and the light emitting / receiving surface 10a becomes a force suitable for measurement. Thus, by pressing the elastic member 57 with the finger F until a click feeling is obtained, the finger F and the light emitting / receiving surface 10a are in close contact with each other in a state suitable for measurement, and the living body is accurately obtained from the light captured by the light receiving unit 12. Related information can be estimated.
　図１２（ｂ）に示す態様は、屈曲可能な基材としてフレキシブルケーブル１５０を用いた構成である。フレキシブルケーブル１５０の一方の面にセンサモジュール１０と押圧スイッチ２１０とを並置しておき、フレキシブルケーブル１５０のセンサモジュール１０と押圧スイッチ２１０との間を折り曲げる。この折り曲げによってセンサモジュール１０と押圧スイッチ２１０とを背合わせにする。これにより、センサモジュール１０の受発光面１０ａとは反対側に押圧スイッチ２１０が位置する構造を容易に形成することができる。 The mode shown in FIG. 12B is a configuration using a flexible cable 150 as a bendable base material. The sensor module 10 and the pressing switch 210 are juxtaposed on one surface of the flexible cable 150, and the space between the sensor module 10 and the pressing switch 210 of the flexible cable 150 is bent. By this bending, the sensor module 10 and the pressing switch 210 are back to back. Thereby, the structure where the press switch 210 is located on the opposite side to the light emitting / receiving surface 10a of the sensor module 10 can be easily formed.
（他の物理的作用）
　上記説明した通知部２０は、指Ｆなどの被検体Ｓにクリック感を与える構成であるが、クリック感以外の物理的作用を与えてもよい。例えば、通知部２０は、被検体Ｓに振動を与える振動部を有していてもよい。振動部は、センサモジュール１０の受発光面１０ａに所定の閾値を超える押圧力が加えられた際に被検体Ｓに振動を与えてもよいし、所定の閾値を超える押圧力が加えられている間、被検体Ｓに連続して振動を与えるようにしてもよい。 (Other physical effects)
The notification unit 20 described above is configured to give a click feeling to the subject S such as the finger F, but may provide a physical action other than the click feeling. For example, the notification unit 20 may include a vibration unit that applies vibration to the subject S. The vibration unit may apply vibration to the subject S when a pressing force exceeding a predetermined threshold is applied to the light receiving and emitting surface 10a of the sensor module 10, or a pressing force exceeding the predetermined threshold is applied. During this time, the subject S may be continuously vibrated.
　また、通知部２０は、被検体Ｓに物理的作用を加えるとともに、音および光の少なくともいずれかを出力するようにしてもよい。これにより、センサモジュール１０の受発光面１０ａに所定の閾値を超える押圧力が加えられ、被検体Ｓに物理的作用を加える場合に、音および光の少なくともいずれかによって利用者に計測における所定の段階を認識させることができる。 Further, the notification unit 20 may apply a physical action to the subject S and output at least one of sound and light. Thereby, when a pressing force exceeding a predetermined threshold is applied to the light receiving / emitting surface 10a of the sensor module 10 and a physical action is applied to the subject S, a predetermined measurement in the user is performed by at least one of sound and light. The stage can be recognized.
　例えば、受発光面１０ａに所定の閾値を超える押圧力が加えられている間、音や光の少なくともいずれかを連続して出力し、押圧力が所定の閾値以下になった場合には、音や光の少なくとものいずれかの出力を停止する。利用者はクリック感などの物理的作用によって所定の閾値を超える押圧力で押していることを認識でき、この状態が継続していることを音や光の少なくともいずれかで認識することができる。また、音や光の少なくともいずれかの出力が停止すると、利用者は押圧力が足りていないことを認識することができる。 For example, while a pressing force exceeding a predetermined threshold is being applied to the light emitting / receiving surface 10a, at least one of sound and light is continuously output, and when the pressing force falls below a predetermined threshold, Or stop the output of at least one of the light. The user can recognize that the user is pressing with a pressing force exceeding a predetermined threshold by a physical action such as a click feeling, and can recognize that this state is continuing with at least one of sound and light. Further, when the output of at least one of sound and light stops, the user can recognize that the pressing force is insufficient.
　また、通知部２０は、被検体Ｓと受発光部１５との間の圧力が所定の閾値を超えた段階でパルス的な物理的作用（例えば、クリック感）を被検体Ｓに加えるようにしてもよいし、被検体Ｓと受発光部１５との間の圧力が所定の閾値を超えている間、継続的に物理的作用（例えば、振動、音、光）を与えるようにしてもよい。また、通知部２０は、被検体Ｓと受発光部１５との間の圧力が所定の閾値以下になった際に被検体Ｓに物理的作用を加えるようにしてもよい。 Further, the notification unit 20 applies a pulsed physical action (for example, a click feeling) to the subject S when the pressure between the subject S and the light emitting / receiving unit 15 exceeds a predetermined threshold. Alternatively, a physical action (for example, vibration, sound, light) may be continuously applied while the pressure between the subject S and the light receiving and emitting unit 15 exceeds a predetermined threshold. In addition, the notification unit 20 may apply a physical action to the subject S when the pressure between the subject S and the light emitting / receiving unit 15 becomes a predetermined threshold value or less.
　被検体Ｓと受発光部１５との間の圧力が所定の閾値を超えたか否かによる光の出力変化としては、光の点灯、点滅、発光色の変化が挙げられる。例えば、物理的作用を加える前後で光の点灯、消灯の切り替え、光の点灯、点滅の切り替え、発光色の切り替えを行うようにしてもよい。また、被検体Ｓと受発光部１５との間の圧力が所定の閾値を超えたか否かによる音の出力変化としては、連続音の出力、停止の切り替え、連続音と断続音との切り替え、音の周波数の切り替えを行うようにしてもよい。 The light output change depending on whether or not the pressure between the subject S and the light emitting / receiving unit 15 exceeds a predetermined threshold includes lighting of light, blinking, and change in emission color. For example, before and after applying a physical action, switching on / off of light, switching on / off of light, and switching of emission color may be performed. Further, as the output change of the sound depending on whether or not the pressure between the subject S and the light emitting / receiving unit 15 exceeds a predetermined threshold, the output of the continuous sound, switching of the stop, switching between the continuous sound and the intermittent sound, The sound frequency may be switched.
（動作モードの切り替え）
　本実施形態に係る生体関連情報計測装置１、１Ｂ、１Ｃおよび１Ｄでは、通知部２０によって被検体に物理的作用を加えることで、利用者に動作モードの切り替わりを認識させることができる。すなわち、制御部３０は、通知部２０によって被検体Ｓに物理的作用を加えている状態と、加えていない状態とで動作モードを変える制御を行う。例えば、通知部２０から被検体Ｓに物理的作用が加えられた段階で、受発光部１５での計測を開始するように制御してもよいし、キャリブレーションを開始するように制御してもよい。 (Switching operation mode)
In the living body related information measuring apparatuses 1, 1B, 1C, and 1D according to the present embodiment, the user can be made to recognize the switching of the operation mode by applying a physical action to the subject by the notification unit 20. That is, the control unit 30 performs control to change the operation mode between a state in which a physical action is applied to the subject S by the notification unit 20 and a state in which the physical action is not applied. For example, when a physical action is applied to the subject S from the notification unit 20, the measurement may be started by the light emitting / receiving unit 15, or the calibration may be started. Good.
　また、制御部３０は、通知部２０から被検体Ｓに物理的作用が加えられた段階で、演算部３１で生体関連情報を推定するよう制御を行ってもよい。この場合、予め受発光部１５での発光および受光の動作を行っておき、被検体Ｓが受発光面１０ａに接触して所定の押圧力に達した段階で通知部２０から被検体に物理的作用を加える。そして、この段階から演算部３１による推定処理を開始する。これにより、物理的作用によって利用者に生体関連情報の推定開始を認識させることができる。 In addition, the control unit 30 may perform control so that the calculation unit 31 estimates biological related information at the stage when a physical action is applied to the subject S from the notification unit 20. In this case, the light emitting and receiving operations in the light emitting / receiving unit 15 are performed in advance, and when the subject S comes into contact with the light emitting / receiving surface 10a and reaches a predetermined pressing force, the notification unit 20 physically applies the subject to the subject. Add action. And the estimation process by the calculating part 31 is started from this stage. Thereby, a user can be made to recognize the estimation start of biological body relevant information by a physical effect | action.
　以上説明したように、本実施形態によれば、計測に適した押圧力で被検体Ｓと受発光面１０ａとが接触していることを利用者に認識させることができ、精度の高い計測を行うことができるようになる。 As described above, according to the present embodiment, it is possible to make the user recognize that the subject S and the light emitting / receiving surface 10a are in contact with each other with a pressing force suitable for measurement, and perform highly accurate measurement. Will be able to do.
　なお、上記に本実施形態を説明したが、本発明はこれらの例に限定されるものではない。例えば、前述の説明では被検体Ｓとして指Ｆの例を示したが、指Ｆ以外の部位（例えば、手首、腕、足首、胴、首、頭）であってもよい。また、前述の実施形態に対して、当業者が適宜、構成要素の追加、削除、設計変更を行ったものや、各実施形態の特徴を適宜組み合わせたものも、本発明の要旨を備えている限り、本発明の範囲に包含される。 Although the present embodiment has been described above, the present invention is not limited to these examples. For example, although the example of the finger F as the subject S has been described in the above description, it may be a part other than the finger F (for example, wrist, arm, ankle, torso, neck, head). Further, those in which those skilled in the art appropriately added, deleted, and changed the design of the above-described embodiments, and combinations of the features of each embodiment as appropriate also have the gist of the present invention.
