  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a functional block diagram showing a schematic configuration of a measuring apparatus according to an embodiment of the present invention. The measurement apparatus 10 includes an authentication sensor 11, a proximity sensor 12, a biosensor 13, a contact unit 14, a storage unit 15, a control unit 16, and a biometric information generation unit 17.

  The measuring device 10 measures biological information in a region to be examined that contacts the contact unit 14. FIG. 2 is a diagram illustrating an example of a usage state of the measurement device 10, and is a diagram illustrating a state in which a user presses a finger of a hand that is a test site against the measurement device 10. The measuring apparatus 10 can be mounted on various electronic devices. FIG. 2 is a diagram showing an example of a mobile phone equipped with the measuring apparatus 10 of FIG. As shown in FIG. 2A, the mobile phone 30 includes a measuring device 10 on the back side thereof. The measurement apparatus 10 measures biological information in a state where the finger is pressed against the contact portion 14 as shown in FIG. The biological information can be any biological information that can be measured using the biological sensor 13. In the present embodiment, the measurement device 10 will be described below as an example of measuring the blood flow of a subject, which is information related to blood flow.

  In FIG. 1, the authentication sensor 11 acquires authentication information for authenticating a subject from a test site that contacts the contact unit 14. The authentication information is information related to the living body of the subject, and is, for example, a vein pattern at the subject site of the subject. In the present embodiment, the authentication information is described as information related to the vein pattern. However, the authentication information is not limited to information related to the vein pattern. For example, the authentication information of the subject who authenticates the subject such as a fingerprint is used. It can be any information related to the living body.

  When the authentication information is information related to the vein pattern, the authentication sensor 11 includes an authentication sensor light source 23 and an imaging unit 24.

  The authentication sensor light source 23 irradiates the test site with near infrared light based on the control of the control unit 16. The authentication sensor light source 23 irradiates, for example, a near-infrared light having a wavelength capable of detecting a predetermined component (for example, reduced hemoglobin in red blood cells) flowing in a vein. : Light Emitting Diode).

  The imaging unit 24 images the vein pattern of the test site based on the scattered light from the test site of the near infrared light irradiated by the authentication sensor light source 23. The imaging unit 24 is configured by, for example, a CCD camera. Near-infrared light irradiated to the test site by the authentication sensor light source 23 is absorbed by reduced hemoglobin in the blood flowing in the vein, so that the vein pattern appears dark in the image captured by the imaging unit 24. In this way, the authentication sensor 11 can acquire authentication information.

  The proximity sensor 12 acquires contact information regarding the contact state between the test site and the contact portion 14. The proximity sensor 12 includes a proximity sensor light source 25 and a proximity sensor light receiving unit 26.

  The proximity sensor light source 25 irradiates an object close to the contact unit 14 with infrared light based on the control of the control unit 16. The proximity sensor light source 25 is configured by, for example, an LED that irradiates a test site with infrared light.

  The proximity sensor light receiving unit 26 receives the scattered light of the infrared light emitted from the proximity sensor light source 25 from the test site. For example, based on the intensity of scattered light received by the proximity sensor light receiving unit 26, that is, contact information regarding the contact state between the test site and the contact unit 14, the control unit 16 contacts the test site and the contact unit 14. To determine if they are touching or not touching.

  The biosensor 13 acquires a biometric output from the test site. When the measuring apparatus 10 measures the blood flow volume as in the present embodiment, the biosensor 13 includes a biosensor light source 21 and a biosensor light receiving unit 22.

  The biosensor light source 21 emits laser light based on the control of the control unit 16. The biosensor light source 21 irradiates, for example, a laser beam having a wavelength capable of detecting a predetermined component contained in blood as measurement light to a test site, and is configured by, for example, an LD (Laser Diode). The

  The biosensor light receiving unit 22 receives the scattered light of the measurement light from the test site as a biometric output. The biosensor light receiving unit 22 is configured by, for example, a PD (Photo Diode). The biosensor 13 transmits the photoelectric conversion signal of the scattered light received by the biosensor light receiving unit 22 to the control unit 16.

  The contact part 14 is a part that contacts a test site such as a finger in order for the subject to measure biological information. The contact part 14 is comprised by the plate-shaped member, for example. The contact unit 14 includes at least near-infrared light from the authentication sensor light source 23, infrared light from the proximity sensor light source 25, measurement light from the biosensor light source 21, and near-infrared light, infrared light, and measurement light. A member transparent to scattered light from the test site is used.

  The storage unit 15 can be configured by a semiconductor memory, a magnetic memory, or the like, and stores various information, a program for operating the measurement apparatus 10, and the like, and also functions as a work memory.

  The storage unit 15 stores identification information relating to the living body of the subject that can identify the subject in association with the subject. The specific information is collated with the authentication information acquired by the authentication sensor 11 by the control unit 16 and is information corresponding to the authentication information. Therefore, in the present embodiment, the specific information is a vein pattern at the subject site of the subject. The storage unit 15 may store a plurality of specific information in association with each subject.

  The subject performs an operation of registering specific information in the storage unit 15 in advance when measuring biological information using the measuring device 10. For example, the registration is performed by bringing the test site into contact with the contact portion 14 after setting the measurement device 10 in a state where the specific information can be registered by operating an input unit included in the measurement device 10. At this time, the control unit 16 of the measuring apparatus 10 emits near-infrared light from the authentication sensor 11, and the imaging unit 24 images the vein pattern of the test site. The control unit 16 stores the captured vein pattern in the storage unit 15 in association with the subject.

  The storage unit 15 may store the biological information measured by the measurement device 10 in association with the subject. The storage unit 15 stores the biological information accumulated for each subject in this way as a history.

  The control unit 16 is a processor that controls and manages the entire measurement apparatus 10 including each functional block of the measurement apparatus 10. The control unit 16 includes a processor such as a CPU (Central Processing Unit) that executes a program that defines a control procedure, and the program is stored in, for example, the storage unit 15 or an external storage medium.

  The control unit 16 controls the measurement light emitted from the biosensor light source 21 based on the authentication information acquired by the authentication sensor 11 when the subject measures the biometric information using the measurement device 10. Specifically, when the control unit 16 determines that the authentication information acquired by the authentication sensor 11 matches any of the specific information stored in the storage unit 15, the laser light as the measurement light from the biosensor light source 21. Inject. In this way, the control unit 16 starts obtaining the biometric output from the biosensor 13. If the authentication information does not match the specific information, even if the registered subject is using the measuring device 10, the unregistered part is in contact with the contact part 14 or the registered subject Even if it is a test site | part, it will be contacting the contact part 14 in the state shifted | deviated from the registered state. Therefore, in this way, the control unit 16 starts obtaining biometric measurement output when the authentication information matches the specific information, so that every time biometric information is measured, the biometric information is obtained at the same test site. It can be measured. Therefore, since the error of the measurement condition of biological information can be reduced, the reliability of biological information can be improved. Since the vein pattern is unique information for each subject, it is difficult to be erroneously authenticated, and since it is information inside the body of the subject, it is difficult to forge. Furthermore, since the vein pattern is not easily affected by external changes such as aging and injury, the subject can use the measuring device 10 without updating the registered specific information for a long time.

  When it is determined that the authentication information acquired by the authentication sensor 11 does not match any of the specific information stored in the storage unit 15, the control unit 16 does not emit laser light from the biosensor light source 21. In this case, the control unit 16 may notify the error information from the notification unit 18 included in the measurement apparatus 10. The error information is, for example, information for notifying that biometric information cannot be measured or that the authentication information does not match the specific information. The error information may include, for example, a notification instructing to move the position of the test site that contacts the contact unit 14.

  The alerting | reporting part 18 can alert | report by the visual method by an image, a character, light emission, etc., the auditory methods, such as an audio | voice, or those combinations, for example. When the notification unit 18 performs notification by a visual method, for example, the notification unit 18 performs notification by displaying an image or a character as a display device. For example, the notification unit 18 may perform notification by causing a light emitting element such as an LED to emit light. When notifying by an auditory method, the notification unit 18 performs notification by outputting an alarm sound, a voice guide, or the like as a sound generating device such as a speaker. The notification performed by the notification unit 18 is not limited to a visual or auditory method, and may be any method that can be recognized by the subject. When the measuring apparatus 10 is mounted on the mobile phone 30 as in the present embodiment, the control unit 16 may use the notification function unit of the mobile phone 30 as the notification unit 18.

  The control unit 16 controls the biosensor light source 21 based on the contact information acquired by the proximity sensor 12 in addition to the authentication information. Specifically, the control unit 16 causes the biosensor light source 21 to emit laser light as measurement light when it is determined that the test site is in contact with the contact unit 14 based on the contact information.

  When controlling the measurement light emitted from the biosensor light source 21 based on the contact information in addition to the authentication information, the control unit 16 determines that the authentication information matches any of the specific information in the storage unit 15. If it is determined that the part to be examined is not in contact with the contact part 14, the laser light is not emitted from the biosensor light source 21. By doing in this way, the control part 16 can inject | emit a laser beam, when the contact part 14 is reliably contacted by the test site | part. The laser beam has high energy because it has high directivity and the same wavelength and phase. However, the laser beam is emitted when the contact portion 14 is not covered by the test site under the control of the control unit 16. Can be prevented. For this reason, for example, it is easy to avoid the danger of laser light being emitted and entering the eyes of the subject. Moreover, unnecessary power consumption can be suppressed by not emitting laser light while the biosensor 13 is not acquiring the biometric output.

  If the control unit 16 determines that the test site is not in contact with the contact unit 14, the control unit 16 may notify the notification unit 18 that the test site is not in contact with the contact unit 14. The notification can be performed by the method described in the error information notification described above.

  When the control unit 16 emits the laser light from the biosensor light source 21, the control unit 16 starts acquiring biometric output from the biosensor 13. And the control part 16 determines whether acquisition of the biometric output by the biosensor 13 was complete | finished. For example, the control unit 16 may determine that the acquisition of the biometric output has ended after a predetermined time has elapsed since the biosensor 13 started acquiring the biometric output. Further, for example, when the biological sensor 13 acquires a sufficient biological measurement output for measuring biological information, the control unit 16 may determine that the acquisition of the biological measurement output has ended.

  The control unit 16 may continue to acquire the contact information in the proximity sensor 12 while acquiring the biometric output from the biosensor 13. The control unit 16 may stop the emission of the measurement light from the biosensor light source 21 when determining that the test site is separated from the contact unit 14 based on the contact information acquired by the proximity sensor 12. Thereby, the control part 16 can prevent that a laser beam is inject | emitted accidentally, when a to-be-tested part leaves | separates from the contact part 14 during acquisition of a biometric output.

  When the control unit 16 determines that the acquisition of the biological measurement output is completed, the control unit 16 stops the emission of the laser light from the biological sensor light source 21. The control unit 16 applies the biological information generated by the biological information generation unit 17 based on the biological measurement output acquired by the biological sensor 13 to the subject specified by the authentication information acquired by the authentication sensor 11 when measuring the biological information. The data is stored in the storage unit 15 in association with each other. Thus, even when a plurality of subjects use the measuring device 10, the subject automatically measures the biological information associated with the subject by measuring the biological information using the measuring device 10. Can be stored in the storage unit 15. Therefore, even if a plurality of subjects use the measuring apparatus 10, the subject does not need to take the trouble of performing an operation for associating the biological information with itself.

  The biometric information generation unit 17 generates biometric information based on the output (biometric information output) of the biosensor light receiving unit 22. As shown in FIG. 1, the biological information generation unit 17 may be configured in the measurement device 10 as an independent functional unit different from the control unit 16, or may be configured as a part of the control unit 16. .

  Here, a blood flow measurement technique using the Doppler shift by the biological information generation unit 17 will be described. When the blood flow is measured, the control unit 16 irradiates the living body tissue (test site) with laser light from the living body sensor light source 21, and the scattered light scattered from the living body tissue by the living body sensor light receiving unit 22. Is received. And the biometric information generation part 17 calculates a blood flow based on the output regarding the received scattered light.

  In living tissue, scattered light scattered from moving blood cells undergoes a frequency shift (Doppler shift) due to the Doppler effect proportional to the moving speed of the blood cells in the blood. The biological information generation unit 17 detects a beat signal (also referred to as a beat signal) generated by light interference between scattered light from a stationary tissue and scattered light from a moving blood cell. This beat signal represents the intensity as a function of time. Then, the biological information generation unit 17 converts the beat signal into a power spectrum in which power is expressed as a function of frequency. In the power spectrum of the beat signal, the Doppler shift frequency is proportional to the blood cell velocity, and the power corresponds to the amount of blood cells. And the biometric information generation part 17 calculates | requires a blood flow rate by integrating a power spectrum of a beat signal by applying a frequency.

  FIG. 3 is a diagram showing an example of the arrangement of the biometric sensor 13, the authentication sensor 11, and the proximity sensor 12, and is a view when the contact portion 14 is viewed from the back side of the mobile phone 30 in FIG. Each sensor is arranged in the vertical direction in the order of the authentication sensor 11, the proximity sensor 12, and the biosensor 13 from the bottom of FIG. 3A (that is, from the end of the case of the mobile phone 30) toward the center of the case. ing. As shown in FIG. 3, the authentication sensor 11, the proximity sensor 12, and the biosensor 13 are arranged in this order from the housing end of the mobile phone 30, so that when the user places the finger on the contact portion 14, The second joint is easily caught on the casing edge of the mobile phone 30. Therefore, the user can easily fix the finger to the contact portion 14.

  In addition, as shown in FIG. 3, the authentication sensor 11, the proximity sensor 12, and the biosensor 13 are sequentially arranged from the housing end of the mobile phone 30, so that the first joint of the user's finger is connected to the authentication sensor 11. Get closer. That is, the authentication sensor 11 acquires authentication information at the first joint of the user's finger and the vicinity thereof. Since it is easy to acquire authentication information at the finger joint and in the vicinity thereof, the above arrangement facilitates the imaging of the vein pattern of the user's finger by the imaging unit 24, and the authentication accuracy of the authentication sensor 11 can be improved.

  FIG. 3B shows a state where the test site is brought into contact with the contact portion 14. For example, it is assumed that the subject has registered specific information in the state shown in FIG. When the subject uses the measuring apparatus 10, if the contact part 14 does not contact the test site at the same position as in FIG. 3B in which the specific information is registered, the authentication information and the specific information Biometric information cannot be measured. On the other hand, when the subject brings the test site into contact with the contact portion 14 so that the authentication information and the specific information match, the same site is arranged at a position corresponding to the biosensor 13 in the test site. Therefore, every time the subject measures the biological information, the subject can measure the biological information at the same subject site. Therefore, since the error of the measurement condition of biological information can be reduced, the reliability of biological information can be improved.

  Next, an example of laser light emission control performed by the control unit 16 on the biosensor light source 21 will be described with reference to the flowchart shown in FIG. The flow illustrated in FIG. 4 is started when, for example, the measurement apparatus 10 is in a state in which the blood flow rate can be measured by an operation on the measurement apparatus 10. At the start of this flow, no laser light is emitted from the biosensor light source 21.

  The control unit 16 activates the authentication sensor 11 and the proximity sensor 12 so that authentication information and contact information can be acquired, respectively (step S101).

  The control part 16 acquires authentication information in the authentication sensor 11 by irradiating the test site with near infrared light from the authentication sensor light source 23 (step S102).

  The control unit 16 determines whether or not the authentication information acquired by the authentication sensor 11 matches the specific information stored in the storage unit 15 (step S103).

  When it is determined that the authentication information does not match the specific information (No in step S103), the control unit 16 notifies error information (step S104). When the error information includes, for example, a notification instructing to move the position of the test site that contacts the contact unit 14, the subject can determine the test site that contacts the contact unit 14 based on the instruction. The position can be moved (shifted). And the control part 16 acquires authentication information in the authentication sensor 11 again in the state which the position of the to-be-tested part moved (step S102).

  When it is determined that the authentication information matches the specific information (Yes in step S103), the control unit 16 stops driving the authentication sensor 11 (step S105).

  Next, the control unit 16 obtains contact information from the proximity sensor 12 by irradiating the test site with infrared light from the proximity sensor light source 25 (step S106).

  Based on the contact information acquired by the proximity sensor 12, the control unit 16 determines whether or not the test site is in contact with the contact unit 14 (step S107).

  When the control unit 16 determines that the test site is not in contact with the contact unit 14 (No in step S107), the control unit 16 notifies the subject that the test site is not in contact with the contact unit 14 ( Step S108). Then, the flow moves to step S106.

  When the control unit 16 determines that the test site is in contact with the contact unit 14 (Yes in step S107), the control unit 16 emits laser light from the biosensor light source 21 (step S109). Acquisition of the biometric output by the biosensor 13 is started by the emission of the laser light.

  The control unit 16 determines whether or not the biometric output from the biosensor 13 has been acquired (step S110).

  When it is determined that the biometric measurement output has not been acquired (No in Step S110), the control unit 16 acquires contact information from the proximity sensor 12 (Step S111).

  Based on the contact information acquired by the proximity sensor 12, the control unit 16 determines whether or not the test site is in contact with the contact unit 14 (step S112).

  When the control unit 16 determines that the test site is in contact with the contact unit 14 (Yes in step S112), the flow proceeds to step S110.

  On the other hand, when the control unit 16 determines that the test site is not in contact with the contact unit 14 (No in step S112), the control unit 16 stops emitting the laser light from the biosensor light source 21 (step S113). Then, the flow moves to step S106.

  In step S110, when the control unit 16 determines that the acquisition of the biological measurement output is completed (Yes in step S110), the control unit 16 stops the emission of the laser light from the biological sensor light source 21 (step S114).

  The control unit 16 stops driving the proximity sensor 12 (step S115). In this way, the acquisition of the biological measurement output in the biological sensor 13 is completed.

  When acquisition of the biometric output is completed, the biometric information generation unit 17 generates biometric information based on the biometric output.

  In addition, this invention is not limited only to the said embodiment, Many deformation | transformation or a change is possible. For example, the functions included in each component, each step, etc. can be rearranged so that there is no logical contradiction, and multiple components, steps, etc. can be combined or divided into one It is.

  In the embodiment described above, the test site is a finger, but the test site is not limited to a finger. The test site may be a site other than a finger, such as a palm. When the test site is a palm, the subject brings the palm into contact with the contact unit 14 when measuring biological information. The authentication sensor 11 acquires a palm vein pattern as authentication information, and the control unit 16 controls the emission of laser light from the biosensor light source 21 based on the palm authentication pattern.

  The arrangement of each of the authentication sensor 11, the proximity sensor 12, and the biosensor 13 is not limited to the example shown in FIG. The authentication sensor 11, the proximity sensor 12, and the biosensor 13 can be arranged at arbitrary positions that can fulfill their functions. For example, the proximity sensor 12 can be disposed at any position where contact information regarding the contact state between the test site and the contact portion 14 can be acquired. Specifically, the proximity sensor 12 can be disposed, for example, in the vicinity of the periphery of the biological sensor 13.

  Depending on the arrangement of each sensor, the measuring apparatus 10 does not necessarily have to be in contact with one finger as in the above embodiment. The measuring device 10 may measure biological information by bringing a plurality of fingers into contact with each other.

  FIG. 5 is a diagram illustrating a modified example of the arrangement of the biosensor 13, the authentication sensor 11, and the proximity sensor 12. In the example shown in FIG. 5, the authentication sensor 11 and the proximity sensor 12 are arranged side by side in the vertical direction, and the biosensor 13 is arranged at a position side by side with the authentication sensor 11. That is, the biometric sensor 13 and the authentication sensor 11 are arranged along the casing end of the mobile phone 30. When each sensor is arranged as shown in FIG. 5, the subject measures biological information by bringing two fingers into contact with the contact portion 14. For example, in the contact unit 14, the subject brings the index finger of the right hand into contact with a position corresponding to the biosensor 13, and the middle finger of the right hand is brought into contact with positions corresponding to the authentication sensor 11 and the proximity sensor 12. The control unit 16 controls the emission of the laser light emitted from the biosensor light source 21 to the index finger based on the authentication information and contact information on the middle finger. In the measurement apparatus 10, the control unit 16 acquires biometric information from the index finger in this way, and the biometric information generation unit 17 generates biometric information based on the biometric information.

  In the above-described embodiment, the case where the mobile phone 30 includes the measurement device 10 has been described. However, the electronic device on which the measurement device 10 is mounted is not limited to the mobile phone 30. For example, the measuring device 10 can be mounted on various electronic devices such as a personal computer, a computer operating mouse, a music player, a wristwatch, a tablet terminal, a game machine, and an entrance / exit management device.

  The measurement of biological information may be started when the subject performs an operation to start measuring biological information with respect to the measurement apparatus 10. For example, measurement of biological information may be started when the subject activates a dedicated application for measuring biological information using the mobile phone 30 on which the measurement device 10 is mounted. In this case, when the dedicated application is activated, the flow of FIG. 4 is started.

  The measurement of the biological information may be started when the subject does not perform an operation for measuring the biological information with respect to the measurement device 10. For example, when the measuring apparatus 10 is mounted on a mobile phone that unlocks by vein pattern authentication, when the subject performs the unlocking operation, the measuring apparatus 10 performs biometric information along with vein pattern authentication. May be measured. In a login operation on a personal computer or the like, biometric information can be measured by the same method. In such a case, when the unlock operation screen or the login screen is displayed, the control unit 16 activates the authentication sensor 11 and the proximity sensor 12 as shown in step S101 of FIG. Make contact information available. By measuring the biological information in this way, the biological information can be easily measured and the measurement results can be accumulated without the subject being aware of it. For example, when the subject performs a login operation of the personal computer at approximately the same time every day, the measuring apparatus 10 can accumulate periodic biological information at approximately the same time every day.

  In the above embodiment, the biological information generation unit 17 included in the measurement device 10 has been described as generating biological information based on the output of the biological sensor light receiving unit 22, but the generation of biological information is performed by the biological information included in the measurement device 10. It is not restricted to the case where the production | generation part 17 performs. For example, a server device connected to the measurement apparatus 10 via a wired or wireless network or a combination thereof includes a functional unit corresponding to the biological information generation unit 17, and the generation of biological information is a server having this functional unit. It may be performed on the device. In this case, the measurement apparatus 10 acquires authentication information by the authentication sensor 11, and transmits the acquired authentication information to the server apparatus from a separately provided communication unit. The server device determines whether the received authentication information matches the specific information stored in the storage unit included in the server device. The determination result is transmitted to the measuring apparatus 10. If they do not match, the measuring apparatus 10 notifies error information. On the other hand, if they match, the measuring apparatus 10 obtains a biological information output from the biological sensor 13 by emitting laser light from the biological sensor light source 21. The measuring apparatus 10 transmits the acquired biological information output to the server apparatus from a separately provided communication unit. The server device generates biometric information based on the biometric information output, and stores the generated biometric information in the storage unit in association with the subject specified by the authentication information. As described above, when the server device generates biometric information and stores the specific information and the biometric information, the measurement device 10 can be compared with the case where all the functional units illustrated in FIG. 1 are realized on one measurement device 10. Miniaturization and the like can be realized.
