  As shown in FIG. 2B, a transmitter 17 for transmitting infrared rays is provided at the lower portion of the lower surface 21 in the height direction and at the center portion in the left-right direction. The transmission unit 17 transmits a signal including the measurement results of the foot measurement electrode 13 and the load sensor 14 of the main body device 10 to the gripping device 30 as infrared rays.

  As shown in FIG. 2C, when the front surface 22 and the lower surface 21 are set to 0 degree and 90 degrees, respectively, the infrared transmission range of the transmission unit 17 is set in a range of 30 degrees to 80 degrees. That is, the transmission unit 17 transmits infrared rays in a conical range with a central angle of 50 degrees.

A detailed configuration of the gripping device 30 will be described with reference to FIG.
As shown in FIG. 3A, the grip body 40 has a plurality of surfaces, that is, an upper side surface 40A, a lower side surface 40B, a right side surface 40C, a left side surface 40D, a front surface 40E, and a rear surface 40F (see FIG. 3B). ) Is formed.

The optical measurement unit 50 includes a first light receiving element 51 and a second light receiving element 52 as light receiving parts, and a light emitting element 53 as an irradiation part. The light emitting element 53, the first light receiving element 51, and the second light receiving element 52 are arranged in this order from above in the vertical direction.

  The light irradiated to the living body from the light emitting element 53 propagates in the living body while being scattered and absorbed, and appears again on the surface of the living body. This light is received by the first light receiving element 51 or the second light receiving element 52. Since subcutaneous fat becomes resistant to the movement of light, when the amount of subcutaneous fat in the living body is large, the amount of light transmitted from the living body to the surface of the living body is reduced. For this reason, the amount of light received by the first light receiving element 51 or the second light receiving element 52 is reduced. On the other hand, when the subcutaneous fat is small, the amount of light that propagates from the living body to the surface of the living body increases, so that the amount of light received by the first light receiving element 51 or the second light receiving element 52 increases.

  In the 1st light receiving element 51, the light which propagated to the biological body surface mainly before reaching | attaining muscle among the light irradiated in the living body from the light emitting element 53 is received.

Calculate fat mass.

With reference to FIG. 4, the electrical configuration of the biological information measuring apparatus 1 will be described.
The biological information measuring apparatus 1 includes a measuring unit 70 including electrodes and the like for measuring biological information, and a control unit 60 that performs various calculations by the calculation unit 61 based on information transmitted from the input unit 45 and the like. Including. In addition to this, a storage unit 80 that stores the calculation result of the control unit 60 and stores the calculation formulas necessary for the calculation in the control unit 60 in advance is included.

  Signals are transmitted and received between the input unit 45, the measurement unit 70, the storage unit 80, and the control unit 60 as follows. That is, the information input from the input unit 45, the detection value of the load sensor 14, the detection value of the foot measurement electrode 13, and the detection value of the hand measurement electrode 33 are input to the control unit 60. In addition, the storage unit 80 stores information input to the control unit 60, each detection value, and a calculation result of the control unit 60. Further, the control unit 60 reads out calculation result data and pre-stored calculation formula data and the like from the storage unit 80 as necessary. A command signal for energization is transmitted from the control unit 60 to the foot energizing electrode 12 and the hand energizing electrode 32. A command signal for display is transmitted from the control unit 60 to the display unit 44.

  The calculation unit 61 calculates a plurality of measurement items as biological information. As measurement items, for example, “body weight”, “BMI”, “body fat percentage”, “muscle level”, “basal metabolism”, “visceral fat level”, “subcutaneous fat percentage”, “subcutaneous fat mass”, “bone” Examples include “amount”, “body composition age” and “balance age”.

  The infrared transmission range and reception range will be described with reference to FIG. In the figure, the one-dot chain line indicates the infrared transmission range of the transmission unit 17, and the two-dot chain line indicates the infrared reception range of the reception unit 49.

  As shown in FIG. 5A, the receiving unit 49 is located within the infrared transmission range of the transmitting unit 17 in the attached state. That is, infrared communication can be performed between the transmission unit 17 and the reception unit 49.

  As shown in FIG. 5B, the receiving unit 49 is located within the infrared transmission range of the transmission unit 17 in the gripping state. That is, infrared communication can be performed between the transmission unit 17 and the reception unit 49.

  Here, for example, assuming that the receiving unit 49 is provided on the front surface 40E of the grasping main body 40, the range indicated by the broken line in the figure is the infrared receiving range of the receiving unit 49. In this case, when the gripping device 30 is tilted from the reference gripping state toward the near side by a certain amount or more, the receiving unit 49 is out of the infrared transmission range. At this time, since infrared communication is disabled between the transmission unit 17 and the reception unit 49, the measurement result is not displayed on the display unit 44.

  On the other hand, in the gripping device 30, the receiving unit 49 is provided on the lower side surface 40B. Therefore, even when the gripping device 30 is tilted from the reference gripping state toward the near side by a certain amount or more, the receiving unit 49 Is located within the infrared transmission range of the transmitter 17. For this reason, the state in which the infrared communication between the transmission part 17 and the receiving part 49 is possible is maintained. That is, compared with what assumed that the receiving part 49 was provided in the front surface 40E of the holding | maintenance main-body part 40, the situation where infrared communication becomes impossible by the inclination of the holding | grip apparatus 30 does not arise easily.

With reference to FIG. 5, the measuring method of biometric information is demonstrated.
As shown in FIG. 5A, when the user measures biological information, the user places it on the placement unit 11. When the impedance is not measured, the attachment state of the gripping device 30 is maintained. When the impedance is measured, the gripping state of the gripping device 30 is maintained.

  As shown in FIG. 5B, when measuring the impedance, the user grips the right hand grip 31A and the left hand grip 31B with the right hand and the left hand, respectively, and moves the lower side 40B of the grip body 40 downward. Hold towards. Also, keep the arm in a horizontal position with your elbows extended forward.

  In the attached state and the gripped state, the biological information measuring device 1 notifies that the measurement is completed, and then the measurement result of the biological information is displayed on the display unit 44. When the user wants to confirm another measurement result that is not displayed on the display unit 44, the user operates the switching unit 48 to switch the display content of the display unit 44. Further, when it is desired to compare the current measurement result with the past measurement result, the display content of the display unit 44 is switched by operating the comparison button 47.

A method for measuring the amount of subcutaneous fat will be described.
When measuring the amount of subcutaneous fat, the user operates the measurement start button 46 in a state where the optical measurement unit 50 on the back surface 40F of the grasping main body unit 40 is pressed against the surface of the living body. Thereby, light emission and light reception by the optical measurement unit 50 are started. Then, the amount of subcutaneous fat calculated based on the measurement result of the amount of received light is displayed on the display unit 44.

The biometric information measurement procedure will be described with reference to FIG.
In step S110, the user turns on the power switch 15.
In step S120, the user determines whether or not his / her user information has already been registered. If the user information has already been registered, the process of step S130 is performed. When the user information is not registered, steps S140 and S150 are performed.

  In step S130, the user operates the personal button of the input unit 45. At this time, the control unit 60 reads the user information stored in association with the user number of the operated personal button from the storage unit 80.

In step S140, the user operates the registration button of the input unit 45. At this time, the control unit 60 displays the content for registering user information on the display unit 44.
In step S150, the user operates the selection button and the setting button of the input unit 45 to register user information (age, sex, and height). At this time, the control unit 60 stores the input user information and the user number in the storage unit 80 in association with each other.

  In step S <b> 160, the user determines whether or not to measure biological information using the gripping device 30. When measurement is performed using the gripping device 30, in step 170, the right hand grip 31A and the left hand grip 31B are gripped by the right hand and the left hand, respectively, and the grip state is maintained. When measurement is performed without using the gripping device 30, the attachment state is maintained without gripping the gripping device 30 in step S180.

In step S190, the user is placed on the placement unit 11 in a standing state. When the gripping device 30 is gripped, the gripping device 30 is held at a predetermined position.
In step S200, the user determines whether to measure the subcutaneous fat mass. When measuring the amount of subcutaneous fat, the measurement start button 46 is operated after the optical measurement unit 50 of the grasping main body 40 is pressed against the measurement target part of the living body in step S210.

  When the user holds the posture for measurement on the placement unit 11, a change in voltage corresponding to the body weight is measured by the load sensor 14. When the gripping device 30 is not gripped, a current is passed between the user's feet by the foot energizing electrode 12 and a voltage of the same current is measured by the foot measuring electrode 13. Further, when the gripping device 30 is gripped, a current flows between the right hand right foot and the left hand left foot by the foot energizing electrode 12 and the hand energizing electrode 32, and the voltage of the same current is generated by the foot measuring electrode 13 and the hand measuring electrode 33. Measured. When the user operates the measurement start button 46, the amount of light that has propagated through the living body is measured.

  The control unit 60 calculates the weight based on the voltage measured by the load sensor 14. Further, the impedance is calculated based on the voltage measured by at least one of the foot measurement electrode 13 and the hand measurement electrode 33 and the user information corresponding to the personal button operated this time or the newly registered user information. In addition, the received light amount ratio is calculated based on the received light amount measured by the first light receiving element 51 and the second light receiving element 52.

  Then, based on the calculated weight, impedance, received light amount ratio, and user information, the numerical value or level of each measurement item is calculated. Here, “BMI”, “body fat percentage”, “muscle level”, “basal metabolism”, “visceral fat level”, “subcutaneous fat percentage”, “subcutaneous fat mass”, “bone mass”, “body composition age” ”And“ balance age ”are calculated.

  The control unit 60 converts the calculated numerical value and level of each measurement item into a signal for transmission by infrared rays. The converted signal is transmitted from the transmission unit 17 as infrared rays. Then, after the transmitted infrared ray is received by the receiving unit 49, information corresponding to the received signal is displayed on the display unit 44.

  In step 220, the user confirms the measurement result displayed on the display unit 44. When the measurement result displayed on the display unit 44 is to be changed, the switching unit 48 is operated. When it is desired to compare the current measurement result with the past measurement result, the comparison button 47 is operated.
