dex)], for example, RA
The value of the subject's weight / (height) 2 stored in advance in M8 is displayed.

FIG. 3 is a block diagram showing a circuit configuration of the body fat measuring device according to the present embodiment, which is arranged in the case 1. As shown in FIG. In this block diagram, the oscillation circuit 1
5 and a V / I circuit are high-frequency current generation circuits (specifically, 15 is an oscillation circuit, and V / I circuit 14 is a circuit that generates a high-frequency current from the AC voltage oscillated by the oscillation circuit). The V / I circuit 14 is a high-frequency current output electrode 2,
6 is connected. The voltage detection electrodes 3 and 7 are:
A signal amplifier 11 including a filter, a traveling integrator 12, A /
It is connected to the CPU 10 via the D converter 13. C
The PU 10 is connected to an ultrasonic height input unit S, a weight measuring unit T, the key input units 51 to 54 and the display unit 4, and also connected to a RAM 8 and a ROM 9. The ultrasonic height input section S is for inputting data received from the ultrasonic receiving section 500, and the weight measuring section T is for inputting data from the weight measuring section 600.

The CPU 10 displays time information by executing a time information display process and a body fat measurement process described below in accordance with a program stored in the ROM 9.
And control of height measurement, weight measurement, and body fat measurement by mode switching. The RAM 8 is used as a work (time information register) of the CPU 10 and is also used as a memory for storing data such as height, weight, age, and gender of the subject, which is input or measured in advance by key operation. You.

In the present embodiment having the above configuration, when measuring the height and weight, the subject wears the left arm with the belts 16 and 17 and sets the display mode for height and weight. . Then, the CPU 10 operates according to the flowchart shown in FIG. 4 based on the program stored in the ROM 9, and captures the approximate height value input by the key operation by the subject (step S101).

Next, it is determined whether or not the ultrasonic measurement start switch 401 is on (step S102). In other words, as shown in FIG. 8A, the subject H wearing the wristwatch U on the left arm presses the front side of the case 1 against the top of the head with the left arm raised. Then, the ultrasonic measurement start switch unit 401 is pressed and turned on. In response to this, the ultrasonic transmitter 400 performs intermittent transmission of ultrasonic waves (step S103), and the ultrasonic receiver 500 performs intermittent reception of ultrasonic waves (step S104).

In other words, the received wave received by the ultrasonic receiving section 500 has a time lag that is proportional to each distance due to the reflection of the ultrasonic wave S1 at various places in the human body.
And a difference in amplitude. Among these, FIG. 8 (A)
As shown in FIG. 2, the reflection from the ground G on which the subject H stands is included. The ultrasonic waves reflected from the ground G properly indicate the height value of the subject H. Therefore, from the intermittently received ultrasonic waves, only the received ultrasonic waves that match the height value of the height setting set in step S101 are extracted (step S101).
105). Then, the height is calculated based on the extracted received ultrasonic waves (step S106), and the calculated height value is stored in the RAM 8 (step S107).

Next, the body weight is measured, and the measured value is taken as RA.
It is stored in M8 (step S108). When the weight is measured, the wristwatch U is detached from the wrist, placed upward at an appropriate place, and the two belts 1 are placed as shown in FIG.
Both feet are placed on the weight measuring units 600 of Nos. 6 and 17. Thereby, the weight of the subject H is measured, and the value is stored in the RAM.
8 is stored. When the weight measurement is completed, the age and gender are manually input by performing key operations while holding the watch U, and these data are stored in the RAM 8 (step S109). move on.

Therefore, by performing the processing according to the flowchart shown in FIG. 4, the RAM 8 stores the height, weight, age, and sex data of the subject H.

When the storage of these data is completed,
The subject wears the left arm with the belts 16 and 17.
As a result, the electrodes 6 and 7 on the back surface contact the skin of the left arm of the subject. And when performing body fat measurement,
After a predetermined key operation is performed to switch the mode and set the measurement mode, the right hand is brought into contact with the electrodes 2 and 3 on the front side, respectively. Thereby, as shown in FIG. 3, the high-frequency current output electrodes 2, 6 and the voltage detection electrodes 3,
7 and the human body of the person to be measured form a loop and become conductive.

On the other hand, the CPU 10 operates according to the flowchart shown in FIG. 5 based on the program stored in the ROM 9, and waits until the setting of the measurement mode is detected (step S1). When the measurement mode is detected, the previous measurement data in the work area is initialized (Step S2). Next, data such as the height, weight, age, and gender of the subject are sequentially read from the RAM 8 (step S3). These data have already been stored in the RAM 8 by the processing shown in the flowchart of FIG. Then, a BMI index is calculated based on the read weight and height (step S4).

Thereafter, the measurement is started, and the potential between the electrodes 3 and 7 for voltage detection is taken out (step S5). At this time, the presence or absence of a measurement error due to poor contact between the electrodes 2, 3, 6 and 7 is determined. It is detected (step S6). When a measurement error is detected, an error is displayed on the display unit 4 (step S9), and the error display is continued until a predetermined time has elapsed (step S10).

If no measurement error is detected, the body impedance is determined from the potential between the voltage detection electrodes 3 and 7 extracted in step S5, and based on the body impedance and the height and weight read in step S3. Then, the body fat percentage is calculated by performing a known calculation (step S7). Thereafter, the BMI calculated in step S4 and the body fat percentage calculated in step S7 are displayed on the display unit 4 (step S8), and at the same time, the height and weight values are also displayed.

At this time, according to the calculated body fat percentage,
The segment 4a corresponding to the order of "thin", "normal", "light obesity", and "obesity" is turned on. Therefore, as shown in FIG. 2, the display unit 4 displays “FAT 23.5%”, “BMI 21”, and “height:
176 cm "and" weight: 65 kg "are displayed, and according to the calculated body fat percentage and the BMI index,
The segments 4a are sequentially turned on. Therefore, if this body fat measurement device is worn on the arm, the measurement of the height, weight, and body fat percentage can be performed at any time by setting the measurement mode and bringing the other finger into contact with the electrodes 2 and 3 on the front side. Can be done easily and quickly. Further, by visually recognizing the printed character corresponding to the lit segment 4a, it is possible to recognize the level of the body fat percentage of the subject himself / herself. As described above, the ratio (%) of the fat mass to the human body can be displayed instead of the FAT by switching the display by operating the predetermined key.

FIG. 6 shows an example of the arrangement of the electrodes 2, 3 arranged on the front side in the first embodiment of the present invention. That is, FIG. 2A is an example in which the electrodes 2 and 3 are arranged on both sides of the display unit 4 in the case 1. (B) is an example in which it is arranged at the upper right corner and the lower left corner, and (C) is an example in which it is arranged at the upper left corner and the lower right corner. (D) shows an example in which one of the electrodes 2 and 3 is arranged on the belt 16 and the belt 17, respectively. As shown in these modified examples, the electrodes 2 and 3 do not contact the arm when the body fat measurement device is worn on the arm by the belts 16 and 17 but can contact with the other finger. When the body fat measurement device is mounted on the left arm of the subject, the electrode may be at any position as long as the electrode 2 is located outside the electrode 3 with respect to the human body of the subject. However, when the electrodes 2 and 3 are arranged on the case 1 side, there is an advantage that current supply and voltage detection to the electrodes 2 and 3 become easy and the circuit is simplified.

FIG. 7 shows an example of the arrangement of the electrodes 6 and 7 arranged on the back side in the first embodiment of the present invention. That is, FIG. 2A shows an example in which the electrodes 6 and 7 are arranged in the lateral direction on the back surface of the case 1. (B)
(C) is an example of disposing in the diagonally left direction. (D) is an example of being arranged on one belt 17, (E) is an example of being arranged on the other belt 16, (F) is one of the electrodes 6 and 7 on the belt 16 and the belt 17, respectively. This is an example of arrangement. As shown in this modification, the electrodes 6 and 7 can contact the skin of the arm when the body fat measurement device is worn on the arm by the belts 16 and 17, and the electrodes 6 and 7 are applied to the left arm of the subject at the time of measurement. When the body fat measurement device is mounted, if the electrode 6 is located outside the electrode 7 with respect to the human body of the subject,
It may be at any position.

Of course, the arrangement examples shown in FIGS. 6A to 6D and the arrangement examples shown in FIGS. 7A to 7F can be appropriately combined and used.

In this embodiment, according to the calculated percentage of body fat and the BMI index, “thin”, “normal”
Although the segments 4a corresponding to "light obesity" and "obesity" are sequentially turned on, the segments 4a corresponding to any of "thin", "normal", "light obesity", and "obesity" may be turned on. For the display of these measurement results,
Character display using a dot matrix, animation display, and the like can be changed as appropriate.

(Second Embodiment) FIG. 9 shows a second embodiment of the present invention. As shown in FIG. 1A, in this body fat measurement device, a case 1 is a case body 1a.
And a lid 1b. As in the above embodiment, a pair of belts 16 and 17 are locked to the case main body 1a, key input sections 51, 52, 53 and 54 are provided, and the electrodes 2 and 3 are arranged on the surface. ing. The lid 1b is pivotally supported on one side edge of the case main body 1a so as to be openable and closable at an arbitrary angle. The case main body 1a has a sensor for detecting that the case main body 1a and the lid 1b are opened at a predetermined angle or more. 55 are provided. This sensor 55
Is a light amount detection sensor that detects that the case main body 1a and the lid 1b are opened by a predetermined angle or more based on the illuminance on the case main body 1a that changes when the lid 1b is opened, but may be a contact switch. The lid 1b is provided with a display unit 4 similar to that of the above-described embodiment on the back side in contact with the case body 1a in a closed state, and a time display unit (not shown) is provided on the front side. Have been. further,

In this embodiment, the circuit shown in FIG. 3 is provided in the case body 1a, and although not shown, a clock circuit for displaying the time on the time display unit is provided on the lid 1b side. Is built-in.

In the present embodiment according to the above configuration, the subject is usually worn on one arm with the belts 16 and 17 (when viewing time information and the like), and at this time, the lid 1b is closed. In a state where Thereby, the time display portion arranged on the surface of the lid 1b is located on the upper surface, and can be used as a normal wristwatch. When performing body fat measurement, as shown in FIG.
b is opened by a predetermined angle or more to stand up. Then, the sensor 55 detects that the lid 1b is opened by a predetermined angle or more and outputs a detection signal to the CPU 10, and the CPU 10 automatically switches from the time display mode to the measurement mode. Therefore, the processes after step S2 in the flowchart shown in FIG. 5 are executed, and the BMI and the body fat percentage are displayed.

According to the present embodiment, since the electrodes 2 and 3 can be arranged by using the entire surface of the case body 1a, the electrodes 2 and 3 can be made large and the measurement accuracy can be increased. . In addition, by closing the lid 1b during non-measurement, it is possible to prevent the electrodes 2 and 3 from being contaminated, to suppress the occurrence of errors during measurement, and to hide the electrodes 2 and 3 from the viewpoint of design. This is advantageous.
Furthermore, when the lid 1b is opened, the mode can be automatically shifted to the measurement mode, whereby the measurement can be started smoothly and the measurement of the fat percentage can be performed more easily and quickly.

Further, by providing the circuit shown in FIG. 3 on the case body 1b side and the clock circuit section (not shown) on the lid 1b side, for example, a current generation circuit (oscillation circuit 1)
5 and a V / I circuit 14) can be expected to have a so-called shielding effect, which makes the clock circuit less susceptible to noise due to the high frequency voltage or high frequency current generated in the V / I circuit 14).

Further, according to the first and second embodiments, the subject is prepared to put out the measuring device for the purpose of measuring the body fat, or both hands are free. Since it is possible to eliminate the inconvenience of having to perform the measurement, the body fat can be easily measured at any time.

(Third Embodiment) FIG. 10 shows a third embodiment of the present invention. This body fat measuring device is similar to the first embodiment in the case 110 and the case 110. The body 110 includes a pair of belts 16 and 17 locked to opposing sides of the case 110, and the weight measurement unit 600 is disposed on the belts 16 and 17.
Is arranged. However, unlike the first embodiment, the key input unit 5 provided on one side of the case 110 is different from the first embodiment.
3 and 54 also serve as high-frequency current output electrodes 2 and 6,
The key input units 51 and 52 provided on the other side also serve as the voltage detection electrodes 3 and 7.

In the present embodiment having the above configuration, when displaying the current time, the 12-6 o'clock direction is displayed as the vertical direction as shown in FIG. When performing the body fat measurement, the body fat measuring device is detached from the arm, and as shown in FIG. 10B, the key input units 51 and 53 are pressed so as to be sandwiched between the left thumb 601 and the index finger 602, and the right thumb is pressed. The key input units 52 and 54 are pressed so as to be sandwiched between the index finger 701 and the index finger 702. Thereby, the left hand is the high-frequency current output electrode 2
And the right hand contacts the high-frequency current output electrode 6 and the voltage detection electrode 7. As a result, as shown in FIG.
6 is in a state of conduction with the voltage detection electrodes 3 and 7 via the human body.

In this way, the key input unit 5 can be operated with both hands.
1 to 54, these four key input sections 51 to 51
54 becomes a state of simultaneous pushing. Then, the CPU 10 detects the simultaneous pressing of the key input units 51 to 54 and displays the same on the display unit 4.
Set the 3-9 o'clock direction to the vertical direction (3 o'clock direction is up) and automatically switch to the measurement mode. Therefore, the processes after step S2 in the flowchart shown in FIG. 5 are executed, and the BMI and the body fat percentage are displayed.

In this case, the display section 4 is constituted by a dot matrix liquid crystal, and in the first and second embodiments,
As a substitute for the letters “slim”, “normal”, “light obesity”, and “obesity” printed on the display unit 4, the content corresponding to the measurement result is selected from among these four steps and displayed on the display unit 4. To be displayed.

According to the present embodiment, the case 11
Since there is no need to separately arrange a plurality of electrodes 2, 3, 6, 7 on the 0 itself, it is advantageous in terms of design and space, and also serves as the key input units 51 to 54.
When all the buttons are pressed at the same time, the mode automatically shifts to the measurement mode, and the measurement of the body fat percentage can be started as it is, so that the measurement of the body fat percentage can be more easily and quickly performed.

In the case of the third embodiment, the electrodes 2, 3, 6, 7 may be arranged corresponding to the key input sections 51, 52, 53, 54, respectively.

(Fourth Embodiment) FIGS. 11 to 15
This shows a fourth embodiment of the present invention, in which a wristwatch-type body fat measurement device can easily perform accurate measurement without violating the measurement principle.
That is, in body fat measurement using the four-terminal electrode method, a loop passing through the human body formed by a pair of output electrodes for outputting a high-frequency current is a pair of detection electrodes for detecting a voltage. It is necessary to bring each electrode into contact with the skin of the human body so that it is larger than the loop that passes through the body. However, for example, in the arrangement configuration of the electrodes 6 and 7 shown in FIG. 1B, when the electrode 6 is mounted on the left wrist, the electrode 6 is on the hand side and the electrode 7 is on the near side closer to the body, and is mounted on the right hand. On the contrary, the electrode 6 is on the near side and the electrode 7 is on the near side. Therefore, assuming that the electrode 6 is for high-frequency output, when the electrode 6 is mounted on the left hand,
A loop passing through the human body formed by a pair of output electrodes for outputting a high-frequency current is larger than a loop passing through the human body formed by a pair of detection electrodes for detecting voltage. If you wear it, it will not be so,
Accurate measurement becomes difficult.

Therefore, whether the device is worn on the left or right arm is an important requirement for enabling accurate measurement. Therefore, in the present embodiment, the characteristic QRST of the first lead of the electrocardiogram led from the left and right arms.
By determining the polarity of the waveform, especially the R-wave, the arm on which the device is mounted is specified, and the role of the four electrodes, that is, a pair of outputs for outputting high-frequency currents, is determined by the results of the specification. An electrode is used to determine whether to use a pair of detection electrodes for detecting a voltage.

The output is provided to the CPU 10.

In the present embodiment having the above-described configuration, the person to be measured has the height described in the flowchart of FIG.
When the measurement of the weight is completed, it is worn on one arm by belts 16 and 17. Thereby, the electrode 6 on the back side,
7 contacts the skin of one arm of the subject. Then, when performing body fat measurement, perform a predetermined key operation,

Thereafter, the switches SW1, SW2, S
The movable contacts of W5 and SW6 are fixed contacts C2, C4, and C, respectively.
9 and C12, the switch control circuit 19 is controlled (step S14), and the movable contacts of the switches SW3 and SW4 are fixed contacts C6 and C4, respectively.
7 so that the switch control circuit 20
Is controlled (step S15). As a result, the electrodes 2 and 3 arranged on the front side are temporarily short-circuited, and the electrode 7 among the electrodes 6 and 7 arranged on the back side acts as an induction electrode for detecting a cardiac radio wave. Function as common electrodes for detecting the electromagnetic wave of the device.

In order to obtain the first guided heart radio wave with such an electrode arrangement, as shown in FIG. 13, the differential amplifier circuit 18 regards the electrode 6 as a common level or reference signal, and sets the electrode 2 (3 ) Is obtained. At the same time, the potential of the electrode 7 is obtained, and the potential difference between the electrode 2 (3) and the electrode 7 is obtained. Since the potential difference obtained in this manner has a strength of about several millivolts, the signal amplifier 1 is used for easy detection.
The signal is amplified by 84 and supplied to the CPU 10.

As a result, the CPU 10 can obtain the first lead radio wave including the characteristic QRST waveform as shown in FIG. 15 (a) or (b). Therefore, in the next step S16, it is determined whether or not the heart waves can be detected from the electrodes 2 and 3, in particular, whether or not the R wave determined in the next step S18 has been detected (step S16). If the error cannot be detected, an error is displayed on the display unit 4 (step S17), and the process proceeds to step S10 in FIG. 5 and the error display is continued until a predetermined time has elapsed.

If a heart radio wave, in particular, an R wave can be detected, the polarity of the R wave is determined (step S18), and the direction of the spike signal of the R wave is determined to be positive or negative (step S19). ). That is, the polarity of the spike signal of the R wave is reversed depending on whether the arm on which the device is mounted is left or right, and the device is mounted on the left wrist and the right finger is applied to the electrode 2 (3).
When a signal is detected while touching the
As shown in (a), the R wave becomes a negative spike signal. Conversely, the device is attached to the right wrist and the left finger is
When a signal is detected while making contact with (3), the R-wave becomes a positive spike-like signal as shown in FIG.

Therefore, if the result of the determination in step S19 is that the spike signal of the R wave is in the negative direction, the body fat measuring device according to the present embodiment is mounted on the left wrist, and the electrodes 2 and 3 is touched. In this case, the switch control circuit 19 is controlled so that the movable contacts of the switches SW1, SW2, SW5, and SW6 are connected to the fixed contacts C1, C3, C10, and C11, respectively (Step S).

At this time, when the body fat measurement device is mounted on the left wrist as described above, the electrode 6 (electrode for outputting high-frequency current) is on the finger side far from the body and the electrode 7
(Electrode used for voltage detection) is closer to the body than this. If the right finger touches the electrode 3 with the second finger and the third finger longer than the second finger touches the electrode 2, the electrode 2 (electrode for high-frequency current output) is far from the body and the electrode 3
(Electrode used for voltage detection) is closer to the body than this. Therefore, the loop through the human body formed by the pair of electrodes 2 and 6 for outputting the high-frequency current is larger than the loop through the human body formed by the pair of electrodes 3 and 7 for detecting the voltage. . Therefore, by starting the measurement in this state (step S23), the body fat can be accurately measured.

On the other hand, as a result of the determination in step S19, R
If the spike signal of the wave is in the positive direction, the body fat measurement device according to the present embodiment is attached to the right wrist, and the electrode 2 is
3 is touched. In this case, the switches SW1, SW2, SW5, S5, as in step S20 described above.
The movable contacts of W6 are fixed contacts C1, C3, C10, C
11 so that the switch control circuit 1

The switch control circuit 20 is controlled so that the movable contacts of W3, SW4, SW7, and SW8 are connected to the fixed contacts C5, C8, C13, and C16, respectively (step S2).
5). Thus, the electrodes 3 and 7 are set as high-frequency current output electrodes, and the electrodes 2 and 6 are set as voltage detection electrodes (step S26).

At this time, when the body fat measuring device is attached to the right wrist as described above, the electrode 7 (electrode for outputting high-frequency current) is on the hand side far from the body, and the electrode 6
(Electrode used for voltage detection) is closer to the body than this. When the right finger touches the electrode 2 with the second finger and touches the electrode 3 with the third finger longer than the second finger, the electrode 3 (the electrode used for high-frequency current output) is far from the body and the electrode 2
(Electrode used for voltage detection) is closer to the body than this. Therefore, a loop through the human body formed by the pair of electrodes 3 and 7 for outputting a high-frequency current is larger than a loop through the human body formed by the pair of electrodes 2 and 6 for detecting voltage. . Therefore, by starting the measurement in this state (step S23), the body fat can be accurately measured.

In the present embodiment having the above configuration, the subject is worn on one arm by the belts 16 and 17. As a result, the electrodes 61 and 71 on the back surface contact the skin of one arm of the subject. Then, when performing body fat measurement, a predetermined key operation is performed to set a body fat measurement mode. Then, the CPU 10
The operation is started according to the flowchart shown in FIG. 18 based on the program stored in the storage area, and the previous measurement data in the work area is initialized (step S1)
1). Next, data such as the height, weight, age, and gender of the subject stored in the RAM 8 are sequentially read out by the processing shown in the flowchart of FIG. 4 (step S12), and the read weight and height are read out. Based on the above, the BMI index is calculated (step S13).

Thereafter, both switch switching control circuits 3
By controlling the electrodes 0 and 34, the electrodes 6 and 7 are connected to the V / I circuit 14, and a high-frequency current is output from the electrodes 6 and 7 (step S35). Next, the switching control circuit 34 is controlled to connect the electrodes 31 and 32 to the signal amplifier 11,

If no voltage is detected in any of the above,
An error is displayed on the display unit 4 (step S36), and the process proceeds to step S10 in FIG. 5 and the error display is continued until a predetermined time elapses.

If a voltage is detected at one of the electrodes 31 and 32 at step S35, it is determined which of the electrode 31 and the electrode 32 has detected a normal signal (step S37). ). That is, as described above, in the body fat measurement device according to the present embodiment,
Electrodes 2 are provided at both corners of case 130 near belt 16.

In the state of being attached to 1, the electrode 6 for high-frequency current output is on the hand side far from the body, and the electrode 7 for voltage detection is on the hand side closer to the body as described above. When the right finger first finger 701 touches the electrode 31 and the second finger 702 longer than the first finger touches the electrode 21, the electrode 21 for high-frequency current output is far from the body and used for voltage detection. The electrode 31 is closer to the body than this. Therefore, a pair of electrodes 21 for outputting a high-frequency current,
The loop formed by the body 6 and passing through the human body is larger than the loop formed by the pair of electrodes 31 and 7 for detecting the voltage and passing through the human body. Therefore, by performing the measurement calculation in this state, the body fat can be accurately measured.

On the other hand, if the result of the determination in step S37 is that the electrode 32 has detected a normal signal, the apparatus is mounted on the right wrist 71 as shown in FIG.

Is also close to the torso. Also,
When the first finger 601 of the left hand touches the electrode 32 and the second finger 602 longer than the first finger touches the electrode 22, the electrode 22 for high-frequency current output is far from the body, and the electrode 32 for voltage detection is used. Is closer to the fuselage than this. Therefore, the loop through the human body formed by the pair of electrodes 22 and 7 for outputting the high-frequency current is larger than the loop through the human body formed by the pair of electrodes 32 and 6 for detecting the voltage. .

Also, when the right second finger 72 touches the electrode 22 and the third finger 73 longer than the second finger touches the electrode 32, the electrode 32 for high-frequency current output is far from the body and used for voltage detection. The electrode 22 is closer to the body than this. Therefore, the loop through the human body formed by the pair of electrodes 32 and 6 for outputting the high-frequency current is larger than the loop through the human body formed by the pair of electrodes 22 and 7 for detecting the voltage. . Therefore, by performing the measurement calculation in this state, the body fat can be accurately measured.

In the present embodiment, FIG.
As shown in (b), when the device is mounted on the right wrist 71, it is appropriate that the second finger 62 of the left hand contacts the electrode 21 and the third finger 63 of the left hand contacts the electrode 31 on the diagonal line. It is assumed that the contact form is simple. Therefore, if the electrode 21 detects a normal signal as a result of the determination in step S47, it can be considered that the proper contact form shown in FIG. 21B is formed.
In this case, both switch switching control circuits 30, 3

Can be estimated. In this case, both switch switching control circuits 90 and 91 are controlled so that the electrode 23 and the electrode 7 are used as high-frequency current output electrodes, and
The measurement calculation of the body fat is executed using the and the electrodes 6 as the voltage detection electrodes (step S62).

At this time, in a state where the body fat measuring device is mounted on the left wrist, the electrode 6 for outputting a high-frequency current is the hand side far from the body and the electrode 7 for voltage detection is the same as described above. Is also close to the torso. Also,
When the left second finger 62 touches the electrode 33 and the third finger 63 longer than the second finger touches the electrode 23, the electrode 23 for high-frequency current output is far from the body and the electrode 33 for voltage detection. Is closer to the fuselage than this. Therefore,
The loop through the human body formed by the pair of electrodes 23 and 7 for outputting the high-frequency current is larger than the loop through the human body formed by the pair of electrodes 33 and 6 for detecting the voltage. Therefore, by performing the measurement calculation in this state, the body fat can be measured accurately, and since the measurement is performed with both arms extended, the measurement value can be made more accurate. it can.
