(First embodiment)
With reference to FIG. 1 and FIG. 2, the structure of the biological information measuring device 1 is demonstrated. The biological information measuring apparatus 1 includes a pedestal 10 on which a body is placed, four pedestals 20 that support the pedestal 10, and four load sensors 30 that measure a load applied to the placement surface 15. Further, the pedestal 10 is provided with a display unit 50 indicating weight and body fat percentage, four electrodes 40 for measuring the bioimpedance IB, and a control device 60 for controlling the entire apparatus.

  In the following description, in the biological information measuring apparatus 1, the direction in which the display unit 50 is provided is the front, and the opposite direction is the rear. When facing the display unit 50, the right side is the right direction, the left side is the left direction, and the left-right direction is the width direction. The side where the mounting surface 15 is located is the upper side, and the opposite side is the lower side. Further, the front side surface is the front surface 14 (back surface), the rear side surface is the rear surface 11 (front surface), the right side surface facing the front is the right side surface 12, and the left side surface is the left side surface 13. When the biological information measuring apparatus 1 is used, the toe portion of the foot is disposed on the front side of the pedestal 10 and the heel portion of the foot is disposed on the rear side. In the simple description of the drawings, a view seen from the front side is a rear view, and a view seen from the rear surface 11 is a front view.

  The pedestal 10 includes a pedestal main body 10A that accommodates the load sensor 30 and the control device 60, and a mounting table 10B provided on the pedestal main body 10A. The base body 10A and the mounting table 10B are fastened with screws or the like.

  The mounting table 10B is substantially square in plan view. That is, the front side and the rear side of the mounting table 10B are parallel and equal in length, and the left side and right side of the mounting table 10B are parallel and equal in length. The upper surface of the mounting table 10B is a mounting surface 15 on which the body is placed. A pedestal main body 10A is provided on the lower surface of the mounting table 10B. The side end of the mounting table 10B protrudes from the side surface of the base body 10A.

  The pedestal main body 10A is a quadrangular pyramid, and has an accommodating portion for accommodating the load sensor 30 and the control device 60 therein. The side surface of the pedestal main body 10A is formed in a trapezoid shape that narrows downward. The right side surface 12 of the pedestal main body 10A is provided so as to be inclined inwardly downward, and the angle θ formed between the right side surface 12 and the bottom surface 16 is an obtuse angle. The left side surface 13 has the same structure as the right side surface 12. Similarly, the front surface 14 and the rear surface 11 have the same structure as the right side surface 12.

  The left side surface 13, the right side surface 12, the front surface 14, and the rear surface 11 of the pedestal main body 10A are collectively referred to as side surfaces. That is, the side surface of the pedestal 10 refers to a surface connected to the bottom surface 16 of the pedestal main body 10A.

  Four holes 17 into which the pedestals 20 are fitted are formed on the lower surface of the base body 10A. Load sensors 30 are provided at positions corresponding to the respective holes 17 in the mounting table 10B. This load sensor 30 is fixed to the mounting table 10B. The foot 20 is fitted into the hole 17 and the upper surface thereof is applied to the load sensor 30. That is, the load sensor 30 is disposed between the mounting table 10 </ b> B and the foot 20. When a load is applied to the pedestal main body 10 </ b> A, a force is applied to the pedestal 20 via the load sensor 30.

The electrode 40 is for measuring the bioelectrical impedance IB.
The four electrodes 40 are distinguished as a first application electrode 41, a second application electrode 42, a first measurement electrode 43, and a second measurement electrode 44.

Each electrode 40 is formed in a shape corresponding to the shape of the foot as a mark indicating the place where the foot is placed.
Specifically, the first application electrode 41 is provided in a portion corresponding to the toe portion of the right foot. A second application electrode 42 is provided in a portion corresponding to the toe portion of the left foot. A first measurement electrode 43 is provided at a portion corresponding to the heel of the right foot. A second measurement electrode 44 is provided at a portion corresponding to the heel of the left foot. The first application electrode 41 and the first measurement electrode 43 constitute a right foot mark indicating a place where the right foot is placed. The second application electrode 42 and the second measurement electrode 44 constitute a left foot mark indicating the place where the left foot is placed.

  The first application electrode 41 and the second application electrode 42 are formed in a rectangular shape. The vertical width of the first application electrode 41 is approximately half the vertical dimension of the foot. The width of the first application electrode 41 is approximately the same as the width of the toe portion of the foot. The dimensions of the second application electrode 42 are the same as those of the first application electrode 41.

  The first measurement electrode 43 and the second measurement electrode 44 are formed in a rectangular shape. The vertical width of the first measurement electrode 43 is approximately half the vertical dimension of the foot. The width of the first measurement electrode 43 is equal to the width of the first application electrode 41. The dimensions of the second measurement electrode 44 are the same as those of the first measurement electrode 43.

  The first application electrode 41 and the second application electrode 42 are application electrodes for applying a high-frequency current to the body. Note that both electrodes have the same potential, and both electrodes are synchronized. The frequency of the applied current is set so as to penetrate the cell wall of the body.

  The first measurement electrode 43 is an electrode for measuring a potential. That is, when a high frequency current is applied to the body, the potential of the first measurement electrode 43 is measured. Similarly, the second measurement electrode 44 is an electrode for measuring a potential, and the potential of the second measurement electrode 44 is measured when a high-frequency current is applied to the body.

  The first measurement electrode 43 and the second measurement electrode 44 output signals synchronized with the first application electrode 41 and the second application electrode 42. Then, the difference between the amplitude of the first measurement electrode 43 and the amplitude of the second measurement electrode 44 (hereinafter referred to as “amplitude difference”) is detected by the difference circuit, and the bioimpedance IB is calculated based on this value. Note that the bioelectrical impedance IB increases as the amplitude difference increases. Since the bioimpedance IB is related to information such as body fat percentage, weight, sex, age, etc., the body fat percentage is calculated based on these information. The biometric information such as sex and age is input using an interface provided on the display unit 50 of the biometric information measuring apparatus 1.

  The load sensor 30 detects a load applied to the placement surface 15 and transmits a detection signal to the control device 60. The load sensors 30 are respectively provided at the four corners of the base body 10A. Specifically, a first load sensor 30 is provided at a portion corresponding to the toe portion of the right foot, and a second load sensor 30 is provided at a portion corresponding to the toe portion of the left foot. A third load sensor 30 is provided at a portion corresponding to the heel portion of the right foot, and a fourth load sensor 30 is provided at a portion corresponding to the heel portion of the left foot.

  The load sensor 30 includes a load cell having a strain gauge. The load cell is configured by a load cell main body and an action part that is deformed by receiving a load and moves relative to the load cell main body. The load cell main body is fixed to the mounting table 10B. The action part of the load cell contacts the foot 20.

  When a load is applied to the load cell, the action part moves relative to the load cell body. And the signal according to the movement of an action part is outputted from a load cell main part. The output signal is transmitted to the control device 60.

  The control device 60 has three arithmetic functions. First, the weight is calculated based on output signals from the four load sensors 30. Second, the bioimpedance IB is calculated based on the outputs of the first measurement electrode 43 and the second measurement electrode 44, and the body fat percentage is calculated based on the bioimpedance IB, the body weight, and other biometric information. Third, the body weight and body fat percentage are output to the display unit 50.

  The display unit 50 displays the weight and body fat percentage calculated by the control device 60. The display unit 50 is disposed between the first application electrode 41 and the second application electrode 42, that is, in front of the placement surface 15.

  The display unit 50 has an interface function for inputting biological information. That is, the measurement person can input information such as weight, age, and sex to the control device 60 through the display unit 50.

  The foot 20 is formed in a cylindrical shape. A non-slip rubber sheet is attached to the bottom surface of the foot 20. The upper surface of the pedestal 20 is a receiving portion 20A against which the action portion of the load cell hits.

  Each foot 20 is provided at each of four corners on the back side of the placement surface 15. Two front feet (front feet) support the front portion of the base 10. Two rear legs (rear legs) support the rear of the base 10. Specifically, a right front foot 21 is provided at a portion corresponding to the toe portion of the right foot, and a left front foot 22 is provided at a portion corresponding to the toe portion of the left foot. A right rear foot 23 is provided at a portion corresponding to the heel of the right foot, and a left rear foot 24 is provided at a portion corresponding to the heel of the left foot.

Each foot 20 is disposed at the following position with respect to the side surface of the base body 10A.
The right front foot 21 is disposed on the inner side of the extension surface SA of the right side surface 12 and on the inner side of the extension surface SD of the front surface 14. The left front foot 22 is disposed on the inner side of the extension surface SB of the left side surface 13 and on the inner side of the extension surface SD of the front surface 14. The right rear foot 23 is disposed on the inner side of the extension surface SA of the right side surface 12 and on the inner side of the extension surface SC of the rear surface 11. The left rear foot 24 is disposed on the inner side of the extension surface SB of the left side surface 13 and on the inner side of the extension surface SC of the rear surface 11. Here, the inside of the extended surface means that the entire foot 20 is in the region on the center side of the pedestal main body 10A from the extended surface. The extended surface of the side surface refers to an extended surface of the main surface that occupies most of the surfaces constituting the side surface. For example, when a taper is provided at a connection portion between the right side surface 12 and the bottom surface 16, this connection portion (portion corresponding to the taper) is regarded as a portion other than the main surface. Note that the extension surface SC of the rear surface 11 and the extension surface SD of the front surface 14 are not shown.

  By the way, when the right side surface 12 and the left side surface 13 of the base body 10A are inclined inward, the base 10 is easily inclined. For example, the measurer places his / her feet on the outside of the pedestal 10 or places his / her feet on the pedestal 10 with the body tilted outward with respect to the pedestal 10, that is, with the body's center of gravity placed outside the pedestal 10. The pedestal 10 tilts. If the base 10 is tilted, the measurer's feet become unstable, and the measurer loses balance. In this regard, the operation of the biological information measuring apparatus 1 having the above configuration will be described by comparing the biological information measuring apparatus 1 having the above structure and the biological information measuring apparatus 100 having the comparative structure.

FIG. 3A shows the inclination degree of the biological information measuring apparatus 100 having the comparative structure, and FIG. 3B shows the inclination degree of the biological information measuring apparatus 1 having the above structure.
In the biological information measuring apparatus 100 having the comparative structure, a part of the foot 120 is disposed outside the extended surface SE of the side surface 111 of the pedestal 110. In this structure, when the measurer places his / her foot on the outside of the pedestal 110, or when he / she places his / her foot on the pedestal 110 with the center of gravity of the body placed on the outside of the pedestal 110, the pedestal 110 is outside the Tilt around the edge of the fulcrum. Then, once the pedestal 110 starts to tilt, the side edge 118 of the pedestal 110 tilts until it contacts the ground. When tilted to such an angle, the measurer loses balance.

FIG. 3B shows the degree of inclination of the biological information measuring apparatus 1 of the present embodiment.
In the biological information measuring apparatus 1 of the present embodiment, the foot 20 is arranged on the inner side of the side extension surface.

  In the case of this structure, the pedestal 10 is tilted by placing a foot on the outside of the pedestal 10 or placing the foot on the pedestal 10 with the center of gravity of the body placed outside the pedestal 10, but Before the side edge 18 hits the ground, the bottom side edge 19 of the base body 10A contacts the ground. The inclination of the pedestal 10 at this time is smaller than the inclination of the biological information measuring device 100 having the comparative structure. Thereby, the frequency where a measurer loses balance can be controlled.

(Effect of embodiment)
According to the biological information measuring apparatus 1 of the present embodiment, the following effects can be obtained.
(1) In the biological information measuring device 1, the right front pedestal 21 and the right rear pedestal 23 are arranged on the right side surface 12 with respect to the biological information measuring device 1 that is inclined inwardly as the side surface of the pedestal main body 10A is directed downward. It arrange | positions inside extension surface SA. Further, the left front foot 22 and the left rear foot 24 are arranged on the inner side of the extended surface SB of the left side surface 13.

  When the measurer is placed on the pedestal 10, the biological information measuring device 1 may tilt. When the inclination of the biological information measuring device 1 is small, the measurer hardly loses the balance. However, when the biological information measuring device 1 is greatly inclined, the measurer loses the balance. In particular, when the side surface of the pedestal main body 10A is inclined inward, there is a high possibility that a load is applied to the outer side of the pedestal 20, and once the biological information measuring apparatus 1 is inclined, the side edge 18 of the pedestal 10 is brought to the ground. Because it tilts until it comes into contact, the measurer is likely to lose balance. In this regard, according to the above configuration, when the pedestal 10 is tilted, the bottom side edge 19 contacts the ground, so that the pedestal 10 is prevented from being largely tilted, thereby reducing the frequency with which the measurer loses balance. Further, unlike the prior art, a protrusion is not provided on the bottom surface 16 of the pedestal main body 10A to restrain the inclination of the pedestal 10, so that the vertical movement of the pedestal main body 10A is not restricted. For this reason, a body weight can be measured correctly.

  (2) In the biological information measuring device 1, the angle θ formed between the right side surface 12 and the bottom surface 16 and the angle θ formed between the left side surface 13 and the bottom surface 16 are obtuse angles. According to this configuration, when the biological information measuring apparatus 1 is viewed from above, a part of the side surface of the pedestal 10 is hidden, and the whole or part of the pedestal 20 is hidden and cannot be seen. That is, the impression that it is more compact than the actual size can be given.

  (3) In the biological information measuring apparatus 1, the electrode 40 is provided on the placement surface 15. According to this configuration, since a current can flow through the body through the electrode 40, the bioimpedance IB can be measured.

  (4) In the biological information measuring device 1, the foot mark is composed of electrodes. That is, the shape of the electrode 40 corresponds to the shape of the foot mark. When the measurer sees a shape corresponding to the shape of the foot (foot mark), he or she unconsciously places the foot on the foot mark. For this reason, it is less likely that the foot is placed at a place other than the place of the electrode 40. Thereby, it is possible to suppress the frequency at which the measurement accuracy of the body fat percentage decreases due to the contact area between the electrode 40 and the body being insufficient.

(Second Embodiment)
The biological information measuring device 1 of this embodiment is configured as a part of the biological information measuring device 1 of the first embodiment changed. For this reason, below, the detail of a different point from the biological information measuring device 1 of 1st Embodiment is demonstrated, about the structure which is common in the same embodiment, the same code | symbol is attached | subjected and the one part or all part of the description is abbreviate | omitted. .

  In the biological information measuring apparatus 1 according to the first embodiment, the positional relationship between the foot 20 and the electrode 40 is not particularly defined. However, in this embodiment, the central axis of the foot 20 is outside the center line of the electrode 40. To place.

  As shown in FIG. 4, the center axis CJ of the right front foot 21 is arranged outside the center position of the first application electrode 41 in the width direction passing through the center axis CJ of the right front foot 21. In the width direction passing through the central axis CJ of the right rear foot 23, the central axis CJ of the right rear foot 23 is disposed outside the center position of the first measurement electrode 43. Specifically, the center axis CJ of the right front foot 21 and the center axis CJ of the right rear foot 23 are center lines in the width direction of the first application electrode 41 and the first measurement electrode 43 (hereinafter referred to as “first center”). It is arranged outside the line C1 "). The first center line C1 is a line passing through the center of gravity of the first application electrode 41 and the center of gravity of the first measurement electrode 43.

  Similarly, the center axis CJ of the left front foot 22 is disposed outside the center position of the second application electrode 42 in the width direction passing through the center axis CJ of the left front foot 22. In the width direction passing through the central axis CJ of the left rear foot 24, the central axis CJ of the left rear foot 24 is arranged outside the center position of the second measurement electrode 44. Specifically, the center axis CJ of the left front foot 22 and the center axis CJ of the left rear foot 24 are center lines in the width direction of the second application electrode 42 and the second measurement electrode 44 (hereinafter referred to as “second center”). It is arranged outside the line C2 "). The second center line C2 is a line passing through the center of gravity of the second application electrode 42 and the center of gravity of the second measurement electrode 44.

  By the way, when the right side surface 12 and the left side surface 13 of the pedestal main body 10 </ b> A are inclined inward, the pedestal is in a state in which the measurer puts his / her feet on the outside of the pedestal 10 or places the center of gravity of the body outside the pedestal 10. The pedestal 10 may be tilted by placing a foot on it. On the other hand, in 1st Embodiment, the foot 20 is arrange | positioned inside the extended surface of a side surface. Thereby, the inclination of the base 10 is once stopped. However, if the pedestal 20 is brought too close to the center of the pedestal 10, the pedestal 10 tilts even if a load is appropriately applied to the place where the foot corresponding to the electrode 40 is placed. In this regard, the operation of the biological information measuring apparatus 1 having the above configuration will be described by comparing the biological information measuring apparatus 1 having the above structure with the biological information measuring apparatus 200 having the comparative structure.

  FIG. 5A shows a state where one leg is placed on the placement surface of the biological information measuring device 200 having the comparative structure, and FIG. 5B shows the placement surface 15 of the biological information measuring device 1 having the above structure. The state when one foot is placed on is shown.

  As shown in FIG. 5A, in the biological information measuring apparatus 200 having the comparative structure, the center axis CJ of the right front foot 221 and the center axis CJ of the right rear foot 223 are from the first center line C1 of the electrode 40. Is also placed inside. Similarly, the center axis CJ of the left front foot 222 and the center axis CJ of the left rear foot 224 are arranged on the inner side of the second center line C2 of the electrode 40. In the case of this structure, when one leg is placed at a position corresponding to the second measurement electrode 244, the load of the measurer is outside the center axis CJ of the left front foot 222 and the center axis CJ of the left rear foot 224. As it is added, the pedestal 210 tilts.

  On the other hand, in the biological information measuring apparatus 1 having the above structure, the center axis CJ of each foot 20 is disposed outside the center line of the corresponding electrode 40. For this reason, when one foot is placed at a position corresponding to the second measurement electrode 44, the load of the measurer is applied on the inner side of the center axis CJ of the left rear foot 24, so that the pedestal as shown in FIG. 10 hardly tilts.

(Effect of embodiment)
According to the biological information measuring apparatus 1 of the present embodiment, the following effects can be obtained in addition to the effects (1) to (4) of the first embodiment.

  (5) In the biological information measuring device 1, the central axis CJ of the foot 20 is disposed outside the center position (center of gravity) of the electrode 40 indicating the foot mark in the width direction passing through the central axis CJ of the foot 20. ing. According to this configuration, since the load applied to the pedestal 10 is suppressed from being applied to the outside of the center axis CJ of the pedestal 20, the biological information measuring device 1 is suppressed from being inclined.

(Third embodiment)
The biological information measuring device 1 of this embodiment is configured as a part of the biological information measuring device 1 of the first embodiment changed. For this reason, below, the detail of a different point from the biological information measuring device 1 of 1st Embodiment is demonstrated, about the structure which is common in the same embodiment, the same code | symbol is attached | subjected and the one part or all part of the description is abbreviate | omitted. .

  In the first embodiment, the four foots 20 are arranged on the inner side with respect to the extended surface of the side surface of the base body 10A. On the other hand, in this embodiment, the front pedestal 20 is arranged inside the extended surface of the side surface of the pedestal main body 10A, and the rear pedestal 20 is set to the extended surface of the side surface of the pedestal main body 10A. Arranged outside.

  As shown in FIG. 6, the mounting table 10B is formed in a trapezoid whose front side is longer than the rear side. The pedestal main body 10 </ b> A is formed to be narrowed toward the bottom surface 16 in a side view. By setting it as such a shape, the base 10 is made into the external appearance which gives a compact impression.

Each foot 20 is arranged as follows.
The right front foot 21 is disposed on the inner side of the extension surface SA of the right side surface 12 and on the inner side of the extension surface SD of the front surface 14. The center axis CJ of the right front foot 21 is disposed on the inner side of the center line in the width direction of the first application electrode 41 (hereinafter, “third center line C3”). Note that the third center line C3 is a line connecting points that are equidistant from both sides in the straight portions of the sides facing each other in the width direction of the first application electrode 41.

  The left front foot 22 is disposed on the inner side of the extension surface SB of the left side surface 13 and on the inner side of the extension surface SD of the front surface 14. The central axis CJ of the left front foot 22 is disposed on the inner side of the center line in the width direction of the second application electrode 42 (hereinafter, “fourth center line C4”). The fourth center line C4 is a line obtained by connecting points that are equidistant from both sides in the straight line portions of the sides facing each other in the width direction of the second application electrode 42.

  A part of the right rear foot 23 is disposed outside the extended surface SA of the right side surface 12, and the entire right rear foot 23 is disposed inside the extended surface SC of the rear surface 11. Further, the center axis CJ of the right rear foot 23 is arranged outside the center line in the width direction of the first measurement electrode 43 (hereinafter, “fifth center line C5”).

It matches the size. In this case, the mounting table 10B has a trapezoidal shape as shown in FIG. In the case of such a structure, it is difficult to arrange the foot 20 as in the second embodiment. That is, since the space between the center line of the electrode 40 and the extended surface of the side surface of the pedestal main body 10A becomes small, it is difficult to arrange the foot 20 in this space as in the second embodiment. If the pedestal 20 is provided in this space, it is necessary to reduce the diameter of the pedestal 20, and in this case, it becomes impossible to withstand the load.

  Therefore, as described above, the tilt of the pedestal 10 is restrained by the front pedestal 20, and the stability of the pedestal 10 is secured by the rear pedestal 20. That is, when the pedestal 10 is tilted by disposing the right front pedestal 21 inside the extension surface SA of the right side 12 and the left front pedestal 22 inside the extension surface SB of the left side 13, the pedestal 10 is inclined. It is set as the structure where the bottom face side edge 19 of 10 contacts. This suppresses further tilting. Further, the distance between the right rear foot 23 and the left rear foot 24 is increased. That is, the center axis CJ of the right rear foot 23 is disposed outside the fifth center line C5, and the center axis CJ of the left rear foot 24 is disposed outside the sixth center line C6. This makes it difficult for the pedestal 10 to tilt.

That is, when all the four legs 20 are arranged inside the extended surface of the side surface of the pedestal main body 10A, the distance between the legs 20 is larger than that of the comparison device in which the four legs 20 are arranged in the same manner. Since it becomes narrower, it is easier to tilt than the comparison device. Therefore, as described above, by arranging the two foot 20 in front of the placement surface 15 on the inner side of the extended surface of the side surface, even if the pedestal 10 is inclined once, it is inclined further. Suppress. In addition, the center axis CJ of the two foots 20 at the rear is arranged outside the center line of the electrode 40 corresponding to the foot 20.
