9 and 10 will be described in detail with respect to the body composition measuring method for the body composition measuring device of the present invention.

The body composition analyzer of the present invention is set to the weight measuring mode in which the device is in an initial state when the power source 18 is turned on, and the weight is measured when the subject is placed on the display unit on the footrest 2a of the scale (S1). .

The controller 13 detects fine movements on the scale of the scale and the deviation of the subject to determine whether normal weight measurement is performed (S2). When it is determined that normal weight measurement is performed, the controller 14 stores the measured weight data. ) And output through the display device 16 (S3). If the control device 13 determines that the normal weight measurement is not made, the controller 13 moves back to the initial weight measurement mode.

When the weight measurement is finished, the user is guided through a display device 16 such as a speaker or a screen to input personal information of the subject, and the subject inputs personal information such as gender, age, height, etc. according to the guidance. Input using 15) (S4).

When the personal information is input, the control device 13 determines whether the personal information is correctly input (S5), and simultaneously determines whether the change in the weight of the subject is in the error range in the process of inputting the personal information (S6). .

If the personal information is correctly input and it is determined that the change in the weight of the subject is in the error range, the control device 13 controls the electrode moving device 21 to be driven (S7).

The sole electrode located at the lower part of the footrest 2a protrudes upward by the driving of the electrode moving device 21 to contact the center recess of the sole of the subject.

Subsequently, if the weight of the subject is within the error range during the personal information input process and there is an error in the input of the personal information, the control device 13 moves to step S4 to control and input the personal information. When the personal information is correctly input but the change in the weight of the subject falls outside the error range, the controller determines that the subject has moved away from the scaffold 2 and moves to step S1.

On the other hand, when the electrode mover 21 is driven in step S7, the guide unit 16 guides the display device 16 so that the body of the subject can be precisely contacted with the sole electrode and the palm electrode position (S8). When the handles 8a and 8b are wrapped, the control device 13 determines whether each electrode has a poor contact from the body of the subject (S9).

If there is no contact failure of each electrode, the measured impedance is measured (S10).

The impedance measurement is carried out by the current of the palm electrodes 10a, 10b, 22a, 22b and the sole electrodes 10c, 10d, 22c, and 22d selected by the electrode exchanger 19. The current is supplied through the supply device 11 and the voltage of the electrode section is measured by the voltage measuring device 12 and calculated.

In the process of measuring the impedance, the control device 13 determines (S11) whether a poor contact or separation of the electrode occurs. If there is no detachment or poor contact of the electrodes, the controller 13 calculates the measured body weight, body fat mass, body fat percentage, obesity degree, and body mass index by combining the measured impedance data with the personal information of the subject. The basic metabolic amount is calculated, and the result is stored in the storage device 14 and output through the display device 16 (S12).

If separation of the electrode or contact failure occurs in step S11, the process moves to step S7 to allow the impedance to be measured again.

Subsequently, after the impedance measurement is completed, when the subject comes down on the scale of the scale, the electrode moving device 21 is turned off, and the sole electrode is lowered to the bottom of the scale of the scale, and the body composition measuring instrument returns to the initial state.

In the present invention, after the weight is measured, the sole electrodes 10c, 10d, 22c, and 22d, which are located at the lower part of the scale of the scale, automatically protrude to contact the center recess of the sole of the subject. It is possible to prevent the poor contact of the electrode by the foreign matter to increase the measurement accuracy of the human impedance, it is possible to obtain the effect of improving the hygiene state.
