BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronically controlled automatic electrode device for measuring internal fat using an electronic control device.

[0002]

2. Description of the Related Art The evaluation of body composition is used as an important information for determining an index of health and an effect of physical activity.
Body composition has been evaluated by various methods such as a density method based on underwater weighing method, a water method, and a potassium method. However, many of them require expensive equipment and complicated procedures for measurement, and thus lack practicability and economy. Therefore, although there are some problems such as selection of measurement site, validity of measurement, objectivity and reproducibility, a simple method of estimating from the density method by subcutaneous fat thickness using a caliper is adopted.

On the other hand, recently, a weak electricity (800
From the resistance (impedance) of flowing μA),
BI method (Bioelectrical) for estimating body composition
Impedance Analysis) has been developed. This method has an advantage that it can be easily applied to non-healthy persons regardless of age and sex.

Specifically, as a technique in such a field, there has been a technique described in Japanese Patent Laid-Open No. 62-169023, for example. That is, (1) a weak AC current is passed through the electrode, the electrode for detection is taken out and converted into the number of ohms, and the obtained value is arithmetically processed to electrically measure the weight of adipose tissue in the body. In order to do so, a foot electrode to be brought into contact with the subject's foot is arranged.

(2) For the same purpose, a hand electrode to be brought into contact with the hand of the person to be measured is arranged.

[0006]

However, in the above-mentioned (1) in which the electrode for the foot to be brought into contact with the foot of the person to be measured is arranged, the socks are taken off to expose the soles of the feet on the step during the measurement. You have to ride it, which is troublesome. Especially,
Women often feel uncomfortable with taking off their socks, especially in the case of special socks such as pantyhose.

Further, the above-mentioned method (2) of arranging the hand electrode to be brought into contact with the hand of the person to be measured has been conventionally performed in the following procedure. Hereinafter, the measuring method by the BI method for measuring the body fat as well as the height and weight will be described.
6 and 7 are explanatory views of a conventional measurement procedure, and FIG. 8 is a flowchart showing the measurement procedure.

(1) First, as shown in FIG. 6A, the person to be measured inputs his or her age and sex into the controller 1 (step S1). (2) Next, as shown in FIG. 6 (b), take off the shoes and ride on the step 2 of the height / weight scale to measure the height and weight (steps S2 and S3). (3) Next, when the measurement of height and weight is completed,
As shown in (c), the operator descends from the step 2 of the height / weight scale to measure the body fat (step S4).

(4) Next, as shown in FIG. 6 (d), sit down on the chair 3 and apply a thin layer of conductive cream to four places on both wrists and the back (hereinafter referred to as the wrist) (step). S
5). (5) Next, as shown in FIG. 6E, the electrodes 4 are attached to the four locations (step S6). (6) Next, as shown in FIG. 6 (f), the sides are separated (step S7).

(7) Next, as shown in FIG.
When the preparation for measuring the body fat is completed, the foot switch 5 at the foot is pressed to turn on the body fat measurement system (step S8). (8) Next, as shown in FIG. 7B, the body fat is measured without moving while keeping the armpits apart (step S
9).

(9) Next, as shown in FIG. 7 (c), when the measurement of the body fat is completed, the electrodes 4 at the four places on the wrist where the conductive cream is applied are removed (step S10). (10) Next, as shown in FIG. 7D, since the printer 6 of the controller 1 outputs the paper 6 on which the result is printed, the paper 6 is taken. (11) Next, as shown in FIG. 7 (e), the part of the measurement subject's wrist where the electrode 4 is attached, that is, the part where the conductive cream is attached is washed with water or a tissue containing ethanol. Wiping with 7 removes the conductive cream (step S11).

Thus, in the conventional measuring method, in particular,
When measuring the body fat, it is necessary to apply a conductive cream to the wrist of the person to be measured and attach the electrode to it, which is troublesome and it is difficult to remove the conductive cream that has adhered. . In addition, height as described above

An electrode device 21 is provided at the lower end of the lifting rod 20. This electrode device 21 includes a lifting rod 20.
An electrode device body 22 is pivotally supported by a pivot shaft 24 at the lower end of the electrode device 21, and the electrode device 21 is tiltable with respect to the elevating rod 20. A pair of electrodes 23a and 23b are arranged on the lower surface of the electrode device body 22 with a predetermined distance therebetween.
