When the screw shaft drive servomotor 64 is rotated, the slider 54 slides on the guide members 52a and 52b according to the rotation of the screw shaft 48 due to the action of the screw groove between the screw shaft 48 and the ball nut 50. In this embodiment, the screw shaft drive servo motor control unit 66 described later controls the screw shaft drive servo motor 64 so that the screw shaft drive servo motor 64 is always driven at a constant rotation speed. As a result, the slider 54 always slides on the screw shaft 48 at a constant speed.

A control box 68 is provided on the rear side of the base 12. Control box 68
As shown in FIG. 4, as shown in FIG. 4, the motor control unit 70 for controlling the rotation of the servo motor 18 for rotating the rotation plate 20 and the operation of the screw shaft driving servo motor 64 of the linear movement module 30 are controlled.

In the control box 68, a DC power supply (not shown) is installed in addition to the operation sequencer 71 and the like, and supplies an operation voltage to each device.

[0034] Next, a method for measuring the type by type measuring device 10. As shown in FIG. 5, the subject first stands upright on the rotating plate 20 with the pair of foot-shaped fixing devices 20a, 20a stepped on. At this time, the subject is oriented so that the front of the body faces directly in front of the line connecting the light emitter 32 and the light receiver 34 of the measuring sensor 30, that is, for example, the base of one shoulder and the base of the other shoulder. Must be positioned so as to be substantially parallel to the line connecting the light emitter 32 and the light receiver 34. This is because when the lateral diameter and the thickness of the body are measured from the oblique direction of the body, errors tend to occur in the measurement results. At this time, both sides of the subject must be located between the light emitter 32 and the light receiver 34. FIG. 5 is a side view showing one step of the measuring operation of the body type measuring device.

[0035] Thereafter, the operator presses the measurement start switch 72, the measuring operation is started. First,
Screw axis drive servo motor 64 of linear movement module 38
Is driven at a constant rotational speed, the measuring sensor 30 moves at a constant moving speed in the direction of arrow A in FIG. 5, and scans from the side of the subject.

At this time, from each of the optical sensors 30a of the measuring sensor 30, a feedback signal indicating whether or not the body part of the person to be measured exists is transmitted via the measuring sensor control unit 36 at regular time intervals. The operation signal is converted into a detection signal and input to the operation sequencer 71. The feedback signal of the optical sensor 30a is "o" when there is no obstacle.
The detection signal represented by “n” and, when there is an obstacle, “off” is set so as to be input from the measuring sensor control unit 36.

The operation sequencer 71 has a built-in buffer, and the detection signal input from the optical sensor 30a is, for example, as shown in FIG. The data is stored in the data group d1 in a format having an optical sensor number and a detection time so that it can be grasped. In this embodiment, an optical sensor number "1" is given to the optical sensor 30a located at the lowermost position, and an integer 1 is added to the optical sensor number every time the optical sensor 30a goes up by one stage to represent each optical sensor 30a. I have.
FIG. 6 is a conceptual diagram showing a storage state of a data group stored in the buffer.

After the linear movement module 38 has finished moving in the direction of arrow A and has finished scanning the side surface of the person to be measured, the rotary plate 20 is rotated by 90 degrees by the servo motor 18 as shown in FIG. In this manner, the orientation of the subject is changed such that the line connecting the front of the subject and the corresponding back surface is parallel to the line connecting the projector 32 and the light receiver 34.

[0039] After the orientation of the subject is changed, constant and when performing a scan from the side surface side of the subject, and the moving direction reversed, measuring sensor 30 is the arrow B direction in FIG. 7 And scans from the front side of the subject.
Also at this time, each optical sensor 3 of the measuring sensor 30 is used.
From 0a, at regular time intervals, a feedback signal indicating whether or not the body part of the subject exists is converted into a detection signal via the measuring sensor control unit 36 and input to the operation sequencer 71. . The data group d2 (not shown) is stored in the buffer in the same format as the data group d1.

After the linear movement module 38 has finished moving in the direction of arrow B and has finished scanning the front part of the subject, the data groups d1 and d2 stored in the buffer
Is sent to the arithmetic processing section 74a of the arithmetic processing device 74 and used for arithmetic processing.

In the arithmetic processing section 74a, the data group d1
And d2 are the moving speed of the linear moving module 38,
Based on the values relating to the detection time stored in the data groups d1 and d2, for example, as shown in FIG. 8, it is determined at which position in the horizontal position the detection result of each optical sensor 30a is the detection result. For the sake of illustration, it is converted into data groups d1 'and d2' (not shown in FIG. 8) having a value represented at the horizontal position. FIG. 8 is a conceptual diagram showing a storage state of the converted data group. As a result, the data groups d1 and d2 become a data group representing a horizontal position, and the height of the detection width of the measuring sensor 30 and the height of the subject within the flat area including the width of the movement width of the linear movement module 38 are measured. The distribution status of the body can be grasped. That is, the data group d1 'represents the distribution state of the body from the side of the subject, and the data group d2' represents the distribution state of the body from the front of the subject.

In this embodiment, the moving speed of the linear moving module 38 and the data groups d1 and d2
Based on the value related to the detection time stored in, the detection result of each optical sensor 30a was determined to indicate at which position in the horizontal position the detection result was, but not limited to this.
The linear movement module 38 is provided with a device such as an encoder capable of acquiring a value relating to the position, and the detection result of each optical sensor 30a is stored in a buffer at intervals of a predetermined distance.
The configuration may be such that the distribution state of the body of the subject in a flat area having a width corresponding to the movement width of the linear movement module 38 is grasped.

The arithmetic processing unit 74a outputs the data group d
Regarding 2 ′, the detection signal input for each optical sensor number, that is, for each identical optical sensor 30a is scanned to obtain the switching position and the number of times of switching of the detection signals “on” and “off”.

[0044] Further, the arithmetic processing unit 74a uses the switching Ri number obtained from the above-described process, calculates the crotch height of the subject. The calculation procedure is as follows. First, the arithmetic processing unit 74a performs a search from a detection result having a low value of the optical sensor number, and determines a boundary position between a light receiving range generated by blocking the measurement site of the subject and a range in which light cannot be received. When the number has been switched from four to two, the first changed optical sensor number is obtained. The number of the switched boundary positions is 4
Means that the lower part of the subject's crotch is measured, and when the number of boundary positions is 2, this means that the upper part of the subject's crotch is measured. ing.
Then, the arithmetic processing unit 74a calculates the crotch height of the person to be measured by integrating the arrangement intervals of the optical sensors 30a and the optical sensor numbers in the previous search operation. For example, in this embodiment, since the arrangement interval of the optical sensors is 20 mm, when the optical sensor number is 39, the crotch height is 780 mm.

[0045] Then, the arithmetic processing unit 74a, in the foregoing step, the detection signal of the low light sensor number of a value from the optical sensor numbers used to crotch height, set as the detection results on leg portion of the subject, The difference between the switching position of the detection signal “on” and “off” detected first and the switching position of the detection signal “on” and “off” detected next is used as the lateral diameter of one leg. . In addition, regarding the detection signal having the optical sensor number higher than the optical sensor number obtained in the above-described process, the switching position of the first detected detection signal “on” or “off” and the last detected signal The difference between the detected signal “on” and the “off” switching position is used as the lateral diameter of the body at the measurement location.

[0046] Subsequently, the arithmetic processing unit 74a in order to obtain a value for the thickness of the subject, the data groups d1 ', each photosensor numbers each, i.e. the same optical sensor 3
The detection signal input every 0a is scanned. Then, the switching position and the number of times of switching of the detection signals “on” and “off” are acquired, and the detection signals “on” and “o” that are detected first are obtained.
ff ”and the next detected detection signal“ o ”.
The difference between the switching position of “n” and “off” is used as the thickness of the subject.

The values of the lateral diameter and the thickness of the subject obtained by the scanning / computing process of the computing unit 74a are respectively used to obtain the perimeter of the subject at the measurement site.
Used as the major and minor axes of the ellipse. This is an effective method for approximately calculating the perimeter of a measurement site of a person to be measured since the horizontal cross section of each part of the human body can be regarded as a substantially elliptical shape.

[0048] Hereinafter, using the values of transverse diameter and thickness of the subject, determine the perimeter of the ellipse, the result, one method of obtaining the arithmetic processing unit 74a to perimeter at the measurement site of the measurement subject explain

Firstly, in the formula 2 derived from Equation 1 shown below is an equation of an ellipse, half of the major axis value a and a minor axis half of the value b of the transverse diameter and thickness of the subject Apply the halved value.

[0050]

(Equation 1)

[0051]

(Equation 2)

The arithmetic processing unit 74a sets the variable x of the mathematical expression 2 in a very small increment in a range from a value -a obtained by making the value a of the half of the major axis negative to -a of the value a of the half axis. By giving a variable x according to and obtaining a value y, a plurality of points are defined on the xy coordinates, and an elliptical shape is obtained. In this embodiment, the value of the step is a / 1
0000 was used.

[0053] Then, the arithmetic processing unit 74a is the absolute distance calculates for each point adjacent defined on the xy coordinate, by integrating the value, to calculate the perimeter of the ellipse, and as a result, The perimeter at the measurement site of the subject is determined.

Further, when the cross-sectional area at the measurement site of the person to be measured is obtained, it can be easily obtained by obtaining the area of the ellipse according to Equation 3.

[0055]

(Equation 3)

[0056] Then, perimeter and cross-sectional area of the portion of the measuring body the subject calculated by the integrated measuring method described above, is displayed on the display unit 74b. In this case, regarding the display of the measurement results, all the measurement sites of the measured body may be displayed, or the measurement results of only the measurement sites at an arbitrary height of the body, for example, the thigh, may be displayed. It may be displayed. Further, the measurement result may be displayed not only on the display unit 74b but also by providing an output device such as a printer in the arithmetic processing unit 74 and printing it on paper, for example. A device may be provided to store and save.

[0057] Here, a method of obtaining the perimeter of the ellipse described is an example, not limited to this, for example, a method of calculating a circle inscribed in a square, the transverse diameter and thickness of the subject The perimeter and area of the ellipse may be determined by applying the value to the long side or short side of a rectangle such as a rectangle. Further, when the major axis and the minor axis of the ellipse have the same length, the shape of the measurement site is circular. Therefore, the circumference and / or area thereof may be determined as appropriate. Further, an average error may be calculated from the dimensions of each part actually measured by a measure or the like, and the arithmetic processing unit 74a may correct the dimensions.
