In addition, a plurality of wheels 7 are provided on the peripheral edge of the lower surface of the measuring table 2. All the rotation center axes of the wheels 7 are set in a direction orthogonal to the rotation center axis of the motor 6, and the measurement table 2 is rotatably supported when the measurement table 2 is driven to rotate by the motor 6. It is like that. As the distance meter 3, for example, a device that measures a distance using a laser beam, an ultrasonic wave, or the like can be used.

  In addition, a frame 8 and an airbag 9 for fixing the body of the person to be measured P are provided on the measurement table 2. The frame 8 and the airbag 9 are divided so that the measurement subject P can get on and off the measurement table 2. The person to be measured P can get on and off the measuring table 2 from the entrance 10 formed at the location where the frame 8 and the airbag 9 are divided.

  The air bag 9 is a fixing means that is fixed inside the frame 8 so that the body of the person to be measured P does not move by inflating and sandwiching the body of the person to be measured P by introducing air into the inside. The frame 8 is provided with a regulating wall 8 a so that the airbag 9 is inflated only toward the inside of the frame 8, that is, toward the center of the measuring table 2. The frame 8 and the airbag 9 are set to a height that does not hinder measurement by the distance meter 3 and imaging by the camera 4.

  Moreover, the body measuring apparatus 1 in this embodiment is provided with the central processing unit 11 for controlling each part or performing arithmetic processing as shown in FIG. The central processing unit 11 images the measurement subject P on the measurement table 2 by the camera 4 in order to determine the measurement position of the body surface of the measurement subject P, and adjusts the height based on the image captured by the camera 4. The height of the distance meter 3 is adjusted by means 12. The height adjusting means 12 adjusts the height of the distance meter 3 and the camera 4 in order to match the measurement position of the distance meter 3 with the measurement position on the body surface of the person P to be measured.

  In the present embodiment, the height adjustment is performed by measuring the position of the umbilicus as the measurement position of the person to be measured P from the image captured by the camera 4, and the measurement position of the distance meter 3 is the position of the umbilicus of the person to be measured P. The height of the distance meter 3 and the camera 4 is automatically adjusted so as to match. The central processing unit 11 displays the measurement position of the body surface measured by the distance meter 3 together with the image captured by the camera 4 on the monitor 5, so that the person to be measured P himself / herself measures the height of the distance meter 3 and the camera 4. It is also possible to adjust the height of the measurement position of the person P to be measured.

Next, abdominal circumference measurement by the body measuring apparatus 1 having the above-described configuration will be described.

Inflate, and fix the person to be measured P on the measurement table 2 so that the body does not move. The central processing unit 11 analyzes the image captured by the camera 4 to detect the position of the umbilicus of the person P to be measured, and automatically adjusts the height of the distance meter 3 by the height adjusting means 12.

  Next, the central processing unit 11 operates the motor 6 to rotate the measuring table 2 once. At this time, the central processing unit 11 measures the distance to the body surface of the person P to be measured on the rotating measuring table 2 by the distance meter 3 for one round. Then, the central processing unit 11 calculates the circumference of the measurement position on the body surface of the person to be measured P, that is, the waist circumference around the navel. The central processing unit 11 displays this measurement result on the monitor 5. The central processing unit 11 may be configured to transmit the measurement result to a device such as another computer through a communication network (not shown) and record it.

  When the measurement is completed, the central processing unit 11 operates the air bag 9 to deflate it, so that the person to be measured P can get off the measuring table 2. The central processing unit 11 is configured to display on the monitor 5 or issue a warning sound when the airbag 9 is inflated or deflated, or when the measuring table 2 rotates. It is also possible to do.

  Next, another embodiment of the body measuring apparatus of the present invention will be described. FIG. 5 is a plan view showing another embodiment of the body measuring apparatus of the present invention, and FIG. 6 is a front view of FIG.

  The body measuring device 20 shown in FIGS. 5 and 6 has a configuration in which a chair 21 whose height can be adjusted is provided at the center of the measuring table 2 in place of the frame 8 and the airbag 9 of the body measuring device 1 described above. In this configuration, by adjusting the height of the chair 21 on the measurement table 2, the measurement position by the distance meter 3 can be adjusted based on the image captured by the camera 4. The height of the chair 21 can be adjusted automatically or manually as with the distance meter 3 and the camera 4 described above. Moreover, it can replace with the chair 21 and can also be set as the structure which can adjust the height of the distance meter 3 and the camera 4. FIG.

  As described above, according to the body measuring devices 1 and 20, the measurement position on the body surface of the person P to be measured on the measurement table 2 is adjusted by the height adjusting means 12, and then the measurement table 2 is rotated. Since the abdominal circumference which is the circumference of the measurement position on the body surface is calculated by measuring the distance to the body surface of the person to be measured P, it is only necessary to rotate the measuring table 2 at the time of measurement, and the cost is reduced by a simple configuration. An installable device is obtained.

  Further, the body measuring devices 1 and 20 have the monitor 5 that displays the measurement position of the body surface measured by the distance meter 3 together with the image captured by the camera 4, so that the body surface displayed together with the captured image is displayed. It is possible to adjust the measurement position while looking at the measurement position, and it is also possible to adjust the measurement position more easily and accurately with the help of a human eye.

  Moreover, since the body measuring apparatus 1 has the airbag 9 which fixes the to-be-measured person P so that a body may not move on the measurement stand 2, the body of the to-be-measured person P is rotated by the measurement stand 2 rotating at the time of a measurement. It is possible to prevent movement and perform more accurate measurement. In particular, in the body measuring apparatus 1, since the airbag 9 is inflated on the measurement table 2 and pinches the body of the measurement subject P, the measurement subject P is riding on the measurement table 2 in any position and orientation. Even in this case, the body of the person to be measured P can be held and stably fixed by the bulging of the airbag 9, and more accurate measurement can be performed. In addition, it is possible to adopt a configuration in which the belt 9 is fixed to the frame 8 instead of the airbag 9, or in the case of the body measuring device 20, a configuration in which the seat 21 is fixed to the chair 21.

  The body measurement apparatus of the present invention is useful as an apparatus for automatically performing body measurements such as abdominal circumference and chest circumference.
