Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fat amount measuring device that measures the amount of fat on the skin surface of a human body by measuring the amount of fat transferred to a fat transfer tape.

The fat mass measuring device is composed of a cassette and a measuring device, which are separate from each other.

The cassette consists of a raw tape reel that winds a plastic tape made of transparent or semi-transparent material with a thickness of approximately 0.1 mm that has one side roughened and matted, and a take-up reel that winds up the used tape. The tape pulled out from the raw tape reel is passed over a transparent guide plate facing the outside of the case or a guide plate with a mirrored outer surface and wound around a take-up reel.

On the other hand, the measuring device has a light emitting part such as a light bulb in its body.
A light receiving section consisting of a photoelectric conversion element such as CdS, a circuit for amplifying and controlling the signal from the light receiving section, and a display section showing the amount of fat are provided.

Therefore, in order to use the fat amount measuring device, the person holds the cassette and presses the matte side of the tape directly against the skin surface to adhere or transfer fat there. The tape surface onto which the fat has been transferred in this manner is set in a measuring device, and the light from the light emitting section is irradiated from the rear or front surface of the transfer tape. When the light emitting section is located on the rear surface of the transfer tape, the amount of transmitted light is detected by the light receiving section, and when it is located on the front surface, the amount of reflected light of the light that has once passed through the transfer tape is detected by the light receiving section. The amount of electricity corresponding to the amount of light received is measured and the amount of fat is finally displayed on the display section. Since the transmittance of light changes depending on the amount of fat attached to the transfer tape, the amount of transmitted light will change depending on the amount of fat.

However, with conventional fat measurement devices, fat is attached to a predetermined area of the tape exposed from the cassette, and the entire attached surface is irradiated with light to measure the amount of transmitted or reflected light. Since the amount of fat was measured, the value of the amount of fat was the average value for the entire fat attachment surface. Therefore, even though the amount of fat secreted at each site on the skin surface is different, an accurate value cannot be obtained from the average amount of fat.

In view of the above-mentioned circumstances, the present invention aims to provide a fat amount measuring device that can obtain an accurate secretion state of skin fat amount by knowing the distribution of the amount of adhering fat on the tape.

Embodiments of the present invention will be further described below with reference to the drawings. FIG. 1 and FIG. 2 are schematic illustrations of a fat mass measuring device.

The case 3 has a substantially flat rectangular parallelepiped shape, and one longitudinal side of the case 3 forms a tapered part 3a that gradually tapers in both width and thickness toward one end. A window 4 is provided on the flat rectangular surface at the tip of the tapered portion 3a, and a part of the guide plate 5 protrudes from the window 4, and the case 3
When an external force is applied to the guide plate 5 by pressing it from the inside with a leaf spring 6, the guide plate 5 is pulled into the case 3. The guide plate 5 is made of a transparent member that can sufficiently transmit light from the outside. Case 3
A raw tape reel 7 and a take-up reel 8 are each rotatably supported inside the case, and the take-up reel 8 is rotated by a knob 9 protruding from the outside of the case. The tape 10 is pulled out from the raw tape reel 7 and wound onto the take-up reel 8 through the outer surface of the protrusion of the guide plate 5. A recess 11 is provided on the lower surface of the case assembly 2 of the case 3. This recess 11 is a space into which a light projecting section 12 provided in the measuring instrument B is inserted, and a filter 13 is provided on the front surface of the recess 11 to diffuse light. The diffused light passes through the guide plate 5 and is irradiated onto the tape 10 as uniform light, which serves to reduce measurement errors.

This sampling command signal is input to the measurement circuit 24, and the amount of fat deposited on a certain minute area of the tape to be measured corresponding to the location where the light receiving block 16 is located is measured.
Immediately after this measurement is completed and the next sampling command signal is output from the measurement control circuit 23, a storage signal is output from the measurement control circuit 23 to the storage circuit 25, and the storage circuit 25 to which this storage signal has been input is Remember the results. The above operation is repeated every time the actuation signal and the sampling command signal are output at fixed time intervals, and when the light receiving block 16 reaches the position of the sensor 30 on the guide rod 17, a stop signal is output, and this signal is The input motor control circuit 22 stops the motor 19 and also stops the light receiving block 16. A plurality of measurement results obtained by sequentially measuring portions of the tape 10 at fixed time intervals until the light receiving block 16 stops are all stored and held in the memory circuit 25. Thereafter, the light receiving block 16 is returned to its initial position by the force of a spring 31 provided on the opposite side of the wire 18.
