提供することを目的としている。When determining the compatibility between the bare skin of the face and cosmetics, it is necessary to measure the amount of sebum secreted together with the amount of skin moisture, as shown in JP-A-2-268738. The amount of sebum secretion is described in JP-A-54-15808.
As shown in Japanese Patent Laid-Open No. 6, it can be measured by pressing a measurement medium whose light transmittance changes when sebum adheres against the skin surface and detecting the difference in transmittance before and after the sebum adheres. Therefore,
When the skin water content and the sebum secretion amount are measured together, it is necessary to prepare an independent skin water content measurement device in addition to the sebum secretion amount measurement device. In addition, for the purpose of measuring the amount of skin moisture, the subject is forced to perform a treatment in which the comb-shaped electrode is pressed against the skin separately from the sebum collection, which makes the test troublesome for the subject and the operation for the subject. It's easy to make a mistake. When designing a skin diagnostic device, sebum and water, 2
Automating the operation of different types of sensor heads complicates the mechanism and control. It is an object of the present invention to provide a skin moisture measuring device capable of measuring a skin moisture amount in parallel with a sebum secretion amount by a single treatment of a person to be measured using the sebum secretion amount measuring device. I am trying.

ることが望ましい。In the skin moisture measuring device of the present invention, the measuring medium is pressed against the skin to adhere sebum to the surface of the measuring medium. The collected sebum contains water corresponding to the amount of skin water, and this water also affects the light transmittance of the measurement medium. For example, the transmittance is slightly increased as compared with the case of only sebum. Then, when the sebum adhesion area of the measurement medium is dried, the amount of water lost from the adhered sebum, the transmittance of the sebum adhesion area of the measurement medium changes, and finally only the sebum excluding the effect of water. Converge to a value. Therefore, the amount of water contained in the sebum on the measurement medium is estimated by measuring the amount of change in the amount of transmitted light or the transmittance before and after drying or in the process thereof. However, as a result of the experiment, "the amount of change in permeability decreases when the amount of sebum secretion is large even when the amount of water is equal" is obtained. Therefore, the amount of sebum secretion, that is, the absolute level of permeability is combined to determine the amount of water. Is desirable. In addition, through the experiment, when the measurement medium was forcibly dried, the measurement time was significantly shortened compared to the case of waiting for the natural drying, and the variation of the measurement value due to the ambient temperature and humidity was small. It is desirable to forcibly dry the sebum-attached surface by a method that can avoid the influence of changes in the amount of received light on the measurement.

Collect sebum. Tape 12 after collection
The sebum adhesion area of the light source element 1 is sent to the measuring unit 10
5 and the light receiving element 17 are positioned to face each other. In this state, the determination unit 26 takes in the initial value (mV) of the transmitted light amount from the detection circuit 25. Then, the exhaust fan 18 is immediately activated, and air at room temperature is blown to the sebum adhered area to forcibly dry it. After 30 seconds, the determination unit 26 again takes in the elapsed value (mV) of the transmitted light amount from the detection circuit 25 and stops the exhaust fan 18. The determination unit 26 subtracts the initial value from the elapsed value to calculate the change amount (mV) of the transmitted light amount. Then, as shown in FIG. 2, the sebum secretion amount is determined based on the elapsed value of the transmitted light amount into three levels, that is, the normal amount and the small amount, and the skin moisture amount is increased based on the elapsed value and the change amount of the transmitted light amount. It is classified into three levels, standard, and low.

When sebum was collected from the cheeks of the face for B, C, and D, and sebum / water content was determined by the determination unit 26, the determination results shown in FIG. 3 were obtained. The determination result of the skin moisture content is almost the same as the measurement result of the skin moisture content by the conventional measuring device which measures the skin impedance (capacitance) by pressing the cheek electrode of the subjects A, B, C and D. I was doing it. Figure 4
As shown in, the elapsed value of the amount of transmitted light rapidly decreases to about 30 seconds after the operation of the exhaust fan 18 starts, and thereafter gradually decreases. When the number of revolutions of the exhaust fan 18 is lowered to perform gentle ventilation, the change in the elapsed value for the first 30 seconds becomes gentle. Then, as shown in FIG. 5, when the elapsed value is measured with the exhaust fan 18 completely stopped, the decrease in the elapsed value for the first 30 seconds cannot be detected. In other words, subject C with a standard amount of sebum secretion
However, the change in the elapsed value becomes closer to that of the subject D who has a large amount of sebum secretion.

打ち込める。According to the sebum / water content measuring apparatus of the first embodiment, the skin oil content can be determined by using the sebum measurement mechanism, the sensor and the determination circuit almost as they are. No mechanism, sensor or judgment circuit is required. Therefore, it is possible to provide a device that is inexpensive, small and lightweight, has a simple operation, and has sufficient and sufficient determination accuracy. For example, by pressing a comb-shaped electrode against the subject's cheek, skin impedance (capacitance,
It is not necessary to measure the resonance frequency), and the operator is freed from cleaning and disinfecting the comb-shaped electrode surface for each subject.
Further, the amount of water can be measured only by collecting painless sebum in a short time when the tape 12 is pressed against the skin surface, and the tape 12 is disposable, so that the subject is relieved of physical pain and uncleanness. There is no resistance to sharing one measuring machine with a large number of unspecified subjects. For the operator, the operation of the measuring machine is simplified, there is no room for making an operation error, and the reliability of the measurement result is increased. You can devote your concentration power to the observation and dialogue of customers, and devote yourself to sales such as cosmetics sales.

Even in a short time of about 30 seconds, the amount of water can be measured by efficiently evaporating the water from the sebum adhesion area. During forced drying, the exhaust fan 18 blows air at room temperature onto the sebum-attached surface, so that the light source element 15 and the light receiving element 17 are not thermally affected by the surroundings such as heating with a heater or blowing hot air. It does not affect the accuracy of the measurement due to the influence. As a method for forcibly drying the sebum adhesion area, other forced drying means, for example, normal temperature decompression, dry air spraying, ultrasonic vibration, etc. may be performed. When the thermal influence on the light source element 15 and the light receiving element 17 does not pose a problem, a lamp, resistance heating, ceramic heater, electromagnetic wave heating, hot air blowing or the like may be used. Further, a material other than the tape 12 can be used as the measurement medium. For example, a transparent resin or transparent glass having frosted glass-like fine irregularities formed on its surface may be used. Ordinary paper tape or non-woven or woven fabric may be used. Instead of the tape-like continuous appearance, pellets for collecting sebum that are cut into a circular or square appearance may be used.

ｍＶレベルの変化量を正確に測定できる。Further, since the tape 12 is stopped at the position where the light source element 15 and the light receiving element 17 are opposed to each other, the received light amount measurement is performed twice and the forced drying is performed between them, so that the difference in the transmitted light amount depending on the location of the material of the greasing paper or There is no concern that the difference in the amount of sebum deposited depending on the location will be erroneously measured as the amount of change. In addition, compared to the difference in transmitted light amount due to the difference in the amount of sebum adhered, the difference in the transmitted light amount due to the difference in skin moisture amount is only a few percent, which is a very small difference. Therefore, it is essential to have a mechanism for stably reading minute changes. .
In that respect, the output of the variable light-receiving element 17 is fed back to maintain the light-emission output of the light-source element 15 constant, so that the thermal disturbance due to the tape 12 coming in and out is eliminated, and the change amount of the transmitted light amount of several mV level can be reduced. Can measure accurately.

As shown in FIGS. 5 and 6, in the sebum / moisture measuring apparatus of the second embodiment, the tape 41 of the degreasing paper is pulled out from the supply reel 42 and used for the sebum / moisture measurement. Supply reel 4
The tape 41 extending from the case 2 to the outside of the case 13 goes around the outer circumference of the sebum collecting portion 35, returns to the inside of the case 13 again, passes through the gap between the light source portion 47 and the detecting portion 46, and is wound around the discharge reel 43. The handle plate 32 provided on one surface of the case 13 is interlocked with the discharge reel 43, and the tape 41 can be wound around the discharge reel 43 by inserting a fingertip into the hole 33 and rotating in the arrow direction. A handle plate (not shown) interlocking with the supply reel 42 is arranged on the surface opposite to the case 31, and is rotated to rotate the supply reel 42.
The tape 41 can be rewound on the tape. And tape 4
A mark is printed on the edge of 1 in units of length of the tape 41 from the center of the sampling unit 35 to the center of the light receiving element 48.
Therefore, the operator collects the sebum while rotating the handle plate 32 and positioning the mark of the tape 41 at the center of the sampling portion 35. After that, the handle plate 32 is rotated until the next mark, and the sebum adhesion area of the tape 41 is sent to the position where the light source element 49 and the light receiving element 48 face each other.
