DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Use] The present invention relates to a skin characteristic checking device used to obtain data necessary for skin care.

[Conventional technology] There are individual differences in the amount of sebum and moisture secreted on the surface of human skin.For example, people with a high amount of sebum tend to have oily skin, and people with a low amount of moisture tend to have dry skin. easy to become.

In order to keep your skin supple and supple, it is best to know your skin's characteristics well and use cosmetics that are suitable for you, so it has been a tradition to scientifically evaluate an individual's sebum content and skin moisture content. things are being done. For example, in the case of sebum content, the method used for a long time was to collect sebum from the skin surface and quantify it using chemical methods such as solvent extraction, but recently, instead of methods that require such complicated analysis operations, For example, a sebum amount measuring device has been developed that uses a CdS cell or the like as a sensor and allows an employee to easily measure the amount of sebum at a store such as a cosmetics store.

In addition, in the case of skin moisture content, a measuring device is used that has a positive electrode and a negative electrode on the contact surface that comes into contact with the skin, so that when it comes into contact with the skin, a DC circuit is formed by the moisture on the skin surface. A measuring device has been developed that determines the moisture content from the electrical resistance during contact.

[Problems to be Solved by the Invention] By the way, in order to select the most suitable cosmetic for each person's skin, it is better to comprehensively evaluate both of the moisture content or sebum content, rather than making a judgment based on either one of them. It is much preferable to select For this purpose, a simple checking device suitable for comprehensively evaluating skin moisture content and sebum content is required, but such a device has not been available to date.

In view of the above circumstances, an object of the present invention is to provide a check device that can easily measure both skin moisture content and sebum content and display the results simultaneously to comprehensively judge skin characteristics. The topic is

The display board 22 can be removed by hooking a nail into a recess 27 provided at the peripheral edge of the recess 21 and lifting it up.

In this way, since the display board 22 is removable, it can be replaced with one with a different sebum amount or water loss range, or with a different message.

As shown in FIG. 2, the peripheral wall of the main body 2 includes a changeover switch 30, a zero level adjustment dial 31, and a power adapter 3.
A connector 35 for connecting the three jacks 34 is provided. The changeover switch 30 has two positions, ■ and ■, and is designed to be switched depending on the season and the age of the subject.

As shown in FIG. 3, the sebum amount detecting tool 3 includes a casing 40 in the form of a cylinder with a ceiling, a central shaft 41 extending downward from the ceiling inside the casing 40, and vertically extending along the central shaft 41. It is composed of a bottomed sleeve 42 that slides and a compression spring 43 that presses and biases the bottomed sleeve 42 downward. As shown by the button line, a sebum collection tip 4 (to be described later) is provided on the bottom side of the bottomed sleeve 42.
A fitting recess 44 is formed so that the device 5 can be installed with its sebum collecting surface facing downward.

As shown in FIG. 4, the sebum collection chip 45 has a two-layer structure including a support layer 47 and a test layer 48, and the surface of the test layer 48 is pressed against the skin surface as a sebum collection surface 48a. It looks like this. The support layer 47 is
Since it is made of an elastic material such as urethane foam and elastically supports the test layer 48, the test layer 48 easily follows the uneven surface. The inspection layer 48 is formed of a paper material containing iodine and a silver compound, and when oil permeates into the paper material, an amount of iodine corresponding to the oil content is liberated, and the silver compound is released. It is colored black.

The degree of black color development can be measured by the amount of infrared absorption, and it is known that the relationship between the two appears as a clear straight line, as shown in FIG.

On the other hand, as described above, the main body 2 includes the lower end portion of the sebum amount detecting device 3, that is, the detecting section 3 to which the sebum sampling chip 45 is attached.
A measurement hole 7 into which a sensor is inserted and held is provided, and as shown in FIG. An infrared lamp 50 and a light receiving element 51 such as a photodiode are provided for measuring the amount of sebum. The infrared lamp 50 is connected to the sebum collection surface 48a of the sebum collection chip 45.
The light receiving element 51 detects the sebum collecting surface 48 of the irradiated light.
It is designed to receive the light reflected by a. Therefore, the darker the sebum collecting surface 48a is, the greater the amount of infrared rays absorbed by the sebum collecting surface and the smaller the amount of light received by the light receiving element 5l. The output signal of the light receiving element 51 is amplified by an amplifier as described later, converted from an analog output to a digital output by an A/D converter, and then sent to a data processing section.

As shown in FIG. 1, the moisture detector 4 includes a cylindrical casing 60, a sleeve 62 attached to the tip of the casing 60, and a sensing disk 63 fitted to the tip of the sleeve 62. have. The sensing disk 63 is
As shown in FIG. 7 when viewed from below, it is divided into three regions, and the center region and the outermost region are the conductor portions 65.
．． 66, and a region sandwiched between these two conductor parts 65 and 66 is formed as an insulator part 67. On the inner surface of this disc 63, two conductive wires are connected to the center conductor part 65 and the outer conductor part 66, respectively.
The other end of the wire is mounted on a substrate within the casing 60. When the sensing disc 63 is pressed against the skin, a direct current circuit is formed in this area through the moisture on the skin surface, with the central conductor portion 65 serving as an anode and the outer conductor portion 66 serving as a cathode. It has become. Note that 69 is a hand switch for causing current to flow through the DC circuit. Also,
Changes in the electrical resistance value of the DC circuit are transmitted as electrical signals into the main body 2 via a cord 70 connected to the upper end of the substrate. Therefore, when the hand switch 69 of the moisture detector 4 is turned ON and the tip of the sleeve 62 is pressed against the skin, a current corresponding to the amount of moisture present on the skin surface flows between the two conductive parts 65 and 66 (this As shown in FIG. 8, the electrical resistance value in the DC circuit decreases as the amount of water increases. However, in order to accurately measure the electrical resistance value, it is necessary to press the sensing surface (surface) of the sensing disk 63 against the skin surface for a sufficient period of time to establish the DC circuit. The holding hole 8 of the wooden body 2 is formed in a two-stage shape with a small diameter hole in the center of the bottom into which the sleeve 62 fits, so that the moisture detection device 4 can be held stably. It has become.

FIG. 9 is a block diagram showing a data processing section provided in the main body 2, and the output signal of the light receiving element 51 that receives the light irradiated via the sebum sampling chip 45 of the sebum amount detection device 3 is as follows. The data is input to an arithmetic processing circuit 83 via an amplifier 81 and an A/D converter 82, and the amount of sebum is determined. Further, the output signal of the moisture detector 4 is read by the reading means 85 as a change in electrical resistance value,
It is input to the arithmetic processing circuit 83 via the D converter 87, and the water content is determined.

The sebum amount and moisture amount determined in this way are displayed on the display section 20.
displayed at the same time. This display is lamp 24,...
The amount of moisture is measured by lighting up the lamps in the row of lamps along the X-axis (indicated by H), and the amount of sebum is determined by lighting up the lamps in the row of lamps along the Y-axis (indicated by F). This is done respectively. The moisture content is higher on the right side of the lamp row H and lower on the left side. Further, the amount of sebum is higher in the upper part of the lamp row F and less in the lower part. In addition to the lamps of these lamp rows H and F, the lamp 24 of one display window 25 specified by the moisture content and sebum content is also lit. This illuminated display window has an X-axis coordinate determined by the position of the rightmost lit lamp in the lamp row H, and a Y-axis coordinate determined by the position of the uppermost lit lamp in the lamp row F. For example, when both the amount of moisture and the amount of sebum are normal, the lamp in the display window E lights up.

Next, to explain how to use this device, first connect the power source and press the clear button 13. A tip 45 for sebum amount detection is set in the sebum amount detection tool 3. At this time, be careful not to get oil from your hands on the tip. Thereafter, the cover 10 is opened, the detection tool 3 is inserted into the measurement hole 7, and the changeover switch 30 is set to the ■ side. In this state, press the sebum amount detection button 14 to adjust the level.

That is, the zero level adjustment dial 31 is turned to adjust so that only the zero level display lamp 24a among the lamps in the lamp row F indicating the amount of sebum is lit. When this adjustment is completed, press the clear button l3.

When actually measuring the amount of sebum, place the tip of the detector 3 on the subject's skin (for example, the forehead) to adsorb sebum, then insert it into the measurement hole 7 again and press the sebum amount detection button 14. push. Then, the lamps in the lower part A17 of the lamp row F are lit on the ship without revealing the sebum II;. Of these lit lamps, the lamp on the -1] side (l {1'/.) is sebum! Shows 11 levels.

The selector switch 30 is set to the ■ side in spring and summer, which applies to all ages, and in autumn and winter, it is set to the ■ side for young people (18 to 24 years old), and to the ■ side for older people (25 years and older). > is set to the ■ side.

After the measurement of sebum content is completed, the moisture content is next measured. First, the detection surface of the sensing disk 53 of the moisture detection device 4 is wiped with a dry cloth and brought into close contact with the subject's skin (for example, the cheekbone area).

If the hand switch 69 of the detection tool 4 is pressed in this state, the lamps in the lamp row H representing the moisture content will light up in order from the lowest one. Among these lit lamps, the rightmost (upper) lamp indicates the moisture content at that time. At the same time, one lamp in the display window 25 that is determined by the amount of sebum and moisture is lit, so the most suitable cosmetic can be selected based on this.

Note that either the measurement of the amount of sebum or the measurement of the amount of water may be performed first.

Regarding the arrows X, Y and message portions of the display section 2o of this skin characteristic checking device, the portions representing sebum amount and the portions representing moisture content are color-coded (for example, sebum amount is brown, moisture amount is blue). It is more preferable to do so because it makes it easier to distinguish between the two.

[Effects of the Invention] As is clear from the above description, the skin characteristic checking device according to the present invention measures the sebum amount and moisture amount using rIR. Since it is possible to measure Ql and display both measurement results at the same time, it is now possible to comprehensively judge sebum content and moisture content and select the most suitable cosmetic.
