[Detailed description of the invention]

The present invention relates to a hair diagnostic device, and more particularly to a hair diagnostic device that can reliably diagnose hair quality with a simple configuration. First, before explaining one embodiment of the hair diagnosis device of the present invention, an outline of the hair diagnosis device of the present invention will be explained. In order to keep hair beautiful, various treatments such as treatments and perms are performed, but since hair differs from person to person, it is necessary to perform treatments according to the characteristics of each individual hair. To do this, it is first necessary to understand the characteristics of individual hair. Therefore, the hair diagnostic device of the present invention is designed to measure the characteristics of hair and use it as data for determining what treatment should be performed on each hair. A method has already been proposed for diagnosing hair by measuring hair diameter, tensile strength, and tensile elongation.
As shown in the average value of the measured strength of hair A, B, C, and D in Figure 1 and the average value of the measured value of elongation of hair A, B, C, and D in Figure 2. Since the strength and elongation of the hair change depending on the moisture absorption state of the hair, if the moisture absorption state of the hair is ignored, there is a risk of misdiagnosis. In FIGS. 1 and 2, the ● mark indicates hair left indoors (approximately 60% RH), and the X mark indicates hair that has been water-absorbed. Therefore, in addition to the above-mentioned measurement items, the hair diagnostic device of the present invention measures the moisture content of the hair, taking into account the moisture absorption state of the hair at that time.
This makes it possible to make even more accurate diagnoses. Next, an embodiment of the hair diagnosis device of the present invention will be described. FIG. 3 is a block diagram showing an embodiment of an electronic control device using a microcomputer (microcomputer) of the hair diagnosis device according to the present invention, in which 1 is a microcomputer, 2 is an AC power supply, 3 is a DC power supply circuit, 4 is an oscillation circuit, 5 is a moisture content measuring electrode, 6 is a CR oscillation circuit,
7 is a reference pulse generator, 8 is a frequency counter, 9
(or 31) is the keyboard, 10 is the load cell,
11 and 27 are amplifiers, 12 and 15 are A/D converters, 26 is an elongation measuring device, 16 is a driver circuit, and 17 is a display device. FIG. 4 is a schematic configuration diagram of a tensile tester, and the tensile tester includes a load cell 1 having a hook 18 above the machine frame 25 that grips one end of the test hair 28.
The crosshead 20 is provided with a clamp 19 for grasping the other end of the hair 28, and both ends of the crosshead 20 are screwed into screws 21 so that the screws 21 are positioned on both sides of the hair 28. It is arranged in the machine frame 25, and the gear 2 is attached to one end of the screw thread 21.
A gear box 23 having a gear that meshes with the gear 22 is installed, and the gear of the gear box 23 is driven by a drive motor 24.
The crosshead 20 is moved downward (in the direction of arrow A) at a constant speed by rotating the
Apply a load through the The load cell 10 is an application of a strain gauge, and the load applied to the strain gauge causes strain in the strain gauge, and the resistance value changes in accordance with this strain. It is assembled into a bridge circuit and converted into a voltage signal. Therefore, the load cell 10 is configured to convert the above-mentioned load into a voltage and apply it to the A/D converter 12 via the amplifier 11. In addition, in FIG. 4, reference numeral 26 is an elongation measuring device, which will be explained in conjunction with FIG.
The slide knob 29 of the slide volume 13 is moved downward or upward according to the movement of the crosshead 20. When the slide knob 29 of the slide volume 13 is pushed upward, the resistance value becomes "0", and as it is pushed downward, the resistance value becomes "0". , the resistance value increases. Therefore, the hair 28 is set in the above-mentioned tensile tester as described above. At this time, make sure that the hair is not slack or stretched, and also make sure that the slide knob 29 of the slide volume 13 is at the position where the resistance value is "0". In this way, when the crosshead 20 is moved downward (in the direction of arrow A) at a constant speed as described above, the hair 28 is pulled, and the slide knob 29 of the slide volume 13 moves downward accordingly. The resistance value gradually increases. This change in resistance value is converted into a voltage signal by the voltage conversion circuit 14, amplified by the amplifier 27, and applied to the A/D converter 15. 6 and 7 are explanatory diagrams showing embodiments of the keyboard 9 (or 31).

【table】

[Table] FIGS. 11 and 12 are flowcharts showing the operation of the embodiment of the hair diagnosis device of the present invention, respectively. FIG. 11 shows a flowchart when the keyboard 9 and display device 17 are used, and the operation of the hair diagnosis device will be explained according to this flowchart. First, the power switch (not shown) of the hair diagnosis device is turned on, and the moisture content of the hair to be diagnosed is then measured. That is, the capacitance of the hair is detected by the moisture content measuring electrode 5, converted into a frequency corresponding to the capacitance by the CR oscillation circuit 6, and counted by the frequency counter 8, and the microcomputer Enter 1. The frequency at this time is
Memory as M10. Convert M10 to moisture content M11. M11 is stored in memory and M11 is displayed on the display device 17. Next, the diameter of the hair 28 to be diagnosed is measured using a micrometer (not shown). Input the measured hair diameter (measurement result) using the keyboard 9,
Memory as M1. In this case, for example, if the hair diameter is 80 μm, the "8" key on the keyboard 9,
Press the "0" key and the "μm" key in this order to input. Then, the memorized M1 is displayed on the thickness display section of the display device 17. Next, as shown in FIG. 4, both ends of the hair 28 are gripped and fixed with the clamps 18 and 19 of the tensile tester, and the load cell 10, amplifier 11, elongation measuring device 26, amplifier 27 The measurement is started by setting the output signals from each to "0". The drive electric motor 24 is driven to drive the two screws 2 at a constant speed through the gears in the gear box 23 and the gear 22.
Drive 1. Then, the crosshead 20 moves downward (in the direction of arrow A) at a constant speed, the hair 28 is pulled and a load is applied to the load cell 10, and the voltage signals from the load cell 10 and the amplifier 11 gradually increase. Therefore, at regular intervals, the A/D converter 12
The magnitudes of the voltage signals that are A/D converted and input to the microcomputer 1 are compared, and the maximum voltage signal M2 is determined and stored in memory. This operation continues until the hair 28 is cut. (When hair 28 is cut, M3=
Although it becomes 0, it may not be exactly right, so
If the value is less than a predetermined constant K, which is a number close to 0, it is considered that the hair 28 has been cut. However, the above M3 is a comparison voltage signal when determining the maximum voltage signal M2. ) At the same time that it is detected that the hair 28 has been cut, the voltage signals from the elongation measuring device 26 and the amplifier 27 at this time are A/D converted by the A/D converter 15.
It is converted into D, inputted to microcomputer 1, and stored in memory as M7. The maximum voltage signal M2 obtained in this way
Multiply by a certain value to convert to tensile strength M4.
Next, hair strength M5 is calculated from M5=M4/M1. On the other hand, M7 is converted to elongation M8 from a predetermined relationship between the elongation and the voltage signal. M4, M5, and M8 determined in this manner are respectively stored in memory, and M4 is displayed on the tensile strength display section of the display device 17, and M8 is displayed on the elongation display section of the display device 17. Next, using the relationship between hair strength and hair growth, for example, as in the hair quality rank shown in Figure 10,
Rank M12 is determined from M5 and M8 and stored in memory, and M12 is displayed on the rank display section of the display device 17. Next, when diagnosing another hair, if the moisture content of the hair is measured as described above, the memory contents for the previous hair (M10, M11, M1, M2, M3,
M4, M5, M6, M7, M8, M12) are all cleared, so you can perform the current hair diagnosis by performing the same operations as the previous hair diagnosis. In this way, each hair is sequentially diagnosed. The hair quality is diagnosed based on the hair quality rank determined in this way, for example, as shown in Table 1. However, as shown in Figures 1 and 2, depending on the water absorption state of the hair, Since the strength and elongation of hair change, the results of the hair moisture content determined here should also be taken into consideration when making a diagnosis. In other words, if the hair has a high moisture content, it is diagnosed by taking into account that the strength of the hair is low and the hair is elongated to a large extent. on the other hand,
Hair with a low moisture content has greater strength;
Diagnose by taking into account the small growth. Next time, if you want to perform a diagnosis by calculating the average of multiple hairs of the same type, perform the diagnosis for each hair as described above, and after the first hair diagnosis is completed, press the "M" key on the keyboard 9 and set M5 to a1. Rememory M4 as b1, M8 as c1, and M1 as d1. Then, when the second hair diameter is measured and the hair diameter is input as described above, M11,
Memories other than a1, b1, c1, and d1 disappear. After the second hair measurement, M1, M4, M5,
When M8 and M12 are obtained, press the "M" key,
Rememory M5 as a2, M4 as b2, M8 as c2, and M1 as d2. In this way, multiple (for example, n) hairs are sequentially
a1, a2, ...an, b1, b2, ...bn, c1, c2, ...,
Get cn, d1, d2,...dn. So keyboard 9
When you press the "T" key, the average value of each of the n hairs is calculated, and the average value of the thickness is displayed on the display device 1.
7, the average value of the tensile strength is shown in the tensile strength display part of the display device 17, and the average value of the elongation is shown in the elongation display part of the display device 17, according to the average data at this time. Hair quality rank M13 is displayed on the rank display section of the display device 17. Of course, regarding the moisture content, the content of M11 is displayed on the moisture content display section of the display device 17. Next, even if you want average data for multiple hairs of the same type, not all hairs will be measured correctly, so if unnecessary data appears along the way, press the "M" key on the keyboard 9. If you don't press it, it won't be memorized again, so the data for that hair will disappear the next time you measure it. As a result, average data can be obtained in the same manner as above for effective hair excluding this unnecessary data. Similarly to the above, if you want the average data of multiple hairs of the same type and unnecessary data appears in the final episode, of course you can press "M" on the keyboard 9.
If you press the "T" key on the keyboard 9 without pressing any key, this unnecessary data will be displayed on the display device 17.
The data disappears from the display section, and the average data for all the hairs stored so far is obtained, excluding this unnecessary data.
