DETAILED DESCRIPTION OF THE INVENTION The present invention applies tension to the test hair, drops a predetermined reagent, and measures the length of the test hair or the time it takes for the test hair to break. In a hair quality diagnostic device that measures the degree of hair damage and diagnoses the quality of healthy, normal, and damaged hair, the structure of a fixture that inserts and attaches the hair to be tested and a weight that serves as a means for applying tension. It is related to.

Conventionally, a predetermined weight was attached to the hair to be examined,
A cylindrical fixture has been proposed in order to receive the reagent being dropped and make sufficient contact with the test hair; A small-diameter through hole was provided, and about five hairs to be tested were inserted into the through hole in a bundle, and the remaining hairs to be tested at both ends were fixed using an appropriate method.

However, with this method, the hair to be tested must be inserted into a narrow through hole, and cleaning the fixture after measurement is quite troublesome. It had no effect on the problem, and it was desired to speed up and simplify the installation time of the hair to be tested.

The present invention has been made in view of the above-mentioned points, and relates to a test hair mounting structure consisting of a test hair fixture and a weight, which is directed from the center of the test hair fixture and the weight toward the outer periphery. A cross-section or a shape that opens with a

Next, an overview of the operation of the hair diagnostic apparatus according to the embodiment of the present invention having the above-described configuration will be explained.

First, as shown in FIG.
The weight part 3 is attached with a male screw 4 and a female screw 6 at the lower end of the
In the combined state, the test hair (a bundle of about 5 hairs) is inserted into the concave narrow grooves 5 and 12, and then the upper and lower ends are inserted into the soft gaps 13, 14. are fixed to the upper end of the test hair fixture 1 and the lower end of the weight part 8. At this time, the loose portion of the hair to be tested is taken out through the front openings of the concave narrow grooves 5 and 12. After fixing the test hair, the weight part 3 is rotated in the opposite direction to the screw part to separate from the test hair fixture 1, and the weight part 3 is suspended through the test hair. In the lowered state, the upper end of the test hair fixture 1 is attached to the substrate 16.
(as shown in the fifth figure).

Next, the cylindrical member 31 is moved so that a position detection tool (not shown) attached to one end of the weight part 3 is located 2 mm above the first photosensor 29. Adjust by moving up or down. Further, power is started to be applied to the hair quality diagnostic apparatus having the configuration shown in the block diagram of FIG. 6 above. Then, power is started to be applied to the heater 26 and the blower fan 25 to operate the heating device 24, and the temperature of the hair attachment device 1 is set to a predetermined temperature (40 to 60°C).
The temperature is adjusted by well-known temperature control means so that

Next, when the reagent dropping device 38 is activated, 0.01
A predetermined amount of ~0.03cc of reagent is added to the test hair fixture 1 above.
It is dropped into the narrow groove 5 of. When this reagent is dropped, a signal is sent to the measurement start detection circuit 40 by a detection means (not shown) that automatically detects that the reagent has been dropped, and a signal is sent to the timer circuit 4 via the control circuit 44.
5 to start time measurement. Since the hair to be tested is inserted into the narrow groove 5, the reagent uniformly contacts the hair to be tested, causing it to swell and soften, and then begins to stretch under tension from the weight 3. Then, when this weight 3 gradually moves downward and blocks the light from the first photosensor 29 by the detection tool for position detection, the initial predetermined interval elongation time detection circuit 41 detects that the reagent will elongate by 2 mm after dropping. time
T ₁ is displayed on the display section 48, and the time is measured again. Then, when the test hair grows further and the light from the second photosensor 30 is blocked by the position detecting device, the time T ₂ required for the hair to grow by 10 mm is calculated by the predetermined interval growth time detection circuit 42. It is displayed on the display unit 48 and the time measurement is continued.

Now, when the test hair cannot withstand the tension of the weight 3 and is cut, the weight 3 falls and the contact plate 35 is displaced, which closes the switch 37 and stops the time measurement by the fall detection circuit 43. At the same time, the time at which it stopped is set as the cutting time _T3 on the display section 4.
Display on 8. By comparing and determining the above-mentioned measured data with the data of T ₁ , T ₂ and T ₃ for healthy hair, normal hair and damaged hair, the quality of the hair to be tested is determined and displayed on the display section 48 to display the hair quality. Finish the quality diagnosis.

As explained above, according to the present invention, there is provided a weight that applies tension to the test hair, a reagent dropping device that drops a predetermined reagent onto the test hair, and the test hair starts to grow when the reagent is dropped. A hair quality diagnostic device that diagnoses the quality of healthy hair, normal hair, and damaged hair by measuring the time it takes for the hair to grow, the time it takes to grow to a specified length, or the time it takes to cut the hair to determine the degree of damage to the hair. In order to insert the test hair into the test hair fixture, the test hair fixture and the weight have a concave narrow groove opening from the center toward the outer periphery and having a square or square cross section. Since it is installed in the axial direction of the weight, it can be installed very easily by simply inserting the hair to be tested, and since it makes sufficient contact with the reagent, it can be used to measure hair growth time in a short time and with little variation in data. and the test hair fixture and the weight part are configured to be able to be combined,
In this combined state, both ends of the test hair are fixed to the test hair fixture and the ends of the weight part by appropriate fixing means, so that the weight part oscillates when the test hair is fixed. Not only does it not move, making the fixing work much easier, but it also eliminates the inconvenience of cutting the hair to be tested because no unreasonable force is applied to the hair to be tested during fixation. It can be effective.
