Description

Hair sample jig

The present disclosure relates to a hair sample jig for fixing a plurality of collected hair samples to a sheet.
This application claims the benefit of priority over Japanese Patent Application No. 2018-091648, filed on May 10, 2018, which is incorporated herein by reference. All are included in this application.

Conventionally, a jig for fixing a plurality of collected hair samples to a flat sheet and cutting them to a desired length is known. In this type of conventional jig, a hair sample is attached to a sheet coated with an adhesive.

For example, in the unit sheet for fixing eyelash extensions disclosed in Patent Document 1, a release paper adhered to a rectangular base paper, a set paper adhered to the release paper so as to be separable, and the set paper The eyelash extension hairs are arranged in a limited number and bonded in a separable manner.

Japanese Patent Publication “JP 2010-209503 A (published September 24, 2010)”

However, the conventional hair sample jig has a problem in that the hair sample is hindered because an adhesive is used to fix the hair sample to the set paper.

For example, when fixing a hair sample to a sheet coated with an adhesive or a pressure sensitive adhesive or adjusting the position on the sheet, the fingertips reach the sheet coated with the adhesive or the pressure sensitive adhesive. The work of attaching the sample to the sheet is not easy. Further, when it becomes necessary to adjust the position where the hair sample is attached, it is necessary to remove the hair sample from the sheet and then attach it again to the sheet, which is troublesome.

Furthermore, when collecting a hair sample fragment cut to a desired length, it is not easy to remove the hair sample fragment from the adhesive sheet.

In addition, when correcting the hair sample attachment position or peeling the cut hair sample from the sheet, the adhesive adheres to the hair sample, and the adhesive is washed when handling the hair sample in the subsequent process. It becomes necessary to do.

The reason for using the adhesive to fix the hair sample to the set paper is that the hair has some wrinkles and is not straight, so align the direction on the sheet and fix the hair sample straight to the desired length. This is because, in order to cut the hair sample, it is considered that the hair sample is temporarily fixed to an adhesive or sticky sheet.

One aspect of the present disclosure has been made in view of the above-described conventional problems, and an object thereof is to fix a hair sample to a sheet without using an adhesive, and to attach a plurality of hair samples to a predetermined shape. An object of the present invention is to provide a hair sample jig that can be easily cut to a length.

In order to solve the above-described problem, the hair sample jig according to one aspect of the present disclosure is a hair sample jig that fixes a plurality of collected hair samples to a first sheet and cuts the hair sample to a desired length. In the first sheet, a plurality of protrusions are erected in an array of first and second directions, and the hair sample is formed of a plurality of protrusions erected in the array. The movement is suppressed except for the movement along the first direction by the protrusions facing each side by being placed on the first sheet in a state of extending linearly in a plurality of first directions in between, The mark which shows the cutting position of the hair sample in the said 1st direction is displayed on the at least edge part of the said 1st sheet | seat.

According to one aspect of the present disclosure, there is an effect of providing a hair sample jig that can fix a hair sample to a sheet without using an adhesive.

[Embodiment 1]
An embodiment of the present disclosure will be described below with reference to FIGS. 1 to 5.

The hair sample jig according to an embodiment of the present disclosure fixes a plurality of collected hair samples to a flat sheet and cuts them to a desired length.

The configuration of the hair sample jig 1A of the present embodiment will be described based on FIGS. 1 to 3 (a) and (b). FIG. 1 is a perspective view showing a configuration of a hair sample jig 1A in the present embodiment. FIG. 2 is a plan view showing the configuration of the hair sample jig 1A. (A) of FIG. 3 is a top view which shows the mark 21 which is an example of the mark in the hair sample jig | tool 1A. FIG. 3B is a cross-sectional view showing a mark 22 which is another example of the mark on the hair sample jig 1A.
As shown in FIGS. 1 and 2, the hair sample jig 1 </ b> A of the present embodiment includes a base sheet 2 as a second sheet, and a flat sheet 3 as a first sheet laminated on the upper surface of the base sheet 2. And a plurality of protrusions 10 erected on the flat sheet 3. Further, a mark 20 indicating the cutting position of the hair sample M is displayed at least at the end of the flat sheet 3.

The hair sample M of the present embodiment is intended to be “hair growing on the subject”. When the subject is a human, examples of hair include head hair, eyelashes, eyebrows, eyelashes, nasal hair, ear hair, eyelashes, pubic hair, and body hair. In the present embodiment, the hair sample M is a hair sample jig 1A assuming human hair, for example.

Here, the use of hair as the biological sample has the following advantages over the use of blood, saliva, or the like as the biological sample.
(1) Hair collection is non-invasive and easy. For this reason, even a person who is not a doctor or a medical staff can collect a sample.
(2) Low risk of contamination by other types of samples. For example, since the level of the physiologically active substance is usually different between saliva and blood, the level of the physiologically active substance cannot be accurately measured if blood is mixed when collecting saliva. However, the collected hair can easily remove contamination of other types of samples (blood, saliva, etc.) by washing.
(3) Suitable for measuring the “accumulated amount” of a physiologically active substance. That is, the level of the physiologically active substance measured from blood, saliva, etc. tends to be influenced by biological conditions and environmental conditions at the time of sample collection due to circadian rhythm, acute biological reaction, and the like. On the other hand, the elongation speed of hair is about 1 cm / month for scalp hair. Therefore, by using hair as a sample, it is possible to obtain a measurement value reflecting the “accumulated amount of physiologically active substance secreted during a specific period”. The “physiologically active substance” is intended to be a substance related to the maintenance and regulation of life activity and physiological function. Specific examples of the physiologically active substance include hormones, neurotransmitters, cytokines, vitamins, enzymes, proteins, peptides and the like.

The hair sample M of the present disclosure is used, for example, as a hair sample for measuring a change with time of the accumulation amount of a physiologically active substance in hair collected from a subject. For this reason, in order to measure the time-dependent change of the hair sample M, it is necessary to measure the property of each part in one hair.

For this reason, the hair sample jig 1A of the present embodiment is capable of accommodating a plurality of hair samples M such as head hairs so that they can be divided and adopted at the same time of hair growth. .

Note that the hair sample M of the present embodiment includes not only human hair but also mammalian hair other than human hair. Examples of mammals other than humans include primates (monkeys, apes, etc.), cloven-hoofs (cattle, wild boar, pigs, sheep, goats, etc.), odd hoofs (horses, etc.), rodents (mouse, rats, hamsters). , Squirrel, etc.), rabbit eyes (rabbit, etc.), meat (dogs, cats, ferrets, etc.) and the like. The above-described mammals other than humans may be domestic animals, pet animals, or wild animals.

Next, the base sheet 2 is a fixed-shaped sheet for stacking and supporting the flat sheet 3 on the upper side. The fixed shape may be any of a parallelogram, a rhombus, a polygon, a circle, an ellipse, and an indeterminate shape other than a rectangle such as a rectangle or a square. In the present embodiment, the base sheet 2 is, for example, rectangular. In addition, it is preferable that the base sheet 2 has a length that is equal to or longer than a length at which a desired length portion of the hair sample M to be fixed can be fixed.

The flat sheet 3 is a sheet for fixing a plurality of hair samples M between the plurality of protrusions 10 while a plurality of protrusions 10 protrude upward on the upper surface thereof.

In the present embodiment, the flat sheet 3 is laminated so as to be separable from the base sheet 2. However, it is not necessarily limited to this, and may be integrated. That is, the flat sheet 3 and the base sheet 2 may be integrated so as not to be separated.

In the case of being integrated, when cutting the hair sample M, the base sheet 2 is also cut together with the flat sheet 3. In the case of cutting up to the base sheet 2, the base sheet 2 is preferably made of a material that can be easily cut with a blade such as a scissors, a knife, or a cutter, as with the flat sheet 3. Specifically, the material of the base sheet 2 and the flat sheet 3 can be, for example, cloth, wood board, paper, plastic, resin, rubber, metal foil, carbon fiber board, or the like. In the case where the base sheet 2 is not cut, the base sheet 2 is simply used as a support for the flat sheet 3, so that a material other than a material that can be easily cut can be used.

In the present embodiment, the planar sheet 3 and the base sheet 2 have the same size, for example. When the flat sheet 3 and the base sheet 2 have the same size, when cutting the hair sample M, at least the flat sheet 3 is also cut and divided according to the cutting length of the hair sample M.

However, the present invention is not necessarily limited to this. For example, as shown in FIG. 8 to be described later, the divided sheets 3a, 3b, 3c divided on the base sheet 2 may be fixed in accordance with the cutting position of the hair sample M. Good.

The divided flat sheet 3 is laminated so as to be separable from the base sheet 2. Specifically, the flat sheet 3 and the base sheet 2 are fixed to each other by, for example, an adhesive such as an adhesive so as to be easily separated. As a result, in the hair sample jig 1A of the present embodiment, after the hair sample M is cut, the divided flat sheet is held in a state where the fragment of the hair sample M is held on the divided flat sheet 3. 3 can be removed from the base sheet 2.

Next, in the present embodiment, the plurality of protrusions 10 on the flat sheet 3 are erected in an array of first and second directions on the upper surface of the rectangular flat sheet 3. That is, in the present embodiment, since the flat sheet 3 is, for example, rectangular, the plurality of protrusions 10 are along the vertical direction parallel to the long side of the rectangular flat sheet 3 and the horizontal direction parallel to the short side. It is erected in an array like a grid. Thereby, in this Embodiment, while a 1st direction is the vertical direction of the plane sheet 3, a 2nd direction is a horizontal direction of the plane sheet 3, and a 1st direction and a 2nd direction are orthogonally crossed. However, in one mode of the present disclosure, the present invention is not necessarily limited to this, and the first direction and the second direction may not be orthogonal to each other. For example, when the flat sheet 3 is formed of a parallelogram, the plurality of protrusions 10 are in a first direction parallel to one side of the parallelogram and a second direction parallel to the other side of the parallelogram. It can be assumed that they are erected in an array array. In this case, the first direction and the second direction form an array that is not orthogonal. The first direction and the second direction may not be along the side of the flat sheet 3.

Further, as shown in FIG. 2, the plurality of protrusions 10 of the present embodiment are regularly erected on the flat sheet 3, so that the gaps d1 between the protrusions 10 and 10 facing each other are in the vertical direction. It is designed to grow straight. For this reason, the hair sample M is placed on the flat sheet 3 so as to extend straight in the gap d1. Then, the hair sample M placed on the flat sheet 3 is brought into contact with the protrusions 10 and 10 facing the both sides of the hair sample M so that the movement is suppressed except for the movement along the longitudinal direction which is the first direction. It has become so.

Here, the dimension of the gap d1 between the protrusions 10 and 10 is approximately the same as the thickness of the hair sample M, that is, the thickness of the hair sample M. Specifically, the dimension of the gap d1 is, for example, about 50 to 150 μm.

The dimension of the gap d1 may be the same as the dimension of the tip of the projection 10 and the dimension of the base of the projection 10, or the dimension of the tip of the projection 10 is larger than the dimension of the root of the projection 10. May spread. Alternatively, the base dimension of the protrusion 10 may be narrower than the thickness of the hair sample M. In this case, the hair sample M can be held by being pushed into the bases of the protrusions 10. Further, as described in the second embodiment, the size of the gap d1 of the protrusion 10 is 150 to 1000 μm at the base of the protrusion 10 and 50 to 150 μm at the upper end that is the tip of the protrusion 10. It may be narrowed. In this case, 150 μm at the upper end, which is the tip of the protrusion 10, indicates the dimension when it is narrower than the base dimension of the protrusion 10. Thereby, the space | interval of the upper end of the protrusion 10 is pushed wide by pressing the hair sample M from the upper side of a pair of protrusion 10 * 10. For this reason, the hair sample M is moved downward to the base of the protrusion 10, and the hair sample M is held between the protrusions 10. Further, the protrusion 10 may be formed integrally with the planar sheet 3 or may be implanted in the planar sheet 3. Further, the protrusion 10 may be formed on the base sheet 2 and may protrude through the flat sheet 3 through the flat sheet 3.

As the material of the protrusion 10, for example, cotton, plastic, resin, rubber, metal, carbon fiber, or the like can be used. Moreover, it is preferable that the protrusion 10 has a little elasticity. However, the protrusion 10 is not a material attached to the hair sample M.

Furthermore, in order to hold the hair sample M, the length, that is, the height of the protrusion 10 needs to be at least about the thickness of the hair sample M. Specifically, for example, about 50 to 3000 μm is preferable.

Next, in the hair sample jig 1A of the present embodiment, a mark 20 indicating the cutting position of the hair sample M is displayed on at least an end portion of the upper surface of the flat sheet 3. In the present embodiment, a plurality of hair samples M collected and fixed to the planar sheet 3 are desired to be integrated with the planar sheet 3 in parallel to the lateral direction that is a direction orthogonal to the length direction of the hair sample M. It is cut every length. As a mark of this desired length, the mark 20 of the present embodiment is the cutting of the hair sample M in the first direction at least at the end portion of the flat sheet 3 as shown in FIGS. The position is indicated.

Here, in FIG. 3A, the mark 21 is provided on the outside of the flat sheet 3 where the protrusions 10 stand, and is provided at the end of the flat sheet 3 as, for example, a triangular mark. This mark 21 indicates the cutting position of the hair sample M in the longitudinal direction which is the first direction. Thus, when the hair samples M respectively fixed on the projections 10 and 10 facing each other and linearly extending in a plurality of longitudinal directions are respectively cut on the flat sheet 3, along the mark 21. Each hair sample M can be cut.

Here, the mark 21 of the present embodiment is provided at the end of the flat sheet 3 on the surface of the flat sheet 3, but not limited to this, for example, when the flat sheet 3 has a thickness. As shown in FIG. 3B, it is possible to provide a mark 22 on the side surface of the flat sheet 3.

Further, the mark 20 is not necessarily provided only at the end of the flat sheet 3. A configuration of a modification of the mark 20 of the present embodiment will be described based on FIGS. 4 (a), 4 (b), and 4 (c). FIG. 4A is a plan view showing a mark 23 which is a modification of the mark 20 in the hair sample jig 1A. FIG. 4B is a plan view showing a mark 24 which is another modification of the mark 20 in the hair sample jig 1A. FIG. 4C is a plan view showing a mark 25 which is still another modified example of the mark 20 in the hair sample jig 1A.

As shown in FIG. 4 (a), it is possible to draw a plurality of broken lines, for example, extending as a mark 23 in the lateral direction of the flat sheet 3. The broken line extends to the end portion of the flat sheet 3 and the protrusion 10 does not exist at the end portion of the flat sheet 3, so that the mark 23 can be easily recognized. Thus, as the mark 23, when the flat sheet 3 is cut by extending in the lateral direction of the flat sheet 3 and drawing a plurality of broken lines, for example, the flat sheet 3 can be cut along the broken lines. Cutting work becomes easy.

Further, as shown in FIG. 4B, as the mark 24, it is possible to draw a plurality of, for example, broken lines in the horizontal direction of the flat sheet 3 and color-code each region partitioned by the mark 24. . This color coding also extends to the end of the flat sheet 3, and the protrusions 10 are not present at the end of the flat sheet 3, so that the mark 24 can be easily recognized. Moreover, since the hair sample M can be shown as a color-coded region in the longitudinal length direction, the hair sample M can be easily identified in the length direction. From the viewpoint of identifying the hair sample M in the length direction, it is also possible to attach a sequence number to each region.

Further, as shown in FIG. 4C, a mark 23 made of a broken line on the surface of the flat sheet 3 shown in FIG. 4A can be displayed as a mark 25 on the back surface of the base sheet 2. is there. This mark 25 may be used together with the mark 23 shown in FIG. 4A, or may not be used together. This also makes it possible to recognize the cut portion of the flat sheet 3 without being disturbed by the protrusions 10.

That is, in (a), (b), and (c) of FIG. 4, at least the end of the flat sheet 3, that is, the end of the flat sheet 3 that is the outermost row of the protrusions 10 in the group of protrusions 10 24 is provided, and marks 23 to 25 are also provided in other places. As described above, if the marks 23 and 24 are provided at least at the end of the flat sheet 3, the position at which the flat sheet 3 is cut can be specified, and therefore the shape and method of the marks for other portions are not limited.

A method of using the hair sample jig 1A will be described with reference to FIG. FIG. 5 is a plan view showing an installation example of the hair sample M in the hair sample jig 1A.

As shown in FIG. 5, in the hair sample jig 1 </ b> A of the present embodiment, for example, two sets of a plurality of hair samples M having different collection times are accommodated. In this case, the site | part of the time when the hair sample M was extended can be arranged according to a horizontal direction. Specifically, for example, on the left side of FIG. 5, for example, five hair samples M are marked on the mark 20 between the protrusion 10 in the first row from the lower side of FIG. 5 and the second row from the lower side. The hair sample M is straightly fixed in the vertical direction with the ends of the same. As a result, the hair sample M is prevented from shifting in the lateral direction by the protrusions 10 and 10 facing each other, and therefore, the hair sample M is not displaced in the lateral direction in FIG.

In this case, since the hair sample M can be easily moved in the vertical direction, the ends of the five hair samples M can be easily aligned at the position of the mark 20. Even if the ends of the five hair samples M are intended to be aligned with the mark 20, but they are not exactly uniform, in the present embodiment, the hair sample M is not adhered, and therefore, it is easily corrected. It is possible.

Next, on the right side of FIG. 5, for example, the ends of four hair samples M are located at the positions of the marks 20 indicating between the protrusions 10 in the third row from the lower side of FIG. 5 and the fourth row from the lower side. The hair sample M is straightly fixed in the vertical direction with the portions aligned. By doing in this way, about the hair sample M from which the collection | collection time differs, the site | part of the time when the hair sample M extended can be arranged according to a horizontal direction easily. For example, it is assumed that the hair sample M shown on the right side of FIG. 5 is 1.5 months earlier than the hair sample M shown on the left side of FIG. Here, when the hair sample M is human hair, it generally extends 1 cm per month. Therefore, in this case, the hair sample M of the group shown on the right side of FIG. 5 is fixed with an interval of d2 = 1.5 cm as compared with the hair sample M of the group shown on the left side of FIG.

Thus, the hair sample M of the group shown on the left side of FIG. 5 and the hair sample M of the group shown on the right side of FIG. 5 are in a state in which the portions of the hair sample M at the same time are arranged side by side in each hair sample M. ing. Therefore, for example, when the flat sheet 3 is cut along the mark 20 between the protrusion 10 in the tenth row from the lower side of FIG. 5 and the eleventh row from the lower side, the hair sample extending at the same time It becomes possible to collect M together.

When cutting the hair sample M, the hair sample M and the flat sheet 3 are cut along the mark 20 in a direction perpendicular to the length direction of the hair sample M. The fragmented hair sample M is held on the divided flat sheet 3. Therefore, the hair sample fragment can be easily stored. Further, when collecting the hair sample fragment, only the desired divided flat sheet 3 can be separated to collect the hair sample fragment.

In addition, the fragmented hair sample M can be easily separated from the flat sheet 3 without sticking by picking it with tweezers or the like, and a predetermined measurement or the like can be performed. As a result, conventionally, since an adhesive or a pressure-sensitive adhesive has been applied to the sheet, the work of attaching the hair sample to the sheet or adjusting the position of the hair sample M on the sheet is not easy and laborious. However, this is not the case with the hair sample jig 1A of the present embodiment. In addition, when collecting a fragment of the hair sample M that has been cut to a desired length, the hair sample fragment is not peeled off from the pressure-sensitive adhesive sheet as in the prior art, so that the collection operation is easy. Further, it is not necessary to clean the cut hair sample M with an adhesive for the subsequent process.

As described above, in the hair sample jig 1A of the present embodiment, a plurality of collected hair samples M are fixed to the flat sheet 3 as the first sheet and cut to a desired length. On the flat sheet 3, a plurality of protrusions 10 are erected in an array of a vertical direction as a first direction and a horizontal direction as a second direction. The hair sample M is placed on the flat sheet 3 in a state where the hair sample M is linearly extended in a plurality of vertical directions between the plurality of projections 10 erected in an array, so that the projections 10 face each other. -10 suppresses movement except for movement along the vertical direction. A mark 20 indicating the cutting position of the hair sample M in the vertical direction is displayed at least at the end of the flat sheet 3.

As a result, a plurality of collected hair samples M can be placed and fixed on the flat sheet 3 without using an adhesive.

Further, in the hair sample jig 1A in the present embodiment, a mark 20 indicating the cutting position of the hair sample M in the vertical direction is displayed at least at the end of the flat sheet 3. For this reason, when each hair sample M fixed on the projection 10 and linearly extending in a plurality of longitudinal directions is divided, the hair samples M are cut along the marks 20. Can be cut.

Further, the divided flat sheet 3 includes a plurality of hair samples M having a common dividing unit. Therefore, since the plurality of hair samples M can be arranged in a common division unit, the hair sample M can be easily managed.

Furthermore, when any one hair sample M is adopted from the flat sheet 3 including a plurality of hair samples M having a common dividing unit, the hair sample M is not fixed with an adhesive. The hair sample can be picked and removed with tweezers. Furthermore, since no adhesive is attached to the hair sample M, it is easy to handle the hair sample taken out.

Therefore, it is possible to provide a hair sample jig 1A that can fix the hair sample M to the flat sheet 3 without using an adhesive and can easily cut a plurality of hair samples M to a predetermined length. . That is, even if the hair sample M is not fixed to the flat sheet 3 with an adhesive or an adhesive, the hair sample M can be fixed to the flat sheet 3 without any trouble by adopting the configuration of the hair sample jig 1A of the present embodiment. It is possible to provide a hair sample jig 1A that can be easily handled.

In the hair sample jig 1A in the present embodiment, the base sheet 2 is laminated on the back side of the flat sheet 3 so as to be separable from the flat sheet 3. Further, at least the flat sheet 3 of the flat sheet 3 and the base sheet 2 can be cut along the horizontal direction at the display position of the mark 20. In addition, it is preferable that the adhesion accompanying the lamination of the base sheet 2 and the flat sheet 3 is performed by, for example, adhesion. Thereby, it can laminate | stack so that it can isolate | separate easily.

As a result, for example, the base sheet 2 and the flat sheet 3 are at least the maximum length of the hair sample M, and the flat sheet 3 is cut along the horizontal direction at the display position of the mark 20 at a desired length. The flat sheet 3 can be separated from the base sheet 2 and handled in units of division in the sheet 3. After that, the flat sheet 3 of the division unit can be fixed to the original position of the base sheet 2 again.

Therefore, since the plurality of flat sheets 3 cut by the division unit can be held on the single base sheet 2, the handling and management of the plurality of flat sheets 3 cut by the division unit are facilitated.

In other words, in the hair sample jig 1A of the present embodiment, the protrusions 10 are arranged in an orderly manner on the plane of the flat sheet 3, and the hair sample M is in contact with the protrusions 10 between the protrusions 10 and 10. To fix. At this time, the protrusions 10 are arranged so that the gaps between the protrusions 10 about the thickness of the hair sample M extend straight in the length direction of the hair sample M. As a result, the hair sample M is straightly fixed on the flat sheet 3 and the hair sample M is not displaced laterally. Further, since the hair sample M can be easily shifted in the length direction of the hair sample M, the starting point position of the hair sample M fixed on the flat sheet 3 is once aligned or shifted to a desired position. Can be easily done. Further, after collecting the hair sample fragment after cutting the hair sample M to a desired length, the fragment of the flat sheet 3 cut together with the hair sample fragment is picked up, and the hair sample fragment at the desired site is picked up. It can be collected every time.

[Embodiment 2]
The following describes another embodiment of the present disclosure with reference to FIGS. 6 and 7. The configurations other than those described in the present embodiment are the same as those in the first embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of the first embodiment are given the same reference numerals, and explanation thereof is omitted.

In addition to the configuration of the hair sample jig 1A of the first embodiment, the hair sample jig 1B of the present embodiment is different in the shape of the protrusions.

The configuration of the hair sample jig 1B according to the present embodiment will be described with reference to FIGS. FIGS. 6A to 6F are side views showing the shapes of the protrusions 11 to 16 of the hair sample jig 1B in the present embodiment. 7A to 7F are cross-sectional views showing a state in which the hair sample M is fixed by the pair of protrusions 11 to 16 in the hair sample jig 1B.

In the hair sample jig 1B of the present embodiment, as shown in FIGS. 6A to 6F, various shapes of protrusions can be adopted as the protrusions.

For example, as shown in FIG. 6 (a), it is possible to form a cylindrical projection 11 which is erected perpendicularly to the flat sheet 3 and has the same diameter from the root to the tip. In this case, as shown in FIG. 7A, the gap d4 between the protrusions 11 and 11 facing each other is the same from the root to the tip of the protrusion 11. In the present embodiment, for example, the diameter d3 of the hair sample M and the gap d4 between the protrusions 11 and 11 are the same.

Further, for example, as shown in FIG. 6 (b), it is possible to form a cylindrical projection 12 that is erected on the flat sheet 3 and has the same diameter from the root to the tip. In this case, as shown in FIG. 7 (b), the hair sample M having a diameter d3 is sandwiched at the roots of the opposing protrusions 12 and 12, but the gap d5 at the upper end of the protrusions 12 and 12 is It is narrower than the diameter d3 of the hair sample M. For this reason, the movement of the hair sample M in the lateral direction and the upward direction is suppressed by the protrusions 12. However, since the protrusion 12 has elasticity, when the hair sample M is accommodated in the protrusions 12 and 12 in the gap d5 at the upper end, the protrusion 12 that accommodates the hair sample M by pushing the hair sample M in.・ It can be accommodated at the base of 12 pieces.

Further, for example, as shown in FIG. 6C, the columnar protrusion 13 can be widened toward the upper end. In this case, as shown in FIG. 7 (c), a hair sample M having a diameter d3 is sandwiched at the roots of the opposing protrusions 13 and 13, but the gap d5 at the upper end of the protrusions 13 and 13 is It is narrower than the diameter d3 of the hair sample M. For this reason, the movement of the hair sample M in the lateral direction and the upward direction is suppressed by the protrusions 13. However, since the protrusion 13 has elasticity, when the hair sample M is accommodated in the protrusions 13 and 13 in the gap d5 at the upper end, the protrusion 13 that accommodates the hair sample M by pushing the hair sample M in.・ It can be accommodated at the base of 13.

Further, as shown in FIGS. 7D to 7F, similarly, the protrusions 14 to 16 in which the gap d5 at the upper end is narrower than the gap at the root can be made closer to the upper end. In this case, as shown in FIG. 6 (d), the protrusion 14 is formed in a ring shape, or as shown in FIG. 6 (e), the protrusion 15 is formed in a wedge shape having a step on the side surface. Further, the protrusion 16 can be formed in a hook shape that bends at the upper end side. In the case of the protrusion 16, by making the upper end hook-like, the gap d <b> 5 between the protrusions 16 and 16 adjacent to each other is higher than the height position where the hair sample M is fixed. Becomes narrower. As a result, it is difficult for the hair sample M to come out upward.

When pulling out a hair sample piece that has been cut to a desired length, the distance between the protrusions is increased by the force of pulling up the base sheet with tweezers or the like.

Each of the protrusions 14 to 16 has a hair sample M having a diameter d3 sandwiched between the protrusions 14 to 16, but the gap d5 at the upper end of the protrusions 14 to 16 is narrower than the diameter d3 of the hair sample M. . For this reason, the movement of the hair sample M in the lateral direction and the upward direction is suppressed by the protrusions 14 to 16. However, since the protrusions 14 to 16 have elasticity, when the hair sample M is accommodated in the protrusions 14 to 16 in the gap d5 at the upper end, the protrusion that accommodates the hair sample M by pushing in the hair sample M. It can be accommodated in the roots of the objects 14-16. That is, when the hair sample M is fixed to the flat sheet 3 from above, a narrow gap d5 between the protrusions 14 to 16 is widened by the force of pressing the hair sample M downward. It is possible to reach the vicinity of the upper surface. Further, when pulling out a hair sample fragment cut to a desired length, the gap d5 between the protrusions 14 to 16 is pushed and widened by pulling it up above the flat sheet 3 with tweezers or the like. Can be pulled out.

As described above, in the hair sample jig 1B in the present embodiment, the gap between the protrusions 12 to 16 facing the both sides of the hair sample M is the gap on the root side of the protrusions 12 to 16. The upper end gap d5, which is the gap on the tip side, is narrower than the diameter d3.

Further, in the hair sample jig 1B in the present embodiment, the gap on the root side between the protrusions 11 to 16 facing the both sides of the hair sample M is the same as the thickness of the hair sample M. In addition, you may be narrower than the thickness of the hair sample M.

Further, among the plurality of protrusions 11 to 16, the shortest dimension of the gap between two adjacent protrusions 11 to 16 is 50 to 150 μm.

As a result, the hair sample M is placed on both sides by being placed on the flat sheet 3 while being linearly extended in a plurality of vertical directions between the plurality of protrusions 12 to 16 erected in an array. The movements are suppressed by the protrusions 12 to 16 facing each other except for the movement along the vertical direction. That is, there is no deviation in the horizontal direction. Further, the protrusions 12 to 16 facing the both sides of the hair sample M are narrower in the gap d5 at the upper end, which is the gap on the tip side, than the diameter d3 of the hair sample M, which is the gap on the root side. In the hair sample M, the movement of the protrusions 12 to 16 from the root side to the tip side is also suppressed. In other words, by being sandwiched between the protrusions 12 to 16 extending upward from the flat sheet 3, the hair at the place where the protrusions 12 to 16 and the hair sample M are in contact with each other and the shape of the protrusions 12 to 16 are used. The sample M does not easily escape upward. As a result, the hair sample jig 1B can reliably hold the hair sample M on the flat sheet 3, and for example, can hold the hair sample M without dropping even if the top and bottom are inverted. .

The divided sheets 3a, 3b, 3c and the base sheet 2 may not be separated from each other. In this case, the base sheet 2 is cut together when the hair sample M is cut.

The lengths of the divided sheets 3a, 3b, and 3c in the vertical direction can be the same as the length of cutting the hair sample M, or can be a maximum of about 5 mm shorter than the length of each of the divided hair samples M. is there. For this reason, the fragment of the cut hair sample M is the same as the length in the vertical direction of each of the divided sheets 3a, 3b, and 3c, or slightly separated from the divided sheets 3a, 3b, and 3c. • Hold on 3c.

As a result, the lengths of the divided sheets 3a, 3b, and 3c are determined in advance to create the divided sheets 3a, 3b, and 3c, and are arranged on the base sheet 2 to place the divided sheets 3a, 3b, and 3c. By cutting only the hair sample M, it is possible to create a fragment of a desired length. Therefore, cutting becomes easy.

Further, by making the length of the divided sheets 3a, 3b, and 3c in the vertical direction shorter than the length of the fragment of the hair sample M, the edge of the cut hair sample M protrudes outside the 3a, 3b, and 3c. Therefore, it becomes easy to pick up and collect fragments of the hair sample M.

As described above, in the hair sample jig 1C according to the present embodiment, the flat sheet 3 is composed of the divided sheets 3a, 3b, and 3c divided into a plurality of pieces, and each of the divided sheets 3a, 3b, and 3c is a base sheet. 2, the hair sample M is laminated with a gap in the extending direction, and a mark 20 is displayed between the divided sheets 3 a, 3 b, and 3 c.

Thereby, the hair sample M is linearly extended in the vertical direction as a plurality of first directions between the plurality of protrusions 10 erected in an array shape, and is divided into the plurality of divided sheets 3a, 3b, and 3c. The movements are suppressed except for the movement along the vertical direction by the protrusions 10 and 10 facing each other by being placed with the intervals d6 and d7, respectively. Further, since the mark 20 is displayed between the divided sheets 3a, 3b, and 3c, the hair sample M can be cut into the divided sheets 3a, 3b, and 3c along the mark 20. In this case, since the protrusion 10 does not exist in the cutting position, the hair sample M can be easily cut for each of the divided sheets 3a, 3b, and 3c. Further, when the fragment of the hair sample M divided for each of the divided sheets 3a, 3b, and 3c is collected, the ends of the hair sample M are protruded from the divided sheets 3a, 3b, and 3c. By picking the end of the sample M, the fragment of the hair sample M can be easily recovered.
