Description

毛髪整列方法及び毛髪整列治具Hair alignment method and hair alignment jig
　本開示は、複数の毛髪を載置部材上に一方向に整列して並べる毛髪整列方法及び毛髪整列治具に関するものである。本出願は、２０１８年６月１日に出願された日本国特許出願である特願２０１８－１０６５０４号に対して優先権の利益を主張するものであり、それを参照することにより、その内容の全てが本願に含まれる。 The present disclosure relates to a hair alignment method and a hair alignment jig for aligning and arranging a plurality of hairs on a placement member in one direction. This application claims the benefit of priority to Japanese Patent Application No. 2018-106504, filed on June 1, 2018, and the contents of the contents are referred to by referring to it. All are included in this application.
　毛髪は、血液循環によって、体内の生理活性物質を取り込み、蓄積しながら成長する。このため、毛髪は、１本の毛髪の長さ方向に沿う場所により、生理活性物質の濃度が変化している。そこで、１本の毛髪の長さに応じて連続的に生理活性物質の濃度変化を観測することによって、経時的な生理活性物質の濃度変化を特定することが可能になる。 Hair grows while taking in and accumulating physiologically active substances in the body through blood circulation. For this reason, the density | concentration of the bioactive substance is changing with the place along the length direction of one hair in hair. Therefore, by continuously observing the change in the concentration of the physiologically active substance according to the length of one hair, it is possible to specify the change in the concentration of the physiologically active substance over time.
　例えば特許文献１には、毛髪を長軸方向にスライスして、毛髄質が露出したスライス表面の生理活性物質を分析する、毛髪中に蓄積された生理活性物質の解析方法が開示されている。 For example, Patent Document 1 discloses a method for analyzing a physiologically active substance accumulated in hair, in which the hair is sliced in the long axis direction and the physiologically active substance on the surface of the slice where the medulla is exposed is analyzed.
日本国公開特許公報　特開２０１４－０５２３２２号公報（２０１４年３月２０日公開）Japanese Published Patent Gazette, Japanese Patent Laid-Open No. 2014-052322 (published on March 20, 2014)
　ところで、上記従来の特許文献１に開示された毛髪中に蓄積された生理活性物質の解析方法では、毛髪を長軸方向にスライスする場合に、スライドガラスに両面テープを張り付け、その上に毛髪を固定して毛髪を長軸方向にスライスしている。 By the way, in the analysis method of the physiologically active substance accumulated in the hair disclosed in the above-mentioned conventional patent document 1, when slicing the hair in the long axis direction, a double-sided tape is attached to a slide glass, and the hair is placed on the tape. The hair is fixed and sliced in the long axis direction.
　しかしながら、特許文献１に開示された方法では、スライドガラス上に毛髪を並べて固定する際に、並びがばらばらになるという問題を有している。 However, the method disclosed in Patent Document 1 has a problem that when the hairs are arranged and fixed on the slide glass, the arrangements are scattered.
　また、特許文献１に開示された切断方法以外の毛髪の切断方法として、例えば、毛髪を樹脂で包埋することにより、毛髪を固定して、輪切り又は成長軸方向にカットする方法がある。この方法においては、毛髪を樹脂に包埋する際、手動でカットし、根元を基準に長さを揃えてばらばらにならないように束ねて、筒状の物体の中に毛髪を入れて、樹脂を流し込んで硬化させる必要がある。 Further, as a hair cutting method other than the cutting method disclosed in Patent Document 1, for example, there is a method of fixing the hair by embedding the hair with a resin and cutting it in the direction of ring cutting or growth axis. In this method, when embedding the hair in the resin, it is cut manually, bundled so that the length does not fall apart based on the root, put the hair in a cylindrical object, and the resin It must be poured and cured.
　しかし、その状態で、毛髪を輪切り又は成長軸方向にカットする際、手動ゆえに所望の形状にカットすることが困難であるという問題点を有している。 However, in this state, when the hair is cut in the round direction or the growth axis direction, there is a problem that it is difficult to cut into a desired shape because of manual operation.
　この問題の原因は、毛髪の保持及び固定を手動で行うと、毛髪がばらばらになるためである。この状態で、毛髪全体が樹脂で包埋固定された場合、真っ直ぐに毛髪が並んでないので、毛髪の長手方向において中心軸を通る面で切断することが困難となる。 The cause of this problem is that when the hair is held and fixed manually, the hair is separated. In this state, when the entire hair is embedded and fixed with the resin, the hair is not aligned straight, so that it is difficult to cut the hair along the plane passing through the central axis in the longitudinal direction of the hair.
　本開示の一態様は、上記従来の問題点に鑑みなされたものであって、その目的は、毛髪を整列して並べることが可能な毛髪整列方法及び毛髪整列治具を提供することにある。 One aspect of the present disclosure has been made in view of the above-described conventional problems, and an object thereof is to provide a hair alignment method and a hair alignment jig capable of aligning and aligning hair.
　本開示の一態様における毛髪整列方法は、上記の課題を解決するために、複数の毛髪を載置部材上に一方向に並べて載置する載置工程と、少なくとも一対の突起物を表面に形成したシートの該表面を、前記毛髪を介して前記載置部材に押し付ける押付工程と、前記シートの表面を、前記毛髪を介して前記載置部材に押し付けた状態で該シートを前記一方向にスライドさせることにより、前記複数の毛髪を前記少なくとも一対の突起物の間に通して該毛髪を整列させる整列工程とを含むことを特徴としている。 In order to solve the above-described problem, a hair alignment method according to an aspect of the present disclosure forms a plurality of hairs arranged in one direction on a placement member, and forms at least a pair of protrusions on the surface. A pressing step of pressing the surface of the sheet against the mounting member through the hair, and sliding the sheet in the one direction with the surface of the sheet pressed against the mounting member through the hair. An alignment step of aligning the hairs by passing the plurality of hairs between the at least one pair of protrusions.
　本開示の一態様における毛髪整列治具は、上記の課題を解決するために、複数の毛髪が一方向に並べて載置される載置部材と、少なくとも一対の突起物が表面に形成されているシートとを備えていると共に、前記シートは、前記表面を、前記毛髪を介して前記載置部材に押し付けた状態で前記一方向にスライドさせることにより、前記複数の毛髪のそれぞれを前記少なくとも一対の突起物の間に通して該毛髪を整列させるようになっていることを特徴としている。 In order to solve the above-described problem, the hair alignment jig according to one aspect of the present disclosure has a placement member on which a plurality of hairs are placed in one direction and at least a pair of protrusions formed on the surface. And the sheet is slid in the one direction with the surface pressed against the placement member through the hair, whereby each of the plurality of hairs is moved to the at least one pair. It is characterized in that the hair is aligned between the protrusions.

　〔実施の形態１〕
　以下、本開示の実施の形態について図１～図１０に基づいて説明する。 [Embodiment 1]
Hereinafter, embodiments of the present disclosure will be described with reference to FIGS. 1 to 10.
　本開示の一実施形態の毛髪整列方法及び毛髪整列治具は、採取した複数本の毛髪を整列して並べるものである。並べた毛髪は、樹脂で固定された後、例えば長軸方向に切断され、断面における生理活性物質の濃度変化が観測されるものとなっている。具体的には、好適には、毛髪を長軸方向に沿って切断し、切断された毛髪の生理活性物質をイメージ質量分析するときに適用できる。尚、前述した生理活性物質は、例えばアルコール、ホルモン物質、ニコチン量、違法薬物等である。 The hair alignment method and hair alignment jig according to an embodiment of the present disclosure align and arrange a plurality of collected hairs. The arranged hairs are fixed with a resin and then cut, for example, in the long axis direction, and a change in the concentration of the physiologically active substance in the cross section is observed. Specifically, it can be preferably applied when hair is cut along the long axis direction and the physiologically active substance of the cut hair is subjected to image mass spectrometry. The aforementioned physiologically active substances are, for example, alcohols, hormone substances, nicotine amounts, illegal drugs and the like.
　最初に、従来の毛髪整列方法及び毛髪整列治具並びに毛髪の観測方法について、図１６及び図１７の（ａ）、（ｂ）に基づいて説明する。図１６は、従来の毛髪整列方法を示すフローチャートである。図１７の（ａ）は毛髪整列方法を実施するための従来の毛髪整列治具の構成を示すものであって、毛髪を載置した載置台の上方からメッシュを重ねた状態を示す毛髪の短軸方向の断面図である。図１７の（ｂ）は、載置台に毛髪を載置した状態を示す平面図である。 First, a conventional hair alignment method, hair alignment jig, and hair observation method will be described with reference to FIGS. 16 and 17 (a) and (b). FIG. 16 is a flowchart showing a conventional hair alignment method. FIG. 17 (a) shows the configuration of a conventional hair alignment jig for carrying out the hair alignment method, and is a short hair showing a state in which meshes are stacked from above the mounting table on which the hair is mounted. It is sectional drawing of an axial direction. FIG. 17B is a plan view showing a state where the hair is placed on the placing table.
　図１６に示すように、まず、載置台に毛髪を並べる（Ｓ１０１）。具体的には、図１７の（ａ）、（ｂ）に示すように、載置台１０１の溝１０１ａに毛髪１０２が入るようにして、毛髪１０２を載置台１０１に載置する。次に、毛髪１０２を該載置台１０１上で一方向に並ぶように揃えると共に（Ｓ１０２）、頭皮に近いＡ－Ａ線に沿って毛髪１０２を切断する。次いで、その上から多孔性のメッシュ１０３を押し付けた後、メッシュ１０３の上から接着剤を塗布して毛髪１０２を固定する（Ｓ１０３）。毛髪１０２が固定された後、毛髪１０２を長軸方向に切断する（Ｓ１０４）。これにより、毛髪１０２の長軸方向に沿う断面が露出するので、断面方向の状態を観察することができる。 As shown in FIG. 16, first, hairs are arranged on a mounting table (S101). Specifically, as shown in FIGS. 17A and 17B, the hair 102 is mounted on the mounting table 101 so that the hair 102 enters the groove 101 a of the mounting table 101. Next, the hair 102 is aligned so as to line up in one direction on the mounting table 101 (S102), and the hair 102 is cut along the line AA close to the scalp. Next, after pressing the porous mesh 103 from above, an adhesive is applied from above the mesh 103 to fix the hair 102 (S103). After the hair 102 is fixed, the hair 102 is cut in the long axis direction (S104). Thereby, since the cross section along the major axis direction of the hair 102 is exposed, the state of the cross section direction can be observed.
　ところで、毛髪１０２を精度良く観察するためには、載置台１０１に並べられた毛髪１０２は真っ直ぐかつ同一方向を向いていることが好ましい。しかしながら、実際には、毛髪１０２には曲がりやうねり等が発生しているので、溝１０１ａが存在していても、図１７の（ｂ）に示すように、真っ直ぐに並ぶことができないという問題点を有している。 Incidentally, in order to observe the hair 102 with high accuracy, it is preferable that the hairs 102 arranged on the mounting table 101 are straight and face the same direction. However, in reality, since the hair 102 is bent, undulated, etc., even if the groove 101a exists, the hair 102 cannot be arranged straight as shown in FIG. have.
　これに対して、本実施の形態の毛髪整列方法に使用される毛髪整列治具の構成では、この問題点を解決して、毛髪を整列して並べることが可能な毛髪整列方法及び毛髪整列治具を提供するものとなっている。 On the other hand, in the configuration of the hair alignment jig used in the hair alignment method of the present embodiment, the hair alignment method and the hair alignment treatment capable of solving this problem and aligning and arranging the hair are provided. It is intended to provide ingredients.
　本実施の形態の毛髪整列方法に使用される毛髪整列治具１Ａの構成について、図１～図３に基づいて説明する。図１は、本実施の形態における毛髪整列治具１Ａの構成を示す分解斜視図である。図２の（ａ）は、毛髪整列治具１Ａにおける載置台１０Ａの構成を示す平面図である。図２の（ｂ）は、載置台１０Ａの構成を示す断面図である。図２の（ｃ）は、載置台１０Ａに形成された１つの溝１１の構成を示す断面図である。図３は、毛髪整列治具１Ａにおけるシート２０Ａの構成を示す底面図である。 The configuration of the hair alignment jig 1A used in the hair alignment method of the present embodiment will be described with reference to FIGS. FIG. 1 is an exploded perspective view showing a configuration of a hair alignment jig 1A in the present embodiment. FIG. 2A is a plan view showing the configuration of the mounting table 10A in the hair alignment jig 1A. FIG. 2B is a cross-sectional view showing the configuration of the mounting table 10A. FIG. 2C is a cross-sectional view showing a configuration of one groove 11 formed on the mounting table 10A. FIG. 3 is a bottom view showing the configuration of the sheet 20A in the hair alignment jig 1A.
　本実施の形態の毛髪整列治具１Ａは、図１に示すように、複数の毛髪Ｈが一方向に並べて載置される載置部材としての載置台１０Ａと、少なくとも一対の突起物２１及び突起物２２が各毛髪Ｈに対応して表面に形成されているシート２０Ａと、シート２０Ａの上方から該シート２０Ａを押し付けるメッシュ３０とを備えている。 As shown in FIG. 1, the hair alignment jig 1A according to the present embodiment includes a mounting table 10A as a mounting member on which a plurality of hairs H are mounted in one direction, and at least a pair of protrusions 21 and protrusions. The object 22 includes a sheet 20A formed on the surface corresponding to each hair H, and a mesh 30 that presses the sheet 20A from above the sheet 20A.
　本実施の形態の毛髪Ｈは、「被検体に生える毛」を意図している。被検体が人間の場合、毛の例として、頭髪、髭、眉毛、睫毛、鼻毛、耳毛、腋毛、陰毛及び体毛が挙げられる。本実施の形態では、毛髪Ｈとして、例えば人間の頭髪を想定したものとなっている。 The hair H of the present embodiment is intended to be “hair growing on a 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, for example, human hair is assumed as the hair H.
　ここで、生体サンプルとして毛髪を用いることには、生体サンプルとして血液や唾液などを用いることに対して、以下に例示される利点が存在する。
（１）毛髪の採取は非侵襲性であり、容易である。このため、医師又は医療関係者でない者であってもサンプルを採取できる。
（２）他の種類のサンプルに汚染される危険性が低い。例えば、唾液中と血液中とでは生理活性物質のレベルが異なるのが通常であるから、唾液を採取する際に血液が混入すると生理活性物質のレベルを正確に測定することができない。しかし、採取された毛髪は、洗浄により容易に他の種類のサンプル（血液、唾液等）の混入を除くことができる。
（３）生理活性物質の「蓄積量」を測定するのに適している。すなわち、血液、唾液等から測定された生理活性物質のレベルは、サーカディアンリズム、急性の生体反応等が原因となり、サンプル採取時点における生体条件及び環境条件に左右されがちである。これに対し、毛髪の伸長速度は頭髪で１ｃｍ／月程度である。したがって、毛髪Ｈをサンプルとすることにより、「特定の期間に分泌された生理活性物質の蓄積量」を反映した測定値を得ることができる。尚、「生理活性物質」とは、生命活動及び生理機能の維持、調節等に関わる物質を意図する。生理活性物質の具体例としては、ホルモン、神経伝達物質、サイトカイン、ビタミン、酵素、タンパク質、ペプチド等が挙げられる。 Here, the use of hair as a biological sample has the following advantages over the use of blood or saliva 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. In contrast, the elongation rate of hair is about 1 cm / month for hair. Therefore, by using the hair H 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.
　本開示の毛髪Ｈは、例えば、被検体から収集した毛髪Ｈにおける生理活性物質の蓄積量の経時的変化を測定する毛試料として利用される。このため、毛髪Ｈの経時的変化を測定するためには、一本の頭髪等における各部分の性状を測定する必要がある。 The hair H of the present disclosure is used as, for example, a hair sample for measuring a temporal change in the amount of accumulated physiologically active substance in the hair H collected from a subject. For this reason, in order to measure the time-dependent change of the hair H, it is necessary to measure the property of each part in one hair.
　このため、本実施の形態の毛髪整列治具１Ａは、複数の頭髪等の毛髪Ｈを、真っ直ぐ揃えて固定できるものとなっている。 For this reason, the hair alignment jig 1A of the present embodiment can fix a plurality of hairs H such as head hair straightly and fixed.
　尚、本実施の形態の毛髪Ｈは、人間の毛に加えて、人間以外の哺乳類の毛も含まれる。人間以外の哺乳類の例としては、霊長類（サル、類人猿等）、偶蹄類（ウシ、イノシシ、ブタ、ヒツジ、ヤギ等）、奇蹄類（ウマ等）、齧歯類（マウス、ラット、ハムスター、リス等）、ウサギ目（ウサギ等）、食肉類（イヌ、ネコ、フェレット等）等が挙げられる。上述の人間以外の哺乳類は、家畜又は愛玩動物であってもよく、野生動物であってもよい。 Note that the hair H 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.
　次に、載置部材としての載置台１０Ａは、毛髪Ｈを並べて載置して該毛髪Ｈを支持するための支持部材である。したがって、載置部材は、毛髪Ｈを支持できれば、その形状は台、板、シート等に限定されず、また、材料は金属又は樹脂等の毛髪Ｈを支持できるものであればよい。 Next, the mounting table 10A as a mounting member is a support member for supporting the hair H by placing the hair H side by side. Therefore, as long as the mounting member can support the hair H, the shape is not limited to a table, a plate, a sheet, or the like, and the material may be any material that can support the hair H such as metal or resin.
　本実施の形態の載置台１０Ａは、図２の（ａ）、（ｂ）、（ｃ）に示すように、例えば長方形の平面板の表面１１に一方向に延びる溝部１２が形成されている。尚、載置台１０Ａの形状は長方形に限定されず、他の形状であってもよい。 As shown in FIGS. 2A, 2 </ b> B, and 2 </ b> C, the mounting table 10 </ b> A of the present embodiment has a groove 12 extending in one direction on the surface 11 of a rectangular flat plate, for example. In addition, the shape of 10 A of mounting bases is not limited to a rectangle, Other shapes may be sufficient.
　溝部１２は、各毛髪Ｈに対応させて各毛髪Ｈが該溝部１２に嵌り込むことによって、一方向に並べるのを案内する案内溝としての機能を有している。 The groove portion 12 has a function as a guide groove for guiding each hair H to be arranged in one direction by being fitted into the groove portion 12 in correspondence with each hair H.
　溝部１２は１本でもよいが、図２の（ａ）、（ｂ）に示すように、複数本配されていることが好ましい。試料対象としての複数の毛髪Ｈを同時に採取することができるためである。溝部１２を複数形成する場合には、各溝部１２は規則正しく形成されていることが好ましい。例えば、溝部１２同士の間隔ｄを、例えば１５０μｍ～８３０μｍとして規則正しく並んでいることが好ましい。測定者の所望する間隔に毛髪Ｈを配するように毛髪Ｈを移動できるためである。 The number of the groove portions 12 may be one, but it is preferable that a plurality of grooves 12 are arranged as shown in FIGS. This is because a plurality of hairs H as sample objects can be collected simultaneously. When a plurality of groove portions 12 are formed, each groove portion 12 is preferably formed regularly. For example, it is preferable that the gaps d between the groove portions 12 are regularly arranged, for example, at 150 μm to 830 μm. This is because the hair H can be moved so that the hair H is arranged at intervals desired by the measurer.
　また、本実施の形態における毛髪整列治具１Ａのサイズは、載置台１０Ａのサイズにより制限される。取り扱いの容易さを考えると、載置台１０Ａの幅は、１ｃｍ以上、かつ５ｃｍ以下が好ましい。さらに、載置台１０Ａの長さは、６ｃｍ以上、かつ１８ｃｍ以下が好ましい。 In addition, the size of the hair alignment jig 1A in the present embodiment is limited by the size of the mounting table 10A. Considering ease of handling, the width of the mounting table 10A is preferably 1 cm or more and 5 cm or less. Furthermore, the length of the mounting table 10A is preferably 6 cm or more and 18 cm or less.
　例えば、載置台１０Ａの幅が５ｃｍの場合、溝部１２同士の間隔ｄとして１５０μｍ＜ｄ＜８３０μｍの値を採用すれば、載置台１０Ａに設置される溝部１２の本数は凡そ６０本から３３０本程度となる。 ただし、これに限定されるものではない。 For example, when the width of the mounting table 10A is 5 cm, if a value of 150 μm <d <830 μm is adopted as the distance d between the groove portions 12, the number of the groove portions 12 installed on the mounting table 10A is about 60 to 330. It becomes. However, it is not limited to this.
　図２の（ｃ）に示すように、溝部１２の幅Ｗは、例えば８０μｍ～１５０μｍである。また、溝部１２の深さＤは、１０μｍ～９０μｍであり、より好ましくは１０μｍ～５０μｍである。この深さＤとすることによって、例えば、１本の毛髪Ｈが溝部１２に嵌り易くかつ半分程度嵌る状態となるからである。 2 (c), the width W of the groove 12 is, for example, 80 μm to 150 μm. The depth D of the groove 12 is 10 μm to 90 μm, more preferably 10 μm to 50 μm. This is because, by setting the depth D, for example, one hair H can be easily fitted into the groove 12 and can be fitted about half way.
　尚、溝部１２に嵌る毛髪Ｈの本数は１本とは限らない。後述する実施の形態２に示すように、１つの溝部１２に複数の毛髪Ｈが嵌る場合でもよいためである。 Note that the number of hairs H that fit into the groove 12 is not limited to one. This is because a plurality of hairs H may fit into one groove 12 as shown in a second embodiment described later.
　また、本実施の形態では、後述するように、シート２０Ａを、毛髪Ｈを載置した載置台１０Ａとメッシュ３０との間にシート２０Ａを挟んでスライドし、かつシート２０Ａを引き抜くことにより、メッシュ３０で毛髪Ｈを押さえた状態にして、毛髪Ｈを溝部１２に入り込ませて整列させるようになっている。しかし、シート２０Ａを引き抜かない場合には、シート２０Ａに溝部１２は存在しなくてもよい。シート２０Ａの突起物２１及び突起物２２が毛髪Ｈを整列させた状態に保持するためである。 Further, in the present embodiment, as will be described later, the sheet 20A is slid by sandwiching the sheet 20A between the placing table 10A on which the hair H is placed and the mesh 30, and the sheet 20A is pulled out. In the state where the hair H is pressed at 30, the hair H enters the groove portion 12 and is aligned. However, when the sheet 20A is not pulled out, the groove portion 12 may not exist in the sheet 20A. This is because the protrusions 21 and the protrusions 22 of the sheet 20A hold the hair H in an aligned state.
　次に、図１に示すように、本実施の形態のシート２０Ａは、その表面つまり載置台１０Ａ側の面を、毛髪Ｈを介して載置台１０Ａに押し付けた状態で一方向にスライドさせることにより、毛髪Ｈを各少なくとも一対の突起物２１及び突起物２２の間にそれぞれ通して該毛髪Ｈを整列させるようになっている。本実施の形態では、シート２０Ａは樹脂又は金属からなっている。 Next, as shown in FIG. 1, the sheet 20 </ b> A of the present embodiment is slid in one direction with the surface, that is, the surface on the mounting table 10 </ b> A side pressed against the mounting table 10 </ b> A via the hair H. The hair H is arranged between each of the at least one pair of protrusions 21 and protrusions 22 and the hair H is aligned. In the present embodiment, the sheet 20A is made of resin or metal.
　すなわち、図３に示すように、シート２０Ａの表面つまり載置台１０Ａ側の面には、一対の突起物２１及び突起物２２が複数並んで配されている。１列の突起物２１及び突起物２２を見ると、各突起物２１及び突起物２２は線対称となっていると共に、一対の突起物２１及び突起物２２が、図３において右から左に向かって複数組としての例えば８組が配されている。これら８組並んだ１列の突起物２１及び突起物２２群は、それぞれの線対称の中心線Ｃが、シート２０Ａを載置台１０Ａに重ねたときに、平面視において、載置台１０Ａの溝部１２と重なっていることが好ましい。これにより、載置台１０Ａに載置した毛髪Ｈが溝部１２に嵌るように毛髪Ｈを案内することができる。また、このシート２０Ａは、後述するように、突起物２１及び突起物２２が形成された面を載置台１０Ａに向けて押し付けた状態でスライドさせるようになっている。そこで、シート２０Ａをスライドさせるときには、これら８組並んだ１列の突起物２１及び突起物２２群の線対称の中心線Ｃと、載置台１０Ａの溝部１２とが重なるようにしてスライドさせることが好ましい。これにより、測定者の所望する位置に毛髪Ｈを整列させることができる。 That is, as shown in FIG. 3, a plurality of pairs of protrusions 21 and protrusions 22 are arranged side by side on the surface of the sheet 20A, that is, the surface on the mounting table 10A side. Looking at the protrusions 21 and the protrusions 22 in one row, the protrusions 21 and the protrusions 22 are line symmetric, and the pair of protrusions 21 and protrusions 22 are directed from right to left in FIG. For example, 8 sets as a plurality of sets are arranged. These eight groups of one row of projections 21 and projections 22 are arranged so that the respective line-symmetrical center lines C have groove portions 12 of the mounting table 10A in plan view when the sheet 20A is superimposed on the mounting table 10A. It is preferable to overlap. Thereby, the hair H can be guided so that the hair H mounted on the mounting table 10 </ b> A fits into the groove portion 12. Further, as will be described later, the sheet 20A is slid in a state where the surface on which the protrusions 21 and the protrusions 22 are formed is pressed toward the mounting table 10A. Therefore, when the sheet 20A is slid, it is slid so that the line symmetry center line C of the eight rows of the projections 21 and the group of projections 22 arranged in line with the groove portion 12 of the mounting table 10A overlap. preferable. Thereby, the hair H can be arranged in the position which a measurement person desires.
　また、複数の一対の突起物２１及び突起物２２の列は、複数列配置されていることが好ましい。載置台１０Ａに載置される毛髪Ｈの複数本と対応させるためである。この場合、配列の中心線Ｃの間隔ｄは、例えば１５０μｍ～８３０μｍであることが好ましい。載置台１０Ａの溝部１２同士の間隔ｄに合致させるためである。 Moreover, it is preferable that a plurality of rows of the plurality of pairs of protrusions 21 and protrusions 22 are arranged. This is to correspond to a plurality of hairs H placed on the mounting table 10A. In this case, the distance d between the center lines C of the array is preferably 150 μm to 830 μm, for example. This is to match the distance d between the groove portions 12 of the mounting table 10A.
　ここで、本実施の形態の突起物２１及び突起物２２の間隔について、図４の（ａ）、（ｂ）に基づいて説明する。図４の（ａ）は、毛髪整列治具１Ａにおけるシート２０Ａの突起物２１及び突起物２２の構成を示す底面図である。図４の（ｂ）は、突起物２１及び突起物２２の構成を示す側面図である。 Here, the interval between the protrusions 21 and the protrusions 22 according to the present embodiment will be described with reference to FIGS. FIG. 4A is a bottom view showing the configuration of the protrusions 21 and the protrusions 22 of the sheet 20A in the hair alignment jig 1A. FIG. 4B is a side view showing the configuration of the protrusions 21 and the protrusions 22.
　図４の（ａ）に示すように、本実施の形態における毛髪整列治具１Ａでは、シート２０Ａに形成された一対の突起物２１及び突起物２２の間隔は、シート２０Ａを一方向にスライドさせるときの移動方向前方側の間隔をＬ１とし、移動方向後方側の間隔をＬ２とした場合、
　０＜Ｌ２≦Ｌ１
となっている。つまり、移動方向前方側の間隔Ｌ１が移動方向後方側の間隔Ｌ２よりも大きいように非連続なＶ字状（ハの字型）に並んでいることが好ましい。尚、移動方向前方側の間隔Ｌ１が移動方向後方側の間隔Ｌ２と同じ間隔でもよい。これにより、載置台１０Ａに載置された複数の毛髪Ｈが、曲がりやうねり等によって歪んでいたとしても、移動方向前方側の間隔Ｌ１が大きくなっているので、毛髪Ｈを一対の突起物２１及び突起物２２の間に挿入され易い。また、一対の突起物２１及び突起物２２の間に挿入された毛髪Ｈは、一対の突起物２１及び突起物２２に案内されて通路が狭くなるので、曲がりやうねりがなくなり、一方向に真っ直ぐに整列することになる。したがって、毛髪Ｈを効率よく整列させることができる。 As shown in FIG. 4A, in the hair alignment jig 1A according to the present embodiment, the distance between the pair of protrusions 21 and protrusions 22 formed on the sheet 20A causes the sheet 20A to slide in one direction. When the distance on the front side in the movement direction is L1, and the distance on the rear side in the movement direction is L2,
0 <L2 ≦ L1
It has become. That is, it is preferable to arrange in a discontinuous V shape (C shape) such that the distance L1 on the front side in the movement direction is larger than the distance L2 on the rear side in the movement direction. The distance L1 on the front side in the movement direction may be the same as the distance L2 on the rear side in the movement direction. As a result, even if the plurality of hairs H placed on the mounting table 10A are distorted by bending, undulation or the like, the distance L1 on the front side in the movement direction is large, so that the hair H is paired with the pair of protrusions 21. And is easily inserted between the protrusions 22. Further, the hair H inserted between the pair of protrusions 21 and the protrusions 22 is guided by the pair of protrusions 21 and the protrusions 22 and narrows the passage, so that there is no bending or undulation and straightens in one direction. Will be aligned. Therefore, the hair H can be aligned efficiently.
　また、図４の（ｂ）に示すように、本実施の形態における一対の突起物２１及び突起物２２の高さは、均等な大きさ、高さである必要はない。そして、一対の突起物２１及び突起物２２の最大高さをＬ３とし、移動方向後方側の間隔Ｌ２を毛髪１本の太さの寸法とした場合、
　０＜Ｌ３≦Ｌ２
となっている。これにより、一対の突起物２１及び突起物２２の間に２本の毛髪Ｈが重なって並ぶことを防止することができる。 Further, as shown in FIG. 4B, the heights of the pair of protrusions 21 and protrusions 22 in the present embodiment need not be equal in size and height. And when the maximum height of the pair of protrusions 21 and protrusions 22 is L3, and the distance L2 on the rear side in the movement direction is the size of the thickness of one hair,
0 <L3 ≦ L2
It has become. Thereby, it is possible to prevent two hairs H from being overlapped and arranged between the pair of protrusions 21 and protrusions 22.
　また、間隔Ｌ２の寸法、及び最大高さＬ３の寸法を、一例として、
　５０≦Ｌ２≦２００μｍ、
　５０≦Ｌ３≦１５０μｍ
とすることが好ましい。これにより、本実施の形態の効果がより大きく発揮される。すなわち、一対の突起物２１及び突起物２２によって毛髪Ｈを整列させる場合、毛髪Ｈ自体を回転させずに横に移動させることが好ましい。毛髪Ｈが回転すると、捻じれが発生し、真っ直ぐに整列でき難くなるためである。本実施の形態の一対の突起物２１及び突起物２２が毛髪Ｈを側方から押すように一対の突起物２１及び突起物２２を配置することが理想的である。このためには、一対の突起物２１及び突起物２２の最大高さＬ３の下限は、毛髪Ｈの直径の中央値の半分の値（一般的に、５０～１５０μｍの範囲といわれている。）であり、上限は１５０μｍ（太い毛髪Ｈの直径）であることが好ましい。尚、間隔Ｌ２の寸法は、毛髪Ｈの直径の分布に対して、多少のマージンを含んだものとなっている。ただし、間隔Ｌ２の寸法及び最大高さＬ３の寸法は、これらの大きさに限定されるものではない。 Further, the dimension of the interval L2 and the dimension of the maximum height L3 are taken as an example.
50 ≦ L2 ≦ 200 μm,
50 ≦ L3 ≦ 150 μm
It is preferable that Thereby, the effect of this Embodiment is exhibited more largely. That is, when the hair H is aligned by the pair of protrusions 21 and protrusions 22, it is preferable to move the hair H sideways without rotating. This is because when the hair H rotates, twisting occurs, making it difficult to align straightly. It is ideal to arrange the pair of protrusions 21 and protrusions 22 so that the pair of protrusions 21 and protrusions 22 of this embodiment push the hair H from the side. For this purpose, the lower limit of the maximum height L3 of the pair of protrusions 21 and protrusions 22 is half the median of the diameter of the hair H (generally said to be in the range of 50 to 150 μm). The upper limit is preferably 150 μm (the diameter of thick hair H). The dimension of the interval L2 includes a slight margin with respect to the diameter distribution of the hair H. However, the dimension of the interval L2 and the dimension of the maximum height L3 are not limited to these sizes.
　尚、図４（ａ）に示すように、本実施の形態の一対の突起物２１及び突起物２２は、平面形状がそれぞれ台形にてなっている。また、図４（ｂ）に示すように、一対の突起物２１及び突起物２２の高さは、移動方向前方側の高さが移動方向後方側の高さよりも高くなっている。しかし、一対の突起物２１及び突起物２２の平面形状は必ずしも台形に限らず、他の形状とすることも可能である。また、一対の突起物２１及び突起物２２の高さについて、この形状に限らない。本実施の形態の一対の突起物２１及び突起物２２の変形例の構成について、図５の（ａ）、（ｂ）及び図６に基づいて説明する。図５の（ａ）、（ｂ）は、毛髪整列治具１Ａにおけるシート２０Ａの突起物２１及び突起物２２の変形例の構成を示す平面図である。図６は、毛髪整列治具１Ａにおけるシート２０Ａの突起物２１及び突起物２２の変形例の構成を示す側面図である。 In addition, as shown to Fig.4 (a), as for a pair of protrusion 21 and protrusion 22 of this Embodiment, the planar shape is each trapezoid. Moreover, as shown in FIG.4 (b), as for the height of a pair of protrusion 21 and the protrusion 22, the height of the moving direction front side is higher than the height of the moving direction back side. However, the planar shape of the pair of protrusions 21 and protrusions 22 is not necessarily limited to a trapezoidal shape, and may be other shapes. Further, the height of the pair of protrusions 21 and protrusions 22 is not limited to this shape. A configuration of a modified example of the pair of protrusions 21 and protrusions 22 according to the present embodiment will be described with reference to FIGS. FIGS. 5A and 5B are plan views showing configurations of modifications of the protrusions 21 and the protrusions 22 of the sheet 20A in the hair alignment jig 1A. FIG. 6 is a side view showing a configuration of a modified example of the protrusions 21 and the protrusions 22 of the sheet 20A in the hair alignment jig 1A.
　図５（ａ）に示すように、本実施の形態の一対の突起物２１及び突起物２２の平面形状は、例えば、毛髪Ｈに対向する面が円弧状に形成された突起物２１及び突起物２２とすることができると共に、図５の（ｂ）に示すように、平面形状が三角形の突起物２１及び突起物２２とすることができる。これらの構成により、より効率的に線対称に形成された突起物２１及び突起物２２の中心真付近に毛髪Ｈを移動させて溝部１２に揃えることができる。 As shown in FIG. 5A, the planar shape of the pair of protrusions 21 and protrusions 22 according to the present embodiment is, for example, a protrusion 21 and protrusions whose surfaces facing the hair H are formed in an arc shape. 22, and as shown in FIG. 5B, the planar shape may be a projection 21 and a projection 22 having a triangular shape. With these configurations, the hair H can be moved to the vicinity of the center of the protrusion 21 and the protrusion 22 that are more efficiently symmetrical with respect to the line and can be aligned with the groove 12.
　また、突起物２１及び突起物２２の高さは、図６に示すように、一対の突起物２１及び突起物２２の高さは、移動方向前方側の高さが移動方向後方側の高さよりも低くなっているとすることができる。この構成により、毛髪Ｈを、載置台１０Ａの溝部１２の深い位置に案内することが可能となる。 Further, as shown in FIG. 6, the height of the protrusions 21 and the protrusions 22 is such that the height of the pair of protrusions 21 and protrusions 22 is higher on the front side in the movement direction than on the rear side in the movement direction. It can also be said that it is low. With this configuration, the hair H can be guided to a deep position in the groove 12 of the mounting table 10A.
　次に、メッシュ３０は、図１に示すように、網目状の開口が形成されたシートからなっており、シート２０Ａの上側から、該シート２０Ａを押圧すると共に、シート２０Ａがスライドされて、載置台１０Ａから引き抜かれた後に、メッシュ３０の上方から後述する接着剤又は樹脂２を塗布するためのものである。この結果、シート２０Ａは多孔性であることが好ましい。これにより、載置台１０Ａに載置されて一方向に整列された状態の毛髪Ｈを、該整列状態を保持して接着剤又は樹脂２にて固定することが可能となる。本実施の形態では、メッシュ３０は多孔性であるので、隣接する毛髪Ｈの間の隙間にも樹脂２を浸透させることができる。 Next, as shown in FIG. 1, the mesh 30 is made of a sheet having a mesh-like opening, and presses the sheet 20 </ b> A from the upper side of the sheet 20 </ b> A and slides the sheet 20 </ b> A. This is for applying an adhesive or resin 2 described later from above the mesh 30 after being pulled out from the mounting table 10A. As a result, the sheet 20A is preferably porous. Thus, the hair H placed on the mounting table 10A and aligned in one direction can be fixed with the adhesive or the resin 2 while maintaining the aligned state. In the present embodiment, since the mesh 30 is porous, the resin 2 can be penetrated into the gaps between the adjacent hairs H.
　また、メッシュ３０は、毛髪Ｈを押し込むために、ある程度柔軟であることが好ましい。さらに、メッシュ３０には、頭皮から所定の長さで毛髪Ｈを切断するためのスリットを形成しておくことも可能である。 Further, it is preferable that the mesh 30 is flexible to some extent in order to push in the hair H. Further, the mesh 30 can be formed with slits for cutting the hair H from the scalp at a predetermined length.
　上記の樹脂２及び接着剤は、当該分野つまり毛髪の生理物質の測定において、毛髪Ｈの固定のために使用されるものであれば、限定されない。具体的には、アクリル系樹脂又はエポキシ樹脂等である。 The resin 2 and the adhesive are not limited as long as they are used for fixing the hair H in the field, that is, in the measurement of physiological substances of hair. Specifically, an acrylic resin or an epoxy resin is used.
　上述した構成を有する毛髪整列治具１Ａを用いた毛髪Ｈの毛髪整列方法及び毛髪試料作製方法について、図７～図１０に基づいて説明する。図７は、毛髪整列治具１Ａにおける毛髪整列方法及び毛髪試料作製方法を示すフローチャートである。図８は、本実施の形態の毛髪整列方法を示すものであって、毛髪整列治具１Ａを頭皮に当接した状態を示す斜視図である。図９の（ａ）は、本実施の形態の毛髪整列方法を示すものであって、毛髪Ｈを載置した載置台１０Ａに、上方からシート２０Ａ及びメッシュ３０を重ねた状態を示す毛髪Ｈの長軸方向の断面図である。図９の（ｂ）は、シート２０Ａをスライドさせる状態を示す毛髪Ｈの長軸方向の断面図である。図９の（ｃ）は、シート２０Ａをスライドさせる状態を示す毛髪Ｈの短軸方向の断面図である。図１０の（ａ）は、本実施の形態の毛髪整列方法を示すものであって、毛髪Ｈを樹脂２で固定した状態を示す毛髪Ｈの短軸方向の断面図である。図１０の（ｂ）は、樹脂２で固定した毛髪ＨをＢ－Ｂ断面で切断する状態を示す毛髪Ｈの短軸方向の断面図である。図１０の（ｃ）は、樹脂２で固定した毛髪ＨをＢ－Ｂ断面で切断した状態を示す毛髪Ｈの短軸方向の断面図である。図１０の（ｄ）は、樹脂２で固定した毛髪の断面が露出した状態を示す平面図である。 A hair alignment method for hair H and a hair sample preparation method using the hair alignment jig 1A having the above-described configuration will be described with reference to FIGS.

FIG. 10D is a plan view showing a state in which the cross section of the hair fixed with the resin 2 is exposed.
　毛髪試料を作製する場合には、図７に示すように、まず、載置台１０Ａに数本の毛髪Ｈを並べる（Ｓ１）。具体的には、図８に示すように、載置台１０Ａの側面を頭皮に当接させ、載置台１０Ａに数本の毛髪Ｈを載置する。このとき、毛髪Ｈは必ずしも溝部１２に入らなくてもよい。後述するシート２０Ａをスライドさせることにより、毛髪Ｈが溝部１２に入り込むためである。 When producing a hair sample, as shown in FIG. 7, first, several hairs H are arranged on the mounting table 10A (S1). Specifically, as shown in FIG. 8, the side surface of the mounting table 10A is brought into contact with the scalp, and several hairs H are mounted on the mounting table 10A. At this time, the hair H does not necessarily enter the groove portion 12. This is because the hair H enters the groove portion 12 by sliding a sheet 20A described later.
　次に、毛髪Ｈを載置台１０Ａ上で一方向に並ぶように揃える（Ｓ２）。具体的には、図１に示すように、毛髪Ｈが載置された載置台１０Ａの上方からシート２０Ａの突起物２１及び突起物２２が形成された面を押し付け、さらにその上からメッシュ３０を押し付ける。そして、その状態で、例えば、頭皮に近い部分で毛髪Ｈを切断する。 Next, the hair H is aligned so as to line up in one direction on the mounting table 10A (S2). Specifically, as shown in FIG. 1, the surface on which the protrusions 21 and the protrusions 22 of the sheet 20A are formed is pressed from above the mounting table 10A on which the hair H is mounted, and the mesh 30 is further applied from above. Press. In this state, for example, the hair H is cut at a portion close to the scalp.
　次いで、図９の（ａ）、（ｂ）、（ｃ）に示すように、頭皮に近い部分において載置台１０Ａからはみ出ている数本の毛髪Ｈを図示しない挟み具で挟みながら、かつ、メッシュ３０を押し付けた状態で、シート２０Ａをスライドさせる。図９の（ａ）、（ｂ）においては、シート２０Ａを右側にスライドさせる。そして、シート２０Ａを載置台１０Ａより引き抜く。これにより、本実施の形態では、突起物２１及び突起物２２が形成されたシート２０Ａにより、シート２０Ａに載置された毛髪Ｈが溝部１２に入り込んで整列させられる。 Next, as shown in FIGS. 9 (a), (b), and (c), while sandwiching several hairs H protruding from the mounting table 10A in a portion close to the scalp with a clipper (not shown), and mesh With the 30 pressed, the sheet 20A is slid. 9A and 9B, the seat 20A is slid to the right. Then, the sheet 20A is pulled out from the mounting table 10A. Thereby, in this Embodiment, the hair H mounted in the sheet | seat 20A enters the groove part 12, and is aligned by the sheet | seat 20A in which the protrusion 21 and the protrusion 22 were formed.
　次いで、図１に示すように、この状態で、メッシュ３０の上から接着剤又は樹脂２を塗布して毛髪Ｈを固定する（Ｓ３）。具体的には、図１０の（ａ）に示すように、載置台１０Ａとメッシュ３０との間に、樹脂２又は接着剤が充填される。 Next, as shown in FIG. 1, in this state, an adhesive or resin 2 is applied from above the mesh 30 to fix the hair H (S3). Specifically, as illustrated in FIG. 10A, the resin 2 or the adhesive is filled between the mounting table 10 </ b> A and the mesh 30.
　次いで、図１に示すように、毛髪Ｈを長軸方向に切断する（Ｓ４）。具体的には、図１０の（ｂ）に示すように、毛髪ＨをＢ－Ｂ断面に沿って長軸方向に切断する。これにより、図１０の（ｃ）、（ｄ）に示すように、毛髪Ｈの長軸方向に沿う断面が露出するので、断面方向の状態を観察又は測定することができる。 Next, as shown in FIG. 1, the hair H is cut in the major axis direction (S4). Specifically, as shown in FIG. 10B, the hair H is cut along the BB cross section in the major axis direction. As a result, as shown in FIGS. 10C and 10D, the cross-section along the long axis direction of the hair H is exposed, so that the state in the cross-sectional direction can be observed or measured.
　このように、本実施の形態の毛髪整列方法では、複数の毛髪Ｈを載置部材としての載置台１０Ａ上に一方向に並べて載置する載置工程と、少なくとも一対の突起物２１及び突起物２２を表面に形成したシート２０Ａの該表面を、毛髪Ｈを介して載置台１０Ａに押し付ける押付工程と、シート２０Ａの表面を、毛髪Ｈを介して載置台１０Ａに押し付けた状態でシート２０Ａを一方向にスライドさせることにより、複数の毛髪Ｈを少なくとも一対の突起物２１及び突起物２２の間に通して毛髪Ｈを整列させる整列工程とを含む。 As described above, in the hair alignment method of the present embodiment, a placement step of placing a plurality of hairs H side by side on a placement table 10A as a placement member, and at least a pair of protrusions 21 and protrusions. The sheet 20A formed on the surface of the sheet 20A is pressed against the mounting table 10A via the hair H, and the sheet 20A is pressed together with the surface of the sheet 20A pressed against the mounting table 10A via the hair H. An alignment step of aligning the hair H by sliding the hair H between at least the pair of protrusions 21 and protrusions 22 by sliding in the direction.
　また、本実施の形態における毛髪整列治具１Ａは、複数の毛髪Ｈが一方向に並べて載置される載置部材としての載置台１０Ａと、少なくとも一対の突起物２１及び突起物２２を表面に形成されているシート２０Ａとを備えている。シート２０Ａは、表面を、毛髪Ｈを介して載置台１０Ａに押し付けた状態で一方向にスライドさせることにより、複数の毛髪Ｈのそれぞれを少なくとも一対の突起物２１及び突起物２２の間に通して毛髪Ｈを整列させるようになっている。 Further, the hair alignment jig 1A in the present embodiment has a mounting table 10A as a mounting member on which a plurality of hairs H are arranged in one direction, and at least a pair of protrusions 21 and protrusions 22 on the surface. And a formed sheet 20A. The sheet 20 </ b> A is slid in one direction with the surface pressed against the mounting table 10 </ b> A via the hair H, thereby passing each of the plurality of hairs H between at least the pair of protrusions 21 and protrusions 22. The hair H is arranged.
　これにより、毛髪Ｈを載置台１０Ａ上に整列させる場合には、まず、複数の毛髪Ｈを載置台１０Ａ上に一方向に並べて載置する。しかし、実際には、毛髪Ｈにはうねり等が発生しているので、真っ直ぐに一方向に並べることができない。 Thus, when aligning the hair H on the mounting table 10A, first, the plurality of hairs H are arranged in one direction on the mounting table 10A. However, in actuality, the hair H has waviness and the like, so it cannot be arranged straight in one direction.
　そこで、本実施の形態においては、シート２０Ａの表面を、毛髪Ｈを介して載置台１０Ａに押し付けながら、シート２０Ａを一方向にスライドさせる。これにより、シート２０Ａの表面には、少なくとも一対の突起物２１及び突起物２２が形成されているので、複数の毛髪Ｈのそれぞれは少なくとも一対の突起物２１及び突起物２２の間を通る。これにより、各毛髪Ｈは櫛で梳くのと同様に、整列させられる。 Therefore, in the present embodiment, the sheet 20A is slid in one direction while pressing the surface of the sheet 20A against the mounting table 10A via the hair H. Thereby, since at least a pair of protrusions 21 and protrusions 22 are formed on the surface of the sheet 20 </ b> A, each of the plurality of hairs H passes between at least the pair of protrusions 21 and the protrusions 22. Thereby, each hair H is aligned similarly to combing with a comb.
　したがって、毛髪Ｈを整列して並べることが可能な毛髪整列方法及び毛髪整列治具１Ａを提供することができる。また、毛髪Ｈを整列して並べることができるので、ミクロトーム等の専用の切断機械を使用しなくても、毛髪Ｈを成長方向において該毛髪Ｈの中心軸を通る切断面にて容易かつ的確に切断することが可能である。 Therefore, it is possible to provide a hair alignment method and a hair alignment jig 1A capable of aligning and arranging the hair H. Further, since the hair H can be aligned and arranged, the hair H can be easily and accurately formed on the cut surface passing through the central axis of the hair H in the growth direction without using a dedicated cutting machine such as a microtome. It is possible to cut.
　また、本実施の形態における毛髪整列方法では、載置工程においては、載置台１０Ａに形成された案内溝としての溝部１２により複数の毛髪Ｈのそれぞれを一方向に案内して並べる。 Further, in the hair alignment method according to the present embodiment, in the placing step, each of the plurality of hairs H is guided and arranged in one direction by the groove portion 12 as a guide groove formed on the placing table 10A.
　また、本実施の形態における毛髪整列治具１Ａは、載置台１０Ａには、複数の毛髪Ｈのそれぞれを一方向に案内して並べる案内溝としての溝部１２が形成されている。 Further, in the hair alignment jig 1A in the present embodiment, the mounting table 10A is provided with a groove portion 12 as a guide groove for guiding and arranging the plurality of hairs H in one direction.
　これにより、載置台１０Ａには溝部１２が形成されているので、毛髪Ｈを載置台１０Ａに載置してシート２０Ａを一方向にスライドさせたときに、毛髪Ｈがこの溝部１２に案内されて該溝部１２に嵌っていく。したがって、整列された毛髪Ｈが再度乱れるのを抑制することができる。 Thereby, since the groove part 12 is formed in the mounting base 10A, when the hair H is placed on the mounting base 10A and the sheet 20A is slid in one direction, the hair H is guided to the groove part 12. Fit into the groove 12. Therefore, the aligned hair H can be prevented from being disturbed again.
　また、本実施の形態における毛髪整列方法では、整列工程においては、シート２０Ａの載置台１０Ａ側とは反対側の面に接している多孔板としてのメッシュ３０と毛髪Ｈを載置した載置台１０Ａとの間に該シート２０Ａを挟んだ状態で、該シート２０Ａをスライドさせる。 Moreover, in the hair alignment method in this Embodiment, in the alignment process, 10 A of mounting bases which mounted the mesh 30 and the hair H as a perforated board in contact with the surface on the opposite side to the mounting base 10A side of the sheet | seat 20A. The sheet 20A is slid in a state where the sheet 20A is sandwiched therebetween.
　これにより、シート２０Ａをメッシュ３０で略均一に押圧しながら、シート２０Ａをスライドさせることができる。このため、載置台１０Ａに載置された毛髪Ｈが均一に押圧された状態で、溝部１２に嵌り易くなる。 Thereby, the sheet 20A can be slid while pressing the sheet 20A with the mesh 30 substantially uniformly. For this reason, it becomes easy to fit in the groove part 12 in the state in which the hair H mounted on 10 A of mounting bases was pressed uniformly.
　また、本実施の形態における毛髪整列治具１Ａでは、シート２０Ａに形成された一対の突起物２１及び突起物２２の間隔は、シート２０Ａを一方向にスライドさせるときの移動方向前方側の間隔をＬ１とし、移動方向後方側の間隔をＬ２とした場合、
　０＜Ｌ２≦Ｌ１
である。 In the hair alignment jig 1A according to the present embodiment, the distance between the pair of protrusions 21 and protrusions 22 formed on the sheet 20A is the distance on the front side in the movement direction when the sheet 20A is slid in one direction. If L1 and the distance on the rear side in the moving direction is L2,
0 <L2 ≦ L1
It is.
　これにより、一対の突起物２１及び突起物２２の形状は非連続なＶ字状（ハの字型）となっている。この結果、載置台１０Ａに載置された複数の毛髪Ｈが曲がりやうねり等に歪んでいたとしても、移動方向前方側の間隔Ｌ１が大きくなっているので、毛髪Ｈを一対の突起物２１及び突起物２２の間に挿入され易い。また、一対の突起物２１及び突起物２２の間に挿入された毛髪は、一対の突起物２１及び突起物２２に案内されて通路が狭くなるので、曲がりやうねりがなくなり、一方向に真っ直ぐに整列することになる。したがって、毛髪Ｈを効率よく整列させることができる。 Thereby, the shape of the pair of protrusions 21 and protrusions 22 is a discontinuous V-shape (C-shape). As a result, even if the plurality of hairs H placed on the mounting table 10A are distorted to bend or swell, the distance L1 on the front side in the movement direction is large, so that the hair H is made into a pair of protrusions 21 and It is easy to insert between the protrusions 22. Further, since the hair inserted between the pair of protrusions 21 and the protrusions 22 is guided by the pair of protrusions 21 and protrusions 22 and the passage is narrowed, there is no bending or undulation, and the hair is straightened in one direction. Will be aligned. Therefore, the hair H can be aligned efficiently.
　また、本実施の形態における毛髪整列治具１Ａは、一対の突起物２１及び突起物２２の最大高さをＬ３とし、移動方向後方側の間隔Ｌ２を毛髪１本の太さの寸法とした場合、０＜Ｌ３≦Ｌ２である。 In the hair alignment jig 1A in the present embodiment, the maximum height of the pair of protrusions 21 and protrusions 22 is L3, and the distance L2 on the rear side in the movement direction is the size of the thickness of one hair. 0 <L3 ≦ L2.
　これにより、一対の突起物２１及び突起物２２の間に２本の毛髪Ｈが重なって並ぶことを防止することができる。 Thereby, it is possible to prevent the two hairs H from overlapping and aligning between the pair of protrusions 21 and protrusions 22.
　また、本実施の形態における毛髪整列治具１Ａでは、シート２０Ａは、樹脂又は金属からなっている。このため、シート２０Ａに複数の突起物２１及び突起物２２を容易に一体に形成することが可能である。 In the hair alignment jig 1A in the present embodiment, the sheet 20A is made of resin or metal. For this reason, it is possible to easily form a plurality of protrusions 21 and protrusions 22 integrally on the sheet 20A.
　〔実施の形態２〕
　本開示の他の実施の形態について図１１及び図１２に基づいて説明すれば、以下のとおりである。尚、本実施の形態において説明すること以外の構成は、前記実施の形態１と同じである。また、説明の便宜上、前記の実施の形態１の図面に示した部材と同一の機能を有する部材については、同一の符号を付し、その説明を省略する。 [Embodiment 2]
Another embodiment of the present disclosure will be described below with reference to FIGS. 11 and 12. 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.
　前記実施の形態１の毛髪整列治具１Ａにおける載置台１０Ａの溝部１２の形状は、例えば、毛髪Ｈの直径と略同じ寸法の半円形状となっていた。これに対して、本実施の形態における毛髪整列方法及び毛髪整列治具１Ｂで用いられる載置台（載置部材）１０Ｂでは溝部１２の形状が異なっている。 The shape of the groove 12 of the mounting table 10A in the hair alignment jig 1A of the first embodiment is, for example, a semicircular shape having substantially the same size as the diameter of the hair H. On the other hand, in the mounting table (mounting member) 10B used in the hair alignment method and the hair alignment jig 1B in the present embodiment, the shape of the groove 12 is different.
　本実施の形態の毛髪整列治具１Ｂの構成について、図１１の（ａ）、（ｂ）、（ｃ）、（ｄ）及び図１２に基づいて説明する。図１１の（ａ）、（ｂ）、（ｃ）、（ｄ）は、載置台１０Ｂの構成を示す断面図である。図１２は、毛髪整列治具１Ｂにおける載置台１０Ｂの他の変形例の構成を示す断面図である。 The configuration of the hair alignment jig 1B of the present embodiment will be described with reference to FIGS. 11A, 11B, 11C, and 12 and FIG.

　すなわち、本実施の形態の毛髪整列治具１Ｄを用いて、毛髪試料を作製する場合には、図２に示す毛髪Ｈを揃える工程においては、シート２０Ｄをスライドさせるが、シート２０Ｄを載置台１０Ｄから抜き出すことはしない。そして、毛髪Ｈの固定工程（Ｓ３）においては、シート２０Ｄを毛髪Ｈに押し当てながら、シート２０Ｄの樹脂注入孔２５から前記樹脂２を流し込む。これにより、メッシュ３０を使用することなく、毛髪Ｈを樹脂２にて固定することができる。 That is, when a hair sample is prepared using the hair alignment jig 1D of the present embodiment, the sheet 20D is slid in the step of aligning the hair H shown in FIG. 2, but the sheet 20D is placed on the mounting table 10D. Do not pull out from. In the hair H fixing step (S3), the resin 2 is poured from the resin injection hole 25 of the sheet 20D while pressing the sheet 20D against the hair H. Thereby, the hair H can be fixed with the resin 2 without using the mesh 30.
　尚、図１４においては、シート２０Ｄのスライド方向において一対の突起物２１及び突起物２２と隣接する他の一対の突起物２１及び突起物２２との対称軸上に樹脂注入孔２５が穿設されている。これにより、樹脂注入孔２５から樹脂２を流し込む場合に、一対の突起物２１及び突起物２２との対称軸と毛髪Ｈが入り込む溝部１２との平面的な位置は一致しているので、毛髪Ｈを効率よく樹脂２にて固定することができる。 In FIG. 14, a resin injection hole 25 is formed on the symmetry axis of the other pair of protrusions 21 and protrusions 22 adjacent to the pair of protrusions 21 and protrusions 22 in the sliding direction of the sheet 20 </ b> D. ing. As a result, when the resin 2 is poured from the resin injection hole 25, the planar position of the symmetrical axis of the pair of protrusions 21 and protrusions 22 and the groove portion 12 into which the hair H enters is the same. Can be efficiently fixed by the resin 2.
　このように、本実施の形態の毛髪整列治具１Ｄでは、シート２０Ｄには、シート２０Ｄで押し付けられて整列された毛髪Ｈを上方から樹脂２を注入するための樹脂注入孔が穿設されている。これにより、メッシュ３０を使用することなく、毛髪Ｈを樹脂２にて固定することができる。すなわち、本実施の形態の毛髪整列治具１Ｄのシート２０Ｄは、毛髪Ｈを整列させる機能とメッシュ３０との機能とが一体化しているので、部材点数を少なくして、効率よく、毛髪Ｈを固定することができる。 Thus, in the hair alignment jig 1D of the present embodiment, the sheet 20D is provided with a resin injection hole for injecting the resin 2 from the upper side to the hair H pressed and aligned by the sheet 20D. Yes. Thereby, the hair H can be fixed with the resin 2 without using the mesh 30. That is, the sheet 20D of the hair alignment jig 1D according to the present embodiment integrates the function of aligning the hair H and the function of the mesh 30, so the number of members is reduced and the hair H can be efficiently obtained. Can be fixed.
　また、本実施の形態の毛髪整列治具１Ｄでは、メッシュ３０を省略することができるので、シート２０Ｄの突起物２１及び突起物２２の高さを高くすることできる。その結果、例えば、図１５の（ｃ）に示すように、載置台１０Ｄの溝部をなくすことが可能となる。 Further, in the hair alignment jig 1D of the present embodiment, the mesh 30 can be omitted, so that the heights of the protrusions 21 and the protrusions 22 of the sheet 20D can be increased. As a result, for example, as shown in FIG. 15C, the groove portion of the mounting table 10D can be eliminated.
　尚、本開示は、上述した各実施形態に限定されるものではなく、請求項に示した範囲で種々の変更が可能であり、異なる実施形態にそれぞれ開示された技術的手段を適宜組み合わせて得られる実施形態についても本開示の技術的範囲に含まれる。さらに、各実施形態にそれぞれ開示された技術的手段を組み合わせることにより、新しい技術的特徴を形成することができる。 The present disclosure is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined.
