【発明の詳細な説明】 （産業上の利用分野） この発明は、毛髪の柔軟性を、頭部から毛髪を剪除す
ることなく直接測定可能とする方法及び装置に関する。Description: TECHNICAL FIELD The present invention relates to a method and a device for measuring the flexibility of hair directly without shearing the hair from the head.
（従来の技術） 毛髪は、個人差、年令差、汚れ具合等によってその柔
軟性が異なっており、柔軟性を測定することによって、
毛髪の健康状態の診断に資することが出来る。(Prior Art) Hair has different flexibility depending on individual differences, age differences, stain conditions, etc.
It can contribute to the diagnosis of the health condition of hair.
しかしながら、従来はこのような毛髪の柔軟性を測定
する有効な方法は提案されていなかった。However, hitherto, no effective method for measuring such softness of hair has been proposed.

能にすると共に、毛髪を頭部から剪除することなく直接
測定可能とするものである。(Problems to be Solved by the Invention) The present invention makes it possible to measure the flexibility of hair simply and accurately, and also to directly measure the hair without shearing it from the head.
（問題点を解決するための手段） 上記問題点を解決するために、第１の発明が採った手
段は、流過する作動流体中に流体の流過方向と直交して
毛髪束を装入し、毛髪束の前後における流体の圧力変化
により毛髪の柔軟性を測定するようにしたことを特徴と
する。(Means for Solving the Problems) In order to solve the above problems, the means adopted by the first invention is to insert a hair bundle into the working fluid flowing through at right angles to the flowing direction of the fluid. However, the flexibility of the hair is measured by changing the pressure of the fluid before and after the hair bundle.
又、第２の発明が採った手段は、作動流体を流過させ
る流路と、該流路内に毛髪束を流体の流過方向と直交し
て装入する装入孔と、該装入孔の前後に配設された圧力
センサーとからなることを特徴とする。Further, the means adopted by the second invention is a flow path for allowing a working fluid to flow through, a charging hole for charging a hair bundle in the flow path at a right angle to the flow direction of the fluid, and a charging hole. It is characterized by comprising a pressure sensor arranged before and after the hole.
（作用） 流体の流過方向と直交して毛髪束を装入し、毛髪を流
過方向に彎曲させるために流体が喪失したエネルギー
を、毛髪束の前後における流体の圧力変化により測定す
る。毛髪の柔軟性は、前記流体の喪失エネルギーと相関
しているため、圧力変化を測定することによって毛髪の
柔軟性を知ることが出来る。(Operation) A hair bundle is inserted orthogonally to the flowing direction of the fluid, and the energy lost by the fluid to bend the hair in the flowing direction is measured by the pressure change of the fluid before and after the hair bundle. Since the softness of the hair is correlated with the energy loss of the fluid, it is possible to know the softness of the hair by measuring the pressure change.
（発明の効果） この発明によれば、流体の流路内に流路と直交して毛
髪束を装入し、毛髪の前後における流体の圧力変化を測
定すれば良く、きわめて簡単で且精確に毛髪の柔軟性を
測定することが出来ると共に、毛髪束は剪除することな
く、直接測定出来る。(Effects of the Invention) According to the present invention, it is sufficient to insert a hair bundle in the flow path of the fluid at right angles to the flow path and measure the pressure change of the fluid before and after the hair, which is extremely simple and accurate. The flexibility of hair can be measured, and the hair bundle can be directly measured without shearing.
