PROBLEM TO BE SOLVED: To provide a muscle hardness meter capable of exactly measuring a muscle hardness by suppressing influences of noise produced suddenly.SOLUTION: The muscle hardness meter 1 includes: a contact 4 which is driven by a driving means 3, thereby pressing an object to be pressed 20 a moving distance detecting means for detecting a moving distance X of the contact 4 a press force detecting means 5 for detecting a press force F acting on the contact 4 a calculating means for calculating an integration value W of the press force F in regard to the moving distance X, and a variation value in an elastic modulus k on the basis of each detected value and a control means which uses the integration value W as an index of the muscle hardness when the variation value in the elastic modulus k becomes a prescribed saturation value or less. Since the integration value W is used as the index of the muscle hardness, the muscle hardness can be exactly measured in such the state that the influences of the noise produced suddenly is suppressed.COPYRIGHT: (C)2010,JPO&INPIT【課題】 突発的に生じたノイズによる影響を抑制して、正確な筋硬度を測定できる筋硬度計を提供する。【解決手段】 筋硬度計1は、駆動手段3により駆動して被押圧体20を押圧する接触子4と、接触子4の移動距離Xを検出する移動距離検出手段と、接触子4に作用する押力Fを検出する押力検出手段5と、各検出値から弾性率kの変化量および移動距離Xに対する押力Fの積分値Wを演算する演算手段と、弾性率kの変化量が所定の飽和値以下になった際の積分値Wを筋硬度の指標にする制御手段と、を有するものである。そして、該積分値Wを筋硬度の指標としたことで、突発的に生じたノイズの影響を抑制した正確な筋硬度測定ができる。【選択図】 図1
