Abstract: The present invention includes: an image capturer capturing an image of the sample to be measured; an image acquirer acquiring image data of the sample captured by the image capturer; a pattern searcher performing, on the image data of the sample acquired by the image acquirer, pattern searching process using a pattern image selected based on the sample and identifying a position in the image matching the pattern image; a profile extractor extracting a profile of the sample based on the position in the image identified by the pattern searcher; a calculator calculating a hardness measurement position of the sample based on the profile extracted by the profile extractor; and a measurer executing hardness testing on the sample based on the hardness measurement position calculated by the calculator and measuring the hardness of the sample.

Abstract: Indentation tester capable of adjusting vertical-direction positioning drift due to individual differences of an indenter when indenters are switched includes an adjustment mechanism. The adjustment mechanism adjusts relative vertical-direction positions of a displacement sensor movable portion and a displacement sensor fixed portion. The adjustment mechanism includes a first hollow disk having a spiraling surface formed on a bottom surface; and a second hollow disk having a spiraling surface formed on a top surface. The spiraling surface of the second hollow disk has a thread equal to that of the spiraling surface of the first hollow disk. The first hollow disk rests on the second hollow disk such that the bottom surface of the first hollow disk is overlaid on the top surface of the second hollow disk. The first hollow disk and the second hollow disk are capable of rotation on a center axis of an indenter column.

Abstract translation: 当压头被切换时，由于压头的个体差异，能够调节垂直方向定位漂移的压痕测试器包括调节机构。 调整机构调整位移传感器可动部和位移传感器固定部的相对的垂直方向位置。 调整机构包括：第一中空盘，其具有形成在底面上的螺旋面; 以及具有形成在顶面上的螺旋面的第二中空盘。 第二中空盘的螺旋状表面具有与第一中空盘的螺旋面相同的螺纹。 第一中空盘位于第二中空盘上，使得第一中空盘的底表面重叠在第二中空盘的顶表面上。 第一中空盘和第二中空盘能够在压头柱的中心轴线上旋转。
