    Abstract: A hardness tester includes a memory storing, as a parts program, definitions of measurement conditions including a coordinate system and test position defined with respect to an image of a standard reference sample; a pattern searcher performing a pattern searching process, with reference to a plurality of samples to be measured, using a pattern image based on the image of the standard reference sample, and detecting a number of samples having a shape identical to that of the standard reference sample, as well as a position and angle of the samples having the identical shape; a pattern definer defining a coordinate system and test position for each of the samples having the identical shape based on the position and angle of each of the samples having the identical shape; and a measurer measuring the hardness of the samples for which the coordinate system and test position have been defined.

    Abstract: A hardness tester enabling a user to form an indentation in a desired test position, capable of performing an accurate hardness test even when center positions of an indenter and a field lens are offset. The hardness tester includes an XY stage displacing a sample stage in a horizontal direction; a CCD camera capturing images of a sample surface via a field lens; a monitor displaying the images; a turret capable of selectively positioning the indenter or the field lens in a predetermined position opposite the sample; a memory storing an amount of horizontal direction offset between the center positions of the indenter and the field lens when positioned in the predetermined position; and a CPU displaying, based on the amount of offset stored in the memory, a mark indicating the center position of the indenter on the monitor when the field lens is positioned in the predetermined position.

    Abstract: The hardness tester includes a plurality of weights; a transmission mechanism transmitting to an indenter a force of gravity acting on the weights; and a test force switching mechanism switching between magnitudes of a test force. The weights include hollow portions running through the weights in a vertical direction; and accommodation portions formed so as to be capable of accommodating the weight directly below. Outside tapered portions are provided to an exterior surface of the weights and inside tapered portions are provided to an interior surface of the accommodation portions. The transmission mechanism includes a shaft member and a weight engagement portion capable of being accommodated by the bottom-most accommodation portion to engage a weight. The weight engagement portion includes a tapered portion engaging the weight to regulate horizontal-direction displacement. A predetermined gap is reserved between the hollow portions and the shaft member.

    Abstract: A hardness tester includes an image acquirer (controller) acquiring an image of a surface (surface image) of a sample captured by an image capturer, an identifier (controller) identifying, based on the surface image of the sample, a non-conformity region inside the image that is unsuitable for the hardness test using predetermined conditions, and a test position definer (controller) defining a test position in an area outside the non-conformity region identified by the identifier.

    Abstract: A hardness tester includes an image acquirer acquiring an image of a surface of a sample captured by an image capturer, a test area definer defining a test area where the hardness test is performed with respect to the image of the surface of the sample displayed by a display which displays the acquired image of the surface, a test setting acquirer acquiring estimated hardness of the sample and test force when the hardness test is performed, an estimator estimating a size of the indentation to be formed on the surface of the sample based on the acquired test force and the estimated hardness, and a display controller displaying an image picture of the indentation to be formed, based on the estimated size of the indentation superimposed on the image of the surface of the sample displayed by the display.
