Abstract: The hardness tester includes a data obtainer obtaining sample shape data that can specify a shape of a sample; an image capture controller controlling a CCD camera to capture an image of the surface of the sample and obtaining image data of the sample; a matching performer associating the sample shape data obtained by the data obtainer with the image data of the sample obtained by the CCD camera; an indentation former forming an indentation with an indenter in a test position set on the sample shape data after the sample shape data and the image data of the sample have been associated by the matching performer; and a hardness value calculator calculating a hardness value of the sample based on the indentation captured with the CCD camera after the indentation has been formed by the indentation former.

Abstract: A restitution coefficient measuring device measuring a restitution coefficient of a measuring object includes a holder that holds a spherical impact ball colliding with the measuring object with an elastic member, a shooting mechanism for shooting the impact ball held by the holder from the holder toward the measuring object, a speed measuring unit that measures both a collision speed at which the impact ball collides with the measuring object and a restitution speed at which the impact ball bounces from the measuring object, and a computing unit that calculates the restitution coefficient on the basis of the restitution speed with respect to the collision speed. A hole for bleeding air is bored on any side surface of the holder. The elastic member is an independent member replaceable with respect to the holder and is disposed at an end portion of the holder in an axial direction.

Abstract: A control unit shifts an imaging unit relatively with respect to a stage to take an image of a measuring object at a plurality of places by the imaging unit and thereby obtain a plurality of images, and generates a composite image of the measuring object having a range which is wider than an imaging range of the imaging unit by combining the plurality of images. The control unit shifts the imaging unit relatively with respect to the stage such that parts of images adjacent to one another obtained by the imaging unit overlap, and performs an image matching processing that performs image matching of an overlapped portion of the adjacent images. The control unit generates the composite image of the measuring object by joining the adjacent images at a position where the image matching is performed in the image matching processing.
