Abstract: An unevenness measuring device for a sheet-shaped material, the device including: a light irradiation unit configured to irradiate a measurement target with illumination light such that the illumination light is partially blocked at the measurement target; a time-delay integration type imaging unit arranged to face the light irradiation unit and configured to receive the illumination light that is irradiated from the light irradiation unit and that is not blocked at the measurement target; a luminance-profile calculation unit configured to calculate a luminance profile in a main-scanning direction from a captured image generated by the imaging unit; an unevenness determination unit configured to determine, based on the luminance profile, whether the sheet-shaped material has a recessed portion and/or a projecting portion; and an unevenness calculation unit configured to estimate, based on the luminance profile, a depth of the recessed portion and/or a height of the projecting portion.

Abstract: The present invention provides a device for evaluating particles in a liquid, which is provided with: a main body member that has a first opening part and a second opening part, which face each other, and an internal hollow part; a first flow path and a second flow path, which are connected to the main body member and are in communication with the hollow part; a first drive member and a second drive member, which are arranged within the hollow part so as to face each other and which are slidable within the hollow part; a drive means which drives the first drive member and/or the second drive member in the facing direction within the hollow part; a liquid supply means which introduces a liquid containing particles into the hollow part through the first flow path; and an imaging means which captures an image of particles within the hollow part through the first opening part or the second opening part. This device for evaluating particles in a liquid is configured such that in cases where the first drive member and the second drive member are observed from the facing direction, the first drive member and the second drive member have portions that are wider than the first flow path and the second flow path.
