とを特徴とする厚み計測装置。[Claims for Utility Model Registration] The sheet to be measured is moved while being closely supported by a rotating shaft, and a light-shielding plate is provided parallel to the rotating shaft at a predetermined distance from the surface of the rotating shaft. In a thickness measuring device that measures the thickness of the sheet to be measured by scanning between the surface of the sheet and the light shielding plate with a laser beam, the rotating shaft and the light shielding plate are fixed and held in parallel with a predetermined distance apart. a frame that is movable in parallel with the rotating shaft and the light shielding plate; a laser beam generator that is loaded on the traveling body and generates the laser beam; a reflecting mirror that is controlled to scan between the surface of the rotating shaft and the light shielding plate in the close contact portion of the sheet to be measured; and the laser beam that has passed between the rotating shaft and the light shielding plate. A thickness measurement device comprising: a light receiver that receives light; a counter that measures the time during which the light receiver receives light; and a calculator that calculates the thickness of the sheet to be measured from the output of the counter. Device.
