SHEET THICKNESS MEASUREMENT DEVICE AND SHEET THICKNESS ADJUSTMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sheet thickness measurement device capable of accurately measuring a sheet thickness.SOLUTION: A sheet thickness measurement device 10 includes: a measurement displaceable roller 22 that is in contact with a top surface 7b (a second main surface) of a sheet electrode 7 (a sheet-like member) and is displaced according to the thickness of the sheet electrode; a displacement amount measuring section (a main displacement sensor 70, a CPU) that measures the amount of displacement of the measurement displaceable roller; an upstream-side displaceable roller 41 that is disposed on the upstream side of the measurement displaceable roller, is in contact with an undersurface 7a of the sheet electrode, and can be displaced in a thickness direction of the sheet electrode; a spring (an upstream-side elastic member) that is disposed so as to extend and contract with displacement of the upstream-side displaceable roller; an upstream-side fixed roller 42; a downstream-side displaceable roller 61 that is disposed on the downstream side of the measurement displaceable roller, is in contact with the undersurface of the sheet electrode, and can be displaced in the thickness direction of the sheet electrode; a spring (a downstream-side elastic member) that is disposed so as to extend and contract with displacement of the downstream-side displaceable roller; and a downstream-side fixed roller 62.
