Abstract
A sheet thickness measuring device includes: an illumination unit that outputs a light that is illuminated into a stack of sheets from a first area defined on one of faces including a top face, a bottom face, and side faces of the stack of sheets; a detection unit that detects a light amount distribution of light entered into the stack of sheets and propagated to a second area through the stack of sheets, the second area defined on one of the side faces of the stack of sheets; and a calculation unit that calculates a thickness of a sheet in the stack of sheets based on the light amount distribution detected by the detection unit.
