Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sheet illumination technique capable of uniformly contributing to the illumination intensity of illumination light by suppressing attenuation of the illumination light from a light source while contributing to space saving. SOLUTION: A roller for winding a sheet S being an illumination object has a roller 1011 composed of a light transmission material conveying the sheet S by being rotated and the light source 102 arranged in the roller 1011 for illuminating at least a part of a region winding the sheet S on the roller 1011 from the inside of the roller 1011.
