Abstract
A detecting apparatus for detecting information of at least a portion of a stack of sheet media includes an illuminating unit and a detecting unit. The illuminating unit illuminates a side of the stack of sheet media, or a portion thereof with electromagnetic waves. The detecting unit detects electromagnetic waves transmitted through or reflected by the stack of sheet media, or a portion thereof. The detecting apparatus is adapted to compare information of the electromagnetic waves detected by the detecting unit with information about attenuation of electromagnetic waves due to moisture contained in the sheet medium, and detect information of the moisture content of at least a portion of the stack of sheet media.
