A paper leaf detecting device includes a plurality of sensors positioned at an oblique angle relative to a transporting direction of leaves of paper, the plurality of sensors being arranged in a single row that extends in a direction orthogonal to the transporting direction of the leaves of paper. The paper leaf detecting device makes it possible to detect information on leaves of paper by using their transportation to scan the leaves of paper in a direction that is orthogonal to the transporting direction. An increase in size in the transporting direction of the leaves of paper is prevented.
