Abstract: Provided is a control unit of a conveying apparatus, the conveying apparatus including: a conveying unit that conveys recording paper along a conveyance path; an imaging unit that images the recording paper; and a light emitting unit arranged on an opposite side of the imaging unit across the conveyance path, wherein the control unit detects conveyance information of the recording paper based on image information of the recording paper imaged by the imaging unit in a state in which light from the light emitting unit is transmitted through the recording paper. The control unit detects the conveyance information of the recording paper based on a plurality of images of the recording paper imaged at different timings by the imaging unit.
