Abstract
A sheet conveying apparatus has a reference roller, a detection roller, and a detection sensor. The detection roller can move, and makes contact with the reference roller, facing the reference roller. The detection sensor outputs a signal corresponding to the displacement of the detection roller. The sheet is conveyed to a nip portion of the pair of rollers. At this time, the timing when an edge portion of the sheet being conveyed passes through the nip portion is detected. In response to the timing detected, the thickness of the sheet is detected, based on the signal output from the detection sensor.
