Abstract
In an electrophotographic copier, while a document is transported toward a predetermined position on a glass platen, its lateral dislocation and skew with respect to a document transport path as well as an amount of the dislocation and a direction of the skew are commonly sensed by a single sensor. The single sensor is positioned adjacent to one of laterally opposite ends of the transport path and has sensing surface of a predetermined area. While the document moves past the sensing surface of the sensor, the sensor generates a signal which corresponds to an area of the sensing surface which is occupied by the sheet.
