A reversing device for at least one sheet of paper, intended particularly for inclusion in a scanner in a printing device such as a printer or a copying machine. The reversing device has a first guide for guiding one or more paper sheets along a feed path in a first direction. A roller system is also provided and is disposed downstream from the first guide. The roller system defines a transport nip and comprises at least one driven roller which is adapted to be driven selectively in two opposite directions of rotation for selectively driving the sheet of paper respectively in a second direction and a third direction. The second direction has a component which is in the first direction, and the third direction is opposite to the first direction. A second guide is also provided for guiding the paper sheet in a fourth direction which has a component in the third direction. When moving in the fourth direction, the paper sheet moves along a discharge path which is different from the feed path. The reversing device further comprises an operating device for the second guide which will bring the second guide of and into an operative position for transporting the paper sheet in the second direction and the third direction.
