A sheet transportation device includes a transportation roller driven during operation, a guiding element and an actuation device that is used to switchably affect the interspacing between the transportation roller and the guiding element. In a closed state during operation, a sheet is guided against the driven roller by the guiding element. The sheet transportation device also includes a freely rotatably arranged roller that is positioned in the vicinity of and arranged concentrically relative to the transportation roller. The freely rotatably arranged roller extends in a radial direction beyond a circumferential edge of the transportation roller. A reversing station and a printer can also include a sheet transportation device of this kind.
