<p>PROBLEM TO BE SOLVED: To prevent a discharge roller 202 and slave rollers 204, 207 from being deflected in the transportation direction of a sheet S when the discharge roller 202 rotates forward and backward, relating to a triple roller configuration (a configuration in which two slave rollers 204, 207 are arranged to face discharge roller 202).SOLUTION: In a cross section vertical to the axial direction of the drive roller 202, a rotational center of the discharge roller 202 is provided at a position other than on a straight line connecting the rotational center of the discharge slave roller 204 with the rotational center of the both-sided slave roller 207. Further, the discharge roller 202 which receives a force from the both-sided slave roller 207 and the discharge slave roller 204 is pressed with a discharge roller presser 211.</p> |
