Claim:
1. An orientation correcting device comprising: a first transporter configured to nip and transport a sheet; a detector configured to detect a tilt of the sheet that is transported by the first transporter; a second transporter configured to nip and transport the sheet that has been transported by the first transporter, the second transporter provided at a location that is downstream from the first transporter in a transport direction of the sheet; a controller configured to control rotation of the first and second transporters to form a flexure in the sheet by causing the sheet that is transported by the first transporter to strike against the second transporter, with the second transporter being stopped by control of the controller when the sheet strikes the second transporter; a transporter shifter configured to move the second transporter in a crossing direction that crosses the transport direction of the sheet in accordance with an amount and a direction of the sheet tilt detected by the detector, with the second transporter being stopped by the controller and the sheet having the flexure formed in the sheet by the controller, a starter, with the second transporter being stopped and the flexure formed in the sheet by the controller, configured to control the second transporter to start transporting the sheet after the transporter shifter has moved the second transporter while nipping the sheet, in the crossing direction to a first position, wherein, after the starter controls the second transporter to transport the sheet, the transporter shifter is configured to start moving the second transporter while nipping the sheet, in the crossing direction from the first position, and wherein in response to the starter controlling the second transporter to transport the sheet, the controller controls the first transporter to disengage from the sheet.
