Patent ID: 8141872

Claim:
A printing apparatus comprising: a paper discharge roller unit configured to transport a print sheet to a discharge port; a transportation roller unit configured to transport the print sheet to the paper discharge roller unit; a transportation speed determination unit configured to determine a transportation speed at which the transportation roller unit is driven; and a paper discharge roller drive unit configured to drive the paper discharge roller unit at the transportation speed determined by the transportation speed determination unit during the time that the print sheet is being transported by the transportation roller unit, and then drive the paper discharge roller unit at a discharge speed which is determined independently from the transportation speed after the print sheet has left the transportation roller unit while the print sheet is being transported by the paper discharge roller unit, wherein a print sheet sensor is provided between the discharge roller unit and the discharge port, and wherein the paper discharge roller drive unit detects when the print sheet leaves the transportation roller unit on the basis of the detection result by the print sheet sensor, a distance between the transportation roller unit and a sensing position of the print sheet sensor, a length of the print sheet in the transportation direction, and the transportation speed determined by the transportation speed determination unit.
