Zusammenfassung: | An image reading apparatus reads an original image of an original placed on an original tray by a scanner unit. The original is conveyed to a reading position used by the scanner unit from the original tray through a conveyance path. A registration roller pair configured to mechanically correct skew of the original at a time of conveyance of the original is provided on the conveyance path. The image reading apparatus calculates a skew amount at the time of the conveyance of the original based on the original image, and conducts image processing on the original image based on the skew amount, to thereby correct a tilt of the original image. The image reading apparatus stops the conveyance of the original when the absolute value of the skew amount is larger than a first threshold value. |
