Abstract
A first line sensor optically reads a first surface of an original in a main scanning direction to obtain first line image data. A second line sensor arranged in parallel to the first line sensor at a predetermined distance optically reads a second surface of the original to obtain second line image data. A tilt detecting unit detects main-scanning coordinates of a first edge and a second edge from the first line image data, detects main-scanning coordinates of a third edge and a fourth edge from the second line image data, and detects a tilt of the original with respect to a sub-scanning direction based on the detected main-scanning coordinates.
