Abstract:
A controller executes area defining processing for defining a middle area and two side areas, and ending processing. In a case where the document leading edge extends parallel to a main scanning direction, the controller executes the ending processing for non-skewed document. In a case where the document leading edge does not extend parallel to the main scanning direction, the controller executes the ending processing for skewed document. In which, the controller determines, in the middle area and the side areas, first, second, and third change positions, respectively, at each of which a type of a target read image data line changes from document data to document cover data, determines, based on the first change position and the second change position, whether a document has a rectangular shape, and ends the reading operation based on the third change position and the determination result as to the document shape.

Claim (Index 4):
The image scanner according to  claim 3 , wherein the controller is further configured to:\n in first distance calculation processing, calculate a first distance by multiplying a distance between the first area and the middle area in the main scanning direction by a value obtained by application of tangent processing to the skewed angle; and in the ending processing for skewed document:\n in a case where a distance between the first change position and the second change position in the sub-scanning direction is equal to the first distance, determine that the document supported by the document table has a rectangular shape, and \n in a case where the distance between the first change position and the second change position in the sub-scanning direction is not equal to the first distance, determine that the document supported by the document table does not have a rectangular shape.
