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 2):
The image scanner according to  claim 1 ,\n wherein the side areas include a first area and a second area, wherein the first change position is determined in the first area, the first area extends toward the middle area from a first reference point position along the main scanning direction by a second predetermined distance, wherein the first reference point position is on one of the document side edges extending from a location closer to the reading start position than a location from where the other document side edge extends in the sub-scanning direction and indicates a location of the first reference point position in the main scanning direction that corresponds to a location of the leading-edge area end position in the sub-scanning direction, wherein the third change position is determined in the second area, the second area extends toward the middle area from a third reference point position in the main scanning direction by the second predetermined distance, wherein the third reference point position is a location away from the leading edge by a distance obtained by multiplying a distance between the document side edges by a predetermined ratio and on the other of the document side edges extending from the location farther from the reading start position than the location from where the one document side edge extends in the sub-scanning direction, the predetermined ratio is equal to a value obtained by dividing a dimension of a longer side of a standard-sized document by a dimension of a shorter side of the standard-sized document, wherein the second change position is determined in the middle area, the middle area extends upstream and downstream in the main scanning direction by the second predetermined distance with respect to a second reference point position that is a midpoint between the first reference point position and the third reference point position, and wherein, in the ending processing for skewed document, the controller is further configured to execute moving distance calculation processing for calculating a first moving distance based on the third reference point position and the third change position, wherein the controller is further configured to:\n in a case where the controller determines that the document supported by the document table does not have a rectangular shape, end the reading operation in response to determining the third change position; and \n in a case where the controller determines that the document supported by the document table has a rectangular shape, end the reading operation in response to the moving unit moving the line image sensor downward from the third change position by the first moving distance in the sub-scanning direction.
