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 5):
The image scanner according to  claim 4 ,\n wherein the reader is further configured to read the image in a range in which the line image sensor moves by the moving unit from the reading start position to a furthest readable position, and wherein, in a case where, in the ending processing for skewed document, the controller does not determine the third change position in any of one or more target read image data lines that consist of some of the plurality of read image data items included in a range from the leading-edge area end position to the third reference position in the sub-scanning direction, the controller is configured to, in the area defining processing, determine a fourth area (DR4) that extends toward the middle area from a furthest reference position (MCP) by the second predetermined distance in the sub-scanning direction, wherein the furthest reference position is on the document side edge closer to the third area than the other document side edge to the third area and indicates a location of the furthest reference position in the main scanning direction that corresponds to a location of the furthest readable position in the sub-scanning direction; and\n wherein, in a case where, in the ending processing for skewed document, the controller does not determine the third change position in any of the one or more target read image data lines, the controller is configured to, in the ending processing for skewed document:\n determine, in the fourth area, a fourth change position (DP 4 ) at which type of the read image data line changes from the document data to the document cover data in the sub-scanning direction; and \n end the reading operation based on the fourth change position and the determination result as to whether the document has a rectangular shape.
