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 1):
An image scanner comprising:\n a document table configured to support a document; a document cover configured to be opened and closed selectively to change between an open state in which the document cover exposes the document table and a closed state in which the document cover covers the document table; a reader including a line image sensor extending along a main scanning direction, the reader configured to read an image using the line image sensor to generate a plurality of read image data items, wherein the reader is configured to, in response to reading the document supported by the document table, generate, as one of the plurality of read image data items, document data representing a portion of the document, and in response to reading a surface of the document cover in the closed state, generate, as another of the plurality of read image data items, document cover data representing a portion of the document cover; a moving unit configured to move the line image sensor in a sub-scanning direction perpendicular to the main scanning direction; and a controller configured to: in starting processing, start a reading operation for generating the plurality of read image data items by the reader while causing the moving unit to move the line image sensor downstream in the sub-scanning direction; in leading-edge detection processing, detecting, based on read leading-edge image data that consists of some of the plurality of read image data items and is generated by the reading operation executed from a reading start position where the line image sensor is located at the start of the starting processing to a leading-edge area end position located downstream away from the reading start position by a first predetermined distance in the sub-scanning direction, a document leading edge extending with respect to the main scanning direction and two document side edges each extending with respect to the sub-scanning direction; in area defining processing, define, based on the document side edges, a middle area at a middle portion of the document supported by the document table in the main scanning direction and two side areas each between a corresponding one of the document side edges and the middle area and closer to the respective document side edges than to the middle area; and in ending processing:\n in a case where the document leading edge extends parallel to the main scanning direction, apply ending processing for non-skewed document to a target read image data line to end the reading operation, the target read image data line consisting of some of the plurality of read image data items and located downstream from the leading-edge area end position in the sub-scanning direction; and \n in a case where the document leading-edge of the document does not extend parallel to the main scanning direction, apply ending processing for skewed document to the target read image data line to end the reading operation, \n wherein, in the ending processing for non-skewed document, the controller is configured to end the reading operation in response to change of a type of the target read image data line from the document data to the document cover data in all of the middle area and the side areas in the sub-scanning direction; and wherein, in the ending processing for skewed document, the controller is configured to:\n determine, in the middle area and the side areas, sequentially a first change position, a second change position, and a third change position in the sub-scanning direction, at each of which the type of the target read image data line changes from the document data to the document cover data in the sub-scanning direction; \n determine, based on the first change position and the second change position, whether the document supported by the document table has a rectangular shape; and \n based on the determination result as to whether the document supported by the document table has a rectangular shape and the third change position, end the reading operation.
