Abstract:
An image scanner includes a document detector configured to, each time line scanning is repeated a predetermined number of times, perform an edge detecting process to detect a position of a lateral side extending in a sub scanning direction from a non-reference corner of a sheet, in the edge detecting process performed for a first time, set a position of the non-reference corner in a main scanning direction as a detection reference position, in the edge detecting process performed for a second or later time, set a previously-detected position of the lateral side in the main scanning direction as the detection reference position, and in each edge detecting process, set a detection range in the main scanning direction on the basis of the detection reference position, and detect a specific pixel corresponding to the lateral side in the main scanning direction within the detection range in the main scanning direction.

Claim (Index 6):
The image scanner according to  claim 5 ,\n wherein the rectangular area includes:\n a central area having an outer end and an inner end in the main scanning direction, the outer end being positioned further outward of the sheet than the inner end in the main scanning direction; \n an outer area positioned further outward of the sheet than the outer end of the central area in the main scanning direction; and \n an inner area positioned further inward of the sheet than the inner end of the central area in the main scanning direction, and \n wherein the document detector is further configured to:\n determine a first density of black pixels in the central area; \n determine a second density of black pixels in the outer area; \n determine a third density of black pixels in the inner area; and \n detect the position of the lateral side based on the first density, the second density, and the third density.
