Abstract:
An image scanning apparatus includes a distance detector configured to output a detection signal having a value corresponding to a distance in a main scanning direction from a particular position to a side end of a document sheet being conveyed, and a controller configured to store a first position of the document sheet in a conveyance direction when the distance detector outputs a detection signal having a first value corresponding to a first particular distance, store a second position of the document sheet in the conveyance direction when the distance detector outputs a detection signal having a second value corresponding to a second particular distance, and calculate a skew angle of the document sheet based on the first position and the second position.

Claim (Index 1):
An image scanning apparatus comprising:\n a document tray; an image scanner configured to scan an image of a document sheet being conveyed from the document tray, along a main scanning direction; a conveyor configured to convey the document sheet placed on the document tray, in a conveyance direction perpendicular to the main scanning direction; at least one distance detector configured to output a detection signal having a value corresponding to a distance in the main scanning direction from a particular position to a side end of the document sheet being conveyed by the conveyor, the side end being a side of the document sheet that is substantially along the conveyance direction; a storage; and a controller configured to perform:\n a first determining process to determine whether the at least one distance detector has output a detection signal having a first value corresponding to a first particular distance; \n a first storing process to, when determining that the at least one distance detector has output a detection signal having the first value, store into the storage a first position of the document sheet in the conveyance direction relative to an initial position of the document sheet placed on the document tray, the first position being a position of the document sheet at a point of time when the at least one distance detector has output the detection signal having the first value; \n a second determining process to determine whether the at least one distance detector has output a detection signal having a second value corresponding to a second particular distance, the second particular distance being shorter than the first particular distance; \n a second storing process to, when determining that the at least one distance detector has output the detection signal having the second value, store into the storage a second position of the document sheet in the conveyance direction relative to the initial position, the second position being a position of the document sheet at a point of time when the at least one distance detector has output the detection signal having the second value; and \n a skew angle calculating process to calculate a skew angle of the document sheet based on the first position and the second position, the skew angle being an angle, relative to the conveyance direction, of the side end of the document sheet being conveyed by the conveyor.
