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 17):
The non-transitory computer-readable medium according to  claim 16 ,\n wherein the instructions are further configured to, when executed by the processor, cause the processor to perform:\n a third determining process to determine whether the target detector has output a detection signal having a third value corresponding to a third particular distance, the third particular distance being shorter than the second particular distance; \n a position interval calculating process to calculate a position interval based on the first position and the second position, the position interval being equivalent to a distance in the conveyance direction from the second position to a third position of the document sheet in the conveyance direction relative to the initial position, under an assumption that the skew angle of the document sheet being conveyed by the conveyor is not varying, the third position being a position of the document sheet at a point of time when the target detector has output the detection signal having the third value; \n a detection distance calculating process to, when determining that the target detector has output a detection signal having the third value, calculate a detection distance by subtracting the second position from the third position; \n a detection distance determining process to determine whether the detection distance is identical to the position interval; and \n a rotational skew determining process comprising:\n when determining that the detection distance is identical to the position interval, determining that the skew angle of the document sheet being conveyed by the conveyor is not varying; and \n when determining that the detection distance is not identical to the position interval, determining that the skew angle of the document sheet being conveyed by the conveyor is varying.
