Abstract
A scanning device includes a casing holding a original document table. A facing area is provided to the casing, and a rectangular hole is formed on the facing area. The rectangular hole has edges extending along a main scanning direction and edges extending along a sub-scanning direction. The edges extending along the sub-scanning direction are located in a central area of a photoelectric conversion element row of a sensor assembly in the main scanning direction. The sensor assembly scans the rectangular hole and detects a edge extending along the main scanning direction and a edge extending along the sub-scanning direction, thereby determines a scanning start position.
