Abstract
PURPOSE:To easily attain the magnification inspection with high accuracy by counting the number of main scanning lines corresponding to the prescribed distance between lines and inspecting the magnification in the sub-scanning direction of an image scanner in accordance with the result. CONSTITUTION:The titled device is provided with a boundary line setting means 11 to set plural boundary lines of an area with the different reflection factor of a right-angle direction to a sub-scanning direction except an original mounting surface 2' on an original reading platen 1, a boundary line detecting means 12 to detect the set boundary lines by the output of an optical sensor 7 accompanying the sub-scanning direction movement of a carrier 3, a counting means 13 to count the number of main scanning lines corresponding to the prescribed distance between detected boundary lines, and the magnification inspecting means 4 to inspect the magnification to the sub-scanning direction of an image scanner. Namely, based on a prescribed distance, which is already known between the detected boundary lines, and the number of the main scanning lines between the boundary lines counted by a counting means 13, the main scanning line per sub-scanning direction unit length is operated and the magnification inspection in the sub-scanning direction is executed. Thus, the magnification inspection in the sub-scanning direction can be easily executed with high accuracy.
