Abstract
An image scanning system of the present invention uses an image capturing unit moving unidirectionally along an optical axis direction, such that an object is positioned within a range of the depth of field of the image capturing unit. The optical axis direction is perpendicular to a plane, and a platform bearing the object and the plane form an included angle, such that multiple inclined surfaces of the object face the same end of a scanning direction, or such that one of the multiple inclined surfaces is parallel to the plane and other inclined surfaces face the same end of the scanning direction, wherein the scanning direction is parallel to the plane. Therefore, in the process of one-time scan, the scanning height of the image capturing unit only rises unidirectionally or descends unidirectionally and has no turning point, and thus, no backlash problem will happen.
