Abstract
A scanning device comprises a scanner body including a frame, a cover pivotably mounted to the scanner body so that it can be opened and closed, a scan unit mounted to the scanner body to scan an image of a document, and a grounding unit for grounding a noise radiated from the scan unit to the frame and thereby remove the noise. The grounding unit is selectively connected to the frame according to whether the cover is opened or closed. The connection distance between the grounding member and the frame is reduced as much as possible to prevent induction of radiated EMI by the grounding member, and to achieve effective grounding of the radiated EMI.
