Abstract

The invention provides an auto document feeder (ADF), comprising an ADF body, a grounding component, a cover (11), a sheet metal (48) and two springs (49). The grounding component is disposed on the ADF body. The cover (11) is non-conductive and is capable of being supported on the ADF body in an open / close state. The sheet metal (48) is conducted with the components arranged on the cover (11). The two springs (49) are conductive. The ADF also comprises a conductive elastic component which contacts with the grounding component when the cover is closed, and is fixed to the cover and the conductive components by clamping.
