Abstract
A device for detecting a foreign object attached on a surface of a sheet-like medium, comprising a static electricity providing part (A) for providing static electrical charges, a medium transporting part (B) for transporting a medium under detection, and a static electricity sensor and identifier part (C). The medium transporting part comprises a static electricity receiving unit and a static electricity absorbing unit sequentially connected. The static electricity receiving unit is connected to the static electricity providing part (A), and the static electricity absorbing unit is connected to the static electricity sensor and identifier part (C). The static electricity receiving unit is configured to transfer the static electrical charges obtained from the static electricity providing part (A) to the medium under detection. The static electricity absorbing unit is configured to absorb the static electrical charges of the medium under detection.
