ABSTRACT:
A document scanning device is provided that is able to accurately and easily scan paper fingerprint information, even if particulate rubbish such as paper powder or dust is adhering to the surface of a document platen glass. In an image scanning device able to scan using both a stationary document scanning method as well as document feed scanning method, paper fingerprint information is scanned using either of the above methods. Subsequently, a conveying unit and a scanning unit are moved so as to re-scan the paper fingerprint information in the same fingerprint acquisition region. The above operation is repeated until both sets of paper fingerprint information are coincident.
