ABSTRACT:
A portable image scanner capable of selecting a manual document loading mode in which a cover member is united to a scanner body to feed a cut-sheet document through a document passage defined between the united scanner body and cover member for scanning the document, or a self-propelling mode in which the cover member is separated from the scanner body to move the independent scanner body on a thick document such as a book. The scanner body has a document sensor for detecting the cut-sheet document placed in the document passage in the manual document loading mode, and the thick document in the self-propelling mode to prevent the scanner body moving on the document from falling out of the edge of the thick document.
