Fujitsu Image Scanner ScanSnap SV600
While this portable scanner might not be right for everyone, it’s a superb choice for digitizing books and other large documents. This scanner sits upright and scans documents from overhead so you can position it over a large open book for example. It has a maximum resolution of 600 dpi which is pretty good, and can scan up to 20 pages per minute. This one is definitely designed for use with books, as it includes automatic detection of when pages turn and can scan automatically as you turn the pages in a book. While it works just fine for loose documents, there are some better options if those are the only types of scans you plan on doing. One thing to keep in mind is although this scanner qualifies as a portable model, it’s quite large, weighing more than six pounds and measures about 15 inches long.
