ATIZ has developed an automatic book scanner that is of a somewhat-reasonable size. There are a couple other automatic book scanners out there but they are huge machines according to Art Sarasin, president of ATIZ. This machine uses a page-turning mechanism. It connects via USB 2.0 and all you do is designate how many pages you want to scan and it does the rest of the work. If you want the ease of this, you will have to pay for it. They are currently taking a preorders and it will be available next month for a hefty $35,000.
