Google Books team open sources their book scanner - attn @hotgiraffe! - http://hackaday.com/2012/11/16/google-books-team-open-sources...
«Unlike some other book scanners, this linear book scanner turns the pages automatically with the help of a vacuum cleaner … after passing them over two image sensors taken from a desktop scanner. The bill of materials comes in at around $1500, but according to the official design documents this includes a very expensive scanner.» ‎- 9000
самое интересное, конечно, это листалка пылесосом. выглядит ненадёжно, но видимо работает хорошо :) ‎- Alex Kapranoff
