It's genuinely surprising that the Advanced Vertical Scanner is the only one of its type that I've come across. Its sort solves the problem of splayed pages that don't copy properly so that more printed media can be effectively rendered digitally.
Where the conventional scanner is composed of a single flat reading bed, Sang Hyun Jeong and Allan Hyunwoo Kim conceived their slim invention with in an upright position with a pair of windows on opposite faces. The rigidity of the device allows you to spread heavy hardcover books over top.
This setup leaves the pages flatter so that the words and photos near the novel's binding aren't fuzzy and discolored. The Advanced Vertical Scanner copies right up to its slender upper edge and can easily read single-sheet documents on either side.
