There appear to be a lot of (overpriced) cameras-on-a-stand, but nothing fully automatic.

The hard part is not capturing an image of each page, but turning them automatically.

Given that planetary scanners are used for rare/fragile/valuable books (for common ones, it's best to just disassemble them and scan the individual leaves), turning the pages automatically at ludicrous speed is exactly what you don't want to do.

Even if books are common they might not be yours and a destructive way of scanning is unacceptable in that case.
