This video, titled "BFS-Auto: High Speed Book Scanner at over 250 pages/min," was published by "Ishikawa Group Laboratory."

The BFS-Auto is a high speed scanner that can process 250 pages per minute through "non-destructive scanning" that scans books without breaking them apart.

To scan a book. you simply load it onto the machine.
The scanner will automatically process the rest of the book without you having to turn the pages by hand.

Watching the video, you'll be amazed at how fast it scans.
The books are scanned at high speed and without interruption, so it's possible that some images may be crooked, but even if the image is scanned in a crooked state, it can be readjusted.
