Abstract: A page-turning apparatus includes a page-lifting reduction device for reducing lifting of each of pages P of a book B at an original position. The page-lifting reduction device includes a page fixing unit to push the pages P at the original position, and an adjusting unit to adjust the position of the page fixing unit in a thickness direction of the book B depending on a thickness of the book B. The page fixing unit includes a page handling portion to handle the pages P in an overlapped state while the pages P are being pushed at the original position. The page-lifting reduction device prevents the pages from being turned in an overlapped state at once.
