To effectively turn over a page and jump up the page in the case of turning over the pages of a book.

When a book 2 is pressed to a turning-over roller 10 by a book pressing member 13 to turn over a page, the roller 10 is rotated at a low speed to effectively turn over the page in the case of the page 2a of an easily slipping paper quality. When a roller guide 18 is jumped up to separate the page 2a from the roller 10, the roller 10 is rotated at a high speed, thereby jumping up the page 2 with a force above the guide 18 even in the case of the page 2a of paper quality having a weak drape.
