ABSTRACT:
A page turner capable of turning the pages of a book forwards or backwards which includes a roller mounted on a mounting above a book support. The mounting is movable relative to the support so that the roller can engage pages on either side of a book spline. The roller is rotatable in opposed senses and is operable so as to displace a page to be turned under the roller to release the page and a flap carried on the mounting alongside the roller is movable relative to the support to move the released page to the opposite side of the book spline.
