Abstract: In order to prevent a page from returning from a page-turning end point to a page-turning start point and improve the reliability of page turning, in addition to a catching section having a plurality of vane sections provided on the outer circumferential surface, there are provided a pull-in roller which rotates around the rotation axis of the catching section and has a diameter smaller than that of the catching section and a pressing roller having a diameter smaller than that of the pull-in roller. When a page is conveyed by a sticking section, the catching section brings the page to a page-turning end point while rubbing the page surface with the rotating vane sections, and the pull-in roller pulls in the page caught by the vane sections of the catching section. The pressing roller presses the page pulled in by the pull-in roller at the page-turning end point.

Abstract: When a page is conveyed from a sticking section, a catching section catches and brings the page to a page-turning end point by a vane section rubbing against a surface of the page. A regulation section is provided extending from a side of a roller cover to an area below vane sections, and regulates the movement of each vane section before a vane section strikes the page already fixed at the page-turning endpoint or strikes a holding plate. By being formed of an elastic member, each vane section is pulled into the roller cover while being greatly bent by the regulation section.
