A page turning roller which has two driving rollers and a sensing roller in the same axis can sense the length of page feed, and to set a threshold against the page feed length enables to sense a turn of page for various kind of books. In this study, the turnpage using this roller and the way to sense the failures of turnpage are presented. Influences of diameter difference between sensing roller and driving rollers as well as the condition of operation against turnpage are clarified by experiments.
