When, in a state in which a browsing screen 40 of an electronic book is displayed on a touch panel display unit 20, a touch position detecting circuit 21 detects that an indicating object F performed a displacement indicating the folding over of a corner, a bookmark registration unit 11 changes the corner to a folded-over display 61 and registers the displayed page as a bookmark. When, in a state in which a page registered as a bookmark is displayed on the browsing screen 40, a touch position detecting circuit 21 detects that the indicating object F performed a displacement indicating a page-jump, a bookmark-jump unit 12 switches the currently displayed page to another page registered as a bookmark. |
