Abstract: According to one embodiment, a booklet page turning apparatus includes a guide member which is provided near a vacuum pad to freely project/retreat from a plane corresponding to the suction surface of the vacuum pad, the guide member moving integrally with the vacuum pad and coming into contact with a page of a booklet at the page turning position to regulate rising of the page.

Abstract: In an apparatus for turning over individual sheets assembled to form a stack, preferably for leafing through program tiles of a jukebox, the sheets are arranged to pivot about mutually parallel pivot pins and are provided with projections rising above the pivot pins on which a support engages so that a sheet is turned over to the opposite side. A space-saving design, in which unintentional turning-over of the pages is effectively prevented, is provided in that at least one fixing device and stop device are provided, the fixing device being in contact with the open sheets so that in the turning-over movement of an open sheet it is moved against a force acting on the fixing apparatus, and the stop device being arranged so that the sheets adjoining the open sheets are in contact with the stop device so that their pivoting in the turning-over direction is prevented at least until the projections of the adjacent sheets are in a position of engagement with the support.
