PATENT SO3160 AUTOMATIC PAGE-TURNING DEVICE ABSTRACT OF THE DISCLOSURE An automatic page-turning device for turning pages of a book or the like as placed in an opened condition to expose a first page to be turned at one side of a spine and a second page in a stack of turned pages at the opposite side of the spine, comprises a carrier drum having a perforated peripheral wall and being bodily movable from a first position opposing an outer edge portion of the first page of the opened book to a second position in which the carrier drum opposes an outer edge portion of the second page, a suction device by which a vacuum is applied to the interior of the carrier in its first position for causing adherence of the first page thereto and the transport of the first page with the carrier drum toward the second position, with the first page being isolated from the effect of the vacuum at a position of the carrier drum intermediate its first and second positions for releasing the first page from the carrier drum and permitting the reception of such released first page by a page guiding member movable with the carrier drum and carrying the released first page at least until the carrier drum passes the spine of the book or the like, and a reverting roller in parallel, side-by-side relationship with the carrier drum and being movable therewith for withdrawing the first page from the page guiding member and stacking the same against the second page during final movement of the carrier drum to its second position. The automatic page-turning device is desirably SO3160 applied to an optical reader system in which an optical reading element, such as, a CCD line sensor, is movable with the carrier drum in the course of the movement of the latter between its first and second positions for reading information on the exposed pages. -2-
