ABSTRACT:
An automatic page-turning apparatus for books, magazines and the like comprising a transparent housing having a hinged top to allow a book to be positioned in the housing and seen through the top thereof. Disposed within the housing is a slip-clutch assembly attached to an operating knob located on the exterior of the housing. A monofilament cable is interconnected to the slip-clutch assembly, and is arranged to be operably supported by a plurality of pullies, the cable including a transversely attached page-turning band, which traverses over the pages of the book to engage each succeeding page to be turned. A page-separating wheel is operably synchronized with the movement of the page turning-band to allow the band to engage the page to be turned. When the book is being read, the page-turning band acts as a page hold-down means for one side, while a separate hold-down band is used on the opposite side of the book.
