发明名称 Page holder for books
摘要 A compact page holder device 2 for holding a book 80 open at some selected pages 92, 94. A bundle of book leaves 96 including one of the selected pages 92 extends forward through slot 54, over finger 20, back through slot 52, and under finger 10. A second bundle of book leaves 98 including the other selected page 94 is woven forward through slot 54, over finger 30, back through slot 56, and under finger 40. The interweaving of page holder fingers and book leaf bundles keeps the book and the page holder securely together despite casual handling. Pages may be turned while the page holder is holding the book open by slipping the pages out from under one end finger 10 and back under the other end finger 40.
