发明名称 AUTOMATIC BOOKMARK AND PAGE HOLDING DEVICE
摘要 18 AUTOMATIC BOOKMARK AND PAGE HOLDING DEVICE A bookmark and page holding device is provided for automatically holding and marking a page of a book. A spring clip attaches the bookmark to the rear cover of a book. A spring-loaded swing arm is pivotally attached to the spring clip at one end and has a page holder plate pivotally attached to the other end. As the book page is turned, the page holder plate pivots up and away from the page, allowing the page holder plate to return to the next page under the action of the spring-loaded swing arm. In one embodiment, the page holder has an arcuate, inwardly curving edge for engaging the edge of the turned page to facilitate its use with lightweight paper. The page holder plate marks the last page being read when the book is closed as well as when opened.
