Abstract
Abstract The invention is a multipurpose device made of a clear transparent material which blends in with any decor. Its unique appearance makes it inconspicuous and allows for an unobstructed view when not in use. It is collapsible, portable and can be used as a copyholder, lectern or book support capable of holding books and copies of various size and nature such as dictionaries, bibles, notebooks, mechanical drawings, musical compositions, office dictation and the like. The device consists of a back support member with a clip mounted at the top front of the same, a ledge mounted near the bottom front of said back support member, two rails which parallel each other mounted in a vertical position on the back of said support member and two quadrilateral legs which slide into said rails in six different ways to form different adjustable positions, the lectern being one of said positions.
