发明名称 Multi-page viewing binder
摘要 An improved music holder ( 12 ) enabling the user to view more than two sheets of music (or other printed material) at a given time. A front cover ( 14 ), a back cover ( 16 ), a plurality of display boards-A ( 24 ) and a plurality of display boards-B ( 28 ) are bound together with a wire spiral ( 18 ). Light-weight chain ( 20 ) (or similar non-stretching material) attaches to chain anchors ( 32 ) to support the front cover ( 14 ) in an open position. Paper clamp tabs ( 26 ) affix paper clamps ( 22 ) to the top edge of each display board ( 24 )( 28 ). Music sheets are inserted by sliding the top or bottom edge of each sheet between the display board ( 24 )( 28 ) and the paper clamp ( 22 ). Display boards ( 24 )( 28 ) may be turned in either direction to access another set of music sheets. Hanging brackets ( 30 ) secure the music holder ( 12 ) to a standard music stand (or similar device).
