发明名称 Electronic musical instrument with keyboard and cover
摘要 An electronic musical instrument with a keyboard has a musical instrument housing with the keyboard and an operation panel arranged adjacent to the keyboard, and a cover for covering the keyboard and the operation panel. Guide projections are formed at two sides of the keyboard and the operation panel of the musical instrument housing. The cover has first and second cover bodies, a first coupling device for coupling the first and second cover bodies in a foldable manner, and a second coupling device for pivotally coupling a rear end portion of the first cover body with the musical instrument housing. The front end portion of the second cover body is guided and slid along the guide projections when the cover is opened or closed. When the cover is open, the outer surface of the second cover body stands facing forward and serves as a music rack.
