Abstract
A grand piano has a built-in music rack for keeping a music score book thereon, and the built-in music rack includes a guide laterally extending inside the piano cabinet and a desk board projecting over the piano cabinet and connected to the guide; when a pianist exerts force on the desk board, the guide permits the desk board to slide laterally so that the pianist can easily adjust the music score book to a proper position; since most of the guide is hidden inside the piano cabinet, the pianist feels the grand piano same in external appearance as a standard grand piano.
Claims13
A keyboard musical instrument for generating tones, comprising:
- a cabinet defining an inner space, and having a surface;
- a keyboard having plural keys selectively depressed for designating pitches of said tones to be generated, and placed on said surface so as to expose said plural keys to the outside of said cabinet;
- a tone generating system at least partially housed in said cabinet, and connected to said keyboard for generating tones at said pitches;
- and
- a music rack including
- a desk board against which a document is put and
- a guide having a base embedded in a component member of said cabinet in a direction parallel to said keyboard and a slider partially inserted into said groove and connected to a part of said desk so as to permit a user to move said desk board along said groove through a sliding motion of said slider, thereby being hidden inside said cabinet and connected to said desk board,
- said base having an upper surface rearward inclined and forming another part of said desk board.
