<P>PROBLEM TO BE SOLVED: To provide a music score rack system of a keyboard instrument which can be reduced in its manufacturing cost and can be relatively easily fabricated. <P>SOLUTION: The music score rack system of the keyboard instrument has a fallboard front section 11 and fallboard back section 12 which are freely rotationally movably coupled to each other and cooperatively open and close a playing section 2 of an organ body 3. The fallboard front section 11 is freely rotationally movably attached to the body 3 and is so formed as to be opened in an upright state by rotationally moving backward and the fallboard back section 12 is so formed as to be opened by moving backward while rotationally moving relative to the fallboard front section 11 as the fallboard front section 11 rotationally moves backward. The music score rack system is provided with a music score rest 11 for resting music score F against the same, and a music score prop 9b which is formed between the playing section 2 of the organ body 2 and the opened fallboard front section 11 and is used to be placed on with the music score F. <P>COPYRIGHT: (C)2004,JPO |
