<P>PROBLEM TO BE SOLVED: To provide a music stand device that has a music score plate arranged to be flush with a top plate when the music score plate is in a fallen state, and can increase the positional accuracy of the arrangement position of the music score plate with respect to the top plate. <P>SOLUTION: A housing member 51 and a guiding member 52 are attached on the lower surface of a top plate 20. Therefore, when the other end of a supporting member 40 is rotatably connected to a bottom surface 51a1 of the housing member 51, the other end of the supporting member 40 is arranged in a position lower than the lower surface of the top plate 20. As a rectangular main-body side guiding groove 22 is recessedly provided on the lower surface of the top plate 20 and a guide side guiding groove 52b is recessedly provided on the guiding member 52, the main-body side guiding groove 22 and the guide side guiding groove 52b are arranged in positions lower than the upper surface of the top plate 20. Therefore, when a music score plate 30 is fallen down as a shaft-shaped member 31 slides along the main-body side guiding groove 22 and the guide side guiding groove 52b, the music score plate 30 is arranged in an opening 21 of the top plate 20 so as to be flush with the top plate 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
