The musical score can be seen through the watermark through only one sub-stand. Therefore, the background of the portion around the score is not transparent, and the score is clearly visible, so that the performer can concentrate on viewing the score.

According to a second aspect of the present invention, in the music stand of the keyboard instrument according to the first aspect, the groove shape is formed continuously on the upper surface of the top plate along the left-right direction and arranged side by side in the front-back direction. Is further provided, and the parent music stand and the child music stand are detachably attached to the rear and front rails of the plurality of rails, respectively.

According to this structure, a plurality of groove-shaped rails formed continuously on the upper surface of the top plate along the left-right direction are arranged side by side in the front-back direction. Further, the parent music stand and the child music stand are detachably attached in a state of being inserted into the rear rail and the front rail. From this, it is possible to sandwich the musical score between the attached parent music stand and child music stand. Therefore, even a thin sheet of music can be set stably without falling down. Also, since the rail extends in the left-right direction and the parent music stand and the child music stand are detachably attached to the rail, the music stand can be attached to any position in the left-right direction of the tabletop to set the score. . It is also possible to use two sets of music stands arranged side by side in the left-right direction. In this case, even a large number of music sheets can be set in a lined state, so that turning over is unnecessary.

The invention according to claim 3 is the music stand of the keyboard instrument according to claim 2, characterized in that the plurality of rails are composed of three or more rails.

According to this construction, since the groove-shaped rail is composed of three or more rails, by appropriately selecting the rails to which the main music stand and the sub-music stand are attached according to the thickness of the musical score, The score can be set well regardless of its thickness.
