Rails are further provided, and the master music stand and the child music stand are detachably attached in a state of being inserted into the rear and front rails of the plurality of rails, respectively.
[0008]
According to this configuration, a plurality of groove-like rails continuously formed along the left-right direction on the top surface of the top plate are arranged side by side in the front-rear direction. Further, the master 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, the musical score can be sandwiched between the attached parent music stand and the child music stand. Therefore, even a thin score can be set stably without falling down. In addition, since the rail extends in the left-right direction and the master 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 top board, and a musical score can be set. . It is also possible to use two sets of music stand and use them side by side in the left-right direction. In that case, even a large number of music scores can be set in a line-up state, so there is no need to turn pages.
[0009]
The invention according to claim 3 is the music stand of the keyboard musical instrument according to claim 2, wherein the plurality of rails are constituted by three or more rails.
[0010]
According to this configuration, since the groove-shaped rail is composed of three or more, the score can be selected by appropriately selecting the rail to which the master music stand and the child music stand are attached according to the thickness of the score. It can be set well regardless of the thickness.
