<P>PROBLEM TO BE SOLVED: To provide an electronic keyboard musical instrument which can be easily moved. <P>SOLUTION: In the electronic musical instrument, a plurality of rotation members 6 for movement are arranged with intervals at lower back side of a musical instrument main body 1 which can be installed on an installment face such as a table and a desk in a playable state. When it is used, as at least a part other than the part where the rotation members for movement are arranged is brought into contact with the installation face, movement on the installation face is suppressed due to contact of the part and installation becomes stable. On the other hand, when the musical instrument main body is lifted up a little at a side opposite to a side where the rotation members for movement are arranged, only the rotation members for movement are brought into contact with the installation face. Thereby, the musical instrument main body is easily displaced with little force, by pressing or drawing it in a direction in which the rotation members can be rotated. Since a plurality of the rotation members for movement are arranged with intervals, the musical instrument main body can be moved in a stable state without becoming unsteady. <P>COPYRIGHT: (C)2009,JPO&INPIT |
