<P>PROBLEM TO BE SOLVED: To provide an electronic keyboard musical instrument equipped with a leg part in which a power source can be housed. <P>SOLUTION: At least one of a plurality of leg parts supporting a primary musical instrument body part at a prescribed height is formed in a shape having mutually opposite surfaces. When the one leg part is formed in the shape having the mutually opposite surfaces, a space part having a prescribed width is formed between the two opposite surfaces, so the power source which supplies electric power to the primary musical instrument body part is stored in the space part. Thus, the electronic keyboard musical instrument has a keyboard having pluralities of white keys and black keys and the power source which supplies the electric power needed to electrically output prescribed signals by keys according to key pressing operations of the respective keys to the primary musical instrument body part is built in the leg part distant from the primary musical instrument body part. Consequently, it is made possible not only to easily replace the power source, but also to prevent other components arranged in the primary musical instrument body part from adversely being influenced to malfunction or get out order, and a layout etc., of respective components in the primary musical instrument body part can suitably be designed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
