ABSTRACT:
A portable electronic musical instrument is composed of two separable units, that is an upper unit including a controlling panel and a lower unit including a keyboard. For performance, the upper unit is vertically mounted on the lower unit and for portage the upper unit is horizontally mounted on the lower unit to form a portable box like structure. Both side boards of the lower unit are inclined toward the front surface of the keyboard so as not to interfere with performers hands in playing. Base portions of side boards of the upper unit are also inclined towards the keyboard so as to stabilize the upper unit in the performable state.
