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.
Claims13
A portable electronic musical instrument divided into two half units which jointly constitutes said instrument, comprising:
- a first unit provided with a keyboard including a plurality of keys;
- and
- a second unit detachable from said first unit and provided with a controlling panel for setting parameters of a tone to be produced and side walls on both sides of said controlling panel;
- said first and second units having such contours that when they are combined for portage they form a box like structure;
- said first unit comprising a front wall and two side walls, the upper edge of each side wall decreasing its height toward said front wall so as not to interfere with a hand of a performer playing said musical instrument.
A portable electronic musical instrument comprising a lower unit including a plurality of keys, an upper unit including a controlling panel and vertically mounted on said lower unit to provide a performable state, a blind board, and keyboard clamping means provided for one surface of said blind board, said upper unit being horizontally mounted on said lower unit and said blind board being disposed to close a space defined by a front surface of said lower unit and a bottom surface of said upper unit thereby forming a portable box like structure with said lower unit, said upper unit and said blind board, said keyboard clamping member engaging said key for preventing tilting thereof.
A portable electronic musical instrument comprising a lower unit provided with a plurality of juxtaposed keys, an upper unit including a controlling panel and vertically mounted on said lower unit to provide a performable state, and a plurality of fittings secured to outer surfaces of said upper and lower units, at least one of said fittings being used in common when said upper unit is vertically mounted on said lower unit and when said upper unit is horizontally mounted on said lower unit to form a portable box like structure.
