Abstract
Abstract The wiring system of this invention is for connecting a number of integrated sound source circuits with the corresponding number of integrated keyer circuits in an electronic musical instrument, and is realized on a single piece of a rectangular wiring substrate. More particularly, the wiring system is characterized in that the sound source circuits are sequentially arranged along one arbitrary side of the rectangular wiring substrate while the keyer circuits are sequentially arranged along the second side of the substrate adjacent to said first side; that conductive members corresponding, in number, to the output terminals of the sound source circuits are extended on one surface of the substrate, from the output terminals toward the side facing said first side; that conductive members corresponding, in number, to the input terminals of the keyer circuits are extended, on the other surface of the substrate, from the input terminals toward the side facing said second side up to the points where the conductive members from the output terminals are terminated on the one side of the substrate; and that at those points the conductive members on both surfaces of the substrate are, respectively, connected by coupling means.
