Claims

[Scope of Claim for Utility Model Registration] An elastic flexible circuit board arranged above the net and having a plurality of fixed contacts arranged side by side in the width direction of the neck on the upper side, and a plurality of movable contacts arranged side by side in the width direction of the neck on the lower side. In a musical tone designation signal input device for an electronic stringed instrument, the board is arranged such that each of the fixed contacts and each of the movable contacts face each other at a predetermined interval, on the elastic flexible board that corresponds to the plurality of movable contacts. A bulge is formed on the upper surface of the elastic flexible plate to ensure that each of the movable contacts comes into contact with each of the fixed contacts when each position is pressed simultaneously. A musical tone designation signal input device for electronic stringed instruments.
