ABSTRACT:
A key striking force sensor suitable for player pianos.
This sensor contains a displacement sensor for measuring displacement between the displacement sensor itself and a catcher which rocks together with a hammer. As the positions of the catchers corresponding to the hammer respectively are almost the same, plural of the displacement sensors can be mounted on a common circuit board. Accordingly, mechanical construction thereof is comparatively simpler than that of conventional player pianos.
