<p>A keyboard apparatus of an electronic musical instrument includes keys (K), mass members (H, W), and springs (S1, S2). Each key (K) can pivot about a first pivot fulcrum (P2). Each mass member (H, W) can pivot about a second pivot fulcrum (P1). Each spring (S1, S2) supplies a biasing force to at least the corresponding mass member (H, W) so that the mass member returns to an initial state. In this apparatus, each key (K) has a point of application (T) for pivoting the corresponding mass member (H) in the same direction as a pivoting direction of each key (K) when each key is depressed.</p> |
