发明名称 Key apparatus for electronic musical instrument
摘要 A key apparatus is provided in which the resistance of the keys to being depressed is such that the touch feeling of a real piano key is simulated. A key is pivotally mounted so that rotation is performed in response to depression. A weighted lever and a weight embedded in the key serve to urge the key in the opposite rotational direction. A deformable element is arranged so that it contacts the key after the key has been depressed a predetermined distance. The resistance of the deformable element to being deformed initially increases as the key is depressed beyond the predetermined distance, and then decreases as the key is depressed further.
