摘要： A keyboard apparatus for an electronic musical instrument includes a key displacement detection unit. The key displacement detection unit includes a first resilient member, a movable member connected to the first resilient member, a second resilient member connected to the movable member, and a base fixing member connected to the second resilient member. The base fixing member may be directly or indirectly fixed to a keyboard musical instrument so that the key displacement detection unit is mounted to the keyboard musical instrument. A first displacement detection sensor is coupled with the first resilient member for detecting a key depression force in a key depression-release direction, and a second displacement detection sensor is coupled with the second resilient member for detecting a key depression force in a key arrangement direction. Both the first displacement detection sensor and the second displacement sensor are mounted on the key displacement detection unit. The first resilient member and the second resilient member are connected to the movable member in a folded manner. As a result, the key displacement detection unit becomes small in size and yet provides a relatively large displacement in the first and the second resilient members with a relatively small key depression force.

摘要： A keyboard apparatus for an electronic musical instrument has a jack which is movable and rotatable by a force to be transmitted from a key, and a hammer which is rotatable by a force to be transmitted from the jack. The jack is rotatably engaged by a fulcrum which is provided in the key. The jack is urged to its original position by a spring. The key has a return load applying portion which abuts the hammer when the hammer rotated by the jack returns to its original position.

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.
