<p>A keyboard includes plural keybar actuatros (11) each including plural keys (19, 23, 27, 31) hingedly interconnected (25, 29, 33) and a sensing device (13). The keys of a keybar actuator are all actuated by a common finger (45) in touch typing and therefore are nto jointly actuated. Depression of one key causes the keybar actuator (11) to pivot and the sensing device (13) indicates which key is depressed depending upon the amount of keybar actuator rotation. Alternate sensing devices include individual contact switches associated with each key.</p> |
