Action for electronic piano |
摘要 |
A piano action is provided for an electronic piano. Tones are generated electronically, but the action retains the feel of a conventional piano action without the necessity of a hammer or hammer-like member. The piano key is provided with a rounded, convex shoulder which presses against a rounded, convex surface on a lever. The two convex surfaces are configured and positioned so that one slides over the other to provide the feel of let-off of a conventional piano action. The lever is spring-biased by means of two different springs to rest position, and acts to move a spring wire contact from a first bus to a second bus.
