SOLUTION: The keyboard device 10 of an electronic piano is provided with an action mechanism 16 similar to the ground piano and a hammer stopper 20 blocking a turning operation of the hammer shank 18. The action mechanism 16 is provided with a wippen 46 and a back check 52, etc., other than the hammer shank 18 and the position relation is almost the same as the position relation in the actual ground piano. The hammer stopper 20 is disposed at a position of blocking the operation when the hammer shank 18 is almost horizontally turned. By such constitution, movements of complicated actions peculiar to the ground piano are simulated and the touch feeling and the repeated hitting property extremely close to the ones of the actual ground piano are obtained.</p> |
