Abstract:
1. A string-striking device of a piano, the string-striking device comprising: a long weight lever, one for every key, which is disposed along a length direction of the key at an upper part of the key on the side opposite to a playing side and which is arranged such that one end of the weight lever is fixed to a piano body so as to allow the weight lever to freely swing up and down, and the other open end, which can be vertically displaced, is brought into contact with the upper surface of the key and applies its own weight on the key; and the string-striking device further comprising a long lifting rail that is disposed between the weight lever and the key, so that the lifting rail extends over a plurality of keys and is fixed to the piano body in such a manner that, by lifting the weight levers, the lifting rail can displace the weight levers from a normal position, where the levers can touch the keys, to a holding position where the levers are spaced from the keys.
