Description
かかる発明によれば、操作手段によって非打弦モードが指示されていると、消音機構が駆動されて、ハンマーの動きを弦の直前で規制して前記ハンマーによる前記弦への打撃を阻止する。従って、演奏者は、力の要らない簡単な操作により、ハンマーによる打弦動作を阻止するか行わせるかを切り換えることができる。
図1は、一実施形態であるアップライトピアノ(鍵盤楽器)の構成を示す断面図である。この図において201は鍵盤を構成する鍵である。各鍵201は棚板202上に筬中203を支点として上下方向に揺動自在に支持されている。また、各鍵201毎の後端部の上方にはアクション(打弦機構)210がそれぞれ配設されている。
切り欠き912には、棒状をなすトラップワーク945の一端が係止され、このトラップワーク945が上下することにより、レバー910が軸部901を中心として回動する構成となっている。トラップワーク945の他端はリンク951に係止され、さらにリンク950はトラップワーク955、リンク960、トラップワーク965、ペダル240Aに連結されている。リンク950、960はL字型をなし、それぞれ軸951、961を中心として回動自在に構成されている。
Claims (1)
- 複数の鍵と、
前記各鍵に対応して張設された弦と、
対応関係にある前記弦と前記鍵との間に介装され、鍵が押鍵されるに応じてハンマーが弦を打撃する打弦機構と、
打弦モードまたは非打弦モードへの切り換えを指示する操作手段と、
前記操作手段によって非打弦モードが指示されているとき、前記ハンマーの動きを前記弦の直前で規制し、前記ハンマーによる前記弦への打撃を阻止する消音機構と、
前記ハンマーの動きが前記消音機構によって規制される前において前記ハンマーの動きを非接触状態で検出する検出手段と、
前記検出手段の検出結果に応じて電子音を発生する電子音源と、を具備する
ことを特徴とする鍵盤楽器。
