ける鍵タッチの重さは演奏者にとってタッチ感に微妙な
差異を感じさせ、心理的に更には演奏内容に大きな影響
を与えるため、この鍵タッチの重さを全ての鍵盤に対し
て一様に揃えることが要求されている。Pianos, known as keyed musical instruments, operate an action mechanism that is linked to the keyboard by pressing the keys, and when the strings are struck, the vibration energy is propagated and diffused to the soundboard body, and is radiated as piano sound. The weight of the key touch during performance makes the performer feel a subtle difference in touch feel, and psychologically, it has a big impact on the content of the performance, so this weight of key touch is applied to all keys. They are required to be uniform.
この鍵タッチの重さは原則的には各演奏者の好みに合せ
て整調されるものであるが、実際には製作時において標
準の重さに設定される。In principle, the weight of this key touch is adjusted according to each performer's preference, but in reality it is set to a standard weight at the time of manufacture.
すなわち、この整調方法としては、第1図に示すように
、鍵盤1の適宜位置に直径10rrrln程度の貫通孔
2を1個又は数個側面方向に穿設し、この貫通孔2に鉛
3を圧入埋設し、鍵盤1の板後部1aの重量を加減して
いる。That is, as shown in FIG. 1, this adjustment method involves drilling one or more through holes 2 with a diameter of about 10 rrrln in the side direction at appropriate positions on the keyboard 1, and filling the through holes 2 with lead 3. The weight of the rear plate 1a of the keyboard 1 is adjusted by press-fitting the plate.
しかし、例えば音楽学校、ピアノ教室などで使用される
練習生用のピアノとしては、指の訓練が要求されること
から、鍵盤の鍵タッチ感が通常のピアノのそれよりも幾
分重く設定されたものが場合に応じて必要となる。However, since pianos for trainees used in music schools, piano classes, etc. require finger training, the touch feel of the keys has been set to be somewhat heavier than that of a regular piano. Things are needed depending on the situation.
しかし、上記した通り、ピアノの鍵タッチ感は製作時に
一旦所定の重さに整調されると鉛3を交換したり新たに
付力叱たりしないかぎり変えることが困難であるため、
鍵タッチ感の異なった2台以上のピアノを準備する必要
があった。However, as mentioned above, once the piano's key touch feel is adjusted to a predetermined weight during manufacture, it is difficult to change it unless the lead 3 is replaced or a new force is applied.
It was necessary to prepare two or more pianos with different key touches.
従って、この考案は上記のような不便、不都合を解消す
