Description
ジャック小２０Ｂとレギュレチングアッセンブリ４０との距離Ｄは、レギュレチングボタン４０Ｂを調整することにより可変され、この距離Ｄを調整することにより接近ｄ（＝鍵盤を非常に低速度で押し下げてハンマー３１を回動させたときの弦１に最接近するハンマー３１と弦１との最小距離）が調整される。すなわち、接近ｄを大きくする場合は、距離Ｄを小さくしてジャック２０がバット２６から脱進を開始する時期を早め、接近ｄを小さくする場合は、距離Ｄを大きくしてジャック２０がバット２６から脱進を開始する時期を遅くする。なお、接近ｄは通常２〜３ｍｍ程度に調整されている。
Jack distance D between the small 20B and regulating quenching assembly 40 is variable by adjusting the regulating quenching button 40B, hammer 31 closer d (= keyboard to adjust the distance D depress at very low speed The minimum distance between the hammer 31 and the string 1 closest to the string 1 when rotating the) is adjusted. That is, in the case of increasing the approach d, the distance D is decreased to accelerate the time when the jack 20 starts to evacuate the butt 26, and in the case of decreasing the approach d, the distance D is increased to make the jack 20 a bat 26. Slow down the time to start escaping from. The approach d is usually adjusted to about 2 to 3 mm.
