<p>PURPOSE:To provide the keyboard musical instrument which can switch from a string nonstriking musical performance wherein no string striking sound is generated without spoiling the key touch to a normal musical performance. CONSTITUTION:The keyboard musical instrument is equipped with hammer head 201 which rotates to strike a string 200, a jack 208 which pushes up the hammer roller 205 to escape it and a regulating button 209 which changes the motion direction of the jack 208 by abutting on a small jack 208B. A hammer stopper 120 can stops the hammer head 201 from striking the string. When the hammer head is stopped from striking the string, a regulating spacer 213 is interposed between the regulating button 209 and small jack 208b. Consequently, the period wherein the regulating button 209 changes the direction of the motion of the jack 208 can be changed.</p> |
