<p>PURPOSE:To provide the keyboard musical instrument on which a string non- stroke musical performance and a normal musical performance can be switched without spoiling key touches by moving a shelf plate so that an action is put away from strings. CONSTITUTION:This keyboard musical instrument is equipped with tensed strings 200, the action 400 including a hammer 300 which rotates clockwise in the figure to strike the strings 200 and a keyboard 500, the 2nd shelf plate 701 which supports the action 400, a 1st shelf plate 703 fixed to the musical instrument, a shank stopper 120 which stops the hammer 300 from striking the strings, and a cam shaft 700 which moves the 2nd shelf plate 701 toward the 1st shelf plate 703 when the strings are struck.</p> |
