<P>PROBLEM TO BE SOLVED: To provide a keyboard device of an electronic keyboard instrument, which is capable of sufficiently securing touch weight during key pressing to provide good performance. <P>SOLUTION: The keyboard device includes: a key that extends in a front-to-back direction and freely swings around the approximate center; a hammer 5 that freely turns around a hammer support point 21; and a capstan screw 25 that is provided in one of the key and the hammer 5 and is brought into contact with the other of the key and the hammer 5. The hammer 5 is placed on a rear part of the key via the capstan screw 25, and is pushed up by the key in accordance with pressing of the key, and an angle of the capstan screw 25 relative to a perpendicular direction of the capstan screw 25 is set so that an angle in which the key is in a released state is smaller than an angle in which the key is in a completely pressed state when the capstan screw 25 is viewed from sideways. <P>COPYRIGHT: (C)2013,JPO&INPIT |
