<P>PROBLEM TO BE SOLVED: To improve the durability and assembly and to obtain a key touch feeling close to a key touch feeling of an acoustic piano. <P>SOLUTION: In a keyboard apparatus in which a keyboard chassis 1 where keys 2 are arrayed is provided with hammer arms 3 imparting action loads to each of the keys 2, each key 2 is provided with an extension part 36 which extends to project downward from the key, and a hammer holding part 38 comprising an upper fixed plate part 40 for holding a key abutting part 29 of the hammer arm 3 and an elastically deformable lock part 41 is provided below the extension part 36. The upper fixed plate part 30 does not elastically deform, therefore, the durability is high and even when the key 2 is strongly pressed, the keying operation is securely transmitted to the hammer arm 3, thereby obtaining a key touch feeling close to the key touch of an acoustic piano. Further, the hammer holding part 38 projects downward from the key 2, so that the hammer holding part 38 is easy to see, the key abutting part 29 is easily held by the hammer holding part 38, and the assembly operability is improved. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
