IPC: G10B3/12
Filed: 1991-12-20
Abstract: PURPOSE:To provide a keyboard device having simple constitution which gives a player a key touch similar to the key touch of an acoustic piano. CONSTITUTION:When the tip part of a key 1 is depressed the key 1 rotates clockwise around a rotational fulcrum part 2 as a center of rotation, but the lower part of a rotary body 7 provided on a lower position of the key 1 abuts on the pressed part 15 of a hammer arm 3 fitted rotatably on a keyboard chassis 6, so a key load is placed on the key 1 by the weight of the hammer arm 3. When, however, the key 1 is further depressed, the rotary body 7 leaves the depressed part 15 of the hammer arm 3, so the key load is eliminated at the moment. Consequently, the player receives the feeling of key releasing, i.e. the falling feeling of the key 1.
