Claims

[Claims for Utility Model Registration] (1) A large number of keys are mounted on a keyboard chassis so that they can rotate vertically, and when each key is pressed, the pitch corresponding to the pressed key is emitted. A keyboard device for an electronic keyboard instrument configured to produce a musical tone in response to a sound generation start instruction from a musical sound generation start instruction means, comprising: a key support member that supports each key movably in a longitudinal direction; a biasing member for biasing each key to an initial position in the longitudinal direction; and a biasing member for pressing each key to generate a musical tone of a corresponding pitch in response to a sound generation start instruction from the musical tone generation start instruction means. and then, when the key is moved in the longitudinal direction against the biasing force of the biasing member, the musical tone characteristic control means variably controls the characteristics of the musical tone being generated in accordance with the amount of movement of the key. A keyboard device for an electronic keyboard instrument characterized by: (2) According to claim (1), each of the keys is rotatably supported by an individual key support member installed on the keyboard chassis so as to be slidable in the longitudinal direction of the key. A keyboard device for the electronic keyboard instrument described above. (3) The keyboard device for an electronic keyboard instrument according to claim (1), wherein the musical tone characteristic control means has a sliding volume.
