)項記載の電子鍵盤楽器の鍵盤装置。[Claims for Utility Model Registration] (1) A keyboard chassis, a key rotatably mounted on the keyboard chassis in the vertical direction, and a seesaw rotatably mounted below the key on the keyboard chassis. a spring member having a predetermined spring force and having one end attached in a free state below the action arm on the keyboard chassis; a pressing protrusion that presses one end; and a pressing protrusion that is interposed between the other end of the action arm and the free end of the spring member to apply a predetermined magnetic force to the other end of the action arm and the free end of the spring member. and a stopper provided on the keyboard chassis to prevent elastic displacement of the free end of the spring member beyond a predetermined value, when the key is pressed downward, The action arm, whose one end is pressed by the pressing protrusion, rotates and elastically displaces the free end of the spring member, which is adsorbed and coupled to the other end by the magnetic force coupling means, so that the key is depressed until it reaches a predetermined position. Then, the free end of the spring member, which continues to be elastically displaced by the rotation of the action arm, is prevented from continuing its elastic displacement by the stopper, and this blocking force prevents the actuation by the magnetic coupling means. The adsorption connection between the other end of the action arm and the free end of the spring member is released, and the free end of the spring member, which is prevented from continuing its elastic displacement, separates from the other end of the action arm, which continues to rotate, and returns elastically. and the free end of the returned spring member is configured to be adsorbed and coupled to the other end of the action arm again by the magnetic force coupling means when the action arm is returned by releasing the key 2. A keyboard device for an electronic keyboard instrument characterized by: (2) Claim No. (1) characterized in that a weight portion is provided at the other end of the action arm.
) A keyboard device for an electronic keyboard instrument as described in item ).
