PROBLEM TO BE SOLVED: To provide an electronic keyboard instrument capable of stabilizing, when a second switch is turned ON by a hammer member, the operations of first and second switches without any influence of impact thereof on the first switch.SOLUTION: In the electronic keyboard instrument, a first switch board 11 and a second switch board 12 are independently provided in a keyboard chassis 1 while being separated from each other. The first switch board 1 has a first switch that is turned ON by a key 2 arranged on the keyboard chassis 1 in a manner to be rotatable in a vertical direction upon the depression of the key 2. The second switch board 12 has a second switch 5 that is turned ON by a hammer member 3 that rotates to be displaced in response to the depression of the key 2 and applies action load to the key 2. Accordingly, even if the second switch board 12 receives an impact from the hammer member 3 when the hammer member 3 turns ON the second switch 5, the impact is not easily transmitted to the first switch 4. |
