Abstract
An electronic keyboard musical instrument comprises a keyboard assembly including juxtaposed keys and juxtaposed swing weight mechanisms, each of the keys correspondingly linked with each of the swing weight mechanisms. Actuating members are provided corresponding to the respective swing weight mechanisms each of which in turn actuates each corresponding key. The actuating members are arranged in the vicinity of the fulcrum of the swing weight mechanisms and disposed in two rows as a front row and a rear row and extending downward through the key bed. The heights of the actuating members are made small. An actuator cover has a rearward descending slant wall so that the knees of the player will not be obstructed in depressing the pedals.
