Abstract
A keyboard device is designed for use in an electronic musical instrument. A plurality of keys including white keys and black keys are arranged on a keyboard frame. Supporting parts are mounted on the keyboard frame for supporting the keys pivotably downward and upward. The supporting parts include white key supporting parts to support the white keys and black key supporting parts to support the black keys. The supporting parts are positioned at the rear portions of the keys such that the black key supporting parts are arranged rearward relative to the white key supporting parts. The keyboard frame supports an anti-floating part which extends across the rear portions of the keys and positioned above the supporting parts of the keys so as to prevent the rear portion of the key from floating upward when the front portion of the key is pressed downward.
