摘要： A keyboard musical instrument such as a grand piano has a front top board and a rear top board with which an upper opening of a piano case is closed, and the rear top board is confronted with the front top board at the closing position; an automatic board spacer is provided between the front top board and the piano case, and automatically increases the gap after the rear top board leaves the closing position and decreases the gap at the arrival of the rear top board at the closing position, thereby preventing the user's fingers from pinch between the front and rear top boards.

摘要： A top board structure is adapted to a keyboard instrument (e.g., a grand piano) having a pair of a top board rear and a top board front, which are arranged close to each other with a gap therebetween above the upper portion of a case. Herein, the gap is enlarged using sliders along which the top board front can be moved forwards and backwards as necessary, wherein the top board rear is allowed to be opened only when the top board front is positioned to enlarge the gap. Therefore, the user can easily hold the free end of the top board rear to be opened or closed with fingers. Thus, it is possible to prevent the player from being anxious that finger tips will be caught in the gap during an opening motion and/or a closing motion of the top board rear.
