  • Key-pad operating mechanism of saxophone
    Patent number: 5990398
    Abstract: A key-pad operating mechanism of the saxophone for forcibly separating a normally closed key-pad from the tone hole seat via an arm using the leverage principle by pressing the operating lever for the normally closed key-pad even if the normally closed key-pad is stuck to the tone hole seat. The mechanism can easily open the normally closed key-pad without affecting any traditional maneuverability of the instrument and prevents key-pads from becoming inoperable during a play.
