Saxophone key pad mechanism

摘要

The mechanism to operate the key pad of a musical instrument, and especially a saxophone, has a lever which moves up and down, to be operated for the normally closed key pad. An operating lever is next to the normally closed key pad, to move the normally open key pad up and down, and this operating lever is supported by an arm with a support point. The arm of the normally closed key pad, to close the sound opening, opens using the support point as the pivot when the operating lever for the normally closed key pad is pressed.
