Keyboard musical instrument with partially repairable change-over mechanism for changing hammer stopper

摘要

An acoustic piano (1) is equipped with a shank stopper (200) moved into and out of trajectories of hammer assemblies (40) and a change-over mechanism (350) for changing the shank stopper (200), and the change-over mechanism (35) has a pedal (402), a transmitter (350b/300) connected to the pedal and another transmitter (350a) held in contact with the transmitter for transmitting force exerted on the pedal to the shank stopper (200), wherein the transmitters (350a/ 350b) are only restricted in the direction to transmit the force from the pedal to the shank stopper so that the transmitters are independently disassembled and regulable. <IMAGE>
