PIANO TOUCH TYPE MECHANISM BUTTON DEVICE

摘要

PURPOSE:To provide the piano touch type mechanism button device which can simultaneously cancel the impact noise at the time of resetting of a mechanism button and the resonance of the mechanism button. CONSTITUTION:This mechanism button device has the mechanism button 1 which has a mechanism operating rod 14 actuating a mechanism 12 at its moving end and is freely turnably provided in a cabinet 11, an elastic piece A which energizes this mechanism button 1 in a resetting direction at all times and an elastic piece B which comes into contact with the mechanism button 1 when the button is reset. The impact force at the time of resetting of the mechanism button 1 is absorbed by the elastic piece B.
