Abstract: A lever 40 is supported by a lever supporting portion 41. Through a first pivoting member 52, the lever 40 is urged by a reaction force stabilization spring 54, a first spring 55 and a second spring 56. The downward displacement of a second pivoting member 53 is restricted by a fixed supporting member FR. If the urging force of the first spring 55 exceeds the urging force of the second spring 56, the second pivoting member 53 is displaced upward. A contact member which is in contact with the first pivoting member 52 and the second pivoting member 53 to produce friction force is also provided.

Abstract: A pedal system and method for a musical instrument includes a supporting pedestal operatively connected to a foot pedal such that the foot pedal is pivotal to allow a user to control a musical tone in conformance with the angle of the foot pedal relative to the supporting pedestal. A rotating section is operatively connected to the foot pedal. A pressing member presses upon a contact surface of the rotating section. A leaf spring (or similar bias member) applies pressure on the pressing member causing it to press upon the contact surface of the rotating section. A pressing force adjusting structure to adjust the elastic force with which the leaf spring forces the pressing member upon the contact surface of the rotating section. The rotating section rotates about a central axis of rotation, and the rotating section rotates relative to the supporting pedestal. The rotating section has a contact surface parallel to the central axis of rotation.

Abstract: A damper pedal mechanism, a sostenuto/muffler pedal mechanism and a damper pedal mechanism are incorporated in an acoustic piano for artistic expression, and are independently actuated by a pianist, wherein component parts are assembled into the pedal mechanisms on a base plate, and, thereafter, the pedal mechanism unit is installed in a piano housing so that a factory worker feels the assembling work comfortable.

Abstract: An arrangement for chromatic and diatonic keys for a carillon keyboard is provided. A guide plate has key receiving slots located such that the natural, or diatonic, keys are in a lower row and the accidental, or chromatic, keys are in an upper row, the chromatic keys being placed between the diatonic keys. The pivots for the keys are staggered axially of the keys with the diatonic key pivots being behind the chromatic key pivots. The carillon actuating wires are connected to the keys in a staggered relationship, also, with the diatonic key wires being connected forwardly of the chromatic key wires. This arrangement provides a balance of force for all of the keys.
