  • Patent number: 8779256
    Abstract: A keyboard apparatus capable of enhancing the return capability of hammer assemblies upon key release to improve the capability of repeated key striking and capable of reducing a height size of action units to make the keyboard apparatus compact. The keyboard apparatus includes hammer assemblies each having a butt disposed pivotable about a hammer pivot shaft and a hammer shank extending from the butt. In a non-key-depression state, the hammer shank obliquely extends downward. As viewed from side, a straight line passing though a gravity center position of the hammer assembly and the hammer pivot shaft forms an acute angle less than 45 degrees relative to a horizontal plane in the entirety of a key depression and key release stroke.

  • Patent number: 8648236
    Abstract: A keyboard apparatus wherein a hammer body having movable and stationary engagement portions is configured such that, in its pivotal movement in a forward direction, a click feeling in a key depression touch is generated when the movable engagement portion comes into contact with and gets over the stationary engagement portion, wherein a distance from a hammer pivot shaft to the movable engagement portion at a certain key stroke position in a key depression stroke becomes smaller with an increase in a pressing drive force, and wherein the movable engagement portion comes into contact with the stationary engagement portion in the pivotal movement in the forward direction where a magnitude of the pressing drive force is less than a prescribed value, and the movable engagement portion does not come into contact with the same where the magnitude of the force is equal to or larger than the prescribed value.

  • Patent number: 8558095
    Abstract: A keyboard apparatus capable of being easily designed to have action units whose upper end positions are made low and whose efficiency of drive of whippens is increased. Each of keys of the keyboard apparatus has an upper front part, a bent part extending downward from a rear end of the upper front part, and a lower rear part extending rearward from a lower end of the bent part. An upper surface of a rear end portion of the lower rear part nearly horizontally extends at a height position lower than that of a key fulcrum. Action units are disposed above respective ones of rear end portions of the keys. A driven point of a whippen of each action unit is located at a position lower than the key fulcrum in a non-key-depression state.

  • Patent number: 8541672
    Abstract: A lever is supported by a lever supporting portion. The lever is urged by a first spring and a second spring. The urging force of the first spring varies over the entire operational range of the lever. The second spring and a third spring are provided serially through a movable supporting member. The displacement of the movable supporting member is restricted by a fixed supporting member. If the urging force of the second spring exceeds the urging force of the third spring, the restriction on the displacement of the movable supporting member is removed. Therefore, the present configuration provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.

  • Patent number: 8294009
    Abstract: A surface 60 of a butt 50 has a flat portion 61 which is situated forward and has a small inclination angle and a slanting pressure receiving portion 62 which is situated backward and has a large inclination angle as areas pushed up by a jack 40. Between the flat portion 61 and the slanting pressure receiving portion 62, an escapement portion 63 having an obtuse angle is formed. The escapement portion 63 is provided to correspond to a position of the jack 40 placed immediately after the start of swinging of the jack 40. The inclination angle of the slanting pressure receiving portion 62 is determined such that in a stage where a key starts returning from a slow full stroke key-depression, a position at which the butt 50 is in contact with the jack 40 is maintained with the butt 50 swinging backward.

  • Patent number: 8222509
    Abstract: A pedal device of an electronic keyboard musical instrument comprises a pedal lever swingable according to a depressing manipulation and a reaction force exerting unit for exerting on the pedal lever a reaction force of an amount which depends on an amount of the swing of the pedal lever. The reaction force exerting unit comprises, as an integral unit, a first movable member to be displaced via a thrust rod transferring the swing of the pedal lever, a first urging member which urges the first movable member in a direction to exert the reaction force on the pedal lever, a second movable member to be displaced by the first movable member after the swing of the pedal lever exceeds a predetermined amount, and a second urging member which urges the second movable member in the direction to exert the reaction force on the pedal lever. The first movable member, the second movable member, the first urging member and the second urging member are arranged coaxially around a common axis.

  • Patent number: 8143505
    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.
