    • 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.

    • 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. The first movable member and the second movable member are capable of thrusting along the common axis.

    • A lever 40 is supported by a lever supporting portion 41. The lever 40 is urged by a first spring 45 and a second spring 46. The urging force of the first spring 45 varies over the entire operational range of the lever 40. The second spring 46 and a third spring 47 are provided serially through a movable supporting member 48. The displacement of the movable supporting member 48 is restricted by a fixed supporting member FR. If the urging force of the second spring 46 exceeds the urging force of the third spring 47, the restriction on the displacement of the movable supporting member 48 is removed. Therefore, the present invention provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.
    • 杠杆40由杠杆支撑部分41支撑。杠杆40由第一弹簧45和第二弹簧46推动。第一弹簧45的推力在杆40的整个操作范围内变化。第二弹簧 46和第三弹簧47串联地设置通过可动支撑构件48.可动支撑构件48的位移受到固定支撑构件FR的限制。 如果第二弹簧46的作用力超过第三弹簧47的作用力,则可移动支撑构件48的移动限制被去除。 因此,本发明提供一种玩家,其具有与玩家在操纵原声钢琴的减震踏板时感觉到的感觉相似的感觉。
