摘要： 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.

摘要： 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.

摘要： A keyboard instrument such as an electronic piano comprises a keyboard structure that is basically identical to the keyboard structure of an upright piano except hammer assemblies and a struck portion attached to an action bracket. Each of the hammer assemblies is constituted by a hammer shank and a pseudo hammer, one of which is used to strike the struck portion having a multilayer structure including an elastic member (e.g., a plate spring) sandwiched between buffer materials. The elastic member has a prescribed number of striking areas in correspondence with keys arranged on a keybed, wherein the striking areas are gradually increased in weights and bends (or deflections) in a pitch descending order from higher pitches to lower pitches. Thus, it is possible to simulate weight factors and bends (or deflections) of strings actually struck by hammer felts in an upright piano.
摘要翻译：诸如电子钢琴的键盘乐器包括键盘结构，其基本上与直立钢琴的键盘结构相同，除了锤子组件和附接到动作支架的敲击部分。每个锤组件由锤柄和假锤构成，其中一个用于击打具有夹在缓冲材料之间的弹性构件（例如板簧）的多层结构的击打部分。弹性构件具有与布置在键盘上的键相对应的规定数量的打击区域，其中击打区域以从较高间距到较低间距的间距降序逐渐增加重量和弯曲（或偏转）。因此，可以模仿在直立钢琴中实际上被锤子毡击中的弦的重量因子和弯曲（或偏转）。

摘要： An action for a keyboard-based musical instrument is provided for preventing action parts made of a synthetic resin from being charged to eliminate stains due to dust and motes in the air attracted by static electricity. The action is composed of a plurality of action parts coupled to one another, including a hammer. The action actuates in response to depression on a key to swing the hammer which strikes a string. At least one of the plurality of action parts is made of a synthetic resin which has electrical conductivity at least on a surface thereof.

摘要： To provide an electronic piano maintaining a compact appearance and providing the key touch equivalent to that of an acoustic piano. A hammer equivalent member is composed of a butt, a L-shaped member and a catcher shank. When the butt is pushed up by a jack responsive to the key depression, the hammer equivalent member starts rotating in a direction reverse to the rotary direction of a depressed key. Subsequently, after the jack leaves the butt, the hammer equivalent member continues to be rotated inertially. By contacting the projection of the L-shaped member of the hammer equivalent member, a stopper stops the inertial movement of the hammer equivalent member. The hammer equivalent member is almost equivalent to the hammer assembly of the usual acoustic piano in inertial moment and the angle formed by the center of gravity relative to a virtual perpendicular passing a center pin. Furthermore, the hammer equivalent member is shorter than the hammer assembly in appearance.

摘要： A keyboard apparatus has a support member and a plurality of white keys and black keys. Each of the white keys and the black keys has a fulcrum section and a driving section, and are pivotally mounted about the fulcrum section with respect to the support member. A mass body assembly, that is an action member, has a moving fulcrum, a driven section on a first side of the moving fulcrum that is driven by each of the driving sections of the white keys and the black keys, and a center of gravity that is located on a second side opposite the driven section with respect to the moving fulcrum. The distance between the driven section and the moving fulcrum of the mass body assembly for the black key is greater than the corresponding distance for the white key. The mass body assembly on the second side is formed from the same members that are commonly used for both the white keys and the black keys.
