摘要： A piano selectively playable in normal and soft modes has multiple piano keys and actions, including a wippen assembly, and multiple piano hammers. A soft mode pedal system includes soft and ultra-soft mode pedals, and a hammer rest rail mounted for movement between normal and soft mode positions. A piano key lift rail is mounted for movement between a normal mode position spaced from lifting contact with the keys and a soft mode position in contact with and lifting the keys and the wippen assemblies. A soft mode pedal linkage assembly between the soft and ultra-soft mode pedals and the hammer rest and piano key lift rails causes movement of the hammer rest rail, piano hammers, the piano keys, and the wippen assemblies upon actuation of the soft mode pedal between normal mode position and soft and ultra-soft mode positions.

摘要： An action for a piano is provided for clarifying a timing of let-off, improving the sequential touching capabilities, and consequently realizing high playing performance excellent in expressive power in a simple structure without adversely affecting the key touch feeling. The action for a piano swings a hammer in response to a touch on a key, and comprises a wippen pushed up by the key to pivotally move, a regulating button having a flat jack contact surface on the lower end, and a jack having a flat regulating button contact surface which comes into contact with the jack contact surface as the key is depressed. The jack comprises a molding made of a thermoplastic resin containing long fibers for reinforcement.

摘要： An upright keyboard instrument comprises a prescribed number of keys that are interlocked with actions, hammer assemblies, and a plate spring unit, which is interlocked with a loud pedal. When the key is depressed, the action is activated to drive the hammer assembly, thus producing a musical tone. Each of plate springs is normally arranged close to an end portion of a whippen included in the action. Upon depression of the key, the end portion of the whippen comes in contact with the plate spring to cause a resistive force, which is transmitted back to a player's finger depressing the key. When the loud pedal is depressed, the plate spring departs from the end portion of the whippen, which becomes free to rotate upon depression of the key, thus realizing loudness effect on sound.
摘要翻译：直立键盘乐器包括与动作联动的规定数量的琴键，琴槌组件和与大踏板互锁的板簧单元。当按下键时，动作被激活以驱动琴槌组件，从而产生音调。每个板簧通常布置成靠近动作中包括的搅动器的端部。在按下钥匙的情况下，触片的端部与板簧接触以产生阻力，该阻力被传回给玩家的手指压下钥匙。当踏板踩下时，板簧从起搏器的端部离开，当钥匙按压时，该弹簧自由旋转，从而实现对声音的响度。

摘要： A keyboard for an electronic instrument and an electronic piano providing a key touch and a key touch response similar to those of an acoustic piano and stabilizing the key touch response for each key. Two detection positions of a key stroke are detected by a jack tail sensor or a jack sensor by detecting contact of a jack tail equivalent member or a jack equivalent member, before or after a hammer equivalent member disengages from or releases from a jack equivalent member. A time difference between the two positions is not adversely affected by the let-off of the jack equivalent member. Therefore, the positions and the time difference are detected stably for each key. Sound timing and sound intensity are controlled based upon the detected positions and time difference between the positions. Therefore, a key touch response, similar to that of an acoustic piano, can be stably obtained for each key.
摘要翻译：用于电子乐器的键盘和电子钢琴，提供与声学钢琴类似的按键触摸和按键触摸响应，并稳定每个键的按键触摸响应。钥匙行程的两个检测位置由千斤顶尾部传感器或千斤顶传感器通过在锤子等效构件脱离或从千斤顶当量构件释放之前或之后检测千斤顶等效构件或千斤顶当量构件的接触来检测。两个位置之间的时间差不会受到千斤顶等效构件的释放的不利影响。因此，针对每个键稳定地检测位置和时差。基于检测到的位置和位置之间的时间差来控制声音定时和声音强度。因此，可以稳定地获得与每个键相似的与原声钢琴相关的按键触摸响应。

摘要： The subject action is a modification of the traditional upright action. The traditional jack spring is eliminated. Its function is assumed by a jack/repetition spring, which is a compression spring adjustably mounted between the jack near the end that engages the hammer butt and a pilot attached to the back stop portion of the hammer assembly. The hammer return spring mounting enables adjustment of the range of force applied by the spring to the hammer. The force range magnitude is such that the hammer return torque is commensurate to the torque that would be applied by gravity if the hammer shank were mounted horizontally instead of vertically. The operating force of the jack/repetition spring is related to that of the hammer return spring in such a way that re-engagement of the jack with the hammer butt is assured before hammer return beyond the back-checked point. The ends of the jack/repetition spring are geometrically located to allow the elements of the action to keep in intimate contact after re-engagement, making possible the elimination of the bridle tape and wire, and to provide a function that feels smooth and tight, not loose. The interaction between the springs as applied produces enough return force on the key to allow use of weights in the played end of the key to provide the desirable inertial resistance of a grand action to the player's touch on the keys. With the subject action properly adjusted, the hammer assembly rests upon the jack, rather than the traditional rest rail and therefore there is space between the hammer shank and hammer rest rail when the action is at rest.
摘要翻译：主题行为是传统直立动作的修改。传统的千斤顶弹簧被淘汰。其功能由千斤顶/重复弹簧来承担，千斤顶/重复弹簧是可调节地安装在接近锤头踵的端部附近的千斤顶之间的压缩弹簧和附接到锤组件的后止挡部分的导向器。锤回位弹簧安装使得能够调节弹簧施加到锤的力的范围。力范围大小使得如果锤柄水平而不是垂直安装，则锤击返回扭矩与由重力施加的扭矩相当。千斤顶/重复弹簧的操作力与锤复位弹簧的操作力相关，使得在锤返回超过后检点之前，可以确保千斤顶与锤子对接头的重新接合。千斤顶/重复弹簧的端部几何定位以允许动作元件在重新接合之后保持紧密接触，从而可能消除绷带和线，并且提供感觉平滑和紧密的功能，不松动弹簧之间的相互作用在钥匙上产生足够的返回力，以允许使用键的弹奏端的重量，以提供对玩家对钥匙的触摸的宏伟动作所需的惯性阻力。在主体动作适当调整的情况下，锤子组件靠在千斤顶上，而不是传统的休息轨，因此当动作静止时，锤柄和锤子休息轨之间有空间。
