摘要： A music rack unit-mounting structure of a grand piano, for removably mounting a music rack unit on a piano body of the grand piano. Rear ends of a left-side engagement portion and a right-side engagement portion are configured to be capable of being placed on front ends of a left-side guide portion and a right-side guide portion from above, respectively, when the music rack unit is mounted on the piano body from the front. By sliding the music rack unit rearward from the placed state, the music rack unit is mounted on the piano body, while the left-side engagement portion and the right-side engagement portion are fitted on or in the left-side guide portion and the right-side guide portion, respectively.

摘要： This invention discloses a light assembly containing preferably an LED light strip that rests at either side of the piano keys and spans the entire keyboard. The assembly is controlled by an infinitely variable light dimmer mounted at either side of the keyboard powered directly from either a 110 v AC outlet or from a rechargeable battery built into the same casing that houses the dimmer. Optionally, the invention can comprise a music rack light, controllable by the user. This optional music rack light has its own infinitely variable light dimmer, which is housed in the same casing as the piano keyboard light dimmer assembly and operates off the same battery or power source. This invention enables a pianist to easily see the keys in any lighting situation without interfering with the pianist's ability to play the piano or keyboard.
摘要翻译：本发明公开了一种轻型组件，其优选地包含一个LED灯条，其位于钢琴键的任一侧并跨越整个键盘。组件由安装在键盘两侧的无级可变光调光器控制，键盘直接由110V交流电源插座供电，或者由内置在容纳调光器的同一个外壳中的可充电电池供电。可选地，本发明可以包括由用户控制的音乐架灯。这种可选的音乐架灯具有自己的无级变化的调光器，它与钢琴键盘灯调光器组件在同一个外壳中，并且操作相同的电池或电源。本发明使得钢琴家能够轻松地在任何照明情况下看到琴键，而不会妨碍钢琴演奏钢琴或键盘的能力。

摘要： A device for presentation of musical concepts includes a scale plate having a periodical 12-step scale with equally spaced symbols for 12 notes with half-note intervals, wherein symbols of 12 consecutive notes form an octave. The device also includes at least one pointer plate, which includes a start symbol. The pointer plate is configured to revolve with respect to the scale such that the start symbol is settable to align with the symbol of any of the 12 notes of the scale. The pointer plate includes 7 pointers specific to a given class of keys wherein, when the start symbol points to a base note of a key, the pointers specific to the class of keys point to the symbols of the notes of the key beginning at the base note.
摘要翻译：用于呈现音乐概念的装置包括具有周期性12步刻度的刻度盘，其具有等间距的符号，用于具有半音符间隔的12个音符，其中12个连续音符的符号形成八度音阶。该装置还包括至少一个指针板，其包括起始符号。指针板被配置为相对于刻度旋转，使得开始符号可设置为与刻度的12个音符中的任一个的符号对准。指针板包括特定于给定类别键的7个指针，其中当起始符号指向键的基准时，特定于键类的指针指向从基础开始的键的音符的符号注意。

摘要： Anatomic rests are provided for a user of a device, including keyboards, drawing devices, and knitting machines. Anatomic rests receive at least the arm, hand, or wrist of the user. The rests are mounted in a manner providing rotation and translation relative to the utilization device. A support extends in front of the utilization device, the support having an upper horizontal surface defining a plane in permanent contact with anatomic rest rotation and translation components. The present system allows for controlled fore and aft movement with respect to the utilization device, as well as lateral movement along a horizontal axis. Rotation is enabled about a second axis so that it is substantially perpendicular to the first.

摘要： A key striking force sensor suitable for player pianos.This sensor contains a displacement sensor for measuring displacement between the displacement sensor itself and a catcher which rocks together with a hammer. As the positions of the catchers corresponding to the hammer respectively are almost the same, plural of the displacement sensors can be mounted on a common circuit board. Accordingly, mechanical construction thereof is comparatively simpler than that of conventional player pianos.
摘要翻译：一种适合演奏者钢琴的重要力量传感器。该传感器包含位移传感器，用于测量位移传感器本身和与锤子一起摇摆的捕手之间的位移。由于与锤相对应的捕捉器的位置几乎相同，因此可将多个位移传感器安装在公共电路板上。因此，其机械结构比常规的演奏者钢琴相当简单。
