摘要： A composite part for an electronic musical instrument which allows the center of a drill to be immediately and reliably positioned on a rivet during disassembly, thereby making it possible to significantly improve the efficiency of disassembling works and accordingly promote reuse of resources. The composite part is composed of first and second members each having a rivet inserting hole, and a rivet having a head and a shaft. The rivet is inserted through the rivet inserting holes of the first and second members, and a leading end portion of the shaft is caulked to join the first and second members together. The rivet is formed with a guiding recess formed on a surface of at least one of the head and the caulked leading end portion of the shaft for guiding a drill for cutting the rivet when the first and second members are disassembled.

摘要： A keyboard device for a keyboard-based musical instrument comprises a plurality of chassis arranged in a left-to-right direction, and a plurality of keys attached to the plurality of chassis for pivotal movements and arranged in the left-to-right direction. The overall chassis for the keyboard device is divided into a plurality of chassis which can be separately manufactured, so that the size of each chassis can be reduced as compared with a conventional keyboard device for which a single chassis is manufactured. Since this results in a reduction in scale of manufacturing facilities including a mold and a press machine used for manufacturing the chassis, and easier adjustments to the mold in a trial manufacturing stage, a manufacturing cost of the chassis, i.e., a manufacturing cost of the keyboard device can be reduced.
摘要翻译：一种用于基于键盘的乐器的键盘装置包括沿左右方向布置的多个机架，以及附接到多个机架的多个键，用于枢转运动并沿左右方向布置。用于键盘装置的整个底盘被分成可以单独制造的多个底盘，从而与制造单个底盘的常规键盘装置相比，可以减小每个底盘的尺寸。由于这导致制造设备的规模的缩小，包括用于制造底盘的模具和冲压机，并且在试制作阶段更容易地调整模具，底盘的制造成本，即制造成本键盘装置可以减少。

摘要： A keyboard apparatus for an acoustic piano having strings includes keys, a key bed supporting the keys such that they are turnable thereon, an action mechanism arranged at a rear end portion of each of the keys which operates in a manner interlocked with key depression to strike the associated string to generate a musical tone, and a key sensor switch mounted on the key bed for generating key depression information of the keys. The key sensor switch is formed by a rubber switch, and removably mounted on the key bed. Alternatively, the key sensor switch is movably mounted on the key bed such that the key sensor switch can be moved between a detecting position in which the key sensor switch can be depressed by any key depressed, and a non-detecting position in which the key sensor switch cannot be depressed by any key depressed.

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： A keyboard instrument is provided which inhibits generation of unintended, audible noise. A partition (body part) is arranged between adjacent hammers corresponding to keys. In the keyboard instrument provided with the partition, even if the keyboard instrument is rotated vertically and a hammer falls, the partition prevents the hammer from freely falling and striking adjacent hammers. Also, the hammer is restricted from generating unintended sounds for reasons unrelated to falling. Accordingly, generation of an unintended audible sound of the hammers can be reliably restrained in the present keyboard instrument.

摘要： A plate-like member or rib 19 is extended in a back-to-front direction of a key 14. The height of a rear end of a flat portion 12 is regulated by an upper flange portion 21c and a lower flange portion 22 of the rib 19. A wippen 30 provided with a jack 44 is attached via a bearing member 33 for supporting a wippen swing axis 31 onto a chassis 11. A hammer 50 is attached via a center rail 60 provided with a bearing member 65 for supporting a hammer swing axis 51 onto the chassis 11. A bearing 16 for supporting a key support 15 is fixed to the chassis 11 with a flange portion 61 of the center rail 60 abutting on a rear L-shaped leg 18. A substantially L-shaped rail 67 is fixed with a screw on the center rail 60, which has on its top face a hammer cushion 68 for abutting a rest portion 52 of the hammer 50 and on its lower face a regulating felt for abutting on a hack tail 47. The wippen 30 has a long swing radius, and therefore a larger inertial moment by a weight 41, as compared with the jack 44 and the hammer 50. The rest portion 52, a butt portion 53 and a catcher portion 54 are provided on a continuous face of the hammer 50. A cushion material 56 constituted of a urethane foam layer for absorbing impact and an artificial leather layer providing slidability is placed on the continuous face. The key support 15 is provided between a sliding tape 32 of the wippen 30 and a jack axis 45.
