摘要： The keyboard apparatus is constituted by a series of units in which key stems are connected to a key support section through a connection section. The width of the connection section is wider than a width of the back-end of the key stem attached to the connection section, and the units are stacked vertically so that the connection sections partially over lap. White keys are arranged in a plurality of upper key units and lower key units, having key stems, connection sections and support sections, which are transversely linked to one another. In a keyboard in which the lower key units are stacked in such a way that the key support section of the lower key units are underneath the key support sections of the upper key units, the back-ends of the key stems are joined to the transverse midpoints of connection sections. The keys are arranged so that the lateral surfaces of the key stems in adjacent upper key units are disposed substantially in one common plane.

摘要： A keyboard assembly includes a plurality of white keys and black keys juxtaposed to each other and each having a body disposed to be depressed, and a connecting portion, and a key support that supports the body. The connecting portion connects the body to the key support in a fashion permitting the body to swing in directions of key depression and release while limiting lateral motions of the body. The body of each of the white keys has an extension formed integrally therewith and laterally extending therefrom at a location under the body of a corresponding one of the black keys in such a manner that the extension overlaps with the bottom surface of the body of the corresponding one of the black keys.

摘要： A switch apparatus has a fixed contact including a contact pattern formed on a printed substrate and a movable contact provided above and opposing the fixed contact. A switching operation is performed by engaging the movable contact with the fixed contact. The fixed contact pattern has a first pair of fixed contacts and a second pair of fixed contacts. The fixed contact patterns are separated by a predetermined distance from one another. The movable contact has a first movable contact and a second movable contact for engagement with the first and the second pairs of fixed contacts, respectively. One of the first pair of fixed contacts and one of the second pair of fixed contacts are formed in a unit to define a common pattern. Only the common pattern is disposed between the other of the first pair of fixed contacts and the other of the second pair of fixed contacts.

摘要： The electronic musical instrument is constructed such as to detect key-on/key-off performed by physical flexion movements of fingers through a pair of performing gloves 1 and 2 so as to effect generation and erase of musical tones in real timings practically matching with fingering performance. An A/D converter 3 converts signals from bend sensors 10 of the performing gloves 1, 2 into digital flexion data. A controller 4 processes the digital flexion data such as to detect a stop motion of a finger to judge a key-on event according to bending velocity information calculated from the sequentially sampled flexion data, thereby generating musical tones. Further, the controller 4 detects a maximum angle according to the flexion data of the finger restored from the key-on state so as to judge a key-off event according to an off-threshold level correlated to the maximum bend depth to thereby erase musical tones.

摘要： A keyboard apparatus with at least one key having a rotation fulcrum and an exterior front end face on the opposite side of the rotation fulcrum in a performer side. The exterior front end face of the at least one key defines a front lower section. An extended section is provided at the front lower section of the at least one key that extends from the exterior front end face of the at least one key toward the performer side, and a mass member is attached to the extended section. The mass member therefore extends forwardly from the external front end face of the at least one key toward the performer side.

摘要： A keyboard assembly comprises at least one key unit including a plurality of keys each having a front end and a base end, a common key support supporting the keys, and a connecting portion provided on the base end of each of the keys and connecting between each of the keys and the common key support. The keys are formed integrally with the connecting portion and the common key support in a manner such that the keys are each connected via the connecting portion to the common key support for swinging about the common key support in a direction of depression and release of the keys and in a direction in which the keys are juxtaposed. The keys define gaps therebetween, each of which becomes progressively larger toward the front end of an associated one of the keys. Guided projections are provided on the keys, and guides on a frame in which the key unit is mounted, for causing the keys to run parallel with each other by deforming the connecting portion of each of the keys to thereby engage the key unit with the frame.

摘要： A keyboard apparatus is constructed on a frame having a plurality of support members. A plurality of keys are movably supported by the corresponding support members such that each key can be operated by a finger action to undergo a primary stroke movement. A plurality of mass members are disposed in the frame. Each mass member is linked to a corresponding key for undergoing a secondary stroke movement in response to the primary stroke movement of the corresponding key so as to impart a dynamic reaction to the finger action. A stopper member is disposed in the frame not only for directly fixing a limit of the secondary stroke movement of each mass member, but also for indirectly fixing a limit of the primary stroke movement of the corresponding key. Further, a plurality of guiding members are arranged in the frame remotely from the support members and correspondingly to the respective keys. Each guiding member is shaped in point contact with the corresponding key so as to guide the primary stroke movement thereof.

摘要翻译： 键盘装置构造在具有多个支撑构件的框架上。 多个键由相应的支撑构件可移动地支撑，使得每个键可以通过手指动作来操作以进行初级行程。 多个质量构件设置在框架中。 每个质量构件连接到对应的钥匙，以响应于相应钥匙的主冲程运动而进行二次冲程运动，从而对手指动作产生动态反应。 在框架中设置止动构件，不仅用于直接固定每个质量构件的次冲程运动的极限，而且用于间接地固定相应键的主冲程运动的极限。 此外，多个引导构件被布置在框架中远离支撑构件并且对应于各个键。 每个引导构件成形为与对应的键点接触，以便引导其初级行程。
