摘要： A keyboard weight includes a weight body formed in a cylindrical shape. A groove is formed in a peripheral edge portion of an end face of the weight body, the groove extending along a peripheral edge of the end face, the end face being perpendicular to an axial direction of the weight body, and an outward inner surface of the groove among inner surfaces of the groove slopes toward outside of the weight body from a bottom portion of the groove toward an opening in the axial direction, the outward inner surface facing toward inside of the weight body in the radial direction, and an inclination angle of the outward inner surface is 30° or greater relative to the axial direction.

摘要： A piano key assembly (11) with an elongated body (12)having a first key end (13) and a second key end (15). The first key end defines a playing surface (14) and the opposite second key end is for actuation of a piano hammer. A weighted member (16) is provided, which is adjustably attached to an adjustment region (17) at the second key end. A piano can be equipped with such piano key assemblies, wherein the piano key assemblies are arranged on a balancing rail (8) defining a balancing surface. The force required to depress the piano keys can be adjusted by the presented method, wherein the weighted member are displaced within the adjustment region.

摘要： A key unit (KU) having a white key unit and a black key unit in which main bodies of a plurality of white keys (20) and black keys, (40) respectively, are coupled to respective common key support parts (30) via coupling parts (24, 42) pivotably in a key depression direction is mounted on a keyboard frame (10). In the black key unit, a total width in a key arrangement direction of each of the coupling parts (42) is wider than a key width of the black key main body, whereby the coupling parts (42) restrict yawing in a key width direction when the black keys (40) are depressed/released. In the white key unit, each of the coupling parts (24) is narrower in total width in the key arrangement direction than each of the coupling parts (42) in the black key unit, and guide parts (12) are provided on free end sides of the white keys (20) to restrict yawing in the key arrangement direction.

摘要： A key structure includes a top plate which is formed by laminating a half-transparent resin surface layer member on a resin bottom side member using two-color injection molding, and the top plate is secured on a wooden key base. A plurality of concave grooves and protrusions, and a plurality of protrusion and troughs are respectively formed together in straight lines in the long direction of the key structure on a rear face of the surface layer member and a top face of the rear side member. Outside light is reflected from the top ends of the protrusion and the troughs, whereby a faint and natural vertically-striped pattern, which corresponds to a concave-convex part formed by the concave grooves and the protrusions, is perceived as resembling an edge grain of ivory.

摘要： A high-quality keyboard device for a keyboard instrument, which can be manufactured by a simplified manufacturing process and at reduced manufacturing costs. A keyframe is formed by a molded piece of a synthetic resin. A plurality of front rail pins and a plurality of balance rail pins are arranged in a juxtaposed manner in a left-right direction at a front part and a central part of the keyframe in a front-rear direction. A plurality of keys are made of wood and each have a balance rail pin hole formed in a central portion thereof in the front-rear direction. A first reinforcing member and a second reinforcing member are made of metal and provided in the vicinity of the balance rail pins and the front rail pins for reinforcement of rigidity of the keyframe. The keys are swingably supported on the keyframe in a state where the balance rail pins are each engaged with the balance rail pin hole associated therewith and at the same time the keys are prevented from being swung in the left-right direction by the front rail pins associated therewith.

摘要： A key structure which is capable of giving a woody appearance to the key, and increasing the freedom of mounting at least one functional part formed as a separate part from the key structure, while maintaining excellent machinability. An upper plate has an increased width part corresponding to an end of a white key toward a player. In the key structure, a wood part is secured to the lower surface of at least the increased width part of the upper plate, and has an increased width part having substantially the same width as the increased width part of the upper plate. The key structure is mountable in a keyboard apparatus, for functioning as a white key pivotally moved by key-depressing operation. A recess is formed in a part of the wood part including the increased width part, which opens downward and has a width (W0) not less than 50 % and not more than 80 % of the width (B0) of the increased width part of the wood part.
