摘要： A keyboard apparatus that can be manufactured with a simple process at a low cost while still providing the feeling and appearance of high quality. In one embodiment of the invention, side surfaces of the white keys in the keyboard apparatus comprises a grained portion with a wood grain pattern. In this embodiment, when a white key is pressed down, the grained portion is visible from the side to give the appearance that the white keys are made from wood with a layer of white resin on the top and front surface. In another embodiment of the invention, a lower surface of a front end portion of the white keys is packed with a material such as resin. With this embodiment, when a performer's fingernail hits the top surface of the white keys while using the keyboard apparatus, the production of an unpleasant sound can be avoided.

摘要： A hammer with simplified structure and reduced costs that maintains its capability as a mass body to impart a touch weight. The hammer is configured such that it is possible to fix the two mass plates to the metal base plate by means of a single rivet. Therefore, the number of places in which the rivet holes are drilled and disposed in both mass plates and the metal base plate are kept to a minimum, and it is possible to limit the lightening of the weight of both mass plates and the metal base plate by that amount. As a result, since it is possible to configure the base plates and the metal base plate with smaller dimensions while maintaining the required weight, the capability as a mass body to impart a touch weight can be maintained while preventing the enlarging of the hammer overall.

摘要： A keyboard device capable of reconstructing a unique clicking sense of an acoustic piano is provided. A first incline portion (a plane or curved surface) of a sliding surface is inclined towards a direction gradually departing from a base portion of a protrusion along a displacement direction of the protrusion in a key-pressing operation for reducing a resistance exerted on the protrusion and suppressing a gradual increase of a sense of resistance. Moreover, a bump portion located at where the protrusion reaches after sliding through the first incline portion is used to increase the resistance exerted on the protrusion for increasing the sense of resistance. When the protrusion crosses over the bump portion, the sense of resistance is reduced. Accordingly, variation in the sense of resistance before and after the bump portion is increased, and the unique clicking sense of the acoustic piano is reproduced.

摘要： A keyboard device has a plurality of keys, each key having a support base where one end of each key is supported and is arranged to allow for movement, and a plate that hides the surface of the base. The keys are created with ultrasonic welding once the base and the plate merge. Thus, it is possible to weld while merging the base and the plate together, because the base and the plate are connected by ultrasonic welding. Compared to pasting the two together using traditional adhesives, it is possible to have the base securely bound to the plate. It is then possible to have performers use the device for an extended period of time. The result is the ability to curb the chances of the base and the plate becoming loose.

摘要： A keyboard apparatus is provided with a key unit that has a plurality of keys supported for pivotal motion. Also provided is a detection section for detecting a key speed when any of the keys are pivoted. The key unit and detection section are supported by a housing having a bottom member formed of a resin. A reinforcing member having a sufficient rigidity is provided to reinforce the bottom member of the housing such as to reduce warping of the bottom member so as to reduce movement of the detection section as a result of warping of the bottom member.
