| 20100326257 | KEYBOARD APPARATUS - In a keyboard apparatus including a key supported for pivoting movement about a pivot point, a mass member that imparts a reaction force to performance operation of the key in interlocked relation to the key, and an electromagnetic actuator provided between the key and the mass member for imparting a driving force to the key and mass member, a transmission member is provided in detachable abutment with the key and mass member. The transmission member can be disengaged from the key or the mass member depending on operating conditions of the key and the mass member. Thus, it is possible to not only prevent unnecessary binding forces from acting in areas where the transmission member and the key and the mass member abut against each other, but also achieve smooth movement of the key and the mass member and prevent increase of inertial mass of the transmission member. The smooth movement of the key and mass member can achieve force sense control with good responsiveness. Further, the key is pivotable in a key depressing direction as a reaction force imparted from the mass member is reduced by impartment, to the key, of a driving force by the actuator. Thus, the apparatus can perform both force sense control on depression operation of the key and an automatic performance involving automatic operation of the key, through cooperation between a reaction force imparted from the mass member to the key and the driving force imparted from the actuator to the key. | 12-30-2010 |

| 20080245216 | KEYBOARD PROCESSING SYSTEM AND METHOD - Embodiments of the keyboard system that can determine accurate key operation. The system provides immediate processing of the data input streams from various strike sources, the key stroke depth data, the key strike speed data, the key strike acceleration data. The movement state volume V can be calculated using a formula shown below, based on the key strike depth D, the key speed S, the key acceleration A, the coefficient a, b, c, and constant d. V=a*D+b*S+c*A+d. When the volume level exceeds the predetermined level A, the system determines that the key has been pressed. When it is determined that the key has been pressed, the “note-on” information is outputted to the sound source. The velocity value included in the “note-on” information is calculated with reference to the velocity curve based on the key speed when it is determined that the key has been pressed. | 10-09-2008 |
