摘要： Keyboard apparatus includes: a key supported for pivoting movement about a pivot point; a mass member for imparting a reaction force to performance operation of the key in interlocked relation to the key; a transmission member provided in abutment with both of the key and mass member to transmit a load from one of the key and mass member to the other; and an electromagnetic actuator for driving, via a fixed coil, the transmission member toward at least one of the key and mass member. Good key touch feeling can be achieved not only by a load applied from the mass member to the key but also through load control by the actuator. Thus, it is possible to faithfully reproduce a key touch feeling approximate to that in a natural keyboard instrument, such as an acoustic piano, with a simple construction and facilitated control.

摘要： 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.
