ピアノ自動演奏装置のアクチュエータ。A solenoid coil is wound around a bobbin and is energized based on information such as the movement of keys on a piano keyboard.
a yoke that becomes a magnetic path when the coil is excited; a plunger formed in a stepped shaft shape and movable in the bobbin axial direction using the inner surface of the bobbin as a guide surface; and a spring that supports the plunger. A piano comprising: an actuator head attached to the tip of the narrow diameter portion of the plunger; and an auxiliary yoke that also serves as a stopper and is provided overlappingly on the upper surface of the yoke so that its inner peripheral end protrudes inward from the inner surface of the bobbin. Actuator for automatic performance equipment.
