ABSTRACT:
There is provided a performance apparatus that is capable of reducing mechanical noise by a simple construction. Rotary picks are disposed in the vicinity of and in association with respective ends of a plurality of reeds, and four driving nails are formed integrally with outer peripheries of the rotary picks. A hook part is attached to the top of a plunger, and they make reciprocating motions together. The rotary pick is rotated by a driving force applied to the driving nail thereof from an engaging part formed by a lower end of the corresponding hook part. When the driving nail located symmetrically to the driving nail having received the driving force plucks the corresponding reed, the reed is sounded. The hook part is almost completely covered with a cushioning member formed of an elastic material such as rubber to absorb an impact that may occur when the driving nail of the rotary pick comes into contact with the hook part.
