ABSTRACT:
An automatic playing apparatus is provided for an acoustic piano for reproducing a music without fingering of a player on a keyboard, and has a pedal actuator unit directly supported by a floor so that a reaction of the pedal is never exerted to the piano case, thereby preventing the key bed from deformation due to the reaction.
