ABSTRACT:
A separate automatic player is independent of a piano, and stands in front of the piano for an automatic playing; the separate automatic player includes a key driver unit, a pedal driver unit and a framework on which the key driver unit and pedal driver unit is carried; the key driver unit has an array of key actuators so as to selectively depress and releases the black and white keys, and a pair of side elevators and a rotary unit is provided between the framework and the array of key actuators; the side elevators bring the plunger heads of the key actuators into contact with the upper surfaces of the black and white keys, and the rotary unit makes the plungers vertical to the upper surfaces so that the key actuators exert force on the black and white keys at the magnitude exactly equivalent to pieces of music data.
