Patent ID: 7355109

Claim:
A separate automatic player independent of a keyboard musical instrument having a fore-and-aft direction, a lateral direction crossing said fore-and-aft direction at right angle and an up-and-down direction normal to a plane defined by said fore-and-aft direction and said lateral direction, comprising: a key driver unit including a key actuator unit having an array of key actuators selectively driving keys of said keyboard musical instrument for producing tones, a first regulator connected to said key actuator unit and moving said key actuator unit in said up-and-down direction so as to make said array of said keys in parallel to the upper surfaces of said keys, and a second regulator connected to said key actuator unit and rotating said key actuator unit about a lateral line extending in parallel to said lateral direction so as to vary an angle between centerlines of said key actuators and a virtual plane defined by said lateral line and a vertical line normal to a floor where said keyboard musical instrument stands; and a pedal driver unit selectively stepping on pedals of said keyboard musical instrument.
