摘要： An automatic player piano is broken down into an acoustic piano and an automatic playing system, and solenoid-operated key actuators are driven to rotate the black/white keys of the acoustic piano; the space between the keyboard and the array of black/white keys is so narrow that the manufacturer provides the solenoid-operated key actuators in the space below the key bed; plunger holes are formed in the rear portion of the key bed, and the solenoids occupy the space under the key bed so that the plungers project through the plunger holes into the space beneath the rear portions of the keys; the key bed is does not lose the mechanical strength so that the tuning work is not frequently required for the key action units.

摘要： An automatic performance device for a keyboard instrument such as piano, organ, cembalo and celesta includes operators such as keys and a pedal provided in a keyboard instrument for producing sounds, a target performance state designation unit for producing target performance information of the keyboard instrument, a real performance state detection circuit for detecting an operation state of the operators and producing a detection output, an actuator such as a solenoid for actuating the operators, and a control circuit for controlling the actuator. The control circuit detects in error between the detection output of the real performance state detection circuit and the target performance information, and generates an operator actuating signal by correcting the target performance information to eliminate the error and supplies the corrected operator actuating signal to the actuator.

摘要： A key striking force sensor suitable for player pianos.This sensor contains a displacement sensor for measuring displacement between the displacement sensor itself and a catcher which rocks together with a hammer. As the positions of the catchers corresponding to the hammer respectively are almost the same, plural of the displacement sensors can be mounted on a common circuit board. Accordingly, mechanical construction thereof is comparatively simpler than that of conventional player pianos.

摘要： A hammer movement detection device for detecting the movement of a hammer which strikes strings provided for each key of a keyboard musical instrument. The hammer movement detection device radiates light onto a hammer shank which moves with the hammer and detects at least the displacement of the hammer shank based on the light reflected from the hammmer shank. The movement detection device may be attached to a shank rail which supports the hammer shank in a freely rotatable manner. The hammer movement detection device may be supported using a fixed member which is supported above the hammer shank and below the pin board which is connected to the frame which supports the strings which are struck by the hammer.

摘要： A lever is supported by a lever supporting portion. The lever is urged by a first spring and a second spring. The urging force of the first spring varies over the entire operational range of the lever. The second spring and a third spring are provided serially through a movable supporting member. The displacement of the movable supporting member is restricted by a fixed supporting member. If the urging force of the second spring exceeds the urging force of the third spring, the restriction on the displacement of the movable supporting member is removed. Therefore, the present configuration provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.

摘要： A key structure includes a top plate which is formed by laminating a half-transparent resin surface layer member on a resin bottom side member using two-color injection molding, and the top plate is secured on a wooden key base. A plurality of concave grooves and protrusions, and a plurality of protrusion and troughs are respectively formed together in straight lines in the long direction of the key structure on a rear face of the surface layer member and a top face of the rear side member. Outside light is reflected from the top ends of the protrusion and the troughs, whereby a faint and natural vertically-striped pattern, which corresponds to a concave-convex part formed by the concave grooves and the protrusions, is perceived as resembling an edge grain of ivory.
