摘要： A surface 60 of a butt 50 has a flat portion 61 which is situated forward and has a small inclination angle and a slanting pressure receiving portion 62 which is situated backward and has a large inclination angle as areas pushed up by a jack 40. Between the flat portion 61 and the slanting pressure receiving portion 62, an escapement portion 63 having an obtuse angle is formed. The escapement portion 63 is provided to correspond to a position of the jack 40 placed immediately after the start of swinging of the jack 40. The inclination angle of the slanting pressure receiving portion 62 is determined such that in a stage where a key starts returning from a slow full stroke key-depression, a position at which the butt 50 is in contact with the jack 40 is maintained with the butt 50 swinging backward.

摘要： A lever 40 is supported by a lever supporting portion 41. Through a first pivoting member 52, the lever 40 is urged by a reaction force stabilization spring 54, a first spring 55 and a second spring 56. The downward displacement of a second pivoting member 53 is restricted by a fixed supporting member FR. If the urging force of the first spring 55 exceeds the urging force of the second spring 56, the second pivoting member 53 is displaced upward. A contact member which is in contact with the first pivoting member 52 and the second pivoting member 53 to produce friction force is also provided.

摘要： An automatic playing system is independent of acoustic pianos, and is designed to perform music tunes expressed by sets of MIDI music data codes on the acoustic pianos; since the acoustic pianos have their own individualities, control parameter table, which were prepared through experiments on a standard piano, are not optimum for most of the acoustic pianos due to the individualities: the automatic playing system can tailor the control parameter tables defining relation between the magnitude of driving signal and the MIDI velocity and relation between the magnitude of driving signal and time lag from the supply of the driving signal and the collision between the hammers and the strings for each sort of acoustic pianos before the automatic playing so that the automatic playing system reproduces the music tunes at high fidelity regardless of the sort of acoustic pianos.

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： There is provided an operator member displaceable, in response to operation by a human operator, relative to at least one displacement axis (more preferably, multi-dimensionally). Operating state of the operator member is detected and model operation information, indicative of an operating state to be taken by the operator member, is generated, so that reaction information is generated in accordance with a difference between the detected actual operating state and an operating state indicated by the model operation information. Reactive force is imparted to the operator member in accordance with the generated reaction information. In this way, a model operation amount can be informed to the human operator in the form of the reactive force. Further, by imparting separate reactive forces to a multi-axially operable operator member, appropriate information can be provided to the human operator during operation of the operator member, thereby achieving sensory feedback to the human operator.
