摘要： PROBLEM TO BE SOLVED: To enhance the rigidity without excessively increasing the mass of a hammer body. SOLUTION: A hammer body 20 is provided corresponding with each key 1 and comprised of a resin hammer base part 21 and a metallic pipe part 22. The pipe part 22 is manufactured with a member having a circular outer cross-sectional shape, and a flat modified cross-sectional part 22c1 is formed at the tip of a fixed side end part 22c to close an opening. In the hammer body 20, the fixed side end part 22c of the pipe part 22 is fixed to a pipe fixing part 21e of the hammer base part 21 by means of outsert molding when the hammer base part 21 is injection molded. The fixed side end part 22c achieves a rotation stop function relative to the pipe fixing part 21e by the presence of the modified cross-sectional part 22c1. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To easily and faithfully reproduce haptic characteristics in operation of an operator of one musical instrument on another musical instrument. SOLUTION: A key drive unit 20 drives and controls a key 31 at a fixed speed or with fixed acceleration and at respective positions obtained by dividing a stroke of the key 31 into a plurality of stages, necessary input current values ik corresponding to position signals xk in the driving are detected. Reaction forces F corresponding to the position signals xk in the respective stages are prescribed according to the necessary input current values ik and position signals xk, and an ik-F conversion table. Then a measured data table 61 is obtained by the driving at the fixed speed and a measured data table 62 is obtained by the driving with the fixed acceleration. Then tables are reconstituted based upon those measured data tables 61 and 62 and a haptic table group TBL is computed and output. COPYRIGHT: (C)2006,JPO&NCIPI
