<P>PROBLEM TO BE SOLVED: To faithfully regenerate performance feeling of a natural keyboard instrument, which has a feature in each operation of a key and a damper pedal, and their reaction forces are related to each other in a prescribed operation range. <P>SOLUTION: An electronic keyboard instrument includes: a key 11 and a pedal 31; solenoids 20 and 40 which correspond to them; a key position sensor 25 and a pedal position sensor 45; haptic force applying tables 81 and 82 for the key and the pedal; and a control section 50 for controlling reaction force generated at solenoids 20 and 40 on the basis of the haptic force applying tables 81 and 82. On the basis of determination whether or not, a detection value of the pedal position sensor 45 exceeds a prescribed threshold, the control section 50 selects either of first or second tables 81-1, 81-2 included in the haptic applying table 81 for a keyboard, and controls reaction force to operation of the key 11, which is generated at the solenoid 20, on the basis of the selected table 81-1 or 81-2, and a detection value of the key position sensor 25. <P>COPYRIGHT: (C)2010,JPO&INPIT |
