<p>PROBLEM TO BE SOLVED: To generate a key code signal through only foot operation. SOLUTION: When a 2nd pedal 10 is oscillated in vertical and horizontal planes, corresponding to the oscillating position of the 2nd pedal 10, a position signal generating means 12 generates X and Y-coordinate signals. Based on the X and Y-coordinate signals, a 1st key code signal generating means 50 generates key code signals corresponding to the respective keys of a keyboard, and based on two position signals generated by the position signal generating means 12, a 2nd key code signal generating means 52 generates key code signals corresponding to respective keys, when the shift key of the keyboard is depressed. A 3rd key code signal generating means 54 similarly generates key code signals corresponding to respective keys, when a control key is depressed. When 1st-3rd buttons 6A-6C are respectively depressed, 1st-3rd key code signal output means 56, 60 and 62 output these key code signals to a 1st signal output interface 58A.</p> |
