PURPOSE:To decrease the number of input key switches and to ensure the input of many functions with high operability by moving a display sheet showing the key display corresponding to each function and setting the key display opposite to the corresponding key. CONSTITUTION:A display sheet 1 is moved with operations of key switches 8a - 8e of mode selection switches 8, and the detection areas 12a, 12b... of display parts 11a, 11b... corresponding to the selected modes are detected. Thus the sheet 1 is stopped. Then the key displays 16a, 16b... corresponding to the selected modes of the selected parts 11a, 11b... are set opposite to a pressure-sensitive key switch 22 of a keyboard 2. Thus the number of input key switches is decreased with operation of the switch 22. Then the input of many functions can be facilitated with high operability. |
