<p>PURPOSE:To enable an operation to be continued by sending a signal to change a method to an input method from a keyboard to a control means when input from a touch panel is disabled, and switching a switching means to a keyboard input enabling state by the control means. CONSTITUTION:When the input from the touch panel 12 is disabled due to an unknown cause, the signal 17 which switches the input method by performing key input from the keyboard 13 is sent to an input control part 6. Thereby, the input control part 6 sends a switching signal 18 to a soft switch 9, and connects the switch 9 to a keyboard 13 side, and a main control part 5 and a display control part 7 make a CRT 11 display a command so as to enable key input to be performed in the same equation as the input state from the touch panel 12. A command is inputted from the keyboard 13 according to the display of the command, then, it is executed. In such a way, input indication can be issued instead of the touch panel 12 and the operation can be continued.</p> |
