PURPOSE:To easily detect an operating means by allowing an illuminating means to turning on and off the display of a display operating part with a function belonging to a selected mode when the mode is selected by a mode selecting means. CONSTITUTION:The illuminating means LEDs 851-876 are arranged on the backs of respective display operation parts of a display means as back lights so that the ON, OFF and ON/OFF states can be observed from the front side of the display means. When a mode is selected by the mode selecting means, the displays on the display operation parts with the function belonging to the selected mode are turned on and off by the corresponding LEDs out of the LEDs 851-876, and when one of functions turned on and off is selected by a function selecting means, the selected function is set up. Thus, the function to be required to input can be clearly indicated to the operator by turning on and off the name of the function required at its input and pattern characters. |
