<p>PURPOSE:To display the consumption state of a power supply in terms of a meter by displaying in steps the voltage level state of a battery on a display screen for the power supply state based on the deciding result of a deciding device for voltage level after a display request detecting device detects a display request for the power supply state. CONSTITUTION:A state screen display device 17 gives an instruction to a display part 13 to display a power supply state display screen together with an operation screen when a display request detecting device 15 detects a request for display of a power supply state. Then the voltage level state of a battery 11 is displayed in steps on the power supply state display screen so that the number of lit elements is decreased in response to the reduction of the voltage level, for example, in accordance with the deciding result of a voltage level deciding device 16. In such a manner, the voltage state of the battery 11 is displayed in steps by means of the part 13 where the operation screen is displayed. Thus the consumption state of the battery 11 is displayed in terms of a meter.</p> |
