PROBLEM TO BE SOLVED: To assume the presence of a user without using a sensor and to perform an optimum operation by automatically changing the contents of stored setting data to prescribed data when a clock means clocks the prescribed time. SOLUTION: A RAM 58 stores the set time data of the time band of automatic power OFF and a CPU 55 inputs the time data from an IC 63 for a clock. Then, in the case of the absence time and time = 0, since it is assumed that the absence time newly starts, a timer value TIME 2 for the absence time is set to a timer TIME for the automatic power OFF, '1' for indicating the absence time is substituted for the time and then, a processing for changing a setting value is performed. In the case of the presence time and time = 1, since it is assumed that the presence time newly starts, the timer value TIME 1 for the presence time is set to the timer TIME for the automatic power OFF, '0' for indicating the presence time is substituted for the time and then, the processing for returning the setting value to a set value is performed. |
