To accurately grasp the consumption level of an electrical part.
In the case of a normal mode, when electric power is supplied to first and second load groups, a CPU 721 controls a time count part 725 so as to supply a first pulse-like time count signal of 1 Hz to first and second counter 726a, 726b. The first and second counter 726a, 726b receive a first clocking signal from the time count part 725 to count the number of pulse, and when it reaches 60, they send a second clocking signal consisting of one pulse signal to first minute counters 726p, 726q, and a second minute counter 726r respectively. Every time the first and second minute counters 726p, 726q, 727r receive the second clocking signal, they increase the count number by one to carry out clocking in a minute unit.
