(Step 13), the process returns to Step 2.
If there is an interrupt indicating that a return factor has been detected in the process from step 6 to step 13 (step 2; Y), the normal operation mode is always returned (step 3).
According to this embodiment, the power source that is supplied without interruption to the recovery factor detector 2 is selected and used as the power source with the lowest power consumption, so that the power consumption can be reduced.
In addition, when the rechargeable battery state detection unit 5 detects that the state of the rechargeable battery 4 has fallen below a predetermined value, the rechargeable battery 4 has a charge source selection / switching unit 7 that selects and switches the charge source to the rechargeable battery 4. Therefore, even if the rechargeable battery 4 is discharged, the rechargeable battery 4 can be charged with the optimum power source 6 because the rechargeable battery is charged with the power source with the least power consumption that can be used from among the plurality of power sources 6. , Power consumption can be reduced.

省エネモードにおいて、復帰要因検知部２が省エネモードから通常モードへの復帰要因を検知しなければ（ステップ２２；Ｎ）、省エネ状態のままである。そして、充電池４の状態が所定の値を下回ったことを充電池状態検知部５が検知しなければ（ステップ２５；Ｎ）、充電池４から復帰要因検知部２への電力供給で省エネ状態を保つ（ステップ２２）。 Next, a second embodiment will be described.

充電池４の充電が終了したことを充電池状態検知部５が検知しなければ（ステップ５２；Ｎ）、充電池４の充電を続ける（ステップ５１）。
充電池４の充電が終了したことを充電池状態検知部５が検知すれば（ステップ５２；Ｙ）、復帰要因検知部２への電力源を選択し切り替える電源選択・切り替え部８により、充電池４の復帰要因検知部２への電力供給をオンし（ステップ５３）、ここまで復帰要因検知部２に電力を供給していた、複数の電力源６の中で最小の消費電力のバスパワーをオフする（ステップ５４）。そして、充電池４への充電元として選択し切り替える充電元選択・切り替え部７により、これまで充電池４を充電していた、複数の電力源６の中で最小の消費電力のバスパワーをオフし（ステップ５５）、ステップ４２へ戻る。 On the other hand, the rechargeable battery state detection unit 5 detects that the state of the rechargeable battery 4 has fallen below a predetermined value (step 45; Y), and the power source detection unit 9 detects a usable power source (step) 46; Y), and when the bus power is detected as the usable power source (step 47; Y), the power source selection / switching unit 8 selects and switches the power source to the return factor detection unit 2 to select a plurality of powers. The bus power with the minimum power consumption in the source 6 is turned on (step 48), and the rechargeable battery 4 turns off the power supply to the return factor detector 2 (step 49).

If the rechargeable battery state detection unit 5 does not detect that the charging of the rechargeable battery 4 has been completed (step 52; N), the rechargeable battery 4 is continuously charged (step 51).
When the rechargeable battery state detection unit 5 detects that the charging of the rechargeable battery 4 has been completed (step 52; Y), the rechargeable battery is selected by the power source selection / switching unit 8 that selects and switches the power source to the return factor detection unit 2. 4 to turn on the power supply to the return factor detection unit 2 (step 53), and to supply the power to the return factor detection unit 2 so far, the bus power of the minimum power consumption among the plurality of power sources 6 Turn off (step 54).

When the bus power is not detected as the usable power source (step 47; N), the bus power is not detected at all, while the usable AC power source is detected ( Step 56).
Here, the AC power source is turned on by the power source selection / switching unit 8 that selects and switches the power source to the recovery factor detection unit 2 (step 57), and the rechargeable battery 4 is restored by the power source selection / switching unit 8. The power supply to 2 is turned off (step 58). Then, the AC power source is turned on by the charging source selection / switching unit 7 that is selected and switched as a charging source for the rechargeable battery 4 (step 59), and the rechargeable battery 4 is charged (step 60).
If it is not detected that the charging of the rechargeable battery 4 has been completed (step 61; N), the charging of the rechargeable battery 4 is continued (step 60).
On the other hand, when the rechargeable battery state detection unit 5 detects that charging of the rechargeable battery 4 has been completed (step 61; Y), the power source selection / switching unit 8 selects and switches the power source to the return factor detection unit 2 to charge The power supply to the return factor detector 2 of the battery 4 is turned on (step 62).
