Abstract

PROBLEM TO BE SOLVED: To provide an apparatus which requires no excessive operation to user and can automatically make a power source off at a time when it is convenient for individual users. SOLUTION: When the power source is turned on in S1, whether it is a learning period or not is checked in S2. When it is judged as a learning period, a measurement part 61 starts the counting of current-carrying time. Whether the turning-off operation of the power source has been performed or not is checked in S4. When it is judged as a turning-off operation, the time counting by the measurement part 61 is ended in S5, and the measurement result is stored in a memory part 62. When the learning period is ended, a control means 4 retrieves the longest current-carrying time from the memory part 62, and sets this time as continuous current-carrying time in a current-carrying time setting part 2.
