PURPOSE:To prevent a power supply from left unapplied or uninterrupted by providing a clock means and a switch means. CONSTITUTION:A power supply of a reception section 3 is supplied from a battery 7 via a switch section 6. The switch section 6 turns on/off the power supply to the reception section 3 according to a control signal from a clock section 8. An operating time setting section 9 sets a time outputting the control signal and a time revision section 10 revises a correct time. For example, after matching the time of the clock section 8 accurately, the time revision section 10 uses the operation time setting section 9 to set the start time to 9:00 and the end time to 17:00. Thus, the state of disabling the reception due to the power supply left unapplied is evaded. Moreover, the useless consumption of the battery 7 due to the power supply left uninterrupted is prevented. |
