<p>PROBLEM TO BE SOLVED: To provide a radio receiver enabling, in battery exhaustion, reception and reproduction by replacing a battery even if the battery to be required for replacement is shortage.SOLUTION: An emergency radio receiver 10 includes: a fist battery housing unit 46 that houses even number batteries, for example, four batteries so as to arrange in a vertical direction and a lateral direction two by two and connect in series; and a second battery housing unit 48 that houses odd number batteries, for example, three batteries less than the four batteries as an even number so as to arrange in the lateral direction and connect in series, and a required number of batteries is housed to any one of the battery housing units. A power supply circuit unit converts a first battery voltage housed to the first battery housing unit 46 and inputted from the four batteries connected in series or a second battery voltage housed to the second battery housing unit 48 and inputted from the three batteries connected in series to a predetermined constant voltage, and outputs it.</p> |
