PROBLEM TO BE SOLVED: To suppress the temperature rise of an enclosure by using a simple configuration without adding a temperature sensor.SOLUTION: A first information table 131 associates and stores each of a plurality of communication states A-D with enclosure surface temperature when a communication unit 120 is operated in each of the plurality of communication states A-D. An enclosure surface temperature acquisition unit 153 acquires enclosure surface temperature corresponding to any communication state acquired by a communication state acquisition unit 152 from the first information table on the basis of any of the communication states A-D acquired by a communication state acquisition unit and the information stored in the first information table. An enclosure surface temperature comparison unit 154 compares the enclosure surface temperature acquired by the enclosure surface temperature acquisition unit with the maximum value of enclosure surface temperature. A communication state control unit 155 selects any of the communication states stored in the first information table on the basis of the comparison result of a specific place temperature comparison unit and operates a communication unit in the selected communication state.SELECTED DRAWING: Figure 1 |
