<P>PROBLEM TO BE SOLVED: To quickly raise temperature of a hearing element by suppressing heat transmission to a heat radiating plate when temperature of the heating element is low and radiate heat by accelerating heat transmission to the heat radiating plate when temperature of the heating element is high. <P>SOLUTION: This device is equipped with: the heat radiating plate 110; a support member 120 supporting the heat radiating plate 110 and the heating element 200, while keeping the both separate; and a heat transmission member 130 disposed between the heat radiating plate 110 and the heating element 200, separating from at least one of the heat radiating plate 110 and the heating element 200 when temperature of the heating element 200 is lower than predetermined temperature, and keeping contact with both of the heat radiating plate 110 and the heating element 200 when temperature of the heating element 200 is higher than the predetermined temperature. <P>COPYRIGHT: (C)2011,JPO&INPIT |
