<P>PROBLEM TO BE SOLVED: To provide a temperature-sensitive display device capable of improving serviceability by increasing types of information items to be displayed according to the temperature without increasing a displacement magnitude and drive energy required for a temperature-sensitive drive mechanism. <P>SOLUTION: The temperature-sensitive display device includes: rotational display means 10 that includes a first display surface 11 adapted to be displayed when it reaches a first temperature by a temperature increase, a second display surface 12 adapted to be displayed when it reaches a second temperature that is lower than the first temperature by a temperature fall, and a third display surface 13 adapted to be displayed when it reaches a third temperature that is higher than the first temperature by the temperature rise; and the temperature-sensitive drive mechanism that includes first shape-memory alloys 35 and 36 involving a switching display between the first display surface 11 and the second display surface 12, and second shape-memory alloys 135 and 136 involving a switching display between the first display surface 11 and the third display surface 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
