<p>A projection display device, i.e., one example of electronic devices, is provided with a case (1), a plurality of temperature sensors (4A-4C), a reference temperature sensor (5), a projection section (6), a plurality of louvers (7A-7C), an adjusting section (8), a suction fan (10), and an air-release fan (12). The adjusting section judges whether each temperature difference between a temperature detected by each temperature sensor and a temperature detected by the reference temperature sensor is within a normal range, and adjusts angles of a plurality of louvers so as to increase the quantity of air flowing close to the temperature sensor which has indicated the temperature difference not within the normal range. Thus, local temperature increase in a case of the electronic device can be relaxed.</p> |
