SIMPLE CONSTANT TEMPERATURE DEVICE FOR ELECTRONIC DEVICE AND METHOD FOR CONTROLLING THE CONSTANT TEMPERATURE DEVICE

摘要

The invention relates to a simplified thermostatic apparatus for an electronic apparatus and its control method achieving thermostatic formation of an electronic apparatus and constituting an object by preventing a deterioration in accuracy by a change in a surrounding temperature, and a highly heat-insulating vessel (1) provided with a radiator (2) capable of making a heat resistance variable is provided with a fan (4) for circulating a gas at inside of the vessel (1), temperature detecting means (7) for detecting a temperature at inside of the vessel (1) and heat resistance controlling means (3) for controlling the heat resistance of the radiator ( 2) in accordance with an output of the temperature detecting means (7). <IMAGE>
