Abstract

PURPOSE: To ensure the detection of a dewed condition by operating a heating means when a dewed condition is detected, and by judging the non-dewed condition when the dewed condition is continuously detected after a fixed period of time has passed since the operation of the heating means.
CONSTITUTION: A dewing detection device is provided with an inter-electrode gap dewing sensor A for which a pair of thin film electrodes are arranged at a very small interval on a substrate, and a dewing judgement means B for detecting a dewing condition from the reduction in the resistance value between both electrodes of the dewing sensor A. In this structure, a heating means C, which approaches the dewing sensor A, and by which the substrate between both electrodes is heated, is provided. When a dewing condition is detected by the dewing judgement means B, the heating means C is worked, while, when the dewing condition is continuously detected by the dewing judgement means B after a fixed period of time has passed since the operation of the heating means, the state of non-dewing is judged by a non-dewing judgement means D. A non-dewing condition is thus judged, while the dewing condition is detected in an accurate manner.
