Abstract
A measuring partmeasures the potential of a collecting electrodehaving collected positive and negative ions respectively generated by ion generating partsof ion generatorsandand ion generating partsof ion generatorsand. In the judgment of the presence or absence of ions, the ion generatorsandand the ion generatorsandare alternately turned ON/OFF. In ion judgment 1, ON/OFF is performed 6 times with a period of 10 seconds. In ion judgment 2, ON/OFF is performed 10 times with a period of 1 second. Then, when the difference (the amount of change) between the maximum value and the minimum value of the output voltage of the measuring partis greater than a given threshold value, the presence of ions is concluded respectively.
