A current detection resistor (15) is connected between the output terminal of a high voltage generator (14) and an air motor (3). A coater current detector (24) for detecting a coater current (IB) supplied to a coater (1) based on a potential difference (”V) taking place on the both terminals of the current detection resistor (15) is provided. The high-voltage control device (22) serves to discriminate based on the coater current (IB) detected by the coater current detector (24) whether the coater (1) is caused to be close to a coating object (A). When it is discriminated that the coater (1) is caused to be close to the coating object (A), the high-voltage control device (22) outputs a shut-off signal for shutting off supply of the power supply voltage to the power supply voltage control device (17). |
