Title: ELECTROSTATIC SPRAY COATER
Abstract:
A current-detecting resistor (15) is connected between the output terminal of a high-voltage generator (14) and an air motor (3). Based on the potential difference (ΔV) generated between the two ends of the current-detecting resistor (15), a coater current detector (24) is provided to detect the coater current (IB) supplied to a coater (1). A high-voltage controller (22) determines whether the coater (1) is close to the object (A) to be coated based on the coater current (IB) detected by the coater current detector (24). The high-voltage controller (22) outputs a cut-off signal for cutting off the supply of the power supply voltage for a power source voltage controller (17) when the coater (1) is determined to be close to the object (A) to be coated.
