Abstract
An in-line coating device includes: a coating section configured to perform coating on a workpiece; and a transport section configured to transport a plurality of the workpieces in the coating section. The coating section is provided with a plurality of coating materials which are aligned. The transport section transports the workpieces such that the workpieces face the plurality of coating materials. The in-line coating device includes a voltage applying section configured to, when the workpiece is transported and faces each coating material, apply to the workpiece, a bias voltage to attract particles emitted from the coating material toward the workpiece. The bias voltages applied to the workpiece by the voltage applying section when the workpiece faces one of the coating materials can be different from that applied when the workpiece faces another one of the coating material.
