Abstract:
1. A coating apparatus that conducts electrostatic coating by supplying liquid coating to a rotary atomization head as the rotary atomization head is rotated, applying a high voltage thereto and thereby charging and atomizing liquid coating liquid coating and then spraying the liquid coating from the rotary atomization head, comprising; a body part; a head part detachably installed to the body part; a connection part connecting the body part with the head part, wherein the body part is provided with a cascade that boosts and outputs electric power and a plurality of first channels in which at least one of an optical signal representing the revolutions of the rotary atomization head, air, and coating circulates, the head part is provided with the rotary atomization head, an electric power transmission line that transmits electric power output from the cascade, and a second channel, on a connecting face of the body part, at least part of the cascade projects, and an end face of the first channel is exposed, and on a connecting face of the head part, the electric power transmission line is connected, and an insertion part in which a projected part of the cascade is inserted is formed, and an end face of the second channel connected to the end face of the first channel is exposed.
