Abstract: Provided is an electronic pen including an electronic pen main part including a first sealing member that covers circumference of a tip side of the electronic pen main part and a second sealing member disposed along an outer edge of the electronic pen main part at a position separate from a tip toward a rear end side of the electronic pen main part, and an inside body that is tubular and has an inner wall surface with which the first sealing member and the second sealing member come into contact through insertion of the tip side of the electronic pen main part into the inside body.

Abstract: A coating apparatus has a rotary atomizing head that discharges paint to a work, and an air injecting unit that injects annular shaping air towards an outer peripheral edge portion of the rotary atomizing head. The air injecting unit has first air injecting ports and second air injecting ports. First air of relatively high wind speed is injected from the first air injecting ports and second air of relatively low wind speed is injected from the second air injecting ports.

Abstract: An intermediate reserve tank for temporarily storing a conductive coating medium is provided in a coating medium supply passage for supplying the conductive coating medium from a color switch valve mechanism to a spray gun. A block valve mechanism for electrically insulating the color switch valve mechanism and the intermediate reserve tank is provided. A coating medium extrusion portion for supplying water or a cleaning solution is connected to a transmission passage between the intermediate reserve tank and the spray gun via a switch valve. When an amount of the coating medium necessary until an end of a coating operation becomes a predetermined amount, the conductive coating medium is extruded by the water or the cleaning solution by switching the switch valve.
