PCT No. PCT/JP98/05993 Sec. 371 Date Sep. 9, 1999 Sec. 102(e) Date Sep. 9, 1999 PCT Filed Dec. 28, 1998 PCT Pub. No. WO99/36182 PCT Pub. Date Jul. 22, 1999By provision of paint cartridges of different colors which are detachably mounted on a coating system, the paint can be changed from one color to another in a multi-color coating operation without necessitating to discharge residues of a previous color. The paint cartridge of each color is replaceably mounted on a housing. Each cartridge is provided with a paint valve (46) which functions to communicate and shut off a paint supply passage in a feed tube. In addition, a thinner valve which serves to communicate and shut off a thinner passage on the housing is provided either on the side of the housing or on the side of the cartridge. These arrangements make it possible to cope with multiple color changes on one coating system. Since both of the paint valve and thinner valve are opened and closed by spray-on and spray-off command signals, respectively, the paint spray can be turned on and off immediately in response to these command signals.
