PURPOSE:To provide the titled apparatus having a wide change range of a coating pattern and improved in a paint atomizing property, constituted so as to increase and decrease atomizing air within a range of a necessary smallest amount or more by providing a pattern regulating apparatus to an atomizing air supply line. CONSTITUTION:In a paint spraying apparatus equipped with a paint supply line 2 communicated with a paint injection port 1 provided with a needle valve 13 operated by an air cylinder/piston apparatus 17, an atomizing air supply line 4 communicated with an atomizing air injecting port 3 for injecting air for atomizing an injected paint and branched from a common air supply line 7 and a pattern air supply line 6 communicated with a pattern air injecting port 5 for injecting air for controlling the injection shape of a stream mixture of the paint and atomizing air and branched from the above-mentioned common air supply line 7, a pattern regulating apparatus consisting of a valve 14 provided with a bypass line 16 for passing a necessary min. amount of atomizing air and a regulating screw 15 is provided to the above-mentioned atomizing air supply line 4 and the amount of atomizing air is increased and decreased to perform the regulation of a pattern.
