PURPOSE: An electronic component mounting apparatus is provided to accurately output nozzle position information, an angular reference, the actual rotation center of a nozzle head, and optical magnification of a camera by installing two or more identifying indicators on the nozzle head of each nozzle unit. CONSTITUTION: A nozzle unit(12) is changeably installed using a joint block. The nozzle unit comprises a joint plate(29) and an arm unit(30) fixed to the joint plate. The nozzle unit comprises a shaft(31) installed on the arm unit, a rotary type nozzle head(20) rotating with a rotation center shaft as a rotation axis, and a drive unit(33) which rotates the nozzle head with respect to the shaft. The nozzle head comprises the shaft, an armored bearing(34), and a nozzle casing(35). A driving gear(41) is fixed to the nozzle casing in order to surround the shaft. A pinion(42) is geared with the driving gear.
