PURPOSE: A nozzle driving unit of a component mounting system is provided to perform easily a mending work and reduce a phase difference between rotation directions of nozzles by using only one driving motor to simplify a structure of the nozzle driving unit. CONSTITUTION: A nozzle driving unit of a component mounting system includes a plurality of rotary plates(35), a plurality of driving pulleys(31), a plurality of driven pulleys(32), and a connection member(36). The rotary plates(35) are installed at a rotary shaft of a driving motor. A plurality of first coupling projection shafts(35a) are formed at the rotary plates. Each driving pulley(31) is arranged in a line on each side of the rotary plates. A plurality of second coupling projection shafts(31a) are formed at the driving pulleys(31), respectively. The driven pulleys(32) are installed in parallel to the driving pulleys. A plurality of nozzles(41) are installed at each center of the driven pulleys. The driven pulleys are connected to the driving pulleys by using a belt(33). The connection member(36) includes a plurality of coupling holes into which the first and the second coupling projection shafts(35a,31a) are inserted.
