PROBLEM TO BE SOLVED: To enhance the work efficiency of a circuit part feeding system where a part holder is replaced automatically. SOLUTION: An electronic part feeding system has a tray type feeder 18 and a tray containing box 202 contains a tray 236 for containing a plurality of electronic parts 32 and a tray 238 for containing a plurality of suction nozzles 274, 276 while stacking. The tray containing box 202 is moved up and down by an elevating unit 232 and a tray 236 is positioned at a draw-out position for feeding the electronic part 32 whereas the tray 238 is positioned thereat for replacing the suction nozzles 274, 276 before being drawn out to a feeding position by a draw out unit 250. After the electronic part 32 is sucked by shifting a part holding head 30 to the feeding position or the suction nozzles 274, 276 are replaced, the electronic part 32 is sucked and mounted on a printed board. |
