Claim:
An electronic component mounting apparatus comprising: a plurality of component feeding units feeding electronic components to component pick-up positions; a suction nozzle picking up one of the electronic components from one of the component feeding units and mounting the picked up electronic component on a printed board; a line sensor unit detecting the electronic component picked up by the suction nozzle; a component recognition camera recognizing a position of the electronic component picked up by the suction nozzle; a mounting head housing the line sensor unit and the suction nozzle and configured to travel between the component pick-up positions and the printed board; and a selection device selecting the line sensor unit, the component recognition camera or both the line sensor unit and the component recognition camera so as to determine whether the electronic component picked by the suction nozzle is still held by the suction nozzle after an attempt to mount the electronic component on the printed board.
