<P>PROBLEM TO BE SOLVED: To provide a board working device and electronic component mounting device that improve production efficiency of a printed-circuit board and conduce to facility investment. <P>SOLUTION: After a large board P is passed from a supply conveyor 3 to positioning units 4 and 4, the positioning units 4 and 4 having received the large board move into a mounting area SA, where the mounting device 2 mounts electronic components on the large board P. Then an upstream conveying conveyor 6 standing by on the side of the supply conveyor 3 and a downstream conveying conveyor 7 standing by on the side of a discharge conveyor 5 are connected to the supply conveyor 3 and discharge conveyor 5, and a following large board P is reloaded from the supply conveyor 3 to the upstream conveying conveyor 6 and discharge conveyor 5; while electronic components are mounted on the precedent large board P on the positioning units 4 and 4 having moved into the loading area SA, the following large board P is reloaded from the upstream conveying conveyor 6 and discharge conveyor to the discharge conveyor 5 so that the following large board P gets ahead of the precedent large board P. <P>COPYRIGHT: (C)2009,JPO&INPIT |
