PURPOSE:To prevent the number of produced printed-circuit boards from being reduced even when types are changed over frequently in an arrangement due to the changeover of the types in a component-mounting apparatus in which an electronic component is mounted or in a system apparatus in individual processes other that it. CONSTITUTION:Detectors 12, 9, 15 which detect the arrival of a printed-circuit board 6 are installed at a loader part 7, an X-Y table 8 and an unloader part 14 for an electronic-component mounting machine. The individual conveyance parts 7, 8, 14 are used as one rearrangement unit. When the individual detectors 12, 9, 15 detect the printed-circuit board 6, a conveyance passage 13 in a previous stage, the loader part 7 and the X-Y fable 8 are brought closer. When the individual conveyance parts 7, 8, 14 are brought closer by using them as a minimum unit, the loss of the changeover time of a rearrangement can be reduced. |
