PROBLEM TO BE SOLVED: To improve working efficiency while inhibiting the apparatus costs of a pair circuit board working machine. SOLUTION: A wiring board carry-in confirmation sensor 150 is provided at the upstream end of a wiring board conveyor 18 of a plurality of side-by-side electronic component-fitting machines 2 for composing an electronic component- fitting line. A printed-wiring board is passed from a wiring board conveyor 18 at the upstream side electronic component-fitting machine 2 to the downstream side electronic component-fitting machine 2, and the wiring board carry-in conformation sensor 150 detects the carry-in of the printed-wiring board when the printed-wiring board passes the upper section of the wiring board carry-in confirmation sensor 150. According to the detection, a control apparatus allows the fitting apparatus to perform preceding operation to be executed before a printed-wiring board 20 arrives at a component-fitting position. The preceding operation includes an operation where a CCD camera for imaging the reference mark of the printed-wiring board moves to the imaging position of the reference mark, an operation where a component retention head receives electronic components to be fitted first from the component-supplying apparatus, and the like. |
