PROBLEM TO BE SOLVED: To reduce time for moving a component mounting position to a substrate by a head by adding a rotation component at a rotary part in addition to a traveling component at an XY table for moving a rotary part that is rotated around an axis center vertical to the mounting surface of the substrate for each retention part in XY directions. SOLUTION: A printed-circuit board 1 is retained by a retention part 2 in a substrate-moving device 6, the retention part 2 is arranged on a rotary part 3 and is rotated around a rotary axis center 5 that is vertical to the component mounting surface by the rotary part 3. The rotary axis center 5 is located at a fixed position when viewed from an area on the printed-circuit board 11. The rotary part 3 is arranged on the XY table 4, and the entire circuit 3 is configured so that it can travel in XY directions. When the printed-circuit board 1 is rotated around the rotary axis center 5, a next part-mounting position can be moved on a circumference 7 with the distance to the rotary axis center 5 as a rotary radius and can be moved to a point that is closest to the component mounting position immediately before on the circumference 7. |
