Patent ID: 7069648

Claim:
A component mounting method comprising: moving in first and second orthogonal directions a first mounting head section having first nozzles, rotating said first mounting head section such that said first nozzles rotate, and successively picking up components from a first component supply table arranged on one side of a board transfer path, with said first direction being perpendicular to said board transfer path and said second direction extending along said board transfer path; then successively mounting onto a board, positioned in said board transfer path, the components picked up by said first nozzles; moving in third and fourth orthogonal directions a second mounting head section having second nozzles, rotating said second mounting head section such that said second nozzles rotate, and successively picking up components from a second component supply table arranged on an opposite side of said board transfer path, with said third direction being parallel to said first direction and said fourth direction being parallel to said second direction; then successively mounting onto said board, positioned in said board transfer path, the components picked up by said second nozzles.
