초록 ▼

A printed circuit board, load-unload system which has a printed circuit board processing portion; a magazine stock portion where a plurality of magazines, each of which houses a plurality of printed circuit boards, is arranged on a conveyor route; and a load-unload portion where one of the plurality of printed circuit boards is transferred between one of the plurality of the magazines in the magazine stock portion and the printed circuit board processing portion. The conveyor route of the stock portion includes a bypass route which bypasses the load-unload portion.
