PROBLEM TO BE SOLVED: To provide a board conveyance device and a board conveyance method in an electronic part mounting line by which the board can be conveyed according to production form and the productivity be also improved. SOLUTION: This board conveyance device is used to convey a board 1 from the upstream side to downstream side in an electronic part mounting line where electronic part mounting devices are arranged in series. Bypass conveyor units BC1 and BC2 respectively provided with upper- and lower-stage conveyors for respectively conveying not-mounted boards and mounted boards specially are arranged above electronic part mounting devices M1 and M2, and a lifter conveyor L2 is provided to distribute the boards 1 to the electronic part mounting devices M1 and M2 and to the bypass conveyor units BC1 and BC2, respectively. Thus, the board 1 can be carried in/out in one electronic part mounting device regardless of the operation state of the other electronic part mounting devices, and it is conveyed corresponding to the production form selected in accordance with the kind of board, resulting in improving the productivity. |
