PROBLEM TO BE SOLVED: To facilitate change of arrangement for change-over of a type by stopping a driving motor when a printed wiring board detection sensor stops detecting a printed wiring board, reversing the driving motor at low speed thereafter, detecting the printed wiring board again by the printed wiring board detection sensor and stopping the driving motor and simultaneously locking the printed wiring board. SOLUTION: A following stand-by printed wiring board 5 is conveyed at high speed by driving a timing belt 4 for conveyance by a driving motor 2, and this following stand-by printed wiring board 5 is guided to a positioning part as a printed wiring board 8 for working. This printed wiring board 8 for working is continuously conveyed even after it is detected by a printed wiring board detection sensor 10 for working, and when the printed wiring board detection sensor 10 for working stops detecting the printed wiring board 8 for working, the driving motor 2 stops. Thereafter, the driving motor 2 reverses at low speed, simultaneously when the printed wiring board detection sensor 10 for working detects the printed wiring board 8 for working, the driving motor 2 stops, a printed wiring board fixing mechanism 9 locks the printed wiring board 8 for working and finishes positioning. |
