PURPOSE:To reduce the number of persons required for setting a printed circuit board (PCB) to a conveying pallet and their labor and time thereof, by conveying the PCB with a conveyor directly without using the conveying pallet. CONSTITUTION:Each printed circuit board 10 is conveyed by a conveyor 11. And, it is stopped at a position of a stopper 12, but when a leading-in device 13 comes to a position continuing to the conveyor 11, its stoppage by the stopper 12 is released, thus this PCB 10 is transferred to the leading-in device 13. If so, the leading-in device 13 moves in a direction of an arrow E whereby the PCB 10 is transferred to a buffer conveyor 15, therefore it comes to a printed circuit board 14 for a buffer stock. One sheet of the forefront of this PCB 14 arrives at a working spot, and is made to go up with a lifter 16 whereby circuit inspection or operation of parts insertion, etc., takes place. When this operation is over, the PCB 14 is transferred onto a leading-in device 17 and moved in a direction of an arrow F, thus it is taken out by the conveyor 11.
