In a conveyor system including a plurality of processing devices such as wire bonders that are lined-up and supplied with workpieces via a plurality of individually operated conveyors that are aligned linearly, when one (or more) processing device is ready to perform its processing such as bonding, a stopper installed in front of the processing device is raised to stop the conveyance of the workpiece, and when a sensor provided near the conveyor senses the conveyed workpiece, the conveyor is temporarily stopped and then rotated again for a fixed period of time or is slowed down in speed and then rotated for a fixed period of time or a fixed distance. Thus, a workpiece being conveyed is slowed down and therefore avoided from hitting the stopper at a high speed. Thus, the workpiece is prevented from being damaged at the front edge. Also, since the workpieces do not bounce back, they are stopped at the same stopping positions.
