According to the first aspect of the present invention, when the apparatus is separated from the preceding article by a predetermined distance or more, the apparatus is driven at a constant speed and separated from the preceding article by a predetermined distance or more. If it is not, it stops, and when transporting the goods at regular intervals, it is added again during the deceleration from the constant speed to the stop.
If Hayashi returns to a constant speed, when the constant speed this again accelerated, and maintained a middle speed during deceleration to a stop a predetermined time by accelerating again, the time to start the acceleration Since the distance can be made equal to the normal case, the distance between the conveyed objects can be maintained as in the case of accelerating after stopping, and the distance between the conveyed objects can be accurately made constant.
