A temporary storage device transfers an article in different positions to and from an overhead travelling vehicle system and a second transport system, and transfers an article to and from an article transfer position outside the temporary storage device. The temporary storage device includes a local carrier including a hoist, travel rails of the local carrier below a travel rail of the overhead travelling vehicle system, passing directly above an article transfer position, and a slide rack below the travel rails of the local carrier, slidable between a portion directly above the transfer position and a second position in which an article can be transferred to and from the second transport system, the second position being different from the portion directly above the transfer position in a direction perpendicular or substantially perpendicular to the travel rails of the local carrier in a horizontal plane.
