    • [Problem] To carry an article held by a carrier to be maintained and/or an article housed in a housing shelf in the isolation region to a housing shelf that is accessible to the remaining carrier and thus to allow the remaining carrier to transfer the article. [Solving Means] If a control device 200 receives an instruction to retreat a first carrier (a particular carrier) 101 and if the first carrier 101 is holding an article 400 or if an article 400 is housed in a housing shelf 50 corresponding to an isolation region (a first region 301) serving as a retreat destination, the control device 200 causes the first carrier 101 to carry the article 400 to a housing shelf 50 to and from which a second carrier (the remaining carrier) 102 is able to transfer an article, then causes the first carrier 101 to retreat, and then drives the second carrier 102 within a range of a track except for the isolation region. When it is detected that one of first open/close doors (open/close doors) 31A to 33A corresponding to the isolation region has been opened, the control device 200 continues driving the second carrier 102.
