A main controller 50 controls carry in operations and carry out operations of articles to or from an article storage rack 1 using article transport devices 2 by causing a control command to be transmitted from a first optical communication device 10 that is associated with each article transport device 2 to a second optical communication device 20 provided to each article transport device 2. The main controller 50 is configured to perform a temporally-divided light-emission control in which a plurality of the first optical communication devices 10 are caused to emit light in a temporally divided manner such that there is only one first optical communication device 10 that emits light in any one time period among the first optical communication devices 10 that are located close to one another in the vertical direction.
