PROBLEM TO BE SOLVED: To quickly perform processing when a load is shipped by a load transporting machine to be laterally moved in relation to respective stages and a rising and lowering stand in relation to a temporarily placing rack, so as to decrease a loss of time, by providing a multistage temporarily placing rack on one side of a housing rack unit provided with load housing parts on the upper, lower, right and left sides into a matrix shape. SOLUTION: When a command of storage is issued from a main controller, a controller for a rising and lowering stand performs movement control in which a load to be stored is received from a conveyor to the rising and lowering stand (S5) and raised and lowered to a temporarily placing rack having the specified stage into which the load is to be stored (S6) regardless of the load presence sensor information of the temporarily placing rack. Approximately simultaneously, a controller for a load transporting machine asynchronously and parallely performs control in which the load transporting machine is moved to the front of the specified temporarily placing rack (S10). The load is immediately transferred from the rising and lowering stand to the temporarily placing rack (S9) by the sensor information in which there is no load (S7:no) in the temporarily placing rack, on the other hand, the load is transferred from the temporarily placing rack to the load transporting machine (S13) by the sensor information in which there is a load (S11:yes) in the load temporarily placing rack.
