[0002]

2. Description of the Related Art A conventional container terminal is of a type in which containers are directly stacked and stored on a container yard. When shipping containers stacked in this way, there is no problem if they are shipped sequentially from the top one, but if you want to ship the containers stacked at the bottom first, separate the containers stacked above it. Must be transported to the place where the cargo is to be shipped, which is troublesome, and the smoothness of the cargo handling work is impaired. In order to solve such a problem, it has been studied to arrange container storage shelves for storing containers one by one in a multi-stage and multi-row manner so that containers can be taken out from any shelf when shipping.
