• a transportation mechanism that is movable in a direction in which the cartridges are inserted and in a direction in which the cartridges are removed, the transportation mechanism including
• a removal mechanism that selectively removes one of the cartridges stored in the magazine having been loaded, and
• a connection member, to be connected to the magazine inserted through the magazine loading opening;
• and
• a controller that controls the transportation mechanism,
• wherein the transportation mechanism transports the removed cartridge to a cartridge processing unit provided in the library apparatus, the removed cartridge having been removed using the removal mechanism,
• wherein the controller controls the transportation mechanism such that the transportation mechanism stands by on the magazine loading opening side when the magazine is not loaded, and controls the transportation mechanism such that the transportation mechanism pulls the magazine to the loading completion position when the controller detects that the magazine is inserted through the magazine loading opening and the connection member is connected to the magazine.
