PURPOSE:To facilitate the operation for continuously carrying loads by enabling to register respective designation calls to two floors to a call registering means, and repeatedly operating a cage between the two registered floors. CONSTITUTION:The soft wear of a microcomputer control unit 51 is roughly divided into an actual operation control means 83 and a call registering means 88. To enable the repeated reciprocation of a cage between two floors, the call registering means 88 made possible to register respective designation calls to two floors is used, and the designation calls are successively outputted from the call registering means 88 to the actual operation control means 83 for driving the driving device of a dumb waiter and raising/lowering the cage through a raising/lowering direction selecting circuit for selecting the raising/lowering direction to be actually operated. When loads are continuously carried, thus, the same operation as the first time is not required, the operation can be simplified, and a wasteful operation can be eliminated. |
