The article conveying facility of Patent Document 1 is provided with a load receiving platform on the left and right of the travel path of the stacker crane as viewed in the travel direction. Further, the input console is provided with a cradle selection button for selecting which of the left and right cradles should be loaded.
Further, in the article transport facility of Patent Document 1, an optical receiver that receives input information from an input console is provided only at one end side in the traveling direction of the stacker crane (hereinafter referred to as a home position and abbreviated as HP). Therefore, the input console is configured to be used only by HP. On the other hand, it may be desired to use the input console from the other end side of the travel path of the stacker crane (hereinafter referred to as an opposite position and abbreviated as OP) due to the situation of the travel path. In this case, it is conceivable to provide an optical transceiver on the OP side.
However, the input console is only supposed to be used on the HP side as described above, and the characters on the HP side such as “Right side” and “Left side” are used for the explanation display of the load receiving base selection button. Is displayed. For this reason, if the operator tries to use the same input console on the OP side, the operator will use the button labeled “Left” when unloading the load to the right-hand receiving platform, Must press the button labeled “Right” and the operator must enter the command information while considering the relationship between the button's explanation display and the direction that he / she actually wants to instruct. The burden increases.
