PURPOSE:To continue transportation processing on the basis of a transportation request even if an electric power source is disconnected from the time when an operator issues the transportation request until the time when the transportation request is actually given to a main control part by informing the main control part concerned for waiting transportation by means of a station control part with the aid of the state of a transportation waiting flag at the time of power restoration. CONSTITUTION:The station control part 3a waits the re-depression of a transportation request key. When an operator mounts commodities on a carrier, the transportation request key is again depressed. When the station control part 3a detects this redepression, it sets a flag to its transportation waiting flag 30a. With the power restoration after an electric power source is interrupted, the station control part 3a checks contents of said flag 30a. Where the transportation waiting flag 30a is set, said control part 3a views outputs of a lift sensor L1 and a stater sensor DS1 to check whether or not a carrier is in its station WS1. When the carrier is decided to be in it, the station control part 3a informs a linear motor controller 2 of transportation waiting with respect to poling from the controller 2. |
