Abstract
A shield gate includes a door member disposed in a gap region located between an intra-area transport unit and an extra-area transport unit in a transport direction in a closed state in which the shield gate shields an opening, and is disposed at a position displaced from the gap region in an open state in which the shield gate opens the opening. A second interval is a length of the gap region that allows the door member to be disposed, during at least a part of a non-transport period, the length of the gap region is set to be greater than or equal to the second interval, and the shield gate is in the closed state, and, during the transport period, the shield gate is in the open state, and the length of the gap region is set to a first interval that is shorter than the second interval.
