PROBLEM TO BE SOLVED: To place a pair of first and second opening/closing bodies in a smooth opening action along passage of a passing body while the inside and outside of a room in a building are partitioned off with the first and second opening/closing bodies stacked in inward/outward directions and a standby room is formed between the opening/closing bodies.SOLUTION: A standby room 1 is provided with first and second intermediate sensors 11, 12. In a both-opening/closing-body standby state in which first and second sheet bodies 3a, 4a are both fully open and passing bodies are expected to enter the standby room 1 from the room inside 2 and room outside OA, a sheet body 3a or 4a present ahead in an onward direction is opened on detection by at least one first and second intermediate sensor 11, 12, but not in the both-opening/closing-body standby state, the first opening/closing body 3a is opened on detection by the first intermediate sensor 11 and the second sheet body 4a is opened on detection by the second intermediate sensor 12. |
