<P>PROBLEM TO BE SOLVED: To naturally operate deceleration down to stop of the partition bodies by using an obstacle detection means controlling drive of the partition bodies by detecting an obstacle frontwards of a rotary direction of the partition bodies in a revolving door device. <P>SOLUTION: The first, the second and the third detection ranges A, B and C are set frontwards of the rotary direction of the partition body 3 by the obstacle detection means. The first, second and third sensors 11, 12 and 13 detect the obstacle in the detection ranges A, B and C. A control part 10 makes the first low speed control which sets the speed at a first low speed by an input from the third detection sensor 13, makes the second low speed control which sets the speed at a speed lower than the first low speed by an input from the second detection sensor 12, and makes stop control of the partition body 3 by an input of the first detection sensor 11. <P>COPYRIGHT: (C)2003,JPO |
