<P>PROBLEM TO BE SOLVED: To provide an automatic door that prevents injury to the human body or damage to an object and a door by decreasing an impact force when the door collides with a person or the object existing on the door case side of the automatic door. <P>SOLUTION: A door case sensor 5 for detecting a person or an object existing on the door case side 20 of an automatic door is provided. When a detection signal of the door case sensor 5 is input into a controller 3, the controller 3 controls opening drive of a motor 2 at a speed lower than a high opening/closing speed in a normal case, makes a door 1 move for opening at a low speed, and decreases an impact force at the collision of the door with the person or the object, so as to prevent injury to the human body or damage to the object and the door. <P>COPYRIGHT: (C)2012,JPO&INPIT |
