The internal sensor switch and the external sensor switch set a predetermined time from when the door is opened until a person passes through the entrance. During this set time, the door is kept open and the set time has elapsed. Then the door is closed.

When an object such as a person is detected by either the internal sensor switch or the external sensor switch, an object detection signal is input from the internal sensor switch or the external sensor switch to the control calculation unit of the door controller to open the door. The opened door is closed when an object such as a person is no longer detected by either the internal sensor switch or the external sensor switch. However, even if an object such as a person is no longer detected by either the internal sensor switch or the external sensor switch, an object such as a person may be passing through the door. In such a case, the door of the automatic door is opened. There is a case where a person is caught by a door between the time it passes and the time when the person passes through the entrance.
Therefore, if a person stops at the entrance, the door closes after the set time has elapsed, the door closes, and the person may be caught in the door. Conventionally, the automatic door device is provided with a safety light switch so that the door is not caught by the door until it passes through the entrance.

In this way, the safety light switch continues the door in an open state as long as an object such as a person passing through the door is detected.
