えていることを特徴とする自動ドア用安全装置。 A safety device that detects the approach of an object to an automatic door using a sensor with a certain detection range and controls the opening and closing of the door. In addition, a safety detection range is set between the opening/closing detection ranges, and a safety detection range is set between the opening/closing detection ranges and the door travel path, which opens the door when an object is detected. A safety device for an automatic door, comprising a detection control mechanism that enables object detection in a safety detection range only while an object is being detected in any of the safety detection ranges.
