Abstract
The present invention provides a swing door opening/closing detection system capable of accurately discriminating an opening/closing position of door main bodies to accordingly prevent the malfunction of the door main bodies. The swing door opening/closing detection system includes: door main bodieswhich are rotatably provided and which rotate to open/close relative to an opening part; driving partsrotary driving the door main bodies; a control partcontrolling the rotary driving of the door main bodiesby the driving parts; a sensing part() attached to the door main bodiesto sense a person or an object in sensing areas on paths of the door main bodies; a deformation partdeforming according to the rotational operation of the door main bodies; and a discriminating part() which discriminates the opening/closing position of the door main bodiesbased on a deformation amount of the deformation partto control the control partbased on the discrimination result.
