The opening/closing portion 11 has vertically arranged guide rails 14, 14 having a U-shaped cross section for guiding both ends of a roll-type shutter 13 in the width direction. The shutter 13 is slidable in the vertical direction without being detached from the guide rails 14, 14. When the shutter motor 15 is rotated in a predetermined direction, the shutter 13 located between the guide rails 14, 14 is wound up and the opening/closing portion 11 is opened. When the shutter motor 15 is rotated in a reverse direction, the shutter 13 is fed between the guide rails 14, 14 and the opening/closing portion 11 is closed. A controller 24 performs a predetermined guiding according to the approaching of the small-sized flying object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatic opening/closing door","description":"An automatic opening/closing door 10 has an opening/closing portion 11 located at a lower side and a storage portion 12 located at an upper side.
