Door system

A door system comprising:

• a compartment of a rectangular shape in plan view having a longer side in a direction orthogonal to a passing direction of passersby, the compartment being formed with a plurality of pairs of first gateway and second gateway with each pair of first gateway and second gateway being opposed to each other in the passing direction of passersby;
• and
• a barrier apparatus including:
• a plurality of swivel panels each of which swings back and forth within a predetermined angular displacement;
• a pair of door panels provided at opposite ends of each swivel panel, the pair of door panels operatively opening and closing the first gateway and the second gateway respectively at the same timing while keeping contact with an inner surface of the compartment;
• and
• a driving mechanism which synchronously swings the swivel panels back and forth in such a manner that the door panels on the side of the first gateways swing toward and away from each other and the corresponding door panels on the side of the second gateways swing toward and away from each other alternately.
