Claims

[Claims for Utility Model Registration] A first position provided on one of the door or the main body and close to the other of the door or the main body, and a second position farther from the other than the first position. a moving member that is movable with respect to the moving member; an opening member that is movable within a certain distance with respect to the moving member; and the opening member is moved in a direction away from the moving member and in contact with the other to open the door. a spring member that biases the moving member in an opening direction; and a spring member that moves the movable member to the first position and the opening member where the opening member abuts the other door due to the biasing force of the spring member and opens the door. drive means for moving the door across the second position to prevent the door from opening due to contact with the other; when the moving member moves from the first position to the second position, the moving member A holding means that locks on the opening member to hold the opening member in a predetermined position or release the holding, and a control means that controls the driving means and the holding means, and the control means is configured to control the door. In the closed state, the movable member is held at the first position, and the opening member is held at the predetermined position by the holding means against the biasing force of the spring member. After a predetermined time has elapsed since the operation, the holding by the holding means is released and the door is opened by allowing movement of the opening member by the urging force;
The automatic door is characterized in that the moving member is moved from the first position to the second position after the door is opened, and returned to the first position again after the door is closed. Opening mechanism.
