When a fire breaks out in a high-stored building, smoke including strong toxic gases is produced as things are burning and the smoke rises vertically in the building in a short time. An emergency exit is installed in a building for the preparation of a fire and an entrance door installed at the emergency exit should be always open in preparation for a fire. However, due to security and theft reasons of offices occupying the building, the entrance door is usually shut and further locked or blocked by a locking apparatus since the place may be used for a crime or juvenile delinquency. As the emergency exit is closed, when a fire breaks out, people are surprised and frightened, and sometimes go frantic and irrational, so that they are suffocated by smoke and jump from the high place, resulting in loss of valuable lives. The entrance door of an emergency exit during a fire in a building is opened manually. However, a rapid reaction to the occurrence of a fire in a building is not easy. Furthermore, since an electric power switch is turned off at the initial stage to prevent propagation of a fire, an entrance door of an emergency exit which can be open by an automatic operation cannot be open.
