<P>PROBLEM TO BE SOLVED: To provide an apparatus for opening/closing a door automatically, which allows an electric lock to be surely fasten when the door is closed. <P>SOLUTION: This apparatus for opening/closing the door automatically is equipped with a telescopic arm which is composed of: a cylindrical body in which an electric motor is housed; and a coupling rod which is fitted into the side of one end of the cylindrical body, and pushed out from or pulled into the cylindrical body by operations of the electric motor. In the apparatus, the drive of the drive motor makes the telescopic arm extended/contracted, so that the door can be opened/closed. The door is equipped with the electric lock which has a closing sensor for detecting the turning of the door to a lockable position and can also be fastened/released by a prescribed key. The apparatus is equipped with a control part which starts the electric motor's drive for opening the door when a door opening command signal is input, stops the drive of the electric motor at the input of the door opening detection signal from a door opening sensor for detecting the turning of the door to a prescribed opened position, starts the electric motor's drive for closing the door, when the door opening command signal is input, and stops the drive of the electric motor at the input of a door closing detection signal from the closing sensor of the electric lock. <P>COPYRIGHT: (C)2003,JPO |
