<P>PROBLEM TO BE SOLVED: To provide an automatic door device capable of promoting convenience. <P>SOLUTION: The automatic door device 12 outputs a request signal to a predetermined area around a door from a locking and unlocking control section 21. When a portable machine 11 receives the request signal, an ID code signal is transmitted. When the locking and unlocking control section 21 receives an ID code signal, a door driving mechanism provided to a door closer 10 is driven from a door control section 31 to automatically open the door at a predetermined extent of opening. When an operating switch 16 of the portable machine 11 is operated, a locking and unlocking operation signal including an unlocking operation code is transmitted from the portable machine 11. When the automatic door device 12 receives the locking and unlocking operation signal, the door driving mechanism is driven from the door control section 31 to automatically open at an extent of opening more than the extent of opening based on the ID code signal. <P>COPYRIGHT: (C)2004,JPO |
