<P>PROBLEM TO BE SOLVED: To provide a security gate by forming a flap of a light material excellent in wetherability and impact resistance and by reducing a burden on a motor and a gear when a person crashes against the flap. <P>SOLUTION: A gate main body 10 includes at least two or more upper passing through detection sensor 12a detecting passing of a person; and a flap position sensor detecting a position of a flap 11. When the flap 11 is turned, the gate main body 10 determines whether or not the flap 11 is turned artificially, and if it is determined that the flap 11 is turned artificially, turns the flap 11 to close a coming in and leaving out passage W when the sensor 12a has not detected any person already. <P>COPYRIGHT: (C)2009,JPO&INPIT |
