<P>PROBLEM TO BE SOLVED: To provide an installed object information management system, an installed object marking tool, a reader/writer, and an installed object information management method which are capable of easily recognizing an extension direction of an installed object without specially using a device only for detecting the extension direction of the installed object. <P>SOLUTION: An installed object marking tool 1 has an indication mark 10 which indicates an installation position of the installed object relative to the installed object marking tool and designates a direction on a plane of a reader/writer 4 relative to the installed object marking tool. A wireless IC tag 3 has an information storage part in which direction information indicating an extension direction of the installed object from a reference point Pi is stored as one piece of management information, where the reference point Pi is an intersection between a virtual extension line Lv in the direction indicated by the indication mark of the installed object marking tool and the installed object. The reader/writer displays a direction icon visually indicating the extension direction of the installed object from the reference point in a state where the reader/writer is aligned with the designated direction, on a liquid crystal display part 20 on the basis of direction information out of the management information received from the wireless IC tag. <P>COPYRIGHT: (C)2012,JPO&INPIT |
