Abstract
A work direction determining device includes a passive tag type IC tag secured at a predetermined position on the front surface thereof. The IC tag includes a substrate, an IC module and an antenna coil disposed on the substrate in an offset manner. The device includes an antenna communicating with the IC tag, and a determination circuit. Where the work and the direction determining device are located at respective predetermined communication positions, communication is done between the antenna of the direction determining device and the antenna coil of the IC tag, and the magnitude of communication intensity during the communication is determined by the determination circuit to thereby determine a direction of the work.
