Work direction determining method and device, and work provided with direction determining function
First Claim
1. A work provided with a direction determining function, communicating with a direction determining device at a predetermined communication position and determined by the direction determining device as to whether to assume a normal posture or a reverse posture,wherein the direction determining device includes an antenna communicating with an IC tag, and a determination circuit determining the magnitude of communication intensity during the communication;
- wherein the IC tag capable of communicating with the direction determining device is secured to an upper surface of the work at a predetermined position;
wherein the IC tag is configured as a passive tag type including a substrate, an IC module and an antenna coil, the IC module and the antenna coil being disposed on the substrate adjacent to each other;
wherein the antenna coil is disposed on the substrate in an offset manner so that a communication distance between the antenna coil and a communicable zone of the antenna of the direction determining device is different in magnitude on the basis of a difference in the posture of the work at the predetermined communication position;
wherein the work is shaped as a rectangular parallelepiped and is provided with two compartments;
wherein respective mouths of the two compartments are opened in an upper surface of the work at anteroposteriorly symmetrical positions and the IC tag is disposed between the mouths; and
wherein the antenna coil is disposed in an offset manner on one of front and rear sides of the substrate constituting the IC tag, and the IC module is disposed on the other side.

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.
