摘要

PROBLEM TO BE SOLVED: To improve an interface by increasing the number of available packs for detecting a rotational angle of≤180 degrees.

SOLUTION: In the pack device, two coils A and B having the same resonance frequency and different diameters are mounted, and the mounting positions for the respective coils A and B are positioned on a line connecting the centers of the respective coils together. The sense table device is constructed of a signal receipt part for receiving respective signals induced from the two coils, which are mounted in each pack device and provided with the equal resonance frequency and different diameters, by electromagnetic induction and a computing part for computing the center and the rotational angle of each moving pack device according to the respective signals obtained from each pack device.
