<p>PROBLEM TO BE SOLVED: To apply different magnetic flux to a magnetic flux detection panel corresponding to various using states concerning a magnetic flux generating pen showing its own position on the magnetic flux detection panel. SOLUTION: Inside an outer cylinder 1, end parts 7d of a pair of permeable bodies 7 are fixed on a pair of magnetic poles of a magnet 6. The magnet 6 is energized toward an axial bottom by a spring 5 provided in the gap with a bottom part 1c. Besides, rollers 44 and 45 are provided between a pair of permeable bodies 7 and a cylindrical part 1b of the outer cylinder 1 and by operating a positioning pin 81 provided on the magnet 6, the magnet 6 and the permeable bodies 7 can be integrally moved toward the axial head and the axial bottom. Head parts 7a of a pair of permeable bodies 7 face orthogonally to the axial head through a gap member 7b.</p> |
