Claim 10:
11. A control method for a position detection sensor which is used for a position detection device, the control method comprising:
providing a main body with a housing that encloses an electronic pen while the electronic pen is accommodated in an accommodation portion included in the housing; and
providing a planar coil having a rectangular cross-sectional area adjacent to the accommodation portion at a position at which a direction perpendicular to the rectangular cross-sectional area of the planar coil crosses an axial direction of the electronic pen while the electronic pen is accommodated in the accommodation portion,
wherein the electronic pen has a position indication coil wound in the axial direction of the electronic pen,
wherein the planar coil includes at least a first side and a second side that is shorter than the first side,
wherein, while the electronic pen is accommodated in the accommodation portion, the first side of the planar coil extends substantially in parallel to the axial direction of the electronic pen, and
wherein the planar coil is positioned with respect to the accommodation portion such that, while the electronic pen is accommodated in the accommodation portion, a magnetic flux generated in the planar coil is displaced with respect to a position of the position indication coil.
