When a voltage difference diff of a vertex (maximum value) of a standard Position Resolving Table (PRT) is Dps, the voltage difference diff of a vertex (maximum value) of a tilted PRT is Dp, an amount of shift of the vertex in a horizontal direction is DeltaS, and a half of a coil placement pitch is Ls/2, a ratio of Dps to Dp (Gain) is equal to Dps/Dp (Gain=Dps/Dp). A value showing a proportion of a displacement of the vertex of the titled PRT with respect to the vertex of the standard PRT and the range of Ls/2 (Slide) is equal to DeltaS/(Ls/2). Therefore, a positional error due to a tilt of a stylus or a change in a battery voltage can be corrected.
