Abstract: PURPOSE:To obtain an output voltage free from effect of a power source voltage without using a stabilizing power source by providing a division section for dividing an output voltage of a detecting part by the power source voltage to detect the position from an output of the division section. CONSTITUTION:A square wave and a triangle wave are generated synchronizing each other from an oscillation part 1 and the square wave is inputted into a detecting section 2 to excite coils 8 and 9 at the detecting section 2. Here, if the power source voltage Vs increases, the output of the detecting section 2 increases in proportion to an increasing rate at the power source voltage Vs. An output of the detecting section is inputted into a division section 3 as pullup voltage. On the other hand, the triangle wave generated at a transmitting section 1 is inputted directly into the division section 3 and modulated in pulse width with a comparator 5 to output the square wave with a pulse width proportional adversely to the increase in the power source voltage. In addition, an output of the comparator 5 is made to overlap the output of the detecting section 2, thereby achieving the modulation in pulse amplitude simultaneously and an output obtained is applied to an integrator 6 to be an output of the division section 3.
