- the position indicator the pressure (writing pressure) applied by the user is detected and transmitted to the position detection device, whereby information corresponding to the writing pressure of the user can be input.
- a variable capacitor described in Patent Document 1 is used to detect the writing pressure applied by the user in the position indicator.
- the core body 300 is displaced to the dielectric 101 side accordingly, so the second electrode 103 is curved and approaches the dielectric 101 side.
- the electric capacity of the air layer 600 increases in inverse proportion to its thickness, and the electric capacity between the first terminal 108 and the second terminal 109 increases.
- the capacitance between the first terminal 108 and the second terminal 109 becomes the dielectric. It increases in proportion to the contact area between the other surface 101 b of 101 and the second electrode 103. Therefore, by detecting a change in the electric capacity between the first terminal 108 and the second terminal 109, the pressure (writing pressure) applied to the pen tip connected to the core body 300 can be detected.
- the first electrode is attached to one surface (first surface) of the dielectric, and the second electrode is opposed to the other surface (second surface) side.
- the variable capacitor is configured by arranging and pressing the second electrode against the second surface of the dielectric by the core body according to the writing pressure.

In the variable capacitor 100 ⁇ / b> A, the first electrode 102 is attached to the first surface 101 a of the dielectric 101, and the first terminal 108 is connected to the first electrode 102. A linear second electrode 103 having a circular tip is attached to the second surface 101 b of the dielectric, and a second terminal is connected to the second electrode 103.

- the variable capacitor 100A of this example has an initial capacitance C0 because the second electrode 103 is already attached to the second surface 101b of the dielectric 101.
- variable capacitor 100A As shown in the pen pressure detection characteristic of FIG. 9B, the initial capacitance C0 is provided even when no pen pressure is applied, so that the brush can be applied by lightly applying force to the pen tip. The pressure can be detected. However, since the rise is improved by the function of the second electrode 103 attached to the second surface 101b of the dielectric 101, the range in which the pen pressure can be detected accurately is shown in FIG. 9B. The range is above the dotted line, and the resolution of the pen pressure is lowered.

The electric capacity changes between them, and the pen pressure can be detected accordingly.
- the electric capacity changes according to the contact area between the second surface 101b of the dielectric 101 and the conductive rubber portion 300b as the second electrode.
