- 1115 is a current detection resistor.
- each end of the strip-shaped resistor on the tablet 1101 is provided with an unused portion that does not allow a finger to approach. The reason is that if a finger touches a part near the end of the strip-shaped resistor, the time constant formed by the capacitance of the contact portion between the strip-shaped resistor and the finger becomes small, resulting in a measurement error. This is to avoid this.

- Ri i is obtained, and then R 2i is obtained from equation (2).
- the position of the finger in the y-axis direction is obtained from the relationship of Expression (3).
- the flat part of the current I ai actually observed corresponds sufficiently to the ⁇ ⁇ part of the frequency of the transient response.
- the exact position of y is the position where the capacitance due to the contact surface between the finger and the strip-shaped resistor exceeds a certain value (the position where the time constant is satisfied, that is, the length of the strip of the strip-shaped resistor contact surface from the upstream side). Does not indicate the center of the tt part of the finger. This is further illustrated in FIG. Therefore, for example, when the finger is pressed strongly, y fluctuates, and the time constant changes depending on the position of the finger in the y-axis direction. Therefore, the constant value p itself is also a function of y. Therefore, after calculating the outline position of the finger on the upstream side of the strip to calculate the actual center position of the finger, the center is calculated, and the X-axis data, etc., assuming that the finger contact surface is circular It is necessary to perform correction processing using
