Patent ID: 7242340

Claim:
An input device comprising: a first resistor and a second resistor each having an equal size and shape extending in one direction and arranged in parallel to each other and each having a constant and equal resistance per unit length in longitudinal direction thereof; and a processing unit configured to detect a conductive condition established between the first resistor and the second resistor, wherein one terminal of the first resistor in the longitudinal direction thereof is configured to be applied with a first constant voltage and the other terminal of the first resistor is configured as a first voltage detecting position, wherein one terminal of the second resistor in the longitudinal direction thereof is configured as a second voltage detecting position and the other terminal of the second resistor is configured to be either connected to ground or applied with a second constant voltage lower than the first constant voltage, and wherein the processing unit detects the conductive condition between the first and the second resistors in accordance with voltage values at the first and the second voltage detecting positions.
