Title:
位置情報入力装置および位置情報入力方法
Document Type and Number:
Japanese Patent JP5375828
Kind Code:
B2
Abstract:
A position information input device is provided with input positions assumed to be some positions of the surface of a conductive object, one or more signal receiving electrodes provided in other positions on the conductive object correspondingly thereto, for receiving a positioning signal inputted to each input position, and a signal input transfer module for transferring the same positioning signal specific to the input position. A signal generation/output module is provided together with the signal input transfer module, for generating the positioning signal in which a plurality of signals having different frequencies are defined as one group. The position information input device calculates path resistance values between the input position and the signal receiving electrodes from the respective values of the positioning signals received by the signal receiving electrodes and specifies the input position from the differences thereof.
