发明名称 POSITION DETECTOR, POSITION DETECTING CIRCUIT AND POSITION DETECTING METHOD
摘要 A position detector is provided including: a transmission signal supplying circuit for supplying a transmission signal to a plurality of conductors disposed in a first direction; a first conductor selecting circuit for supplying the transmission signal outputted from the transmission signal supplying circuit to a predetermined conductor(s) of the plurality of conductors disposed in the first direction; a differentially amplifying circuit for differentially amplifying signals inputted thereto through its first and second input terminals, respectively, and outputting a resulting signal; and a second conductor selecting circuit for selecting a plurality of conductors including at least three conductors located close to one another in a plurality of conductors disposed in a second direction intersecting with the first direction, supplying signals from the conductors located on both end sides of the plurality of conductors thus selected to the first input terminal, and supplying a signal(s) from the conductor(s) other than the conductors located on both end sides, respectively, to the second input terminal.
