Claim:
1. A touch panel system including: a stylus pen for touching a touch panel which has M first signal lines (M is plural), K second signal lines (K is plural) which intersect with the M first signal lines, and (M×K) electrostatic capacitances formed at respective intersections of the first signal lines and the second signal lines; and a touch panel controller that detects a position of the stylus pen, wherein the stylus pen has: a driver that drives the M first signal lines to output a first linear sum signal based on charges, which are accumulated in the electrostatic capacitances, along the K second signal lines, and then drives the K second signal lines to output a second linear sum signal based on the charges, which are accumulated in the electrostatic capacitances, along the M first signal lines; and position detection means that detects a position of a target, which has touched the touch panel, based on the first linear sum signal and the second linear sum signal, and the stylus pen has:
