Abstract
In a touch panel system () of the present invention, a stylus pen () produces output that indicates that a quantitative characteristic value is increased from the characteristic value of a previous output by using a waveform that corresponds to an (L+1)-th drive line (DL) other than L numbers of drive lines (DLto DL) and, meanwhile, produces output that indicates that the quantitative characteristic value is decreased from the characteristic value of the previous output by using a waveform that corresponds to an (L+2)-th drive line (DL) other than the L numbers of drive lines (DLto DL). A touch panel controller () includes a conversion output unit () that converts and outputs the quantitative characteristic value by using the sum of the initial value of the quantitative characteristic value and the number of outputs×the unit amount of increase or decrease in the waveform that corresponds to the (L+1)-th drive line (DL) or in the waveform that corresponds to the (L+2)-th drive line (DL).
