Abstract
Pen pressure can be controlled in detail only by a positional detection controlling side of a touch panel. Thus, pen pressure data will not be required to be transmitted from a touch pen to the touch panel, the touch pen itself will require no batteries, and neither the touch pen nor the touch panel requires a communication apparatus, thus reducing the weight of the touch pen itself and reducing the size thereof. Comprised is a touch panel system for measuring output signals of at least two adjacent sensor lines to obtain an input position (x, y) of an indicator and information (z) of a capacitance value from a difference value therebetween; comprising a pen pressure converting sectionD for converting the information (z) of the capacitance value into pen pressure data, wherein the input position (x, y) and the pen pressure data are transmitted to a drawing controlling section.
