Abstract
A coordinate detection system capable of displaying relevant coordinates when operated with only one fingertip or like coordinate designator even during a repeat operation of the latter with no complicated designator manipulations required. The system comprises a coordinate detection apparatus and a coordinate output apparatus. The coordinate detection apparatus includes a sensor substrate to be operated by the coordinate designator, scan driving output units for generating a detection signal in response to the coordinate designator operation, and signal processing units for extracting tap and slide component data from the detection signal and supplying the extracted data to the coordinate output apparatus. The coordinate output apparatus includes a state detecting unit for detecting the state of the tap and slide component data, a measuring unit for measuring the tap component data, a mode changing unit for changing operation modes depending on the result of the measurement, a control unit for controlling the apparatus and a display unit for displaying various kinds of data. Operation modes are changed only if the tap component data is supplied in a predetermined state.
