초록

The coordinate detecting device according to this invention processes a plurality of detected adjoining input values scanned from an optical inputting grid and creates a single average value from the plurality which single value it provides to a host computer. It also evaluates data received from said optical inputting grid and restarts the scanning of the optical inputting grid independent of processing through a host computer when no input value is detected. It also receives and stores each input value received from said optical inputting grid, but doe...

청구항

A coordinate detecting device responsive to coordinate input operations for providing to a host computer coordinate values comprising: a counting circuit for providing at an output a series of counter values, having at least one reset signal input terminal, which, when when receiving a reset signal resets the counter to its beginning value and restarts said counting circuit; a coordinate detecting section having a counter receiving input for receiving counter values from said counting circuit and for effecting scanning of a plurality of sensing elements ...
