<p>PURPOSE:To reduce a time to occupy a host computer, etc., and to improve the activity efficiency of the host computer, etc., by repeating scan in a device itself, and outputting only an input coordinate detected finally when a coordinate input operation is canceled. CONSTITUTION:A clock signal (a) is supplied from the host computer to a counter circuit 1, and the counter value (b) of the counter circuit 1 is supplied to a pulse generator 3, a coordinate detecting part 4, and a comparison part 5. The coordinate input operation is performed and the scan is repeated until the input coordinate is detected, and when the input coordinate is detected, the storage of a coordinate storing means 17 is rewritten, and the scan is repeated until no more input coordinate is detected. And when no detecting signal is detected by more, the input coordinate detected finally and stored in the coordinate storing means 17 is outputted to the host computer, etc. In such a way, it is possible to reduce the time to occupy the host computer, etc., and to improve the activity efficiency of the host computer, etc., using with another usage in common.</p> |
