发明名称 COORDINATE LOCATION DETECTION DEVICE
摘要 <p>An objective of the present invention is to obtain a configuration of a coordinate location detection device with which it is possible to obtain adequate sensitivity even when enlarged. A coordinate location detection device (100) comprises: a first sensor electrode (Xi); a first capacitance detection unit (21) which is connected to the first sensor electrode (Xi), and further comprising an integral circuit; a second sensor electrode (Yj); a second capacitance detection unit (22) which is connected to the second sensor electrode (Yj), and further comprising an integral circuit; a coordinate computation unit (25); and a coordinate instruction device (30). When the coordinate location detection device (100) is in a first input mode wherein a coordinate location is inputted via the coordinate instruction device (30), a plurality of the first and second capacitance detection units (21, 22) detects a signal which is outputted from the coordinate instruction device (30), and carries out, in a unit detection interval, a charge by the coordinate instruction device (30) and an integral by the first and second capacitance detection units (21, 22), thereby detecting a capacitance. The coordinate computation unit (25) determines the coordinate location from the capacitance.</p>
