ABSTRACT:
Comprises a panel, and a coordinate control section that detects a point touched on the panel and generates a signal according to the detected point. The coordinate control section generates a coordinate signal that shows coordinates of a touched point, when one point touch on the panel has been detected. When simultaneous touches of two or more points on the panel have been detected, the coordinate control section generates a control signal that shows a control set in advance corresponding to the number of touched points.
