ABSTRACT:
An input device contains a plurality of push switch elements that are connected to a single switch signal line. When a switch signal is detected from the switch signal line, it is determined which push switch element is enabled based on coordinate data obtained from a primary input sensor. By using the coordinate data, only a single switch signal line is used to determine which push switch element is enabled.
