1. An input device comprising:
- a cover sheet having an operation surface on a surface thereof;
primary input means formed below the cover sheet, capable of inputting coordinates; and
secondary input means formed below the primary input means, having a plurality of push switch elements, wherein the push switch elements are connected to a switch signal line, the number of switch signal lines being smaller than the number of push switch elements, and when the operation surface is pressed towards the secondary input means to enable one of the push switch elements and a switch signal from the switch signal line is detected, the enabled push switch element is determined based on coordinate data obtained from the primary input means.

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.
