Coordinate input unit
First Claim
1. A coordinate input unit for converting and detecting a pressing position in accordance with the coordinate to be applied into an electric signal, said coordinate input unit comprising a coordinate input pad in which one or more pairs of sheet-like electrodes for a function switch held by a pressure-sensitive, electroconductive sheet having weighed input sensitivity different from that of another pressure-sensitive, electroconductive sheet is laminated on a pair of flexible, sheet-like electrode groups for coordinate input having a plural number of electrodes in accordance with the pressing position and which is held by the latter pressure-sensitive, electroconductive sheet.

Abstract
The coordinate input unit is provided with a coordinate input pad in which one or more pairs of sheet-like electrodes for a function switch held by a pressure-sensitive electroconductive sheet having weighed input sensitivity different from that of another pressure-sensitive, electroconductive sheet, is laminated on a pair of flexible, sheet-like electrode groups for coordinate input having a plural number of electrodes in accordance with the pressing position, and which is held by the latter pressure-sensitive, electroconductive sheets. The described coordinate input unit allows to perform several input operations of coordinate input and using several function switches using only one hand.
