INPUT DEVICE
First Claim
1. An input device comprising:
- a pressure sensitive detecting portion that includes a lower detection layer and an upper detection layer facing each other with a gap therebetween, and detects a contact position between the lower detection layer and the upper detection layer on the basis of a variation in resistance value; and
a capacitance-type detecting portion that includes a plurality of X driving electrodes and a plurality of Y driving electrodes which face each other with an insulating layer interposed therebetween and extend in directions orthogonal to each other, and detects a position where an indicator approaches on the basis of a variation in the capacitance between the electrodes,wherein the capacitance-type detecting portion is formed on the pressure sensitive detecting portion, and a flexible cover sheet is formed on the capacitance-type detecting portion,the upper detection layer is formed of a flexible resin sheet,the X driving electrodes, the Y driving electrodes, and the insulating layer are formed of flexible resin sheets, andthe upper detection layer and the X driving electrodes or the Y driving electrodes provided at a lower side are arranged in the vertical direction without a metal layer interposed therebetween.

Abstract
Disclosed is an input device capable of decreasing the number of layers of a detecting portion to reduce manufacturing costs and easily deforming layers provided above a pressure sensitive detecting portion. A capacitance-type detecting portion that detects the contact position of a finger on the basis of a variation in capacitance is provided on a pressure sensitive detecting portion that includes a lower detection layer formed on a lower base sheet and an upper detection layer formed on an upper base sheet. A voltage is applied to the pressure sensitive detecting portion and the capacitance-type detecting portion such that the application times of the voltages do not overlap each other. Therefore, it is possible to prevent interference between the detection operations of the two detecting portions.
