Abstract

An input device includes a pressure-sensitive or capacitive planar input unit with an indicator sheet which has input sections being secured to the surface of the planar input unit. A tactile feedback generator is provided at the back side of the planar input unit. The tactile feedback generator includes dome-shaped inversion plates that are separately provided at locations corresponding to the input sections and provide feedback to the operator. When an input section is pressed, an operation signal in accordance with what is indicated at the pressed input section is generated.
