Abstract
A multidirectional input device includes ring-shaped resistance element layer, first conductive layerand second conductive layershaping in arcs corresponding to resistance element layer, and knobhaving ring-shaped protruded sectionD. Resistance element layerhas at least a pair of electrodes and is formed on flexible insulating substrate. Protruded sectionD brings resistance element layerinto contact with first conductive layeror second conductive layerwhen the knob is tilted. When a given voltage is applied to the electrodes and the knob is tilted, resistance element layercomes in contact with first conductive layeror second conductive layer, so that an output signal of a high resolution concerning a tilt angle can be obtained. The output signal is supplied to a microprocessor and calculated, then an angle or a direction is detected and recognized.
