Abstract
A multidirectional input device includes ring-shaped resistance element layer , first conductive layer and second conductive layer shaping in arcs corresponding to resistance element layer , and knob having ring-shaped protruded section D. Resistance element layer has at least a pair of electrodes and is formed on flexible insulating substrate . Protruded section D brings resistance element layer into contact with first conductive layer or second conductive layer when the knob is tilted. When a given voltage is applied to the electrodes and the knob is tilted, resistance element layer comes in contact with first conductive layer or 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.
