<p>PROBLEM TO BE SOLVED: To provide a touch operation input device which prevents foreign matter, etc., from accumulating and also allows even a person who has long nails to easily perform an operation. SOLUTION: The shape of an input pad 16 for inputting a touch operation of a touch tracer is made a projecting one and the input pad 16 is arranged projectingly from the outer casing of the touch tracer. Further, the input pad 16 is constructed by arranging plural pressure sensitive resistance elements 46 in a matrix shape. The plural pressure sensitive resistance elements 46 detect pressure when a finger touches them, and a touch operation position is detected by detecting resistance value that changes due to the pressure change.</p> |
