<p>PURPOSE:To obtain an input surface having high sensitivity, with a simple structure, by providing a protecting sheet which has placed an elastic body on 2 sides of the circumferential part of the input surface, applying tension to its protecting sheet by a rotating body, and limiting height of the protecting sheet by an adjusting base. CONSTITUTION:A protecting sheet 11 and an upper electrode 14 are made to adhere to each other, and the sheet 11 is held at a fixed and tight position from a substrate 20, by a small-sized roller 17 and an elastic body 12 such as a rubber band, etc. Also, vibration of the sheet 11 in case of input is protected by fixing pressure sensible rubber 16 and a lower electrode 15 to the substrate 20 by an adjusting base 18. Also, a gap 19 is formed between the pressure sensible rubber 16 fixed by the adjusting base 18, and the tight position of the sheet 11. In this state, a character, a pattern, etc. are inputted onto the surface of the sheet 11 by an input chalk 7, the pressure sensible rubber 16 is pushed by the upper electrode 14, upper electrode 14 and the lower electrode 15 are set to a conducting state, the inputted information is inputted, and when the chalk 7 has been detached from the surface of the sheet 11, it is restored to its original position by tension of the elastic body 12.</p> |
