PURPOSE:To simplify an input operation without using a form, by constituting the first and the second sheets of the input surface, of viscous surface, and making an input pattern floatable on the input surface distinctly, and restoring it to the original state by peeling off both the sheets. CONSTITUTION:On the input surface, the first flexible semi-transmparent sheet 1 is provided, and writing pressure put onto its sheet 1 is transmitted to the seccond sheet 2, an upper electrode 3 and pressure sensible rubber 4. On this pressure sensible rubber 4, a closed circuit is formed by dropping a resistance value of a part on which writing pressure is applied, and setting a space between the upper electrode 3 and a lower electrode 5 to a conducting state. A ratio of a current flowing in this closed circuit is detected by a detecting resistor 6, and a position detecting circuit 7 detects a position co-ordinate of an input point. An eraser 13 having erasing members 13A, 13B is moved between these first and second sheets 1, 2 to erase input pattern which has floated on the first sheet 1, and to obtain a state acceptable to the input again. In this way, the input can be executed without using a form, and the input operation is simplified. |
