<p>PURPOSE: To provide an input tablet capable of precisely detecting a depressed position. CONSTITUTION: The input table is provided with a panel part 10a (e.g. obtained by sticking a transparent conductive film consisting of stannic oxide to a glass substrate) formed on the shape (e.g. a rectangle, a square and a parallelogram) of a prescribed area to be detected at its position and having prescribed area resistance rate and plural electrode parts 15a to 18a (e.g. indium oxicide (In2 O3 ) film obtained by evaporating indium metal on a glass substrate or parts obtained by screen-printing of carbon ink) electrically connected to the panet part 10a and arranged around the panel part 10a. The electrode part is divided into plural sections 15a, 17a, 16a, 18a along the periphery of the panel part 10a and a resistance value in each unit length in the divided sections is differentiated in each section. Consequently the distortion of potential distribution in the panel part 10a can be solved and misdetection can be removed.</p> |
