| 摘要 | PURPOSE:To detect easily the position of a depressing point, by opposing partial- deposition conductor parts where a slender potential gradient layer and an insulation layer are arranged alternately to a full surface conductive layer at an interval to apply sequentially a voltage to the potential gadient layer. CONSTITUTION:A gold thin film layer is vapor-deposited on a film 2 on a substrate 1 to form a transparent condutive film. Then, the potential gradient layer comprising the partial-deposition conductor parts 3, 3', 3''... is formed into a slender rectangular shape at right angles to the face of paper by chemical etching, electrodes 4, 4', 4''... and 5, 5', 5''... are formed at both ends and the electrodes 4-4'' are grounded all together. Then, a film 7 laminated with a detecting layer 8 having electrodes 9 around the layer 8 is arranged oppositely via a spacer 6. A desired point of the film 7 is depressed while applying sequentially a voltage to the electrode 5 to measure the time when the voltage is detected from the electrode 9 and the amplitude of the voltage. Thus, the two-dimensional coordinates are obtained easily and simply. | ||||||
