<p>PURPOSE:To make a special pen needless and facilitate production to improve the operation efficiency, by using an input board obtained by laminating and assembling successively a carrier substrate, an insulating spacer, and an elastic resistance plate. CONSTITUTION:Carrier substrate 13 generated by causing a conductive layer to adhere to an insulating substrate, spacer 14 to give a fixed gap between elastic resistance plate 15 and conductive layer 13, and elastic resistance plate 15 where pairing electrodes x and x' and elelctrodes y and y' are formed in upper, lower, left, and right sides of a conductive rubber plate are laminated and assembled successively to constitute input board 1. When pen pressure weighting 18 of a character and so on is applied to point 19 of resistance plate 15, resistance plate 15 is bent easily, and position information of contact point 19 is output to device terminal 16 through conductive layer 13. Since resistance plate 15 is returned naturally to generate a fixed insulating gap in case of no character input, any output is not generated at terminal 16. By using the input board where resistance plate 15 is laminated through spacer 14 in this manner, an ordinary form can be used, and a special pen is needless, and operation efficiency is improved.</p> |
