<p><P>PROBLEM TO BE SOLVED: To provide a coordinate input system for preventing incorrect detection by contact or the like of a palm, in a coordinate input panel of resistance film type where the protective layer is made thick to improve the durability. <P>SOLUTION: In the input panel requiring high durability, a thick non-insulating resin film is sometimes used as the protective layer, but a coordinate shifted from the position specified by a finger can be input in response to influence of capacitance binding between the palm and a face resistance element. The coordinate input system has a calculating means for identifying whether the number of contact or proximity parts of a coordinate input region with a conductor such as the finger is one or two, thereby preventing incorrect detection even when the protective layer is made thick to improve the durability. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
