Abstract
A protection panel having a touch input function of the analog resistance film method for detecting an X-Y coordinate representing an operated position by a potential gradient based on a touch operation relative to the front substrate, in which the back substrateand the front substrateinclude contactsG andG, respectively, connected to each other in series on the resistance filmsA andA through the routing circuitsC andC to have potential difference, in which the contactsG andG face each other at a predetermined distance when the back substrateand the front substrateare connected to each other, and in which a switchis provided for detecting, when voltage is applied by the contactsG andG between the electrodesD orD of either one of the front substrateand the back substrate, whether or not the contactsG andG are brought into contact with each other based on voltage detected by the electrodesD orD of the other of the front substrateand the back substrate
